Why not quantify the amount of time spent taping apertures every time you want to use the stencil vs. the cost of a new stencil (about $300, usually)? Look for problems that are created by the blocked aperture method - is there rework down the line t

Hi, Yes, we just built a new plant, and used copper again. The stuff we cut out of the old building was copper, and it was fine without any issues. We lay it on an angle so condensation flows to an end, and can be periodically vented, and we take a
