Hi, Based on our experience, you can collect X-Ray analysis of solder joints and calculate values of SPC (such as PP/PPK and GR&R). Now, you can find, based on this calculated values, if your production is good or not. Also, this helps you to detect

I know this may be a long-shot, but I can really use the reach this forum has. I am looking for an injection molding material called Noryl. The specific compound is SE1X-71944. If you have any of this available, or know someone that does, please repl

Dear Dreamsniper, A big hidden cost in any cleaning system is the cost of diminished production and rework. I assume you are cleaning the adhesive stencils manually since there is no equipment cost in your formula. Manual cleaning of adhesive sten

Craig, I'd be really hesitant in pursuing this method for a TQFP. Remember, most SMD's are rated for a maximum rising slope of around 4C/Sec. Immersing a fragile TQFP in a hot wave of molten solder will probably exceed this ramp up rate. Besides thi

Dear Ashok, My practice is that if you see it as a source of a potential problem, label and monitor/measure/test it. OK, so it may be a lot of work up-front, but what is the risk involved in not doing it ?? There is no grey area, do all or nothing
