Surface finish (also sometimes called surface roughness) is a numerical representation of the "smoothness" of a surface. There are three main ways to get the surface roughness value: 1. Mechanical scanning: The most common method is to scan the surface with a needle that records miniature "hil...
PCB surface finish is implemented on the board on solderable areas to enhance good inter-metallic bonding and increase the board shelf-life.
a large amount of foam is generated due to the dissolution of a large amount of organic film materials, and the air is mixed in during the extraction and spraying action, which is very inconvenient for the process. It is necessary to add chemicals to reduce surface tension in the bath, su...
