5 SIMPLE STATEMENTS ABOUT 16-LAYER 3-LEVEL HDI PCB EXPLAINED

Electroplated nickel gold is much more normally used on IC substrates (including PBGA), generally for binding gold wires and copper wires; but when electroplating C substrates, additional conductive wires need to be created for the gold finger binding place just before electroplating.The metal layers on the multilayer PCB will conduct the electr
