Differences between Solder Mask & Paste Mask

Here are some differences between solder mask and paste mask: 1) The openings on solder mask layer have no solder mask ink, but the openings on paste mask layer have paste. 2) The solder mask layer is one part on the circuit board, but the paste mask layer is not. Paste mask layer is just for the stencil. 3) Solder mask is used for applying solder mask ink, but paste mask is used for applying paste.

Solder mask - Wikipedia

Printed circuit board with green solder mask coating. Solder mask or solder stop mask or solder resist is a thin lacquer -like layer of polymer that is usually applied to the copper traces of a printed circuit board (PCB) for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads.

The typical ,solder mask, thickness (perpendicular to the board) is at least 0.8 mils. ,Solder mask, will be thinner near the edges of traces and can reach as thin as 0.3 mils or less. In general, you’ll want about 0.5 mils of ,solder mask, over your traces. Sprayed epoxy ,solder mask, can take a more uniform thickness throughout your PCB.

Paste mask, on the other hand, is a material that is applied to the areas that have been left uncovered by the solder mask to assist in the soldering process. The paste is commonly used to connect surface-mount components to pads on a PCB during soldering, but it is can also work with through-hole pin-in-paste components by using a stencil, a syringe or jet printing to apply the mask in or over the holes.
