FPCs are generally installed bent, folded or twisted, and are primarily used to replace wiring, connectors and antennas, then gradually to be the Flex-rigid PCBs aminated with rigid PCBs, now in widely use throughout the electronics industry. In response to market requirements, LYB becomes a prototype-to-production Flex and rigid-flex PCB supplier. With its growing stronger core HDI technology in combination with flexible printed circuit boards, LYB also provides high density interconnect (HDI) Rigid-flex PCBs.
