Multi-layer Flexble PCB uses single-sided FCCL and adhesive as the base materials, the similar technology of Double-sided FPC with the method of single side, double access; through several times of la…
After the double-sided PI board copper-clad board material is used in the double-sided circuit, a protective film is added on both sides to form a circuit board having a double-layer conductor. The St…
After the completion of the circuit, the single-sided PI-clad material is covered with a protective film to form a flexible fpc with only a single layer of conductor. Structure of Single-layer FPC The…
