Electrolytic polishing
Electrolytic polishing is a process in which, through an electrolyte, metal is removed from a work piece through electrolysis. It uses the effect that, on the microscopic level, material of elevations is removed faster than material found in depressions. The result is a smooth, mirroring surface. In the field of electronic manufacturing, this process is applied to polish printing stencils. With the reduction of the surface roughness, the releasing behavior of the solder paste is improved.
