yes there is Caveman, (well maybe depending on your circumstances) you need to purchase a manual printer and print the connector then flip and print the other side. (you need a manual printer so you can print after the parts have nbeen reflowed, we

Hey All, Thanks for all of your help to date. While running the nozzle height test I noticed that the Z-rod is bent. Probably happened after setting the "X closed loop soft home" back to 50 from 384 which was probably why the nozzle slammed into t

Greg, All the above. It looked like it was going to be a drop for SNPB HASL at first but after a few thousand boards we started running into all the problems you are describing. We first started seeing non wetting on SMT pads. The solder would wet t

Thanks for the posts guys, I'd like to mention a few things... In my opinion, the tooling does not get any better than this. The board is fairly small and quite stiff. There is no board warping. The tooling plates are tight and the vacuum really h

Hey all, I just though I give you all a quick update. I managed to get the printer working. The problems were a combination of everything that was discussed here. When I adjusted the GS4 pot for the histogram, I turned the wrong one at first. This t

It all has to do with charges being drained. IIRC the pink stuff won't build up a charge but doesn't drain it well. As for the need for mats, how are charges being drained now? I don't think you can have no charges building up. With ESD all you can

I assuming that you already have checked the fuses? Also, check all the power: +5V, +12V, +-24V, etc. We had to change our PSU once, after a major power-drop due to a thunderstorm. But you should be ok if you can pinpoint what type of voltage you are

I still think the best bet is probably an SMT pre-bake operation to ensure that there is no moisture in the board. Vapor pressure is usually the leading cause for delamination, so removing the source should significantly help out. Unfortuantely, pr

Hello bpeach, We purchased a Mirtec for our first AOI machine after a side by side comparison of three different manufacturers. The Mirtec proved to be far superior to the others that we had looked at. Initially, the intention of the AOI was to prov
