Solder mask or solder stop mask used for printed circuit board (PCB) designs is a thin lacquer-like layer of polymer applied to the copper traces for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads. In electronic design automation, the solder mask is treated as a layer of the PCB, such as the copper and silkscreen layers.
Even though this may sound complicated, Altium Designer’s easy-to-use software helps you step-by-step through the entire process of PCB design from your initial idea through all the detailed steps to manufacturing. Altium Designer software documentation is easy-to-implement and delivers enhanced PCB design tools as part of one single price solution.
Altium Designer features include:
Automated procedures for implementing PCB mask
Expansion rule for applying value to obtain the final shape on the paste mask layer
Paste mask expansions can be defined for pads on an individual basis
Further options available to follow expansion defined in design rule
