WOW Sr.Tech, 40K worth of bent tools? I'm about ready to be sh*t canned because of 1K's worth. As for trimming the mags, the product is running fine (many boards) and then out of nowhere the tool bends, so I assume my PERFECT operators trimmed the ma

Hi Gary, With plastic BGAs it is more difficult to remove the trapped moisture because of ground planes in the substrate. If your parts have been sitting around for a long time they may be soaked with moisture and in some cases the 48 hours bake cy

We have a Hoover_Davis label feeder. We use on size label for most of our products so it works well for us. It's a well-built machine. We had some problems with the label in particular, so we had to buy from a different source. It runs great. If you

We are also looking for AOI machines, pre- and post-reflow. We already tried one machine from the UK (I don't remember the name, I perfer to forget we ever had it) and they told is it would do everything we wanted. Maybe so, but not well enough. It s

I have also seen this before on a CP6. We had an issue once on a CP where the shaft was coming down too far at stn 1 for pick up and forcing the nozzles up and sticking in the windmill. Check that the correct spring type is being used. Also, maybe

Start by verifying the component definition, the thickness is critical. HSP 4796 uses nozzle 81 for 0402's. Make sure is using the right nozzle. If you need to, use the autoteach function to physically teach the dimensions of it, thickness included.

I don't work on quads but I can give you some things to look for... Each of the moving axis work off a motor that is controlled by a "drive". Some of these drives have a fault or error output that is connected to the motion controller. One of your
