PCB knowledge: Process of Multilayer PCB

A) In general, a multilayer board consists of a number of very thin print-and-etch inner layers, but drilling of holes has not been carried out. Outer layers of the multilayer board remain unetched.

B) Layers from top to bottom are bonded together in close registration by means of thin plies of prepreg. The bonding is performed under close temperature and pressure control in a lamination press.

C) After lamination, they are the processed in very much the same way as an ordinary double-sided PTH boards, i.e. holes are drilled, cleaned and plated. Outer layers are etched to develop the circuit pattern. Solder masks are applied and solder coating (HAS, ENIG etc) is performed.

FAQ

How do you pack the PCBs?
PCBs are packed with Polyethylene air cushion film(vacuum plastic bags) per 20-25 pieces. Pearl cotton (Polyethylene foamed sheet) are put inside carton box.
The hardness of carton box is KK grade(the highest hardness). Maximum gross weight for one carton is less than 12 kgs.
