You can buy keyboards from lot of manufacturers but Keypad-FD providing reliability, long life and design flexibility. Our engineering team has been into this field since decades so no manufacturer can be in our competition. We always gives our best to our clients that is why we are the top most manufacturer right know. Well before getting into deep discussion, firstly we want you to go through the main definition of membrane keyboard so that you can do analysis about membrane keyboard pros and cons, this article will surely going to help you in choosing the right kind of keyboard.

A Small Intro to Keyboard

As we all knows that for all electronic devices and computers, keyboard work as a backbone. It plays an important role in its functioning. In simple words, it helps the person to control electronic device via typing.

In market, variety of keyboards is available but the most common keyboards are mechanical and membrane. But today we are going to put some shed to the main features of membrane keyboard, let’s go through it.

Overview of Membrane Keyboard

After playing lot of games and doing lot of work, everybody looks for an amazing keyboards that provides comfort to fingers but now all the keyboards almost gives a same look but few of them are the dream keyboards so you have to decide yourself which one will be good enough to fulfill your work needs by going through its all features. Slowly but surely, membrane keyboard has overtaken the mechanical counterparts and now have been the most common type of keyboard that we used to see around like in or our offices, schools, colleges etc.  Because of their popularity people now referred it as a most regular or standard keyboards.

The very first keyboard is called membrane keyboard, which is composed by 3 different flexible layers. First layer is known as top membrane layer, there is conductive trace under the top of layer, after pressing key it get you through the second layer which is composed of holes that let the pressure pads to pass through in order to create contact with conductive traces on the top.

There are two types of designs commonly used; first one is the flat key design used by micro-wave oven, keys printed on these pads are the same like it printed on the other pads with same pressure pads but it is difficult to use it for computer keyboard because it provides no physical feedback.

Dome switch keyboard are the another type of keyboard which uses a dome with printed letters. Such keyboards are only made by using rubber or silicone keypad with dome. When the dome is press, it collapse and the graphite beneath the dome fulfill the circuit, and also sends a signal that key has been pressed.

 

Advantages of Membrane Keyboard

Typing Experience of is almost similar to other Keyboards:

Dome keyboards are made by using rubber or silicon domes to respond, so there is a difference of typing between mechanical and membrane keyboard, but with time, technology is getting more advanced so this difference is now become very smaller.

Noiseless

When we compare this keyboard to others then we get to know that membrane keyboard does not create any noise while fast typing but other keyboards create huge noise. For example, mechanical keyboard with blue switches are very noisy.

But if you are one of those who love the loud noise while typing then you should go after the mechanical keyboard.

Portable

If we compare membrane keyboard with other like mechanical then we get to know that it is much lighter because of plastic material, one can do his work by having keyboard on its laps for hours with zero stress. It puts a very small load in fact a zero load on the person.

Affordable

Membrane keyboards are made by using common material with advance tech so because of this it is more affordable than other keyboards. Though it has same features than mechanical keyboard but the prices for membrane keyboard is less expensive, a common men can easily afford it.

Size

Another good pro of membrane keyboard is that it is smaller in size and more compact than others. Many manufacturers utilize these keyboards in 90% of applications because of their slim designs.

Longer Lifespan

Membrane keyboard comes up with longer lifespan because they don’t provide separate moving parts for the keys. So if you are one of those who is looking for keyboard for long use then you must try this one.

 

Disadvantages of Membrane Keyboard

With advantages, everything comes up with a few disadvantages; few of its cons are listed below.

Typing feel

Membrane keyboard does not produce any tactile feedback naturally and don’t produce spring like action as mechanical keyboard so many typist says that they need lot of effort and energy in typing, few of them also says that this keyboard also affected their typing speed.  But now technology has become more advanced and this typing difference has become very small now.

Cleaning Experience

Membrane keyboard is not easier to clean when it compares with other keyboards, its keycaps are non-removable which makes it harder to clean.

Note: This keyboard is not really popular because of slow typing speed but it is perfect in case you want any keyboard which provides protection from damage and dirt then membrane keyboard is the best one.

Few of membrane keyboard more features that you may have not known:

• It is very sleek and comes up with compact design because of this feature it can easily got fit into any electronic device.
• Its front overlay design can easily be made according to client’s requirement even the color combination can also be done according to their choices.
• It also provides embossing feature with outstanding look.

 

Applications:

• These keyboards are widely been used in Industrial Automation machine control.
• Their 90 percent usage has been seen in In Bio-medical equipment’s.
• Testing and measuring equipment’s are incomplete without these membrane keyboards.
• In aviation and all kind of process control, their great usage has been seen.

Our 90 percent applications and industry is incomplete without this membrane keyboard, we can took an idea that how much popular they are right now.

Which Keyboard you should choose?

Well! There is not anything that comes up with 100% pros, as there is pros there must be few cons with it, if you does not care about typing speed and keyboard performance or you are using it with laptop, tablet, using with PC or for office working or you have to travel a lot with your laptop, tablet then we will strongly recommend you to buy membrane keyboard because of its small size, compact design and light weight.  In addition you can afford it easily because of low prices but if you are a heavy user like freelancers who use the keyboard all the time or if you are developer then membrane keyboard is not of your type you must go on with a mechanical keyboard for yours fingers comfort but keep remember is very expensive so buy it only if you have good enough money.

Flexible Circuit – Everything you need to know about it

Keypad-FD has advanced facility and years of experience that enables our team to give the quick turnaround time on flexible circuit. Our team of engineers helped clients conceptualizes, designs, and manufacture complex designs effectively.

Before getting into deep conversation we would like to put some shed to the main definition of Flexible Circuit then we will take you through its brief discussion.

What is Flexible Circuit? A small Intro

Combination of many printed circuits and components that are placed on substrates is known as Flexible Circuit. Flex circuit boards, flex PCBs, flex circuits, or flexible printed circuits are few of their other names.  Same components are used to designed rigid printed circuit boards and flexible printed circuit boards.

But the major difference is that for manufacturing flexible circuit board, the board used in it is very flexible even can adopt any desired shape during process.

Structure of Flex Board:

These circuits are very thin and light weight with contoured shapes. They are composed of strips of metal which are conductive mainly copper, with dielectric material which is of polyimide. Because of it circuit can easily bend and can easily bear high temperature. They are very similar to printed circuit boards but it is more flexible. Connectors used by it are less expensive; it is another plus point for using such flex circuits. They are popular and widely used because it provides mechanical flexing at its best.  In short we can say that flexible printed circuit board tech offers many possibilities in terms of designs and attributes for many products. Now let’s have a look below to its brief discussion to have complete knowledge about Flexible Circuit Boards.

Let’s have a look to the types of Flex Circuit Board

 

There are many configuration and specification for designing circuit boards but they are divided on the basis of layers and configuration.

Classification of Flexible Circuit on the basis of Configurations

Flexible Circuit is classified into two types based on configuration.

1: Rigid-Flex PCBs: 

By its name we can get an idea that it’s a configuration of rigid and flex PCBs, in simple words we says that rigid-flex PCB configuration features a rigid circuits in a series that are held together by flex circuits. These days lot of manufacturers utilizes these hybrid circuits because it improves the capability of circuit and makes it more reliable.

Manufacturer used it for mounting connectors and components in the rigid areas while the flexible areas provide vibration-free resistance because of their flexibility. This type of circuit comes up with lots of more advantages so designers utilize these circuits fully especially for challenging applications.

2: HDI Flexible PCBs:

The full form of HDI is high density interconnect. These circuits are used for those applications which demands higher performance. These circuits are famous because they provide the best layout, construction and designs. One of the main features of this circuit is micro-vias. The main difference b/w HDI flexible PCBs and regular flexible PCBs is that HDI flexible PCBs utilize thinner substrate which plays an important role in utilizing the packaging size and also improves the electrical performance.

Classification of Flexible Circuit on the basis of Layers

Flexible Circuit is classified into four types based on layers.

1: Single-Sided Flexible Circuit Boards:

It is usually known as a basic type of flexible circuit board. It is composed of single layer of flexible polyimide film with a thin layer of copper. This is called single-sided flexible circuit because copper layer can be accessed only from one side of circuit.

2: Single-Sided Flexible Circuit Boards with Dual Access:

Well! this circuit is also a single sided but the main difference is that the copper layer can access easily from both side.

3: Double-Sided Flexible Circuit Boards: 

This circuit is composed of two layers on each side of base polyimide layer but the electrical connection is created by using metalized plated via holes.

4: Multi-Layered Flexible Circuits:

This circuit is composed of both single and double-sided flexible circuits. Connection b/w these circuits are created via plated-through holes.

Advantages of using Flex Circuit

Because of its benefits and amazing features Flexible circuit are so popular and widely used. We are going to put some shed to its main benefits, let’s have a look below to few of them.

Small Package Size and Light weight:

These are very light weight and easily can fit their body to any of the circuit because of flexibility. Its biggest advantage is that such type of boards are not only thinned but can also be creased easily. One can fold it and placed it to any area that is why we strongly recommend our engineers to utilize the benefits of 3D packaging geometry in order to facilitate the client with more package size reduction.

Accurate Designs:

These circuits are usually made by using automatic machinery so because of this; these circuits come up with zero error and 100% accuracy.

Freedom of Design:

Because of flexibility this circuit is not limited to 2 layers. Designers can makes lot of designs by using it. Major advantage of these circuit is that it can be made as a single sided with single access, single sided with double access and multi-layered also. Because of its flexibility it can be configured with lot of interconnections.

Possibility of High Density Configuration:

This circuit another good advantage is that it provides both -plated through-hole and surface mounted components. Because of this combination one can easily make high density combination and in such a way we can have a more free space for adding more components.

Flexibility: 

These circuits because of flexibility can connect with multiple planes while processing. During installation such circuits can flexed to variety of levels.

High Heat Dissipation:

Designer creates tiny thermal parts because of compact design which helps in dissipating the heat quicker. Another good point about this circuit is that it dissipates heat from both sides.

Improved Air Flow:

Because of flexibility and heat dissipation it improves the airflow.  Because of this feature circuit remains cooler and it’s performed for long life.

Durability and Long-term Performance:

This circuit is much better than rigid one because of its durability and long term performance. Such circuits can easily flex up to 500 million times. Because of Low ductility and mass, these circuits easily bear vibrations and shocks.

Reliability:

These circuits popularity is because of reliability, other circuit boards main problem was interconnection but now it is possible to design circuits with fewer interconnections.

Suitable for Application with high temperature:

Usage of polyimide material can bear high temperatures and provides high resistant against acids, oils, and gases. This is the reason that these circuit can even survive in applications with 400 degree centigrade.

Cost Saving:

Because of flexibility and small size it can be fit to any area which plays an important role in reducing overall assembly cost.

Few other benefits of this circuit are that they provide strong signal with 100% quality and reduced the wiring errors that is why flexible circuit seems very simple and easy to understand.

Material used for Flexible Circuit:

Material Selection is very important; if you are using a good material then the final results will be more effective.

Copper is widely used for such circuits so Keypad-FD will recommend you to go after this material. But Keypad-FD is also willing to give services by using materials with conductors such as aluminum, Electrodeposited (ED) copper, Rolled Annealed (RA) copper, Constantan, Inconel, silver ink, and more.

A Complete Guide to a Rubber Keypad (Use + Benefits)

In this Article we will take you through a complete guide to a Rubber Keypad, this article is a full package; here you will find everything from usage of rubber keypad to its benefits and features. Before getting though a deep conversation about rubber keypad let us put some shed into its main definition.

What is a Rubber Keypad?

As a beginner first you have to go through what is actually a Rubber Keypad? There are variety of rubber keypads in the market which seems similar to membrane switches but they just seems similar, in real both are totally different because membrane switches are made up of electronic switches with layers of membrane & graphic overlays on the other hand Rubber Keypads are made up of electrical switches and a rubber overlay.

The main difference b/w a rubber keypad overlay and a keypad switch membrane is thickness and texture just because of this overlays perform different purpose otherwise they are same.

If you are using switch membranes then you can easily engage with switch just with a little effort because of its thinness but in case of rubber switches engagement required a bit effort because of its thickness and texture.

Rubber keypads another plus point is that they provide favorable qualities and easily can be set in all types of product.

One can easily utilize it in garage doors, remote controls, elevator switches, game controllers and variety of applications and context.

Why Rubber Keypad is in a great use? Why it doesn’t need more care?

There are many reasons of it’s widely usage, we are going to write below of the great one. As everybody knows that silicone rubber keypads are non-transparent, this amazing feature let the light pass through it.

Because of its non-sticky and conveniently pressing feature, manufacturer use it in almost 90% of digital items. Just because of rubber keypad manual handling has become so easier.

If you are also one of those who are into finishing any digital item then we will strongly recommend you to utilize only a silicon rubber keypad.

But if you are looking for branded new rubber keypad then only try Keypad-FD.  Keypad-FD is serving their customers since decades with trustworthy interface at affordable prices.

 

Why Rubber keypad must be in Silicon?

 

There are many manufacturers that made keypads by using other plastics just to save some money and time but those keypads are not reliable and non-durable.

Because of non-corrosive and environment friendly nature of silicon it is most recommended material for Rubber keypads.  By using a silicon material your hands will not stick to keypad at all, it increases its lifetime, usability and makes it more reliable to use. One can use silicon rubber keypads in any type of environment. It comes up with 100% environment protection.

An amazing Guideline to Protective Coating for Rubber Keypad

Here I am going to put some shed into simple definition of rubber keypads protective coatings.

Protective Coatings

Coatings are very important for every product because of protective coating product value increases. Because of it keypad lifecycle increases and it offers amazing tactile operations and lot of finishing techniques. Just because of good coatings product can be safe from dust and even after heavy use there comes a very low chance of its surface change.

Varieties of protective coatings are available:

Applying a good kind of protective coating is extremely necessary; we are going to list down few good one coatings for rubber keypads.

Silicon Spray:

This coating is good for applications which are low or medium, one can coat it by using a spray and wear resistant.

If we compare wear resistant and screen printed coating then wear resistant is the good one.

If you want to double the abrasion resistance of printed graphics on rubber keypads then you must overcoat a silicon spray.

Clear Matte Protective Spray coating:

If you are going after Clear Matte Protective Spray coating then it provides the rubber keypad silky and smooth finish which keeps the application safe from dirt and there will be no chances of attraction of dust.

Clear Silicon Protective Spray:

If you are using Clear Silicon Protective Spray by adding anti-bacterial then it will facilitate you by wear protection and anti-bacterial resistant

Polyurethane:

These coating increases abrasion resistant of graphics by 20 times so this is also applied 100% of keypads.

Parylene:

This coating is applied to 90% of keypads; it has high resistance and good for high use application. It actually provides resistance to chemicals.

Epoxy:

This one is applied to only key tops but it is 100% wear resistance but can only be utilized for high use applications. Because of this coating key tops provides a feeling of hard plastic and lens effect.

Clear Coat:

This one is the one of the lowest cost protective coating and is only applicable for low use applications. Resistance is directly proportional to coating, if you do more coat, resistance will increases automatically.

Amazing Health Benefits of Protective Coatings

As we all know that Flue and MRSA spread very quickly every year, so many hospitals are looking forward to control it by adding antibacterial to all applications.

The antibacterial used in the sprays are produced by silver component, as we know silver is a biocide so work as a perfect antibacterial.

When this sprayed applications get in touch with normal atmosphere then it immediately evaluate silver ions which plays an important role in killing a microscopic bugs.

Many research found that because of these antibacterial coatings they found an immediate response of reducing bacteria’s just in a very short span of time.

You will not believe but yes just because of this coating many people remain safe from the spread of infection, cross contamination, and bio-film build up even after a heavy use results will be still the same.

After making rubber keypads protective coating is the only thing that provides ruggedness and longevity to keypad. Addition of protective coating is an amazing option to remain safe from many issues and situations. So if you want to place an immediate order for sliver rubber keypad then contact Keypad-FD, we will follow all safety measure to provide you efficient, reliable, environmental friendly rubber keypad.

Everything You Need to Know about Membrane Overlays – A Complete Guide

As a beginner first you need to go through what actually Membrane Overlays are? In this Article, You will get to know about Membrane Overlay Overview, Importance, and Features.

Membrane Overlay Overview

Membrane Overlays are the main part of membrane switches, these are actually a separate plastic layers made by polyester. Many people says that membrane overlays and graphic, panel overlays are same but here is a big NO to all of them, this is 100% wrong because of mechanical nature of membrane switches, membrane overlays are very much unique from panel overlays and graphic overlays. Membrane overlays actually represents the product identity, in short you can say that these are the face-plate to membrane switches.

Importance of Membrane Overlays for the Product

Yes! Membrane Overlays are very important for product, as we know it defines the product identity so it helps the manufacturers in getting know that how it will be easier or difficult to utilize the product.

Membrane Overlays are designed according to the design requirement of membrane switches, our engineer team will customize it as per your requirements.

Another important thing about membrane overlays is that it can be embossed to give tactile feedback and if necessary it can leave a space on the components of membrane switches.

If back lightening is involved then there might be a possibility of using variety of blocking layers for example fiber optics, LED’s, Electroluminescent.

These layers actually plays an important role in controlling the direction of light, one can even print the layers behind the colors of overlay. While doing this, there are chances of increasing opacity.

In order to maintain the quality of Membrane Switches, it is very necessary to use good material for Membrane Overlays. Let’s read about Membrane Overlays material and design guide.

Selection of Material for Membrane Overlays

Membrane Overlays material is the main concern while in its engineering, lots of materials can be used in its making but the best choice that will ensure the quality of membrane switch is polyester and UV exposure.

Advantage of using Polyester in Membrane Overlays

1: The main advantage of using polyester is that it can endure to survive millions of actuation’s.

2: Research says that it is best material for Overlay because it works as a solvent resistant.

3: It is one of the most robust materials that has superior life cycle.

4: Because of memory properties polyester requires hydro-forming than embossing.

Hydro-forming is more expensive for both tooling and unit cost that is why many manufacturers don’t use it just to save time and money.

Disadvantage of using material other than Polyester like Poly-carbonate

Many manufacturers uses Poly-carbonate because it is easy to print on, die cut and emboss. Its disadvantage is bigger than its advantages it begins to show signs of wear sooner as compared to other materials. Research has found that in many applications overlay of poly-carbonate lasts a minimum of 100,000 cycles during life cycle testing. If poly-carbonate overlay is un-coated then there are many chances of damage of product from other products. If poly-carbonate overlay is going to be in chemical environment then overlay will last no longer. So if you are not choosing a Polyester material then the final results will not be effective, even there are many chances of its breakage because of repeated pushing of switch.

While choosing a material another important feature that makes the Switches reliable is UV exposure, in case the material is non-reliable then the switches used in sunlight can be cracked So always try to choose the UV exposure material in order to ensure the quality.

Note: If you will take Keypad-FD services then we assure you that we will only choose reliable Polyester material in its making and let us know if the switches are going outdoors or indoors it helps us in choosing the correct Overlay material.

As we all knows that a well-designed membrane overlay makes a powerful first impression of company and equipment. If the company gives its best in providing unique design of the membrane switch overlay then this gesture will set your equipment apart from the competition by providing an unsurpassed user experience that is why we always do our best in choosing right material according to environmental needs.

Dependence of Few Factors while Printing Process of Membrane Overlay

There are three main factors that play an important role in printing process, the number of colors, color callout and the type of image to be printed. These days’ Solid overlays are one of the most popular options. For screen printing solid colors are still the best option but if you are one of those who want to generate same results as screen printing with less expense then digital printing can also be an option for those.  It is also a great option if you want your images to have halftones and gradient.

Note:

Either its screen printing or digital printing, the type of printing method used can be different from project to project. It depends on the color scheme, quantity needed, durability, wear ability. Try to go after a design that is robust as well as cost effective.

Why Keypad-FD is different than other Manufacturers in the Market?

Keypad-FD is different because we have indigo printer because of it we can generate all types of Membrane Overlay Solutions. We offer variety of solutions and our state of art technology comes up with printing unique serial numbers. These are readable by both human as well as computers.

Advantage of using Overlay in the Product

1: First try to know about the environment where you are planning to install the overlay, doing  this will maintain the product quality. If Overlays are made by using a right kind of material then the product will be more efficient, durable and reliable. Right material will provide you a lot of environmental benefits.

2:  As we all knows very well that most of the users want great usability in the product. Overlays play an important role in providing 100% usability to product. If you want to increase the product facility then always go after to the right type of overlay. Its functionality can be enhancing by adding more features into it for example usage of embossed technique and raised button.

3: Another main advantage of using Overlay in the product is that it is easy to understand, operate and feel.

4: It plays an important role in building your brand. If right kind of overlay has been used then the product will not break at all. As we all know that the right kind of visuals puts amazing impact on the product. Moreover overlay is the visual layout as well as the interface design so it helps to understand the product.

Reasons to buy Overlays

There are many reasons to buy Overlays; few of them are listed below.

Inventory reduction: There is no need to store the overlays at all. It is necessary only when the manufacturer demands it so you don’t have to pay the additional cost for it.

Easy Installation: They are very easy to install. They doesn’t required any rocket science, you can call the professionals they will fix it in a very short time but if you have a bit expertise then you can do at your own also.

Customization:  This is the main reason to buy overlays. Yes its customization offers lot of possibilities in terms of overlays. These are amazing for unifying variety of languages.

• electronic information
• digitization
• intelligence
• multi-function
• miniaturization and simple operation.

In these electronic information commodities, switches play an important role in sending command information and controlling circuits. Moreover, there are many types of such membrane switches. With the development of commodities, many different types of products have been developed,

such as:

1. tactile type
2. flat type
3. touch type.

The basic structure of the new membrane keypad manufacturer’s switch is relatively new to ordinary people, but its benefits and advantages are recognized by people.

What is the basic structure of the membrane keypad manufacturer’s switch?

The basic structure of this switch is relatively simple, which is mainly composed of

• the panel layer
• the surface adhesive layer
• the control circuit
• and the adhesive layer.

Each level has its own functions and characteristics. As well as its own special organization and requirements. Of course, the functions it plays are also different. Moreover, the panel layer is generally made of silkscreen, colorless light-transmitting sheets. Such as PET and PC with a thickness of less than 0.25MM.

Generally, Electrical membrane switch is a switch comes with printed contact circuit on conductive polycarbonate. It belongs to a contact switch. Similarly, it is a component of an electronic complete machine control system. Which integrates

• indicator windows
• and circuits.

What is the average service life of the membrane switch by membrane keypad manufacturer?

The average service life of the membrane switch can reach more than 1 million times.

It will be 5 times higher than the button switch. Furthermore, the most important thing is that the function of the membrane keypad manufacturer’s switch is completed by an elastic straight spring. Because the fluctuation of creep is very small, usually only 0.1 ~ 0.3mm plus reasonable use of materials. Simultaneously, it is still far from the compliance limit of the membrane.

So, the membrane keypad can accept more than one million times of restoring force. Similarly, it does not deform when pressed. And because it can move up and down to rebound, the wear is very small. The service life is naturally more than 5 times that of mechanical switches.

The service life of the membrane switch has increased from an average of 200,000 times to more than 1 million times. Similarly, the applicable range is from the previous limit to the current range. Moreover, the functional range is from the singularity of the first two to the current multi-functional diversity.

Most Popular features of membrane switches

custom membrane switches are very common in today’s society. It is an intelligent switching device. Which is very different from the traditional ordinary switches we used before. It brings us a lot of convenience. Maybe many people will not notice about such a small accessory. But it is such a small accessory that brings many benefits and convenience to our daily life.

Why custom membrane switches are popular?

Everyone can see this kind of membrane switch everywhere in our life. This kind of switch not only looks good, but also meets people’s demand for beauty.
The main reason is that the membrane switch plays a role in powering on and off the electronic commodities. And it has a protective effect on its products. It is no longer the phenomenon of the short cycle of the original button switch. The performance of the custom membrane switches is very stable. And the use cycle is often better than the product itself.

It delivers long term performance. So, there will be no need to change and repair several switches during the use of electronic products. which reduces us a lot of unnecessary troubles.
Our lives are inseparable from electrical appliances, so it is inseparable from membrane switches .

What are custom membrane switches?

 

Generally, a membrane switch is:

• a sheetof polyester film, called upper contact sheet and
• lower contact sheet,
• with a spacersandwiched between them.

The membrane switch is an electric switch with a structure that insulates the upper and lower contact sheets. With this spacer and presses the contact printed part from above to conduct electricity.

Membrane means “membrane”, and sheet switches that apply pressure film printing technology are called membrane switches.
Generally, by printing conductive ink on a polyester film with a silk screen, two types of contact patterns are formed:

1. upper contact
2. lower contact sheet
3. and an insulator (spacer) with a hole between them is formed.

custom membrane switches is a switch that is sandwiched and pasted. And the upper contact is pressed down to make it conductive.

Features of custom membrane switches

■ Compatible with diversified designs and thin and compact shapes

Because it is the operation part that can be called the face of the product. it can support various designs and coloring. It also supports design points such as design embossing. And click embossing and human interfaces.

Also, custom membrane switches outer shape can be tailored to the shape of a complicated molded case. And since most of the part is a laminated film, the total thickness can be made quite thin.

■ Selectable operation feeling

The click emboss is processed on the surface sheet. And a metal dome is mounted inside to give a click feeling. Or it can be turned on by simply touching a flat surface.

■ Easy to attach to equipment

Since it is a structure that is attached to the device, all you have to do is insert the switch tail into the connector on the internal board.

■ Noise interference can be reduced by shield printing

By printing a silver paste on the front side of the upper contact sheet. Measures such as static electricity countermeasures are possible.

■ Long contact life

Common problems in membrane switch design

1. Regarding the color problem, the modulation ratio of the ink is the main reason for the color deviation.And the color requirements are too strict. The color range is small. In terms of controlling costs of enterprises, to achieve a small color range, the cost to be paid is extremely high.

The cost of the product increases, and the unit price of the product will also increase accordingly. It is also difficult for customers to accept. So, for the color, the range must be within a reasonable range.

2. The bulging position of thecustom membrane switches button needs to be opened to a suitable position. Otherwise it will affect the appearance of the button. The adhesive is not sticky. In addition to the choice of raw materials, you must also confirm the shape of the prototype.

If the prototype has grooves, you need to choose good quality adhesive. The choice of adhesive is appropriate.

3. The shrapnel of the custom membrane switches drum pack button needs to be placed properly without deviation. Otherwise it will affect the operation of the button.

Custom membrane switches production and quality inspection

Membrane switch is indispensable in the production process of printing. If you do not make full use of printing technology, the appearance of the membrane switch is very flawed. With the continuous improvement of technology, printing technology is also rapidly improved.

Membrane switches are improved on the basis of traditional switches. Which largely change the structural problems of traditional switches. And have made great optimization and improvement in appearance and function.

Compared with traditional switches, custom membrane switches have outstanding characteristics such as:

• Thinness
• Lightness
• shortness, etc.,

so, they are favored by people in the market.

Membrane switch is a high-tech product. And it is also a new product. It needs to be strictly checked and inspected in terms of quality. For the inspection work of the membrane switch, we need to do it from outside to inside. Which means not only to check the color rendering and color quality of the membrane switch. But also, to consider the internal quality factors such as his life button.

The cable insulation resistance of the membrane switch also needs to be carefully checked.

Which items should be tested for the quality of custom membrane switches?

Membrane switch quality inspection is a very important task. For a successful membrane switch company, it is imperative to establish a complete quality assurance system. In the quality inspection of membrane switches.

In addition to the color rendering of inks familiar to screen printers and the color reproducibility of customers. It is more important to pay attention to the inherent qualities of custom membrane switches. Such as:

• button operating force
• life, peel strength and
• high and low temperature.

Constant temperature damp heat and return water line electricity, insulation, electricity, pressure and other indicators.

Nowadays, the use rate of this switch has become more and more widespread. Not only can it be seen in some hospitals or hotels, even in our daily lives. custom membrane switches are also very common. For example, microwave oven switches or some remote controllers have gradually adopted this new type of switch. So, what is the reason for the increasing application of this switch?

• First of all, it is naturally its good nature.
• The seal and water resistance of this switch are compared.
• so,in some humid environments, this switch can also work very well.

Second, the service life is relatively long. Because the deformation caused by each button is relatively small. So, the wear caused is also relatively small. The service life of this switch is much longer than the ordinary switch.

It is for these reasons that the use of custom membrane switches are becoming more and more recognized by everyone

Common problems in custom membrane switches circuit design are as follows:

1. The shrapnel of the membrane switch drum pack button needs to be placed properly. And there must be no deviation. Otherwise it will affect the operation of the button.

2. Color problem: The modulation share of the ink is the main reason for the serious color error. The color requirements are too strict and the color scale is too small. Therefore, these are factors that are difficult to control in any industry.

3. The bulging position of the button: the appropriate position for mold opening is required. Otherwise it will affect the appearance of the custom membrane switches. Moreover, the adhesive is not sticky. In addition to the selection of raw materials, it is necessary to recognize the shape of the good prototype. The choice of adhesive is appropriate.

An ultimate guide to understanding rubber keypad popular tips and tricks

What is a custom rubber keypad?

The change of custom rubber keypad has made many electronic products have a deeper reference to the definition of rubber. Rubber keys have also become indispensable auxiliary tools for electronic products. Rubber keyboards are also one of the keys.

 Its largest advantage is:

• environmental protection
• dustproof
• provides good protection for the keys
• can be carried away at any time in any environment
• provides silent tapping for the input device of the computer
• light and comfortable feel

The main design adopts mold design and development molding. Therefore, custom rubber keypad manufacturers design simple and convenient rubber buttons during the design.

 

What is the difference between silicone products and rubber products?

In daily life, many commodities are all silicone rubber products or rubber and plastic products. Sometimes no one can tell which category it belongs to. Many people mistakenly think that silicone is a raw material. Rubber and vulcanized rubber are not the same.

From the perspective of organic chemistry, silicone rubber products are liquid rubber and plastic products. These belong to single-component indoor temperature vulcanized rubber. It is a polyurethane elastomer raw material. That has silicone material as raw material.

Silicone rubber products are a type of silica gel. It belong to the liquid rubber and plastic products of single-component indoor temperature vulcanized rubber. Once exposed to air, the silane in it will produce a:

• condensation reaction
• a network structure
• chemical cross-linking of the management system

It cannot be melted. Its heat transfer performance is slightly higher than that of ordinary custom rubber keypad and plastic products. Once it is solidified, there is no way to separate the bonded masses.

Computers are quite popular now. Maybe we used to go to Internet cafes without a computer, so a company may not have enough staff! However, it is not an exaggeration to say that one computer can be reached nowadays. Some companies can even say that there are 100 computers and only 50 people. It is not a blow to technology to change lives! When we usually use computers, do we often encounter such problems? Is there dust in the slits of the keyboard? Is there something dirty? Not clean at all? Yes, these are very common questions!

How does custom rubber keypad manufacturer meet the market requirement?

 

In fact, the custom rubber keypad manufacturer is sometimes difficult. For example, the requirements of certain products are strict. Especially the built-in cannot have stains or impurities. It is a quality problem that cannot exist for rubber gifts. And this problem must be solved.

Difficult to say, there are difficulties. But also to pay attention to the simplicity!

First of all, it is necessary to understand how there are stains and impurities in rubber products. It will greatly affect the quality and appearance requirements of the product. This is an inappropriate product for buyers and a waste product for custom rubber keypad factories.

How to avoid it This one seems to be the difficulty of a small problem. I think many manufacturers should have done a lot of work in this area. Some of them have succeeded and of course failed. In fact, the main problem lies in the personnel to solve this small problem.

First of all, what should we make on the personnel? This is naturally training. The so-called corporate culture and philosophy must be there. If the quality concept is not unified or even not there, then things must be done badly. So, the training of the personnel should also be down.

 Let custom rubber keypad manufacturer have a concept of quality! Do not blindly pursue speed! Pay attention to the problem of stains in every link.

 

Secondly, in the first step of equipping materials. We must also check whether there are impurities in the materials when incoming materials. If the raw materials are not checked, then the probability of impurities in them will greatly increase. After checking the raw materials, when color mixing employees also need to pay special attention to the problem of impurities.

• First of all, the rubber mixer must be kept clean.
• And various cleaning tasks must be used to clean or
• clean the machine to prevent dust and small impurities
• that are not visible to the naked eye!
• After the rubber mixer is cleaned.carefully check whether the color masterbatch is clean during color mixing.

What things to consider before developing custom rubber keypad?

There must be no dust or other things inside. Especially the color masterbatch is very difficult to see because of the color. This is a careful job. It must be done carefully. After finishing the work with raw materials.

custom rubber keypad manufacturer should also pay attention to the actual production of the vulcanizing machine. That is:

1. the cleaning of the mold and
2. the impact of the working environment.

Rubber products are generally completed through the mold and vulcanized rubber.

 

What is an ideal custom rubber keypad working environment?

 

Working environment

• There must be no wind in the air, and
• try to keep the air as clean as possible without dust,
• because it is easy for the dust in the air to enter the raw materials, so it is difficult to think of the beautiful appearance of rubber products

It is also an important part of attention! Pay attention to the cleaning of the countertop during subsequent manual operations.

Are you annoyed by the lack of computer key hype when you go out? Are you also worried about the waterproof performance of the keyboard? This custom rubber keypad has a good effect on laptop control. when you are out and can easily carry music in any environment.

Putting the volume in our pocket saves a lot of space when we go out. When a quiet environment is needed, the keyboard knocking sound is too loud. It can be used to reduce the sound of pressing the keyboard when it affects others. Due to its light design , the material is soft, without any noise, so he is also called a silent keyboard.

 What are the major functions of custom rubber keypad?

There are many functions of the rubber keyboard. It has been well evaluated in the market. But good evaluations are designed with good material properties. Its selection is made of:

• food-grade rubber products
• non-toxic and tasteless
• rubber manufacturers can Add various colors that can also be customized according to customers’ favorite colors.

Adding various colors will not have any impact on environmental protection. The comprehensive design and collection of raw materials allow it to be:

• well applied
• preventing water seepage and dust-prevention
• Oil-proof and even acid-base, work alone at night will not affect the rest of the family because of noise
• it made of rubber raw materials and

In daily life, people use a variety of plastic appliances. Plastic products must dissolve for 400 years. Plastic waste has already become a key gossip of environmental degradation. We want to change this situation from the beginning when rubber products use instead of plastic appliances. custom rubber keypad products have gradually become a necessity for people to eat, drink, and live.

Effective Tips for Choosing the Right Membrane Keypads

When it comes to the Human Machine Interface, membrane keypads play a vital role. They are responsible for the functionality of these machines. Therefore, they need to be of the highest and the finest quality. Unless the HMI has a touch screen, it is most likely to depend upon a keypad.

There are different types of membrane keyboards available. These keypads serve the same purpose, but they do not have the same functionality. The good news is that today, we even have access to the touch keypad membrane.

With a wide variety of keypads, choosing the right one can be a daunting task. Nonetheless, you do not have to worry about it. In the course of this article, we are going to talk about the basic types of keypads and choosing the right one.

Different Types of Keypad Membrane

You have membrane is the most common type of keypad. You will find it in almost all household appliances. In addition, they are part of most commercial applications. A typical membrane consists of 3 basic layers. The top layer, a space layer, and a back layer.

Each of these layers serves a certain purpose. For instance, you notice the key printed at the front and the labels on the top layer. Likewise, the back and the space layers feature conductive stripes. For the HMI or the computer to register keypress, the operator needs to press down the key.

This results in getting both the upper and bottom layers together.

Dome-Switch Keypads

Another interesting and widely popular keypad type is dome-switch. You will find it most in commercial applications. Dome-switch keypads are a combination of mechanical switch keypads and a flat panel membrane.

It features a dome-shaped switch that incorporates silicone keypad with two circuit board traces embedded under it. Since these domes create tactile feedback, therefore they are popular among work-related and commercial applications.

Furthermore, these switches have a high-reliability level. They tend to last for as many as five million cycles.

Capacitive Keypad

These keypads greatly differ from other keypads. They use capacitance technology in order to register a keypress. So, when a user presses a key, it results in enabling the capacitance of the capacitor pad. These keypads generally have an aluminum finish. Also, they use foram element keys.

Despite the lack of popularity, capacitive keypads are something a viable choice for a number of applications.

Scissor Switch Keypad

Scissor Switch keypad is another popular type of switches. Its name is self-explanatory. The keypad features keys that look like scissors. Every key has two separate plastic pieces. These pieces are lock together like scissors.

In addition to these scissors like pieces, the switch incorporates dome-like rubber. It is something similar to the dome-switch keypad. However, scissor switches have improved functionality mainly because of the scissor design. The design keeps the keys connected together.

The manufacturer uses multiple ways to create effective scissor-switch keypads, but the most famous is the 3-layer scissor switches. Although scissor switches offer a number of benefits, they do have some downsides.

For instance, scissor switches are inexpensive in comparison to both dome and membrane keypads. In addition, these keypads have the ability to accumulate dirt and debris under the keys. Thus, resulting in a shorter lifespan of the keypad.

Nonetheless, with regular cleaning, you can drastically improve the lifetime of the keypad.

How to Choose a Keypad?

Now that you have an idea of the basic keypad types. Next, you need to know some important factors that would influence your keypad choice. You can go with membrane keypad or capacitive keypads; it all depends upon your requirements.

Silicone Rubber or Mechanical

Depending on the material that a manufacturer uses to create keypads, mechanical and silicone rubber are the two main categories. Most of the keypads fall under one of these two categories. If you want your application to have hard plastic-like keypads, then you should go with mechanical keypads.

On the contrary, for an elastomeric keypad, you need to choose the silicone rubber keypads. These keypads allow flexible and soft construction. It is possible to bend them without breaking them.

UV Coating

There are certain keypads that come with an ultraviolet (UV) coating. We generally call these keypads the UV keypads. These keypads have an additional printing on top of the foil substrate’s top layer. The layer is the UB resin layer.

The manufacturer would add the decorative graphics to the second layer of the foil substrate.

Tactile Feedback

Tactile feedback plays a vital role when choosing perfect membrane keypads. A keypad that completely lacks the tactile feedback is bound to cause type and input errors. Of course, when the user does not recognize any response against the keystroke, he or she is bound to make mistakes.

Tactile feedback, on the other end, helps create a physical sensation against the keystrokes. It gives the user the satisfaction that something has happened. With tactile feedback, after your press the keys, then they pop right back up with moderate force.

In case, there is no tactile feedback, it means you did not press the key all the way down. So, to give the command, you would have to press the key again. A good example of keypads with tactile feedback is your laptop keyboards.

Key Height

Key height is another important factor that requires consideration. There are certain keypads that have a higher key height in comparison to others. The key height has a direct impact on the tactile feedback of the keypad.

The higher the key, the greater the tactile feedback and vice versa. However, it is important to maintain a certain height. If the keys are very tall, they would be extremely uncomfortable to use.

Backlighting

If you are looking for a keypad for your workplace, we would recommend that you go with a backlighting keypad. Generally, the manufacturers use LED bulbs behind the keys to brighten them up. The light-emitting diodes are perfect to type in the dark.

In addition, the manufacturer often uses them in combination with light guides. With light guides, the light is evenly distributed. Thus, it results in light uniformity and power consumption. Something, everyone wants to have.

Choosing Membrane Keypads for Outdoor Use

When choosing a keypad, you also need to focus on the environmental aspect. Some keypads might perform exceptionally well indoor, however, they fail miserably outdoors. Therefore, to ensure the success of your keypad for outdoor use, you need to consider the following factors.

Durability

Durability is another feature that you need to focus on. There is no denying that keypads that are installed outdoor tend to wear down earlier in comparison to keypads that you install indoor. Mainly because outdoor keypads have to face harsh weather conditions.

Something the indoor keypads are safe some. Therefore, when choosing an outdoor membrane keypad make sure that is durable and robust. It should have the strength to withstand outdoor wear and tear.

Water-Resistant

Water-resistance is among the most important feature, especially for an outdoor keypad. It is imperative for the keypad to have been water-resistant. In case, you are placing the device in the relatively covered area, however, you won’t be able to stop the moisture vapor to get to the surface.

In some cases, it might settle underneath the keys, thus damaging the entire electrical circuits. Fortunately, all membrane keypads, even some touch keypad membrane are water-resistant. The reason being, their design of being embedded into the circuity.

Nonetheless, we should recommend that you double-check the keypad for being water-resistant before installing it outside.

Back lights

Backlighting is another feature that you should incorporate for your outdoor keypad. Of course, it is an excellent feature for any keypad in general. But in the case of outdoor, it can be really handy especially when the sunsets.

At night, when there is no sunlight, a backlight keypad would make it easier for the consumer to distinguish between buttons. It would ensure typing accuracy. The backlighted membrane keypads offer visibility and ease. It allows the operators to see clearly and avoid any sort of errors.
