So far, we have not found x-ray systems to be all that
helpful with BGA inspections.  The main issue is that there is still no way
to see if the balls are actually soldered.  Alignment and shorts can be seen
though.

                        Hi,

                        We're starting to look into x-ray systems,
specifically for BGA inspection.
                        Units by Glenbrook caught my attention due to their
low cost relative to
                        other units on the market.  Anybody have any
feedback, positive or negative
                        on their products?

                        I'd also appreciate any other insight you might care
to share regarding
                        other vendors and BGA X-ray.

                        Thanks.
