We often see the PCB, but few know that in how produced. Even if the operator of the mill is also difficult to know all the whole production process steps. Here is information access to numerous data after finishing.
Typical process of manufacturing the printed circuit board:
Single panel:
Sided cover material under the copper plate → → grinding plate printed the corrosion graphics → curing → ​​drying → Network → Etching → to film → drying → grinding plate → drying → Screen Printing solder graphics → curing → ​​Screen Printing characters → curing → network printed on the reverse side characters → curing → ​​preheat → → drilling die red positioning hole punching, shape processing → ​​electrical performance test → washing → ​​drying → precoating flux → drying → ​​inspection → packing → finished
Dual-panel (graphics, electroplating, etching):
CNC drilling → ​​test → deburring grinding plate → electroless copper → → thin copper plating → ​​test → grinding plate → film or screen printing wet film → exposure → developing → ​​test → graphics double-sided copper clad board → cutting → grinding board of inspection and repair the board of inspection and repair panels of plating (Cu, Sn / Pn, Ni / Au) → Stripping → ​​→ etching → ​​→ → Screen Printing solder → baking → ​​exposure → printed characters of developing → ​​network → → surface of the baking sheet processing (HAL) → shape processing → ​​washing drying → ​​Test → → product packaging
Ordinary multilayer
Core cover grinding plate → inner graphics production material under the copper plate → → → Etching → ​​test → brown → Lamination → drilling → ​​electroplating a thin copper plate mill → electroless copper → → test → grinding plate → film screen printing wet film → exposure → developing → ​​test → Pattern Plating (Cu, inspection and repair board of repair board of Sn / Pn, Ni / Au) → Stripping → ​​test → etching → ​​→ grinding plate → Screen Printing solder → baking → ​​exposure (HAL) → shape → developing → ​​Screen Printing characters → baking sheet → surface treatment process → cleaning drying → test → Packaging → finished
     Seen from the above process, a circuit board from the file to the cost, is a complex process, many labor and machinery and equipment, the brainchild of any one product is a lot of people.
