way too low of yield. with that technology on the board I would expect about 98% as well. So what are the defects? and more importantly, is your design, machine(s) and/or process(s) capable of this technology? Details I am sure are forthcoming R

hai, in our smt process we are facing the following problem. The Case A tantalum capacitor used in our PCB assembly - during reflow process get shifted, due to which other components nearby that also found missing. what are the causes for this proble
