Hi,
        Here we allow to change a BGA to a maximum of three times. But I don't
think it's based on any standards or spec. It's just a number time that give
us good balance between the board integrity and the cost of rework.

Subject: [TN] BGA rework


TechNetters,

I am sure there has been some discussion on this subject in the past, but I
need to ask a fairly simple question (I hope).  Is there a limit to the
number of times BGA packages can be attached to and removed from a BGA
before the integrity of the board is compromised?  Is it in a spec
someplace?
Thanks in advance
