WANTED: BGA Mad Scientists! ;)
Just curious who has underlying knowledge on replacing or upgrading (NVIDIA in particular, but any BGA experience is welcome) BGA packages instead of ordering complete motherboard's (whether new, used, or refurbished).
I have seen new balled BGA NVIDIA chips in the $10-75 range and desoldering and cleaning a BGA chip/pad isn't that hard...
What is to stop a BGA laptop owner from replacing their chip or even upgrading it in the event of a failure if they can get their hands on a balled chip (or have the skills to reball a known good chip from a parts donor)?
I understand upgrading a chip in a chassis not designed for it would require thermal handling system upgrades as well, so I'm not interested in hearing about that caveat in this particular thread.
