UV Curable Solder Mask Soldering PCB Repair Green Paint 10cc & Plunger.
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)
It is used for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads.
A solder bridge is an unintended electrical connection between two conductors by means of a small blob of solder.
PCBs use solder masks to prevent this from happening.
Solder mask is not always used for hand soldered assemblies, but is essential for mass-produced boards that are soldered automatically using reflow or Wave Solder techniques.
Once applied, openings must be made in the solder mask wherever components are soldered, which is accomplished using photolithography.
Solder mask is traditionally green but is now available in many colors.
Solder mask comes in different media depending upon the demands of the application.
The lowest-cost solder mask is epoxy liquid that is silkscreened through the pattern onto the PCB.
Other types are the liquid photo imageable solder mask (LPSM or LPI) inks and dry-film photo imageable solder mask (DFSM).
LPSM can be silkscreened or sprayed on the PCB, exposed to the pattern and developed to provide openings in the pattern for parts to be soldered to the copper pads.
DFSM is vacuum-laminated on the PCB then exposed and developed.
All three processes typically go through a thermal cure of some type after the pattern is defined although LPI solder masks are also available in ultra violet (UV) cure.
