How do Flexible PCB manufacturer fabricate FPC?
FlexiblePCBmanufacturer learned that，a flexible PCB, abbreviated for FPC, is a polyimide (PI) or polyester (PET) based printed circuit board that can bend and fold.Flexible PCBs can be single-sided, double-sided, yellow, black, white, and transparent.They are light, and thin, and are widely used for applications where flexibility is required.
