PCB production process

For example: 1) single panel process

Cutting edging → drilling → outer layer pattern → (full plate gold plating) → etching → inspection → silk screen resistance welding → (hot air leveling) → silk screen characters → shape processing → test → inspection

2) Double-panel tinplate process

Cutting edging → drilling → thickening of copper ● outer layer pattern → tin plating, etching tin removal → secondary drilling → inspection → silk screen resistance welding → gold plating plug → hot air leveling → silk screen characters → shape processing → test → Inspection

3) Double-panel nickel-plated gold process

Cutting edge grinding → drilling → thickening of copper ● outer layer pattern → nickel plating, gold film etching → secondary drilling → inspection → silk screen soldering → silk screen characters → shape processing → test → inspection

4) Multi-layer board tin plate process

Cutting edge grinding→Drilling positioning hole→Inner layer pattern→Inner layer etching→Inspection→Blackening→Lamination→Drilling→Pinking thickening→Outer pattern→ Tin plating, etching tinning→Secondary drilling→Inspection →Silk screen soldering→gold-plated plug→hot air leveling→screen printing characters→shape processing→test→test

5) Multi-layer plate nickel-plated gold process

Cutting edge grinding→Drilling positioning hole→Inner layer pattern→Inner layer etching→Inspection→Blackening→Lamination→Drilling→Pinking thickening→Outer pattern→Gold plating, film removal etching→Secondary drilling→Inspection→ Screen printing solder mask → silk screen characters → shape processing → test → inspection

6) Multi-layer plate nickel-plated gold plate process

Cutting edge grinding→Drilling positioning hole→Inner layer pattern→Inner layer etching→Inspection→Blackening→Lamination→Drilling→Pinking thickening→Outer pattern→ Tin plating, etching tinning→Secondary drilling→Inspection →Silk screen soldering→Chemical nickel-plated gold→Screen printing characters→Shaping processing→Test→Inspection
