I put some sample instructions for re-balling and it has been removed! It is useful and relevant information. Please justify.

I just added an xray photo of the BGA joints - does that help? DJGB 09:29, 11 October 2006 (UTC)[reply]

No further comments, so I'm going to remove the cleanup tag DJGB 10:24, 31 October 2006 (UTC)[reply]

History?

If someone knows and have a bit to tell about the development of the BGA package. Please add it & references. Electron9 (talk) 20:40, 22 March 2008 (UTC)[reply]


uBGA/μBGA/micro BGA/TinyBGA(TM)

What about these? For example, what's the exact difference between BGA & uBGA ? Like, if pitch is bigger than 0.5mm it's BGA, but if it's 0.5mm or smaller it's uBGA, or what?

If you remove the solder, from a BGA chip, are there bumps, or just pads ? Like a PCB has it's pads flat against the board substrate. --DaveDodgy (talk) 14:05, 23 April 2008 (UTC)[reply]

Finest pitch

What's the finest pitch a (μ)BGA chip has been made ? As in, the width of the pad & the spacing between pads (centres, not edge to edge).--DaveDodgy (talk) 18:25, 10 May 2008 (UTC)[reply]
