Flexible PCB manufacturing Process

Drilling – Drilling can make the inner layer and outer layer be electrical connected.

Copper Plating – Copper plating over the drilled vias to permit the connection between layers.

Pattern – Double face coating-Exposure-Developing-Etching-Stripping-Printing circuits on the substrate

Solder Mask – Protecting the PCB circuits by using Coverlay, PSR ink.

Surface finishing – Anti-oxidation process (OSP, Immersion gold) and good for soldering

Attach reinforcement and inspection – Attach PI, FR4, Steel reinforcement to promote durable and quality inspection

Package – loose in bag or in panel packing (lie papers between each piece and protect by using gusset plate on top and bottom)

Shipping – DHL, TNT, FedEx, By air or by Sea.
