About Solder Masking Dots and Tape, Masking for Soldering & Conformal Coating

Designed for masking component holes or areas on PCBs during wave soldering or conformal coating, these pressure sensitive masking discs will withstand a five to eight second exposure to molten solder at 250°C. There is no adhesive transfer when the discs are removed, the rubber-based adhesive containing no silicones. Discs should be removed before solvent cleaning. Solder Masking Dots are available in 51 diameters as standard, from 3mm. Special die-cut shapes, either rectangular or any irregular shape can also be manufactured on request.

The special impregnation of the discs will not allow most conformal coatings or varnishes to adhere or wet. Consequently Solder Masking Dots are excellent masks for this purpose, allowing easy removal and a well defined mask area.

Die-cut discs eliminate the need for tedious cutting of masking tape by hand (especially for smaller areas) and will speed up production accordingly. No curing is required. Dots up to 50mm diameter are in a continuous string of overlapping discs for ease of application – peeling off one disc releases the next off the lining paper.

INT 119 Solder Masking Tape is the same material but in a roll form.
