How many types of flexible circuit boards are there?
How many types of flexible circuit boards are there? At present, flexible circuits mainly have four types of single-sided FPC, double-sided FPC, multi-layer FPC and rigid flexible circuit boards. 1. Single-sided flexible PCB Single-sided flexible board is the lowest cost, when the board is not required for high electrical performance. For single-sided wiring, a single-sided flexible board should be used. It has a chemically etched conductive pattern, and the conductive pattern layer on the surface of the flexible insulating substrate is a [...]
