One thing I have run into when placing cap's flush to the board is blow holes due to the plastic sheathing used around the cap. It would form a gasket going through wave and exhaust out of the holes therefore blowing the solder out with it. This cap

I purchased a used QUAD 4C -136 and after a few months got the machine running 8 hr shifts. One issue I have come across is feeder drift. I kept re-aligning the feeder pickup positions but they would always change. Finally I got the time to measure

I have seen that moisture in pcbs will cause mid chip solder balls. To discount this, take one pcb from a batch that is giving you solder balls and pass it through you reflow oven with no paste or components on (bare pcb)using your normal reflow prof

I'm bringing a GSM-1 machine at a university back to operational condition. I have a project created and I'm experiencing that when it's loaded the PWC goes to a location that is about two inches too narrow. When the PWC is manually told to go to a

In HASL pcb coating you need to fully coat the pads with solder and then blow off any excess solder to leave a nice coating on each pad. Generally pcb manufacturers try to give you a flat pcb pad to make your solder paste printing more consistent. To

Thanks for the help guys. Nice to think I was basically on the right path. PCB manufacturer has finally conceded the barrel defects and is remaking the PCBs. We are big on pre-tinning the leads of TH connectors as well as providing some good pre

Has anyone had any luck programming using the side cameras to inspect for defects on the sides of chip components? We recently had an escape of a damaged chip capacitor that was impossible to see from the top camera but was clearly visible with the

Hello Scott, Simply program the side angle cameras as you would for any other device using the downward camera. For instance, solder joint inspection for a PLCC would utilize a basis window, bridge inspection algorithm and individual solder joint i
