Flexible (Flex) PCBs



2L Flex – materials: Shengyi SF-305; surface treatement:ENIG

FeatureTechnical Specification
Number of layers 1 – 6 layers
Technology highlightsMainly polyimide materials, flex PCB’s are necessary when motion of the PCB is needed, when 3D interconnections are necessary (i.e. replacing cables and connectors) or when these are both combined due to limited available space.
