I think I have the vision problems figured out. There were two problems. 1) The Alignment type was set to "Small" for my TQFP48 part. It should have been set to "Complete". This is a clear case of poor documentation. The AutoProgram manual lists the

Hi all! We are placing BGA's using a QSV-1 pck and place machine. I believe our profile has the correct information but we continue to get vision results not available when we inspect the part. Our screen appears as follows: NO RESULTS AVAILABLE PAR

We have also had this problem. I have managed to get around this by selecting a teach video model and positioning the teach window to include half the pad on the left and half the pad on the right so that the center point is bang in the middle of the

Hey everyone, I hope all of you doing well this time of the year. We have an old Juki / Zevatech 740 pick and place machine and we got a problem with the vision alignment, every placement is off by 2mils. How can you run an offset calibration on t

I have never run across that error message before. Does the machine have Upward vision? Does this message only occur when trying to run programs that were generated by Autoprogram ? I think that I would create a new program with only 1 component, a r

I am having the same problem with the MPM Accela solder paste printer machine. If the fiducials are adjusted for PCB alignment, the location of the paste is then wrong, and vision inspection fails. This is a problem for both pad preview inspection

It's not the z pickup or profile bot thanks for the help, I think Mike is right. I have used these profiles hundreds if not thousands of times in the past and never had an issue. Also it was different components and different profiles almost every ti
