Hey everyone, We use a MyData MY12 machine and we are experiencing a problem with the Midas head. I recently replaced a torn vacuum tube that goes on the zfib card. The machine worked perfectly for a day and a half but now MY12 has completely stoppe

all, The placement was off on one panel ( 4 up ) out of the batch. It was off by approx 1mm in the y-axis. No obvious faults found with machine. Any experience of such problem - I am guessing this is a sign of something wearing on the machine or s

We recently scrapped our TP9-2U because of an issue similar to this. The X-axis would overshoot the pick and place positions. This particular machine(2U)only has 1 X motor. The UFP's and the MY machines have a small fine positioning motor that is on

We have a TP9 and are having no problems placing 0402s or fine pitch QFPs. Try slowing down the accelerations on the X and Y axis. That increases the time it takes to place a part but I have found that it can help accuracy. All the other posts hav

IF YOU READ FIDUCIAL MARKS THAT ARE PARALLEL TO EACH OTHER THE PLACEMENT WILL NOT BE AS GOOD. ONE OF THE PROBLEMS WITH THIS METHOD IS IT COMPLETELY THROWS OUT THE CONCEPT OF BOARD STRETCH IN ONE AXIS. THE OTHERS MAY VARY DEPENDING ON WHAT MACHINES YO

Don't try the mecha check yet unless you know how. have you checked the coupling shaft of Y-axis? If it's ok, take a look at the ball screw if it looks like being scratched or something unusual. Also, observe the movement of the machine if you hear a

Hi Tim, 8-mil huh? Boy, that's getting down there...you know, placing 8-mil is one thing, but printing solder paste on 8-mil pitch is another. Most of the time when I've seen 8-mil pitch on a board it's been attached with hot-bar...but I guess

This type of component packages works best with vision type: 254 - irregular. Measure the total package length including the leads. Also set the body dimension x-y tolerances to at least 0.35mm and the the pick up x-y tolerences to 0.5mm in the part
