Dome Sheets & PCB

1. Introduction to Dome Sheets & PCB

Dome Sheets and PCB are crucial to solutions that directly attach metal domes to a printed circuit board (PCB) or a flexible printed circuit board (FPC).

In this design, the dome sheets have a distinctively felt feelable surface and a conductivity that is electrical. The PCB facilitates the transmission of signals and the creation of circuits. This combined design diminishes the number of components and increases the efficiency of assembly.

SHANYO Precision Electronics employs precise die cutting and high-precision attachment methods to ensure precise placement and consistent conductivity of the domes on the PCB, which satisfies the operational requirements of various electronic control devices.
