Technical 丨 PCB circuit board common reasons for copper wire off

In the PCB manufacturing process,we will often encounter  some common process defects,such as poor copper wire
on the PCB circuit board (also known as PCB copper falling off),  which affects product quality. There are several common reasons for copper falling off on PCB
However, the PCB circuit board Process Capability  factors:
1. Copper foil is excessively etched. The electrolytic copper foil used on the market is generally unilateral galvanized (commonly known as ash foil) and single-sided copper plating (commonly known as red foil).
