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. ________________________________ From: Steve Gregory [mailto:[log in to unmask]] Sent: February 11, 2011 10:37 AM To: Genny Subject: RE: What would you do? Hi Genny, I have your picture posted: http://stevezeva.homestead.com/part_under_BGA.jpg 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.
