The Techspray 2211-8SQ is a non-ammoniated, low odor peelable mask that prevents soldering protected areas in a wave soldering process by applying a Peelable Solder Mask. These products are designed to apply smoothly, dry quickly, withstand high lead-free process temperatures and then be removed easily. WonderMask P is a temporary, peelable solder mask 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.

WonderMASK P 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. WonderMASK P and PX are recommended.

Temporary component adhesive – WonderMASK can be used to tack down components on double-sided PCBs.

All Techspray WonderMASK products have the following advantages:

• Withstands lead-free soldering temperatures up to 640°F (343°C) in wave soldering process
• RoHS compliant
