Dear all, We've got a curious problem. We have had a major problem with BGA's occasionally being placed one to several rows or columns off the pads. We are using Universal's GSM2 platform for our general purpose placements. Our Universal rep here

I am in the process of making a requirements-document for manufacturing of a PCB. I would like to state some requirements for maximum allowable component shifting in the final PCB (both displacement and rotation). However, I can't find any (IPC) sta

Not quite sure what your problem is by your explanation but if you are seeing component shifting with no real trend , I would be confident that it will be down to the Clamping of the board. Make sure the adjustable rail is secure and not moving sligh

What exactly do you mean by component shifting? If you mean lead over hang, i.e, how far off the pad can a component lead sit and still be acceptable, IPC 610 addresses this.

No need to make such a document. It is all in IPC 610.

That was exactly the document, I was looking for - and couldn't find :-) Thank you so much both of you for your help. It saved me a ton of time.

we have fuji's cp-iv-3 machine made in 1993.we are facing problem everytime when we change the jobs(for example we change from pcbA to pcbB to pcbA)even though program is same. There are some mechanical adjustments like conveyor adjusted according to
