On the copper foil that needs to be preserved on the outer layer of the circuit board, the circuit pattern is pre-plated with a lead-tin anti-corrosion layer. Then, the unprotected non-conductor part of the copper is chemically etched to form a circuit.
According to the different process methods, etching is divided into inner and outer layer etching. The inner layer etching adopts acid etching, using wet film or dry film as the resist. The outer layer etching adopts alkaline etching, using tin lead as the resist.
1. PCB fabrication.
2. Turnkey PCBA: PCB+components sourcing+SMD and through-hole assembly
3. PCB clone, PCB reverse engineering.
