7. The design of PCB（multiple layer board)-- Process of multilayer board
Multiple Layer Board Juvtmall ( a company supply PCB Prototyping, PCBA service and sell kinds of components, modules and so on)
PCB Multilayer Board means multilayer board used in electrical product, it involves wild area, such as home appliance, computer accessories, communication, toy, instrument, LED and so on. PCB(printed circuit board) Multilayer Board is consist of track on several layer of insulation substrate and pad, it has two function: conduct every layer’s circuit, insult mutual layer. As the develop of SMT, the launch of new SMD (such as QFP, QFN, CSP, BGA), electrical product become more intelligent and smaller. Since HDI is created, the develop these process technology lead the design of PCB to multiple layer, and high density.
1. Process of multilayer board 1. PCB which has draw the track: Put on the board, acidity deoiling, scanning rinsing, second reflux rinsing, micro etch, scanning rinsing, second reflux rinsing, presoak copper plating, copper plating, scanning rins…
