Excellent tactile feedback.

Water and chemical resistance can be used for a long time in a humid and outdoor environment.

Backlight selection can shine in the dark. Because of laser carving. The product can make the button or logo appear transparent.

P+R

Precautions for rubber keyboard:

Snap Ratio: The Snap Ratio of the keyboard will affect the tactile feedback and product life. Generally, Niceone-tech recommends that the Snap Ratio be controlled at 40%-60%. If it is less than 40%, the life will be longer, but there is no feeling. In China, we will also call it a trip. The lower the trip, the longer the life span and the worse the tactile feedback.

Shore: The hardness is best to choose 30A-85A, if it is lower than 30A, the defective rate is higher and the product cost is more expensive. If it is higher than 85A, the silica gel is hard and easily broken.

Conventional rubber keyboard processing:Usually, PU or hand-feeling oil makes the printing life of the silicone surface longer.Epoxy treatment: The product becomes more beautiful.Conductive or non-conductiveMultiple color optionsPhosphorescent “glow-in-the-dark” material additivesSilkscreen printed keysLaser-etched keysHard coatingEpoxy coatingEnvironmental shielding optionsPrinted or laser-etched legendsPrinted circuit board assembly

PCB Membrane Switch

The glass fiber cloth in PCB (or printed circuit board) is one of the raw materials of copper clad laminate, which is woven from glass fiber yarn, which accounts for about 40% (thick board) or 25% (thin board) of the cost of the copper-clad board. Therefore, PCB laminate models include FR-4, CEM-1, and G-10. The most commonly used material for PCBs today is FR-4. Simply put, PCB is the most important body of electronic components.

Advantages of PCB Membrane Switch

Niceone-tech believes that although the PCB membrane switch will be more expensive than the silver flex membrane switch, it can still be used in a large area because some of the performance of Silver Flex Membrane Switches cannot meet customer needs. One of the reasons is the welding of electronic original parts. The reason why many silver flex membrane switches are not suitable for installing too many electronic components is that the printed silver circuit and PET cannot withstand the high temperature of welding, but the PCB membrane switch can weld various Components and can withstand high temperatures. The second reason is that absolute pressure, vibration, or shock may damage some components of the screen printed membrane keyboard such as LEDs, but PCB membrane switches can overcome these problems.

Niceone-tech believes that PCB membrane switches are better than Silver Flex membrane switches in several places:

The resistivity is relatively low and the conductivity is high. Because the PCB is gold, tin, and nickel plating.

Use in an environment of absolute pressure, high vibration, and high impact

Compared with the high-resistance and high-defect of the hole filling of the Silver Flex membrane switch, the plated thru-hole resistance of the PCB will be lower, and the defect is also low. It is important that Niceone-tech can solder a large number of electronic components behind the PCB. Ideal for smaller designs where dense circuit patterns or trace routing limitations exist, by using plated thru-hole technology to utilize both sides of the PCB.

Different types of components can be soldered on the circuit board and are more robust.

Support hard soldering

Single-sided, double-sided, and multi-layer designs available

The most common design features include:

The buttons on Graphic overlays are convex embossed, rim embossed or debossed.

The screen printing method of the product includes digital printing, screen printing or a combination of the two.

Different textures and surface finishes include the Gloss, Matte, Velvet.

It can have a non-tactile touch or polyester or metal shrapnel touch.

LEDs window can use different transparent colors of raw material color or silkscreen.

Transparent white is a more common choice.

The LCD window can be selectively textured and treated with UV hard coating surface

EMI/RFI

backlit membrane switch

In addition to the price, the PCB membrane switch has no advantage, the basic PCB membrane switch performance is completely beyond the Silver membrane switch.

Metal Dome Switch

Metal shrapnel (Shrapnel for short) (because its switch is like an upside-down pot, it is commonly called Guozi slice, or 'pot slice'), also metal dome in English, made of stainless steel, is an important part of the switch.

With the help of the conductivity, the metal shrapnel acts as a high-quality switch between the user and the product. At the same time, the stable resilience of the metal shrapnel (automatically reset after pressing) is leveraged.

Materials for making snap dome and triangle or four-leg metal domes:

The metal dome switches and snap dome are sure to be the switch button. If the various switches are separated from the Metal Domes, it loses its meaning, so it is said that the Metal Domes plays a key role in the switch, and it was later known as the metal dome switches and snap dome.

Application of a metal dome: used on button switches, membrane switches, tact keypads, self-locking switches, metal dome switches, and snap dome.

Function of metal dome switches: to power on and off, which can give the operator good tactile feedback.

Originally, there is no professional name called snap dome in the early days. And a snap dome is made of metal material. Because it is a dome, it can bounce upward and be concave downward (convex and concave). Its initial state is convex upward, and it will concave downward when the operator exerts a force, and then rebounds after the force is removed. This kind of elastic metal material is uniformly called metal dome or snap dome. Later, when metal dome switches were introduced into China, many people were used to calling them metal dome switches. Metal domes also referred to as metal snap domes or tactile metal domes

Custom-made metal dome stickers of different shapes are widely used

There are four main shapes of Metal domes: triangle, circle, ellipse, and cross, with 1, 4, and 5 contacts on the top. The stickers of Metal domes should be customized according to individual needs, do not use them randomly, and avoid affecting the quality of the products. It is very convenient to assemble the stickers on the pot, and it is enough to attach a full version. Of course, pay attention to the stability of the conductive parts of the pot and the circuit board.

Metal domes are mainly in the size of 4MM, 5MM, 6MM, 7MM, 8MM, and 9MM. With a strength of 100-600gf (the strength depends on the customer's product needs), triangular pots are widely used and involve all aspects of our modern life.

The size of the pot is different. The strength can be set to large or small. If special requirements are required, special materials can be used. The strength can reach about 3000gf. The triangle has three feet and a vertex. The legs of the triangular pan can be long and endless, these are determined by the needs of customers.

Metal domes are mainly used in circuit boards, tact switches, micro switches, key switches, pc boards, and other products. It has the characteristics of stable contact, good continuity, and excellent rebound feel. The triangular pan-shaped piece is an excellent accessory used in major electronic products.

About the pot pieces:

The pot pieces can be tinned, silvered, gold-plated, and other different surface treatments. Different treatments on the surface can produce different effects. For example, tin plating can solve the problem of heating without fading. In addition, gold plating and silver plating on the surface will increase the pot pieces Gloss has a certain resistance effect.

About the pan-shaped pieces:

The pan-shaped pieces are generally made by customers with drawings provided by us. The types of pan-shaped pieces most used by the guests are round pieces and oval-shaped pieces, also known as waist-shaped pieces and cross-shaped pieces. Triangular pan slices and rectangular pan slices have diameters from 3mm to 20mm, strength from 100gf to 600gf, and special strength pans can reach 6000gf.

The back of the pan-shaped piece can be dotted or not, the round pan-shaped piece is generally five contacts, and one contact, some special needs no contact. In order to facilitate assembly, the pot pieces are generally stuck together with PET, which not only facilitates assembly but also accurately positions.

About its different names:

Metal domes are also known as metal shrapnel. Its English name is meal Dome slices. Sometimes people will say membrane switches. The name of Metal domes is generally based on his purpose. The ones commonly used in industry are called The shrapnel, and used in mobile phones, the keyboard is called the potsticker, and the switch series is called the membrane switch. Single-layer potstickers are generally full-page stickers.

Advantages: agile operation, fast assembly, disadvantages: bad experience for customers, no dustproof function, easy to be invaded by dust, and cause contact problems. Therefore, the single-layer pot-shaped pieces are becoming smaller and smaller in the market. Only when the Tiebei sealed machine does not require the protection and operation of the pot-shaped pieces, the whole-plate stickers and single-layer structured pot-shaped pieces will be used. The advantages of Double-layer film potstickers are: dustproof, durable, good feel, etc.

Disadvantages: high cost, slow assembly, etc. Double-layer membranes are widely circulated in the market, and almost all electronic products use double-layer structure pots, such as gaming keyboards, medical equipment, and even as small as remote controls. The single-layer metal dome picture below: The application of Guozi films and Guozi film stickers are becoming more and more widespread, and currently involves all aspects of life, such as the induction cooker we use for cooking, TV, air conditioning remote control, mobile phone equipment, bank U shield, cash machine, medical equipment products, various A series of buttons, touch switches, and other products are used in the pot.

Metal dome: the part to complete the work on the pan film switch

Metal dome is widely used. The metal dome is also the most important part to complete the work on the membrane switch. The main function of the metal dome is to contact and disconnect the power supply. Metal dome is generally made of SUS301 or 304 material. The life of the metal dome is generally over 100,000 times. The strength is determined by demand. Do not use it under too high temperature. Excessive temperature will seriously affect the service life of the metal dome.

The metal dome is used on the membrane switch to play a conductive role, conducting the two-pole contact of the membrane switch and rebounding by its own elastic force to complete the power-on and power-off functions. It is energized when the shrapnel is down and powered off when the shrapnel rebounds. Give the customer tactile feedback during the rebound process, with a certain feel (Note: proper operation, excessive back and forth movement may cause the switch to lose response).

There are many common causes of failure of shrapnel:

The operation is too frequent.

The pressure is too large, the stroke is too high.

The isolation layer is too thick.

The operation force is too small.

The effect of these reasons on the membrane switch is that if the shrapnel is forced too hard, the shrapnel cannot spring back, resulting in a continuous path, which means that the metal dome has been working.

The too-frequent operation causes the switch to malfunction and does not work for a short time. Excessive pressure will directly crush the shrapnel and keep working or not working. If it is too large, the metal dome may not be able to complete the work.

Therefore, the factors we need to consider when applying metal dome to the membrane switch are whether the metal dome can withstand the pressure of this product, whether the stroke is consistent with this product, and the isolation layer should not be too thick.

Metal domes are not without a fixed shape and size. They are a kind of custom-made products that can change the shape and size according to the needs of the product. The specifications and sizes of commonly used metal dome or snap dome are:

Specifications of the round snap dome:

Size: 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm. Round keys currently with these shapes are much used by customers.

Strength: 90gf, 100gf, 130gf, 160gf, 180gf, 200gf, 220gf, 250gf, 260gf, 280gf round keys. The most used strengths are divided into these types

Appearance: there is one contact on the top, four contacts, and five contact buttons, and there are also no points and one contact on the top. The three-snap points are evenly distributed on the edge. The round metal domes are all the key shrapnels with the shortest stroke in the shape of the metal dome.

Specification of triangle snap dome:

Size: 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm. Triangle key shrapnels currently have more customers with these diameters.

Strength: 130gf, 160fg, 180gf, 250gf, 280gf, 320gf, 350gf, the pressure of the triangular pot is generally these types.

Appearance: the triangular snap dome has two kinds of feet and no feet. The triangular key springs with feet can be directly welded on the PCB board. There are two kinds of points, one is with one point The species is one point among the three surrounding points.

Specification of the cross-shaped snap dome:

Size: 5mm, 6mm, 7mm, 8.4mm, 10mm, 12mm, 13mm, the cross-shaped snap dome customers use more than 7 diameters.

Strength: 130gf, 180gf, 220gf, 280gf, 350gf, 400gf.

Shape: there are no dots, there is one dot in the middle, four dots at the top, and four dots at five dots.

Specification of the oval pan and quadrilateral snap domes:

The oval and quadrilateral rectangular square pan slices are used together because they have no significant difference in shape and size.

Size: 3mm, 3.5mm, 4mm, 4.5mm, and 5mm.

Strength: 100gf, 130gf, 140gf, 160gf, and 180gf are the most used by customers.

Shape: there are no dots, one dot, four dots, and five dots on the surface.

Notes: It is more common for triangular pans to have feet, and for round shapes, there are also buttons with feet. Relatively speaking, the round pan pieces have a shorter stroke, the cross-shaped pan pieces have a larger stroke, the ellipse has a smaller diameter and less force, and the triangle has a shape that can reach a higher level. It can reach 3000gf, and all the pots can be silver-plated or tin-plated. The life of pots of different shapes can be the same. The life of pots in China is generally between 100,000 and 700,000 times.

If you need customized shrapnel, please contact us, as a membrane switch product factory, we can also export customized metal dome layer according to customer needs.

Membrane Switch Panel

Membrane panel is a type of HMI, in which the structure is generally PET, PC, PVC as the base material, DT, Nitto or 3M as the adhesive material to assemble them together. It is a kind of HMI with more prominent performance and lower prices.

Membrane switch panel is the operating system on many electronic controllers, medical accessories, agricultural products, and it is also the first interface. Color matching and design are particularly important. Fortunately, Niceone-tech's engineers and designers are very good at this type of product. At the same time, we will strictly review whether the customer's drawings and ideas can be realized.

Membrane Switch Panel Get in touch

Advantages of Niceone-tech Membrane Switch Panel

At this time, there will be two types of printing methods to overlay the top structure of the membrane panel. Using different screen printing methods will affect cost, usability, and durability. A poor printing method will make the panel coating of membrane switch overlay easy to peel off. Therefore, Niceone-tech has always been committed to quality, and we will pass the 100 grid test every time the screen printing and color printing are performed to prevent the product from peeling off the coating. Fortunately, Niceone-tech has mastered the core technology, which makes the product ink and circuit-level ink have high viscosity characteristics, and the above problems will not easily occur.

The CMYK color printing method can form gradual patterns or colors. Generally, we call this kind of digital membrane switch. The gradual color is not possible with conventional screen printing. At the same time, because color printing is very suitable for bulk goods when the quantity is large, the use of color printing will reduce the cost, but the color error of color printing will be larger. However, the general panel is produced by CMYK color printing. If it is a PET circuit, screen printing is still required.

Screen printing, the most commonly used printing method for membrane switch, uses ink debugging to produce a variety of colors, endowing the products with different colors. But when more colors are involved, we need more screens to create images. Meanwhile, Niceone-tech will choose different screens to produce different circuits to achieve high-precision and low-error circuits products. Screen printing is suitable for small batch production, and it also has higher color requirements and lower error rate. Even sometimes we will adopt the combination of screen printing and CMYK color printing so that a high-quality digital membrane switch with advantages of the two can be formed.

The membrane switch panel is generally thin, if not specially required, the thickness is controlled between 0.7-1.2mm. If the material is too thick, Niceone-tech will advise customers to use stainless steel molds, otherwise, the shape cannot be punched out. Even because the material is too thick, die-cut tooling cannot be used for punching.

Membrane panel:

With a sealed surface, easy to clean and affordable

Can be customized in various shapes and surfaces

Has a big application scope

In recent years, Niceone-tech is committed to researching and developing new types of membrane switches. LGF membrane panel not only has the life of fiber membrane panels but also cheaper than EL membrane panels. At the same time, its uniform luminescence and long life make it very popular in European and American countries.

On this basis, we have also developed a Resin dome membrane switch, the main feature is that the appearance and buttons are very beautiful. But the price will be relatively high, and the thickness will be thicker.

What can Niceone-tech could do?

Niceone-tech customized membrane switches for different customers are widely used in various industries, empower exceptional product design for other man-machine interface solutions.

Membrane switch constantly updates and upgrades its technology, and its durability is gradually improved. Because of its superior performance and affordable price. As a reliable human-machine interface, it is increasingly favored by home, office and industrial applications.

Niceone-tech strictly customizes products in accordance with ISO9001-2015, and invests a lot of money every year to develop the technology of the membrane switch to improve the added value of products such as performance, life and function. Our membrane switches are exported in large quantities to European and American countries with stable quality and affordable prices. Niceone-tech understands the standards of European and American countries, so the products are always able to meet and exceed customer expectations.

What are the functions and advantages of membrane switches?

The reason why the membrane switch is widely used is because of some very superior performances. It can fulfill various requirements of users, from industrial equipment to medical equipment.

Moisture-proof performance: Because the membrane switch uses a good pressure-sensitive adhesive layer and the stable performance of Polyester, Lexan, Polycarbonate one of the materials together. Membrane switch can be designed to meet NEMA 4 and IP 67, some products can even reach IP68.

Thin: First, it is not easy to be invaded by dust, and secondly, it reduces the space of the product.

Easy to clean: Membrane switches are easier to clean the surface than other mechanical keyboards.

Cost-effective: Compared with touch keyboard and silicone rubber keyboard, membrane switch cost will be more affordable.

Graphic interface: The topmost panel of the membrane switch can be the most conventional screen printing or digital printing. Niceone-tech can design the product to achieve the best visual effect. At the same time display the company logo and key functions on the panel

Protection by design- through the design of membrane switches can achieve antibacterial, anti-ultraviolet and other effects.

Why use the membrane keypad made by Niceone-tech?

Niceone-tech can customize products that are perfect and best suited to customer requirements according to customer needs. In order to let you know how the best and most suitable membrane switch is produced, we must talk about its structure:

1. Overlay-Polyester is usually the first choice for membrane switch panel materials, because its life will be a little longer than Polycarbonate. If it is simply a panel instead of a membrane switch, Lexan and Polyester are also good choices. Overlay is the most intuitive form of human-machine interface. Niceone-tech will screen print or digital print on the back of the material, and they can also be used in combination. Special requirements such as mirror silver effect are also feasible.

2. Overlay adhesive-As the first layer of adhesive paper under the panel, Acrylic adhesive is usually used, generally the thickness is between 0.125-0.225mm. If it is LGF membrane switch (to LGF membrane switch) structure, the thickness sometimes reaches 0.64mm.

3. Top Circuit Layer (Dome retainer): This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as ESD shielding layer.

4. Circuit Spacer (switch spacer): Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch. If the upper circuit is only used as a fixed layer, then the general thickness of Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise the panel will squeeze the shrapnel to make the feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

5. Lower Circuit Layer: The thickness of this layer circuit is usually 0.1-0.188mm. It can be printed with ink, carbon oil and UV ink. LEDs can also be installed. Some membrane switch panels will choose copper flex or Printing circuit Board as the circuit. Compared with Polyester, their performance will be more stable. More often applied to the medical and military industries. If it is copper flex or Printing circuit Board as a line, Niceone-tech can even install a variety of components on the line.

6. Rear Adhesive: There are many choices, but the most commonly used are 3M200MP series or 3M300LSE. According to the different products of membrane switch lamination, Niceone-tech will recommend 3M300LSE if it needs higher viscosity.

7. Rigid Support Layer: This layer structure is generally used as the last layer of the membrane switch, which can make the structure of the membrane switch component more complete. Usually the choice of materials are AL, FR4, PC or steel. If AL is selected, nuts or feet may sometimes be added to the back of the product.

What special features can Niceone-tech membrane switches provide?

Backlighting Membrane Switch with Side-LEDs

Many working environments and machines will be used in low light or dark conditions. At this time, the customer asked us if we could solve this problem. At this time we will recommend the use of membrane switches with internal lighting. Choose EL film as the light guide plate, Fiber Optics, and the newer Light guide film (LGF) structure. Niceone-tech recommends LGF, which uses side LEDs and light guide panels to make the product have lower loss and longer life relative to EL membrane switch. Also available in different colors.

The thickness of the LGF membrane switch provided by Niceone-tech can even be 0.8mm. The brightness of buttons and logos is not only uniform and long-lasting, but more importantly, we can also make them illuminate each button individually. Sometimes you can also use two-color or RGB three-color lights to enter

One step makes the product more beautiful.

*If the customer wants the product to be more novel and beautiful, then we can sometimes use Epoxy in combination with the keys. Makes it an Epoxy LGF membrane switch

If you are interested in Backlit Membrane Switch, please feel free to contact Niceone-tech, we will send samples as soon as possible.

There are three other types of illuminating membrane switches below.

Fiber Optics

Fiber optic membrane switches are also a good choice for backlighting. The optical fiber material is very thin and can be used as a fixed layer of the membrane switch. At the same time, tactile feedback is better without adding a touch point. Life expectancy is up to 50,000 to 100,000 hours. The main light source is from LEDs

Through the optical fiber transmission in the membrane switch needs to light up. And can be larger than the surface-mounted LED backlight area. Click Fiber Optics membrane switch for more information.

Electroluminescent (EL)

EL backlight is driven by high frequency and low power. EL is very thin, it is a substitute for traditional lighting technology, and is widely used in various electronic accessories. The life of EL backlight products mainly depends on the driving voltage, frequency, temperature and humidity. But most EL membrane switches can reach a life of 4000 hours or more. The brightness of the EL membrane switch will attenuate linearly from the initial power-on. This is also an unavoidable disadvantage relative to other backlight membrane switch panels.

The EL backlit membrane switch provided by Niceone-tech will not cause heat, electricity and EMI problems. Mainly EL is more often a "cold" lighting medium.

LEDs

A common Light Emitting Diodes membrane switch with relatively low cost. Since this technology membrane switch cannot meet the lighting of a large area, it is mostly used for indication purposes. It is a relatively old technology. But the service life is long and deep customers love it.

Common design：

*Graphic overlays digitally and/or screen printed on the backside. The effect can be customized according to your requirements including glass, metal, wood, and stone. If the panel is in a more severe environment, we can even use hardened glass and stainless steel as the panel material. It is very important to choose Overlay printing according to requirements.

*The window needs raw materials to be transparent, frosted, transparent or colored. The window of the membrane switch is different, and the choice of materials is also very different. When the window is large, and it is required to clearly see the bottom LCD or touch screen. EBG series is a good choice, the material is scratch resistant. If it is just a panel, then PC or Lexan overlay is also feasible

*Selective textures and UV hard-coat surface finishes

*Tactile or non tactile, snap dome or non snap dome.

*Pillow rim-embossed membrane switch panels

*Optically clear adhesive(OCA)，Liquid Optically Clear Adhesive，Air Gap

*EMI/RFI shielding

*Rigid support backers such as aluminum and FR4 with PEM mounting fasteners

*Standard connectors such as CJT, Nicomatic and molex, etc.

Niceone-tech's custom-designed membrane switches and membrane switch keypads. Membrane switches are used in many industries. Niceone-tech summarizes several best membrane switch industries:

1. Medical Equipment and laboratories are the major markets. Niceone-tech provides customized membrane switches with complex requirements for many European and American manufacturers. In the medical environment, based on the standard membrane keypad, the materials sometimes have antibacterial effects and easy cleaning characteristics. At the same time Niceone-tech applies backlit and glue technology to the membrane switch. It can even be produced using digital printing.

2. Industrial Controls Because industrial equipment is more demanding moisture resistance and UV resistance, so the product's waterproof requirements and UV resistance performance requirements are relatively high. The choice of materials can refer to the membrane switch design guide, I believe that the materials compiled by Niceone-tech can help you.

3. Health & Fitness Equipment Because it is often corroded by sweat, salt and moisture, the material must be resistant to corrosion. Membrane switches are often used in treadmills. Using membrane switches to optimize performance and control is very important for fitness personnel.

What industry are you in?

What can Niceone-tech do?

Niceone-tech customized membrane switches are sold all over the world for different industries such as medical, industrial control, military, etc. Every contact with the membrane switch products will be convinced by its stability, touch, and beautiful appearance. For example, the membrane switch used outdoors for a long time, the product must have the ability to resist ultraviolet rays. In extreme environments, then the choice of materials also needs to choose a better 3M or Nitto adhesive, and the panel material Niceone-tech recommends Autotype. Making the appropriate design and materials according to the actual situation is one of the necessary conditions for a switch type membrane to satisfy customers.

Niceone-tech is a professional custom membrane switch manufacturer in China and believes in the professionalism of our team to customize a variety of membrane switches that satisfy customers.

Why Choose Niceone-tech Membrane Keypads?

Niceone-tech can customize membrane switch keypad that are perfect and best suited to customer requirements according to customer needs. In order to let you know how the best and most suitable touch keypad membrane is produced, we must talk about its structure:

Overlay-Polyester

is usually the first choice for membrane switch keypad materials, because its life will be a little longer than Polycarbonate. If it is simply a panel instead of a membrane switch keypad, Lexan and Polyester are also good choices. The overlay is the most intuitive form of human-machine interface. Niceone-tech will screen print or digital print on the back of the material, and they can also be used in combination. Special requirements such as mirror silver effect are also feasible.

Overlay adhesive

As the first layer of adhesive paper under the panel, the Acrylic adhesive is usually used, generally the thickness is between 0.125-0.225mm. If it is LGF membrane switch keypad structure, the thickness sometimes reaches 0.64mm.

Top Circuit Layer (Dome retainer)

This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil, and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as an ESD shielding layer.

Circuit Spacer (switch spacer)

Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch keypad. If the upper circuit is only used as a fixed layer, then the general thickness of the Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise, the panel will squeeze the shrapnel to make them feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

Lower Circuit Layer

The thickness of this layer circuit is usually 0.1-0.188mm. It can be printed with ink, carbon oil, and UV ink. LEDs can also be installed. Some membrane switch keypads will choose the copper flex or Printing circuit Board as the circuit. Compared with Polyester, their performance will be more stable. More often applied to the medical and military industries. If it is copper flex or Printing circuit Board as a line, Niceone-tech can even install a variety of components on the line.

Rear Adhesive

There are many choices, but the most commonly used are 3M200MP series or 3M300LSE. According to the different products of membrane switch lamination, Niceone-tech will recommend 3M300LSE if it needs higher viscosity.

Rigid Support Layer

This layer structure is generally used as the last layer of the membrane switch keypad, which can make the structure of the membrane switch keypad component more complete. Usually, the choice of materials is AL, FR4, PC, or steel. If AL is selected, nuts or feet may sometimes be added to the back of the product.

What Special Features Can Niceone-tech Membrane Switches Provide?

Backlighting Membrane Switch （LGF）

Many working environments and machines will be used in low light or dark conditions. At this time, the customer asked us if we could solve this problem. At this time we will recommend the use of membrane switch keypads with internal lighting. Choose EL film as the light guide plate, Fiber Optics, and the newer light guide film (LGF) structure. Niceone-tech recommends LGF, which uses side LEDs and light guide panels to make the product have a lower loss and longer life relative to the EL membrane switch. Also available in different colors.

The thickness of the LGF membrane switch keypad provided by Niceone-tech can even be 0.8mm. The brightness of buttons and logos is not only uniform and long-lasting but more importantly, we can also make them illuminate each button individually. Sometimes you can also use two-color or RGB three-color lights to enter.

One step makes the product more beautiful.

*If the customer wants the product to be more novel and beautiful, then we can sometimes use Epoxy in combination with the keys. Makes it an Epoxy LGF membrane switch

If you are interested in Backlit Membrane Switch, please feel free to contact Niceone-tech, we will send samples as soon as possible.

There are three other types of illuminating membrane switches below.

Fiber Optics

Fiber optic membrane switch keypads are also a good choice for backlighting. The optical fiber material is very thin and can be used as a fixed layer of the membrane switch. At the same time, tactile feedback is better without adding a touchpoint. Life expectancy is up to 50,000 to 100,000 hours. The main light source is from LEDs.Through the optical fiber transmission in the membrane switch keypad needs to light up. And can be larger than the surface-mounted LED backlight area. Click the fiber optics membrane switch for more information.

Electroluminescent (EL)

EL backlight is driven by high frequency and low power. EL is very thin, it is a substitute for traditional lighting technology, and is widely used in various electronic accessories. The life of EL backlight products mainly depends on the driving voltage, frequency, temperature, and humidity. But most EL membrane switches can reach a life of 4000 hours or more. The brightness of the EL membrane switch keypad will attenuate linearly from the initial power-on. This is also an unavoidable disadvantage relative to other backlight membrane switch keypads. The EL backlit membrane switch keypad provided by Niceone-tech will not cause heat, electricity, and EMI problems. Mainly EL is more often a "cold" lighting medium.

LEDs

A common Light Emitting Diodes membrane switch keypad with relatively low cost. Since this technology membrane switch keypad cannot meet the lighting of a large area, it is mostly used for indication purposes. It is relatively old technology. But the service life is long and deep customers love it.

Custom Membrane Keypad Design

Graphic overlays digitally and/or screen printed on the backside. The effect can be customized according to your requirements including glass, metal, wood, and stone. If the keypad is in a more severe environment, we can even use hardened glass and stainless steel as the keypad material. It is very important to choose Overlay printing according to requirements.

The window needs raw materials to be transparent, frosted, transparent, or colored. The window of the membrane switch is different, and the choice of materials is also very different. When the window is large, and it is required to clearly see the bottom LCD or touch screen. EBG series is a good choice, the material is scratch resistant. If it is just a keypad, then PC or Lexan overlay is also feasible.

Selective textures and UV hard-coat surface finishes

Tactile or non-tactile, snap dome, or non-snap dome.

Pillow rim-embossed membrane switch keypads

Optically clear adhesive (OCA)，Liquid Optically Clear Adhesive，Air Gap

EMI/RFI shielding

Rigid support backers such as aluminum and FR4 with PEM mounting fasteners

Standard connectors such as CJT, Nicomatic, and Molex, etc

Graphic Overlays

The structure of the Graphic overlay or control panel overlay is very simple. It is a single-layer structure of polycarbonate or polyester or an interface layer composed of adhesive. Graphic overlay uses are generally divided into two types: one is as a decorative Graphic overlay, so the product is more focused on whether to convey information such as the operation of the device, the company's logo, and product information. The second is the functional custom Graphic overlay, the product is more used for the circuit layer or the combination of silicone, and sometimes even combined with the shrapnel to form the shrapnel layer. Since Graphic overlay is the top-level structure of the product, it must be aesthetically pleasing and impressive. Niceone-tech not only pursues the beauty of the product but also the high performance of the product.

Graphic Overlays

Niceone-tech's Design Suggestion for Graphic Overlays

According to the application method of membrane overlay, Niceone-tech's most professional design suggestions are given. Here are some suggestions from Niceone-tech for Graphic overlay materials:

Whether the product is used outdoors or indoors, if it is used outdoors, the external factors that affect the life of the product, such as ultraviolet light, temperature, humidity, and dust, must be considered for the panel and adhesive tape materials. If Graphic Overlay is to be used outdoors for long periods of time and extreme high and low-temperature use, Niceone-tech panel recommends the Autotex material of XE series or HP92W, etc., and Niceone-tech adhesive tape recommends 3M. For indoor use, Niceone-tech can provide different options according to the customer's budget. The most common design for products without windows is Autotex F150 or V150 + 3M adhesive. With windows, Niceone-tech recommends using EBG + 3M adhesive paper. But Niceone-tech will respect the customer's decision, we will only give our professional advice for customers to choose from.

The choice of Graphic overlay material can be polycarbonate or polyester, whichever has its unique properties. From the perspective of the number of driving times, Niceone-tech will recommend Polyester material because it can be pressed repeatedly millions of times without breaking. The PC material can't meet this requirement relatively. Conversely, if customers only need an indicator panel and the cost is lower, Polycarbonate is a good choice.

Graphic overlay needs to be resistant to bacteria or anti-microbial, and the chemical properties are required to be stable. The AM series of Autotex materials is a good choice.

The feel of the control panel is sometimes one of the conditions considered. Materials include Velvet, Gloss, Matte, and another different touch, Autotex of F, V, and XE series is Velvet, Autotex of EBG series, HP92W and FR-60 Lexan is Gloss. Matte touch is EBA and HP-40Lexan as options.

If you want to know what material is most suitable for your Graphic panel product, and want to customize a polycarbonate overlay or polyester overlay suitable for you, please contact [email protected]. If you need to customize graphic overlay, Niceone-tech will Produce drawings within 3 days, send graphic overlay prototype within 15 days.

Aesthetic Considerations Affecting Graphic Overlay Design:

Graphic overlay printing: Graphic overlay has Screen printing and digital printing. Screen printing colors generally have small errors, but the colors are not Fades or Gradients. Digital printing can be Fades or Gradients, but the color error is large.

Does Graphic overlay need to be embossed: embossed is generally divided into Rim Embossed, Pillow Embossed, and Dome Embossed. The logo or letters of the product also need to be convex, Niceone-tech will analyze whether it can be generated. At the same time, some products also need to hit blind spots.

The surface treatment of Graphic overlay includes 1. Glossy 2. Non-glare 3. Textured 4. Patterned 5. Metals (e.g. brushed aluminum, stainless steel)

The graphic overlay has an LCD window and an LED window. The window selection of LED is generally transparent white or transparent raw materials. LCD's windows are produced according to customer requirements. Generally speaking, the raw materials are transparent or silkscreen transparent colors, and the windows are also required to be scratch-resistant. If you want custom graphic overlay, you can contact Niceone-tech, as a graphic overlay manufacturer, our professional and timely feedback will definitely make you gain something.
