Doug, Have you tried running the boards at an angle to the wave of between 15 - 30 degree's ? I've done this on a few boards to eliminate short's and I believe it will work on your problem very sucessfully. Best thing to do is get your wave solder c

| Has anyone had any experience or data using vibration during the reflow process. | We introduced a vibration device attached to the fixed rail on a Vitronics reflow oven. The reason was to prevent skewing on large PLCC devices. The process worked v

Hi guys, I need your advise on this, I have a very uncommon PCB design (at least for me, I've never seen anything like this...) it is 32" x 18" x 0.062" and has 9 QFNs that are driving me crazy, I'm not able to get a good alignment, I can get a mediu

Hi All, I've been in the CM world for a long time and it seems like there has been little change in the packaging techniques used at the end of the day. Assembled circuit boards in small/flex volume are bagged or bubble wrapped and boxed up to ship

You'll have to do at least 2up array since most conveyors won't handle boards less than 2in wide. I'm assuming it's FR4 lead free temperature material and PCB's are scored in the panel. The 13-16in lengths aren't a problem other than depaneling. With

We have these thin and flexible sheets of fiberglass that we sometimes use to send boards through reflow that can't ride the edge hold fingers. We've had these sheets for a decade at least and have no idea what they are or where they were purchased
