Pcb metal mask thickness

SpletThe tolerance for mask placement is ±2mils so that is why we adjust mask apertures to be 2mils larger all the way around the copper feature helping to ensure the entire pad can be soldered. There are times when a mask defined pad is required. A mask defined pad is when the mask relief is the same size or smaller than the copper pad it is exposing. SpletThe typical PCB thickness is 0.063inches or 1.57mm; it is a standardized level defined from the past. That is because, during the plywood industry, 0.063" was the thickness of the …
