I have been working on a project to optimize our smt line. One of the things I wanted to do is panelize the boards. Because of card edge features the boards would be rotated 180 deg from each other. I am being told that the Universal GSM line has intermittent placement problems populating boards 180 deg from each other. From what I understand, the placement problems have been seen trying to place BGAs of fine pitch parts(<20mil). We have Universal GSM 4681A pick & place with FlexJet heads, running OS2 operating system, and Ver 4.5.0 of the GSM software. Has anyone else experienced this or something similar? Does anyone know of a fix or work around? Thank you.
