High Temperature Resistant Large Digital FFC Board
$7.80 – $22.00 / pc · MOQ 500 pcs
A high-temperature, large-format digital FFC and membrane-switch circuit board: -40 to +80 °C operation, up to 500 million flat-type operations.
- Description
A large digital FFC and membrane-switch circuit board for equipment that runs hot or has to survive temperature swings. It is a planar multilayer assembly that brings the key function, the indicating element and the panel together in one sealed, integrated component.
The membrane-switch construction replaces discrete keys with a printed circuit, so it can be built on either a rigid or a flexible board, with tactile or non-tactile buttons and a printed overlay. The circuit connects to the machine by splicing or welding.

One thing to know about the figures: the factory sheet for this item carries the membrane-switch parameter set — the manufacturing process behind the assembly — rather than cable-only dimensions. The values above describe the board as supplied. If your design needs a specific trace width, pitch or pinout, tell us and we will build to it.
Custom and OEM options
Connector type, cable length, jacket colour, printed logo and retail packaging with your own artwork can all be specified. Standard items from 100 pcs, custom builds from 500 pcs, free samples, production in 20–25 working days.
