How to Solve PCB Plating Film Issues?
With the rapid development of the PCB industry, PCBs are gradually moving towards high-precision fine lines, small apertures, and high aspect ratios (6:1-10:1). The copper requirement for holes is 20-25μm, and for boards with DF line spacing ≤4 mil, most PCB manufacturers face plating film issues. Film entrapment can cause direct short circuits, affecting the … Read more
