SOC BGA NVIDIA Design - GPU - Hardware - NVIDIA Developer …
Mar 24, 2024 · Is it possible to implement BGA balls of different sizes, and what is the purpose behind it? Another possible conjecture is that the variation in solder paste quantity between the inner and outer sides of the PCB may cause a difference in ball size after reflow."
Ball grid array - Wikipedia
A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package.

BGA reballing and reflowing, how to actually repair dead GPU chips?
Feb 12, 2022 · To my understanding BGA reflowing is a technique which aims to reconnect bad solder joints on a BGA chip, BGA reballing is a technique to desolder and then resolder a BGA chip both aim to do the same thing although the latter seems like a more "clean" way to do it.
BGA usage on High-END Video chips? | Tom's Hardware Forum
