Hi. Sorry I don't have an answer for this but I have the same problem in the "Y" axis on one of my 4Cs after the machine has run for around 4 hours. The machine seems to partially correct for the pick-ups being off as the placements are fairly good

I don't think it is a loose camera lens. We are actually off on the position of the Z-rod. It's not just the camera position that is off. We really can't change nozzles because the z-rod misses the hole in the nozzle changer. We have repeatedly clea

If 3-5% of the attempted parts placed are dropped, you have a serious problem...that's 1 part dropped for every 20 or 30 placements. Does it mean that it drops the part in the scrap bin and then successfully places the same part or would the board co

Without PCB layout, not much would get done. It is a ubiquitous need across industries; Industrial, consumer, military...Everywhere you look, there are chips soldered to PCBs to create a final product for the end customer. But where did we all learn

The method you suggest is about the only way to �clean-up� this terrible situation. Realistically, this is a "memory" type condition induced by design, build symmetry, "cross ply construction", excessive cool down rates during lamination or reflow a

I am trying to make a PCB populated with complex components such as LGA, WLBGA, LGFP, LFCSP, VFBGA, QFN, FBGA, PBGA so that we can test out some PnP machines. I have found parts on digikey for each of the packages we want to test but trying to make
