Just a bullet! My results are, .005" stencil thickness should measure between .0055" - .006" if your pressure is correct, metal blades and snap-off is set up correctly. Do you have aperture reductions at the QFP locations "typicial industry standard

Actually we're using ALPHA METAL Vaculoy 63SN/37Pb solder bars in our WAVE (ELECTROVERT ULTRAPACK 650C). With that solder, we use the ALPHA METAL LONCO SLS 65C flux. With this combination, we have many bridges and sometimes, the solder do not full co
