WonderMASK® PX is a temporary, peelable, latex solder mask designed to dry in half the time of standard peelable solder masks. It is hand applied and can withstand fluxing, wave soldering and cleaning operations. It effectively masks and protects open through-holes and underside components in a wave soldering process, and can be used as a conformal coatings mask.

WonderMASK PX can remain on all areas of the board until ready for test, and then, be easily peeled away. In addition, WonderMASK PX is ideally suited for situations where a thick coat of mask is required. WonderMASK PX has been specially formulated to cure homogenously, virtually eliminating any limit on the deposition thickness.

WonderMASK PX is not recommended for use on bare copper as it contains a sufficient concentration of ammonia to cause discoloration. For use on bare copper, WonderMASK P (part # 2211) is recommended.

Specifications: Meets MIL-STD-2000 paragraph 5.3.18 parts a, b, and d.

Applications


FAQ's

Is there a way to dissolve or wash off pieces of peelable solder mask?

Sorry, the best method is with tweezers or a brush. Peelable solder mask will not readily dissolve in cleaning solvents.

Does WonderMASK temporary solder mask contain silicone?

None of our masks contain silicone and they leave no residue behind.

Can temporary solder mask be left on the PCB permanently?
Temporary solder mask is intended to be just that – temporary. Manufacturers of solder masks, like Chemtronics, always recommend removing the mask because there is no testing to support doing otherwise. If you decide to leave the solder mask on as a permanent part of the PCB, you will have to do your own functional and reliability testing to ensure it does not cause a problem.

How To Use Spot Mask for Wave Soldering & Conformal Coating
Spot mask, commonly called “temporary solder mask”, can be used to protect open thru-holes or “vias” in wave soldering. Solder does not wet or stick to it, and it withstands soldering temperatures without charring and bubbling. When you are done, the mask is either peeled off or washed off in your P...
