Stencil thickness, aperture design, and volume repeatability.
Voiding is one of the most debated topics in BGA assembly. IPC-7095 establishes clear guidelines for inspecting and classifying voids using X-ray imaging. It clarifies acceptable void percentages by area and location, helping quality control teams differentiate between cosmetic anomalies and structural failures.

One of the most important aspects of IPC-7095 is establishing acceptable levels of in BGA solder balls. Voids are inevitable due to flux outgassing, but excessive voids can lead to joint failure. IPC-7095 defines how to measure these voids and when they constitute a failure. 2. Process Optimization Stencil thickness, aperture design, and volume repeatability
IPC-7095 is the only place that defines the "temperature profile" for BGA removal and replacement without lifting pads or causing "popcorning" (moisture explosion). It clarifies acceptable void percentages by area and
