Solder mask Thin lacquer-like layer of polymer that is usually applied to the copper traces of a printed circuit board for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads. This curing process cements the solder mask in place permanently, and the durable material is extremely difficult to remove from the board afterward, lending to long shelf life. To ensure that the LPI mask is cured in the proper locations, negative film stencils of the top and bottom solder mask Gerber Files are printed using a contact printer.

Solder Mask Expansions. An opening in the solder mask is automatically created by the software and is the same shape as the via. This opening can be larger (a positive expansion value) or smaller (a negative expansion value) than the via itself as defined by the Solder Mask Expansion setting. The expansion is measured from the edge of the copper.› Specify the solder mask thickness. Solder mask also has a dielectric constant. Even thickness across the board can prevent unpleasant surprises. › It is always a good idea to do some post design simulation or signal integrity analysis. It’s always less expensive to fix the design before the board is manufactured.
