<p>Flexible Printed Circuit Board referred to as "<a href="https://www.atech<a href="https://www.atechpcb.com/flexible-pcb" target="_blank">pcb</a>.com/<a href="https://www.atechpcb.com/flexible-pcb" target="_blank">flexible</a>-pcb" rel="noopener noreferrer" target="_blank">flexible</a> board", commonly known as FPC in the industry, is a printed circuit board made of flexible insulating substrate (mainly polyimide or polyester film), with many rigid printed Circuit boards do not have advantages. For example, it can be bent, wound and folded freely. The use of FPC can greatly reduce the volume of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras and other fields or products.</p><p>FPC also has the advantages of good heat dissipation and solderability, easy gathering and low overall cost.</p><p><a href="https://www.atechpcb.com/flexible-pcb" rel="noopener noreferrer" target="_blank">Flexible printed circuit boards</a> are divided into single-sided, double-sided and multilayer boards. The base material used is mainly polyimide copper clad laminate. This material has high heat resistance, good dimensional stability, and a cover film that combines mechanical protection and good electrical insulation properties to form the final product by pressing. The surface and inner conductors of double-sided, multi-layer printed circuit boards are metalized to achieve electrical connection between the inner and outer circuits.</p><p>The functions of the flexible circuit board can be divided into four types, namely Lead Line, Printed Circuit, Connector, and Integration of Function, which covers computers and computer peripherals.
