Dymax Speedmask® 9-20479-B-Rev-A UV/light cure temporary masking agent is specifically designed to meet the needs of the electronics industry, where its fast cure and simple removal will improve productivity in printed circuit board assembly. It is formulated for the protection of pcb connectors and other components, either during the soldering process, or during conformal coating. This temporary mask for pcbs also features a particularly tight viscosity tolerance which aids in maintaining good process control during application. And it’s blue in colour, so you can see where you have applied it.
Speedmask 9-20479-B-Rev-A maximises production speed as it cures in seconds under UV/visible light and is solvent and silicone free. It is benign to gold or copper finishes on connector pins or other components. It is extremely thixotropic – flowing easily and consistently with all forms of manual, semi-automatic or fully automated dispensing and then forming a stable coating prior to a fast light cure. It is easily and quickly removed by peeling, leaving behind no ionic or silicone contamination.
It joins our portfolio of temporary masking products for electronics and surface finishing applications. We have talked before about how productivity enhancements flow from these kinds of materials. This infographic illustrates the advantages of using Dymax UV cure liquid maskants in temporary masking for electronics, including an example of a 30% process improvement.
