SM - Soldermask - Eurocircuits

Soldermask is a protective layer of liquid photo image able lacquer applied on the TOP and BOTTOM side of a Printed Circuit Board. The function of the Soldermask is to protect the copper, apart from the solder pads, from: oxidation creating shorts during soldering (bridges) creating shorts during operation due to external conductive influences creating []SM - SolderMask - EurocircuitsEurocircuits TV; Search; SM SolderMask. Solder mask is a protective layer of liquid photo image able lacquer applied on the TOP and BOTTOM side of a Printed Circuit Board. The function of the solder mask is to protect the copper, apart from the solder pads, from:PCB Design Guidelines - SOLDERMASK - Eurocircuits The purpose of Soldermask (SM) is to provide a protective coating on the PCB against contamination, oxidisation, humidity, mechanical damage and electrical shorts. The application of SM requires certain criteria to ensure that it has good adhesion, quality and reliability and the PCB layout has a major influence on this.

However, when it comes to distances between the PC traces, in my view, the IPC-2221 table 6-1 stepwise limits are mostly baseless: the curve for spacing vs. voltage should be linear. Of course, it is not the only standard that defines the electrical clearance.
