Hi,
My Opinion:
Unless there was a cost and technical justification for allowing the cap
to remain it is a reject.

Please see the link below.
Cap under BGA.
Inquiring minds question: If the board tested out OK, would you ever
consider just leaving this here? The part is a ceramic cap.

Hi Genny,
I have your picture posted:

It depends. First thing I would want to know, what is this? Is it metal?
If it is, it would be a violation of electrical spacing and I wouldn't leave
it there.
Does the ball have any function? Some balls have no function.
What is this board for? A critical application? If it is then no.
How scarce is the BGA?
There's a lot of "it depends" that would have to be answered before I would
consider it.
My first reaction is that I wouldn't leave it there. But there may be some
circumstances that I might consider it.
Steve
