Flex – LUCKPCB

Flex PCB

Flex PCBs are flexible and can be bent and folded to fit complex device designs. By using polyimide or polyester film as a substrate, Flex PCBs enhance heat resistance and reliability. At Flex PCB manufacturers like Zotek, multi-layer Flex PCBs can be produced with designs of up to 24 layers
