Autotype F150 Metal Dome FPC Membrane Switch

Product Overview

Description

Autotype F150 Metal Dome FPC Membrane Switch  

 

Flexible circuit board (FPC) is made of a kind of laminated material that has insulation to resist heat, electrical properties, metal foil, and adhesive. Usually, conductive bumps allow conductivity between the flexible circuit board and another circuit board by pressing the bumps to pads with pressure. This creates electric flow between the systems. Flexible circuit boards are known for their lightness, thinness, flexibility, and convenience in size.

When should we use FPC as membrane switch’s circuit?

Sometimes, the membrane switch size is small, but there are many buttons and LEDs, then by the single PET circuit layer couldn’t place so many components, then can consider to use double sided FPC as the circuit layer. By the way, the FPC circuit cost is higher than PET circuit, but it also has its advantages, for example, the FPC is more stable, tough. Especially when should assemble many LEDs on the circuit, then use FPC, the quality and stability will be much better then PET circuit. Of course, this depends on customer’s requirements and decisions. If the customer no requirements, then we suggest use FPC as circuit only when it couldn’t fulfill customer’s function by PET circuit.
