What we have had recently is a lot of larger thin (32 thou) thickness boards that have had issues with SC90 diodes bouncing off the pads in the final PNP machine. Our setup, universal instruments GC120 or quad beam 30 spindle lightning heads. This m

I am looking at buying a pick and place machine to assemble the circuit boards we make. Most of the boards are small (2 to 10 square inches), most are 2 sided, and have maybe 20-50 parts per side. I use mostly 0805/0603 chips, SOT-23, SOD-123, SOIC

You mean you don't pull all of your thermocouples out of the ovens once a year and send them out for calibration? - lol Tough question. You have a calibrated datalogger. (I assume) You have an oven with preset zone temps, each zone controlled by a

I�m suddenly getting a very high failure rate in a TO99 component (National LM136AH-2.5). After some investigation we found some of these parts are more than 20 years old. What I am hoping for is that someone out there can help me find some standards
