4 Layer Rigid-Flex PCB

By being able to design in three dimensions rigid flex designers can twist, fold and roll the flexible board substrates to achieve their desired shape for the final application's package.storm circuit fabicate many  complex rigid-flex pcbs,especially 4 layer rigid-flex pcb is very simple to us.
