Many solder suppliers also offer temporary solder mask. The problems you can expect from some of these masks are: - Adhesion problem at high temperature - Compatibility with the wave flux you use - Printability issues (if screen print) - Residue left on pads after removal - Compatibility with your wash equipment (if water soluble) - Cure time - Fracture druing thermal cycle (Thickness dependent) Internet is a very good sources to start your search. Hope this helps, Michael Yuen ---------- From: TechNet-request To: TechNet Subject: Temporary Spot Solder Mask Date: Wednesday, July 23, 1997 11:30AM We are currently testing and looking at a latex peelable, a water-soluble, a UV peelable, and a UV water-soluble. I was wondering what type of temporary spot solder mask was out there and what type are companies using and why? I would also like to know if there were any problem that occured with the spot mask during the wave or cleaning process ?
