GerberGrab does exactly this, and it's low cost, and you can use it for a month for free. It is a sophisticated but easy to use reverse engineering tool which will automatically generate top / bottom BOMs with placement and rotation after teaching of

I would ditto CAL, we have a jewel box 90 with the 5 axis and we love it. I really like being able to tilt,rotate,and move side to side front to back, Angle viewing under a BGA can be very informative as to the quality of reflow in seeing ball coll

Hello all, and thanks for the responses. 1. I have changed feeders/ It's not the feeders 2. Parts are being pre-rotated 3. All other programs deleted out of machine 4. Ran parts on sticky tape/ same problem Ken : That is a very valid observation th

I would run scale calibration first (for the suspect camera). That may be your only problem. However, if your having a rotation issue and all major angles are off (differently) then it is most likely R-axis accuracy. However, I would run AMF and

I've used standard Nikon for years. We evaluated the Mantis and while first impressions were positive but with continued use EVERYONE chose to move back to the standard eyepiece. A lot depends on what size components you're dealing with - when you s

Try this... set them on the back and teach their pick up position as stick feeder, change pick up rotation to -90 degree. before you optimize the program, change them to 8mm feeders , them optimize the the program as feeder fix. after the program

My recollection of the 4c is fuzzy but I know that there's a ribbon cable on the head that gets some abuse when the head rotates. Seems like mine would eventually break at the crimps and I had to replace it a few times. Eventually I bought the parts

Hej back at ya Your connectors could be warping during reflow. Find out by putting a connector on a hot plate and increasing the temperature. If so, you might get away with a simple fix of rotating the board 90* on your reflow oven conveyor. If you

Yes agreed you're 100% right on that. You always want to go for the full CAD file or the XY rotation file first. But like a lot of contract manufacturers and some OEM's find they have to work with Gerber only data for certain projects. The Unisoft s

Thanks for the feedback Rob, Yes that is a no solder. There are 7 of these parts on each board and around 30-40% of the time the leads will have a no solder. I have to agree with you on waving surface mount components; I try to steer clear wheneve
