Hi everyone,

  I am a contract manufacturer who is in process of implementing BGA
placement.  Our P&P machines are capable of placing them so that is taken
care of.  However,  I need information regarding:

1. BGA rework stations(manufacturers, avg cost, user friendliness)

2.  temperature profile of BGA reflow if differ from other types of
components(e.g. QFP, PLCC)

3. X-ray inspection(what industry trends, if any, are currently being
used to inspect BGAs(100% x-ray inspection, little less, or none) , are
there facilities that will X-ray them for cost, and if so what is avg
cost..)

I am on a fact finding mission, so any input would be greatly
appreciated.
Thanks in Advance.
