CONSIDERATIONS TO KNOW ABOUT 6-LAYER ONE-STAGE LED SMALL-PITCH DISPLAY PCB BOARD

Electroplated nickel gold is more usually applied on IC substrates (like PBGA), generally for binding gold wires and copper wires; but when electroplating C substrates, additional conductive wires should be built for the gold finger binding position right before electroplating.A lot of components of double-sided Printed Circuit Board layouts are
