i would agree with taking a closer look at the fiducials. I have the same line config. here but have to say that I have never experienced any conflict between machines. One thing I have seen before is when we ran a particular product on the machine

If I've been clear, the parts become offset as the XY table moves around, without fiducial correction. It's when it does a fiducial correction that the placement is alright. If the placement is excellent, and I just zip the table around...load posit

It sounds like the XY data you are receiving from your customers is unreliable/inaccurate. This in turn is causing down time on the machine to adjust the placement and rotations. Fell free to contact me off line and I can suggest some alternative

hello, I suppose you didn't put any placement offset in the component placement settings. did you perform the general calibration of the lasers? with the supplied calibration tool that comes with the machine. check MSP parameters, as there might b

This could be what we call a "non-problem". If your print is off slightly, yet after reflow there is no solder related defects, it should be considered OK. Move your inspector from the printer to right after the oven. This would enable them to ins

Does anyone know of anybody who makes a device to take Gasfets off of tape and reel trim them to length and present them to the machine (zevatech, juki) for placement. An alternative would be to take them off tape and reel trim them and re tape and r

That is the optimal solution. Most placement equipment have very accurate methods to count the fall off per part/nozzle/feeder. Tie that together and you would be golden.

I have a Product with 2 Different PCB Fiducial allocation in the Design. It has 4 Fine Pitch components. The first PCB DO NOT have Fiducial Mark on the board itself BUT has Fiducial on the Break-OFF Tabs. The second PCB has no Break-Off Tab but has f

Check them before the oven for cracks. (after placement) Don't just look at them, take them off the board and check. I"ve seen resisters that were broken by the machine but you couldn't tell untill you took them off. If they are cracked check the co
