The basic manufacturing craft process of the pcb prototype Double-sided circuit is as follows:

Graphic plating craft process

Foil–>Unloading–>Drilling Datum Hole–>CNC Drilling–>Inspection–>Deburring–>Chemical Plating Copper–>Electroplating Thin Copper–>Inspection–> Brush plate –> film (or screen printing) –> exposure development (or curing) –> Inspection and repair board —> pattern plating (Cn ten Sn / Pb) –> remove film –> etching – ->Inspection and repair board–>Plug nickel plating gold plating–>Hot melt cleaning–>Electrical continuity test–>Cleaning treatment–>Screen printing resistance pattern–>Cure–>Screen printing symbol- -> Curing -> Shape Processing -> Cleaning and Drying -> Inspection -> Packaging -> Finished Product.


The main advantage of the bare copper solder mask (SMOBC) process is to solve the solder bridging short circuit between the thin lines, and because of the constant lead-tin ratio, it has better solderability and storage than the hot melt board. The SMOBC process for replating lead-tin by pattern plating is similar to the pattern plating process. Change only after etching. Double-sided pcb copper clad plate–> according to the pattern plating process to the etching process–> lead-free tin–> check—->clean—> solder resist pattern–> plug nickel-plated gold–> Plug tape -> hot air leveling —-> cleaning —> screen printing symbol —> shape processing —> cleaning and drying —> finished product inspection –> packaging –> finished products.
