We've seen issues with Elco's for years on boards with a lot of copper (higher than normal temperatures. We found that the 250C caps failed on the "burn in" tests as they has lost a lot of electrolyte in the reflow process. On some brands you could

Calibrating the fixed camera (this is the camera that is mounted in the feeder base), I dont recall there being a procedure for calibrating it. You need a special nozzle and a plate that sits on top of the camera and you calibrate it in the system se

I'm considering buying a UIC Advantis P&P machine. I'm worried about the huge, additional cost of new feeders. We've been running GSM's for years so we have tons of GSM vibe bases, tracks and feeders. UIC tells me that old pneumatic GSM feeders ca

Even Quad couldn't get the machines running right (chuckle). If it takes a Quad Field Service Engineer to run a machine what good is the machine? I suspect you have little experience with other equipment makers. Which explains your fierce alleg
