SpletAs one of the last working steps in the PCB manufacturing, the bare copper on the PCB is coated with a surface finish. The surface finish protects the underlying copper against oxidation and therefore increases storability. In addition, the surface finish is responsible for raising the wetting ability of the contact areas for soldering. SpletThis is because the HAL process creates the surface of the circuit board with a tin bath. The fluid tin forms "drops" on the surface areas and runs along the edged of holes and pads. This causes the surface of the circuit board to be very thin right at the edges, and may lead to solder problems. A uniform surface thickness can generally not be ...
