My 2 cents... Screen printing may very well have a leg up on deciding SMT defects... however if you pay attention to your stencil (aperture size ratio etc..) and inspect your prints... I believe its a much lesser number... (paste MFG also plays a ro

Here's part of what I could read: "We evaluated the influence of Lift-off (Fillet-lifting) and the influence of thermal fatigue, in this case on combination between various terminal platings of electronic components and Pb-free solder, Sn-37Pb solde
