Flexible Printed Circuit (FPC), also known as flex PCB, are electronic circuit boards made of flexible substrates (such as polyester film). Compared to traditional rigid printed circuit boards (PCBs), FPCs are characterized by their flexibility, lightweight, and ability to bend, allowing for flexible arrangement of electronic components in limited spaces.
