Protects plated through holes and contact surfaces from solder during soldering operations
Mask areas during conformal coating applications
Mask can be applied using robotic, pneumatic, hand
applicators or template screening. Not recommended for silk screening applications.
Apply a 0.75mm to 1mm coating for best results to desired area. Wondermask P
may be thinned using deionised water. The substrate should be free from grease,
oil, and particulate matter. Drying times depend upon ambient humidity. Under
normal conditions Wondermask P will cure in 1 hour at 25°C; however, cure
can be accelerated to 30 minutes at 65°C or 20 minutes at 82°C. Do
not over cure as blistering of mask can occur causing removal problems. Mask
will change from an opaque pink to a translucent red when complete cure is accomplished.
Mask does not have to be completely dry to withstand soldering operation; however,
it should be completely translucent before removal. Removal is by peeling off.
Dried mask is not soluble in water or solvents.
Test results indicate that this product is suitable for lead-free soldering, which often occurs at higher temperatures.
Please evaluate in your lead-free process.
