This epoxy is designed to withstand the chemicals, heat and can adhere to materials common in PCB assembly. It has been used since 1998 and can be used in a variety of applications including but not limited to pad and trace repair, solder mask repair, baseboard material repair as well as numerous others.

If plugging the via is not feasible, tenting with solder mask is another viable option. Please work with your PCB supplier to come up with the most effective plugging process. Figure 6 shows the square and circular apertures in the center slug to reduce solder volume.

Baking the PCB will sometimes correct the improperly cured mask or laminate condition Substituting a more viscous flux or increasing the quantity of flux put on the PCB Correcting the drossing problem in the wave White Haze on Solder Mask Recognized by a white haze on the nonconductive portion of the PCB that cannot be removed by washing. 22.214.171.124. Solder Mask Defined Pad. In an SMD pad, the solder mask overlaps the surface land pad’s copper surface. Refer to Figure 3 on page 6 for the Side View of NSMD and SMD Land Pads. This overlap provides greater adhesion strength between the copper pad and the PCB’s epoxy/glass
One of the reasons was because when the PCB Solder Mask was first produced, the base resin was a brownish yellow and the hardener was a muddy brown. When you combined these two components to form the PCB Solder Mask, it turned green.Another reason was because the color green has been proven by many scientists that the color is the most visible and noticeable to the human eye.

Solder mask, also called solder resist or solder-stop mask/coating, is a thin layer covering copper traces without necessity of soldering on a printed circuit board (PCB) on both top side and bottom side to help ensuring PCB reliability and high performance. The BEST solder mask repair kit can be used to repair solder mask (as well as lifted pads and traces) as well as build up and repair edge corner damage to PCB’s. Add some colorant and you can repair mask of differing colors.

Aug 06, 2020 · Higher imaging efficiency and throughput levels with LUVIR are particularly achieved on all conventional solder mask ink types and colors (green, blue and black) as well as on legend inks (white), further eliminating the need for PCB manufacturers to transition from conventional standard ink material to more expensive DI inks, a change which normally requires lengthy and costly re-certifications of solder mask processes by end-customers or PCB designers. Dec 11, 2018 · The worst scenario is when dealing with closely spaced solder tracks and pads; one wrong move and you’ll end up shorting connections with solder. The answer for this predicament is the use of a PCB solder mask. Solder mask is actually the green (or sometimes other) color you see in mass produced PCBs. Top Solder Mask Layer Shown in Purple If you’ve ever seen a PCB you are no doubt familiar with their oddly green coloring. This thin green protective covering on the top and bottom of a PCB is called the solder mask and it helps protect traces from shorting when debris is present on your PCB.
