How about section 12.2.12 of IPC-A-610C? It doesn't include detailed description of root cause/effect but acceptance criteria.

Every paper I've seen published shows that BGA voids either have no effect or actually give a slight improvement. The one exception are voids with a root cause in bad incoming boards, such as champagne voiding where nearly the entire interface is go

In order to keep up with industry demand, IPC has released amendments for J-STD-001F, Requirements for Soldered Electrical and Electronic Assemblies, and IPC-A-610F, Acceptability of Electronic Assemblies. For each standard, IPC-A-610F Amendment 1 and IPC J-STD-001F Amendment 1 represents a critical shift to deliver necessary updates to these already robust standards.

There are a variety of methods one can use to rework QFNs. This paper explains one of the ways to get very little center ground voiding while making it easy to place a tiny component with almost no keep out areas.

Despite being a continuous subject of discussion, the existence of voids and their effect on solder joint reliability has always been controversial. In this work we revisit previous works on the various types of voids, their origins and their effect on thermo-mechanical properties of solder joints. We focus on macro voids, intermetallics micro voids, and shrinkage voids, which result from solder paste and alloy characteristics. We compare results from the literature to our own experimental data, and use fatigue-crack initiation and propagation theory to support our findings. Through a series of examples, we show that size and location of macro voids are not the primary factor affecting solder joint mechanical and thermal fatigue life. Indeed, we observe that when these voids area conforms to the IPC-A-610 (D or F) or IPC-7095A standards, macro voids do not have any significant effect on thermal cycling or drop shock performance.
