NOT KNOWN FACTS ABOUT EIGHT-LAYER FIRST-ORDER RIGID-FLEX PCB

Idea: Just about every copper layer is assumed to provide the similar completed copper fat Unless of course or else laid out in your fabrication notes. A 4-layer board with a defined pounds of 1oz, is assumed to have a finished copper thickness of 1.37mils (or more) on each individual copper layer.To use circuits on either side, there needs to
