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.
