2211 WonderMASK P Peelable Solder Mask Technical Data Sheet
■WonderMASK P is a temporary, peel-able solder mask comprised of a thixotropic, synthetic acrylic latex designed to withstand fluxing, wave soldering and cleaning operations. Unlike natural latex mask, it contains no offensive ammonia and hence is non-corrosive to copper, gold, silver or pre-soldered surfaces. In addition, stability problems are averted. When applied, the product is opaque pink, and when cured, becomes completely translucent red. Cured mask can be for masking conformal coatings. May be used in applications such as robotic, pneumatic, hand applied or template screening (not recommended for silk screening).
■Techspray’s WonderMASK is the industry-leading temporary solder mask brand because of quality and versatility. Depending on the product, mask can be peeled off manually or washed off in a batch or inline system.WonderMASK has a number of useful applications in PCB assembly:
◆Thru-hole masking – Prevent soldering open holes in a wave soldering process by covering with WonderMASK. All of the masks listed below are well suited for this application.
◆Conformal coating masking – In a conformal coating dipping or spraying process, WonderMASK can be used to cover connectors and other components and areas that should not be coated.
◆Temporary component adhesive – WonderMASK can be used to tack down components on double-sided PCBs.
■All Techspray WonderMASK products have the following advantages:
◆Can be cured in pre-heat
◆Withstands lead-free soldering temperatures up to 640°F (343°C) in wave soldering process
◆RoHS compliant
