Can someone direct me toward existing INDEPENDENT studies done on comparing various SMT equipment (particularly P&P)? I am currently involved in evaluating SMT equipment for a low to medium volume, high mix, specialty PCBA's (high temp & vib with possible TAB applications). As with any consumer issue, I'm getting varied reports on what the equipment can do. I'm getting the "Our latest software rev will take care of that" speech on some equipment. Also, I am attending NEPCON East to get more info. I was wondering other than comparing spec.'s (speed, accuracy, heat profiling, etc.), what are the intangibles that need to be considered?
