You probably don’t give much thought to how your device’s keypad is made and assembled, but it’s a pretty cool process. We know because we go through the silicone keypad assembly process every single day.

SiTech’s assembly process is not only efficient and cost effective, it’s also easy to implement and customize when it comes to shapes, surface finishes and more.

You can actually customize your keypad with any of the following, all of which reduce time in managing sub-assemblies incorporated in keypad assembly:

• Membrane circuit
• Printed circuit board
• Metal domes
• Polyester domes

The keypad assembly begins with the initial design phase and ends up at the turnkey solution.

Industries Served

If you’re looking to manufacture a complete keypad assembly but aren’t sure how to go about it, that’s what we’re here for. In fact, we get many requests from customers in a multitude of industries to use our proven factory capabilities to meet their needs. Over the years, we have built up a reputation for meeting the keypad assembly needs of all industries, from aerospace and medical to telecommunications and automotive.

We have the capability to design the right keypad for your needs using quality silicone materials. The one you go with will depend on your industry and specific device needs. Perhaps you want a Printed Circuit Board Order or maybe you want a flat membrane switch. Whatever the case, we can create it based on intended usage, requirements, schematics and material needs.

Here is how the silicone keypad you see on your devices is assembled.

1.    You Select the Design

First, you have a variety of choices when it comes to what you want your keypad to look like. Thanks to our Silastikey™ design options, you can select from the following. Of course, we can help you in this process!

• Key Travel/Actuation Forces
• Quality Graphics/Colors
• Back Lighting
• Custom Shapes
• Clear Windows
• One-Piece Construction
• Custom Surface Finishes
• Sealing Features and Wrap-Around Designs
• Light Pipes
• Abrasion Resistance Barriers
• Proprietary Chemical Barriers
• SiPrime ™ Adhesive Primer System (adhesive bonding and laminating)

2.    You Select the Core Elements

Next, it’s time to select the core elements of the overall design. Again, we can help you decide on the following:

• Type of Termination (Ribbon, Connector, Header, Flat Flex Cable)
• Type of board plating (Gold Plating, Matte Tin Plate, HASL, Nickel)
• Single/Double-sided or Multi-layer boards (varied by industry)
• Type of dome (metal or polyester), contributes to desired tactile response
• Mechanical vs. tack switch (PCB mounted vs. auto insertion)
• Fully-Operational PCB Assembly (includes intelligence for intuitive design)
• Half Switch Assembly (rubber keypad w/ tactile switch layer only)
• Operational PCBs (switch layout only)
