Excellent quality Computer Sewing Machine Membrane Switch - FPC membrane switch – Xinhui Detail:
FPC membrane switch
FPC membrane switch means that the graphics and circuits of the switch are made on a common printed flexible copper clad laminate.
FPC membrane switches are characterized by convenient materials, stable process, low resistance, and some components in the circuit can be directly welded on the back of the FPC membrane switch. FPC membrane switches generally use metal guides as the conduction labyrinth contacts, so they have a better feel.
Advantages: The minimum wire distance can be 0.5MM, the resistance value is extremely low, and small components such as LEDs, resistors, and optical fibers can be welded. The performance is reliable and the life is long. The failure rate is 99.8%. It is a non-ordinary silver paste-based flexible membrane switch. Can go hand in hand.
Disadvantages: The FPC cost is relatively high, and the pricing is based on the longest and widest area. Therefore, it is necessary to reduce the length and irregular shape of the lead as much as possible in the design to avoid unnecessary waste and increase unnecessary costs.
Recommendation: Users who need to assemble LEDs, resistors, optical fibers and ultra-precision components should choose FPC membrane switches.
