We are running SMT products and have been for some time now. First, I wanted to check with you folks to see what an acceptable FPY rate, or what you would consider and acceptable rate, is. Secondly, we are having issues primarily with product that

98% to 99% pass yield should be your target. The previous company I worked for, we were able to meet these goals with most all of our products. It took us some years to achieve this level of pass rate. Of course analyzing and good reporting from some

| Does anyone have an idea of what a good placement rate (pph) is for a low volume, high mix smt line? We do small lots (10-300pcs), with a feeder count that ranges from 28 to 130 per setup. We have low volume machines (an old (real old) Siemens HS-1

Steve, Basically in answer to your question, there is no real set number for defects. Defect rates will vary between products and companies. If my company was running the same product as yourself then there is no reason to suggest that the defect ra

My old company (CM) ran SMT to 50ppm including some very complex boards. We established the normalizer number by: #components + #solder joints. As was stated earlier, the ppm for any given product is the result of many factors. You may get differen

I would suggest 1) Use the profile that is suggested with the BGA types you are using or 2) Have you solder paste rep visit for a half day and help profile your machine. Remember if they want to keep you as a paste customer they will help. Enjoy,

Hi, It sounds like your a little new at profiling, and can be difficult to do well. We purchased a KIC profiler that has software that will take your profile data and tell you the best oven temperature settings and conveyer speed to use. You need

I can't offer much advice on acceptible rates or #'s. From a process standpoint, most of your bridging or insufficient originates in your printer. Look into buying dedicated tooling specifically designed for the build. We use "h-towers" on all hig

Thank you. I spoke with our SMT guy, and he stated that there is plenty of board support on the pcb. So it's not a matter of flexing. There just seems to be inconsistancy in the solder application. He did mention that part of the problem is a lac
