I am working with fine pitch components (15-20 mil) and having soldering problems and would appreciate some opinions. 1) How much of an effect does pad size have on bridging? 2) How much of an effect does solder paste grain size have? What is the recommended size for these applications
Our pre-reflow inspections look ok but after the oven it is shorts galore....any help would be appreciated
