Flexible Printed Circuit Boards

FPC (Flexible Circuit Board) is a type of PCB, also known as a "soft board". FPC is made of flexible substrates such as polyimide or polyester film, which has the advantages of high wiring density, light weight, thin thickness, flexibility, and high flexibility. It can withstand millions of dynamic bends without damaging the wires, and can move and expand according to spatial layout requirements to achieve three-dimensional assembly, achieving the integration of component assembly and wire connection. It has advantages that other types of circuit boards cannot compare.

FPC is widely used in mechanical sensitive devices because its flexibility allows circuit boards to resist vibration. Flexible PCBs are more durable than traditional circuit boards, but their manufacturing process is sensitive and complex.

    Flexible PCB Applications

    Rigid plates have added some limitations in product design as they cannot be installed in limited spaces. Circuit boards need to have vibration resistance in products that are often subjected to mechanical impact.
    Flexible PCBs are more suitable for this situation as they can be bent and wrapped if needed. They can survive in harsh temperatures ranging from -200 to 400 degrees Celsius. Compared to traditional circuit boards, these functions make flexible circuit boards more reliable and durable.

    Technology highlights

    Mainly polyimide materials, flex PCB’s are necessary when motion of the PCB is needed, when 3-D interconnections are necessary (i.e. replacing cables and connectors) or when these are both combined due to limited available space.
