Solder mask, or solder resist as some fabricators refer to it, is a protective material applied to the exterior surfaces of the circuit board.

However, before the board is sent to the assembler, another step must be completed to help protect the board: apply the solder mask. Ultimately, all of these layer pairs are composited together into one multilayer circuit board, the holes are drilled, and the finished board is then ready for the assembler to install electronic components. This same basic construction is used for the layer pairs of multilayer circuit boards, except that the copper and dielectric materials are thinner and don’t include the solder pads on the inner layers. To fabricate a double-sided circuit board, dielectric core material is sandwiched between two layers of copper connections consisting of component solder pads, area fills, and connecting traces. Solder Mask and Circuit Board Fabrication paste mask and detail what PCB designers need to know when working with these layers in their circuit board layouts. This article will look at the differences between the solder mask vs. Setting up your PCB CAD system for both solder mask and paste mask layers.Ī laser-cut stainless steel solder paste stencilĪ standard printed circuit board typically requires two different types of layers, referred to as “masks.” Even though they are both referred to as mask layers, solder mask and paste mask layers are required for two completely different parts of the PCB manufacturing process.
