A tactile membrane switch embeds a metal dome or a poly dome within the switch assembly to produce the appropriate tactile response. These domes can be made of conductive materials and sizes, which allows you to alter the actuation force, when turning on the switch. A second adhesive layer known as the dome retainer is applied beneath the graphic overlay to hold the crown in place.
What kind of PCB assemblies we can do?
For PCB printed circuit board, it is conventional rigid PCB. That means the electric circuit layer will be embed by temperature,while coating with insulation printing, complete a basic electric circuit on substrate. Another one, some of required electric parts ,such as diodes, audions , capacitances,risistances,some of integrated chips even led chip,fixed on it. Like this, the mainboard will become an integrated control module unit. Added with burned running programme, it will become more and more automation and intelligent !
Sometimes ,such control module unit can work with membrane switch together, become User interface, so that offer more convenience and security to the end users better. By operating membrane switch, will control a big size machine to do some intelligent works, this will be our contributions for machinical and industry field,

We print the capacitive touch buttons/sensors on the PET circuit with transparent conductive ink. We also use ITO etching technology to make the capacitive touch buttons/sensors.
Through the customized IC chip to control the touch function wanted. Except for the capacitive touch keypads we also manufacture the capacitive touch sensor circuits.
With capacitive touch technology, the overlay materials can be very diverse and not only limited to PET or PC super thin films. For the normal membrane keypads, the function is triggered by the mechanical buttons(metal domes or Polydome), and also the common membrane keypads only can use PET or PC film for the graphic overlay.
Use a heavy force to press the buttons to make the conductive pads of the Polydome or metal domes connected to the conductive pads on the circuit layer, then become a loop circuit and occur the function. But for the capacitive touch membrane keypads or circuits, it is different.
We use a variety of overlay materials such as thick glass, PMMA, Polycarbonate panels, etc. The material choice is no longer limited to only a very thin film material, on the contrary, the options are not endless.
In addition, the capacitive touch keypad no longer needs heavy force to press buttons, you only need tiny touch the buttons, then the sensor pad can connect the circuit loop and occur the function.
Sealing against heat
Especially in food packaging industry, this film can resist moisture for longer periods of time than any other possible film. These films can also resist high temperatures and extreme pressures. Some of the chemicals that OCA is usually used for are water-soluble adhesives, solvents, oils and acrylics. OCA is mostly used for bonding and sealing purposes.
Long shelf life
When using OCA you donâ??t have to worry about changing your adhesive films frequently. You can easily use them for many years together without having to worry about their effectiveness. This property of OCA is used all over the world in several sectors. From automotive and construction to food packaging and medical devices industries, you name it and you have it!
Better adhesive bond
Itâ??s all about better bond especially when we talk about products with high friction and usage level. The OCA is very easy to use and has better adhesion properties. The film can also withstand extreme temperature variation, can handle pressure and is able to maintain its quality for a long time.
No post flow problems
It has no post flow limitations. It can be easily applied even on curved surfaces. It can also work well with polyethylene and vinyl and other related materials. Itâ??s clear that OCA doesnâ??t have any restriction for applying it on different objects.
Better adhesive adhesion
There are more than hundred unique OCA bonding agents which make it better than other possible adhesive media available in the market. Itâ??s also more durable than other known adhesive. It can resist heat, abrasion and chemical treatments. Its anti-stagnant quality allows the document to be used in any environment. Its anti-reflective property makes it work well with light and fluorescent.
UV stabilization
It also has the UV stabilization feature. It works well to safeguard documents from harmful ultraviolet rays. So, it will not be affected by UV rays. It can work with any type of document.
Vibrant and bright white
OCA is extensively used for signage and also used as labels in food products like dairy products, milk and juice, etc. They are applied in outdoor and indoor environments as well. The vibrant and bright white color make it easy to recognize and read. It has excellent scratch resistance. It is water, heat and moisture resistant as well. The fact that it can be applied on smooth and flat surfaces makes it popular for use in food packaging and household items.
