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
The primary challenge with BGAs is that their solder joints are hidden beneath the component, making visual inspection of a finished solder connection impossible. Consequently, the design and assembly process must be extremely precise to ensure a reliable, high-yield product. IPC-7095 directly addresses this challenge.
Contract manufacturers (CMs) and original equipment manufacturers (OEMs) typically mandate adherence to specific IPC revisions in legal master service agreements. ipc7095 pdf link
