【 Weak current College 】 General performance of flexible circuit boards and parameter 】

Flex circuit is to polyimide or polyester film as the substrate made of a high reliability, excellent to flexible printed circuit, this circuit can be bent, folded, winding, can move in three dimensions and its expansion, thermal performance, reduce the volume can be used to achieve the FPC lightweight, compact, thin, so as to achieve the component unit and conductor connect integration.
