hi Stephen, Thank for your comment! Yes! My people also share the same view that customer is asking something which is in more theoretical side. They want us to collect a lot of statistical data to prove our process. Anyway, customer is not only

HLY: If you must build product while you wait to get the printer fixed, and if the BGA balls are eutectic solder, your approach is a good one. All solder paste does in this assembly application is supply the flux. Additional solder volume is not ne

Good day, 2D inspection requires correct adjustment. In the other case it will cause continuous problems and false alarms. Adjust the lightning first and choose the correct process limits second. Look at histogram when you are adjusting the camera

Hi Nuez, We've run a number of different brands of SMT Elco's through a number of leadfree temperature profiles, and consistantly the best performers were Elna & a very similar own brand product (not listing here as it was one from a sister company

Hi AJ, Depends on what machines you are running, how you run them, and if you have the spare components on feeders lined up ready to go. On a volume job using CP's using both feeder banks on change over I'd be upset if they stopped for more than a
