YouMi Flex Membrane Switches AND PET circuit Membrane Switches

YouMi Flex Membrane Switches AND PET circuit Membrane Switches For the flex circuit membrane switches, there are two types. They are silver printed PET circuit and copper etched FPC circuit. Their difference and advantages&disadvantages listed bellow:YouMi Flex Membrane Switches AND PET circuit Membrane Switches: Items Silver Printed Circuit Copper Etched FPC Circuit Material PET (Polyester) Copper Conductor Printed silver Copper Contact Fingers Silver and Carbon Gold plated Contact Buttons Pads Silver Gold plated Life & Reliability normal good Stability normal good Resistance low Very low Cost low high Lead Time 2-3 days 7-10 days Pitch 0.5mm (not suggested), 1.0mm,1.27mm,2.54mm 0.5mm, 1.0mm,1.27mm,2.54mm Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical. In addition if the conductor pitc
