The primary non-destructive method used to identify bridges, opens, voids, and misalignment.
Voids are pockets of trapped gas within a solder joint, often caused by outgassing volatile compounds in the solder paste flux during reflow. IPC-7095 provides clear, quantified thresholds for acceptable voiding. Generally, the standard sets a maximum limit of when viewed via X-ray imaging. Crucially, it differentiates between benign voids in the bulk solder ball and high-risk voids located at the pad interfaces (intermetallic layers), which compromise mechanical strength. 2. Via-in-Pad Implementation

Released to address the industry-wide shift toward lead-free manufacturing (RoHS compliance), the "C" revision focused heavily on the mechanics of lead-free solder alloys (such as SAC305). It provided the first deeply comprehensive look at voiding criteria tailored to the higher reflow temperatures required by lead-free processing.
