Roughly every 5-8 years. IPC-7095E was released in 2020; the next revision is expected around 2026-2027.
≤25% void per ball for standard BGAs, ≤15% for critical devices.
Note: While many IPC standards are proprietary, some industry resources may provide free summaries, training documents, or compliance guides that interpret the IPC-7095 standard, which are invaluable for teams starting out. Why IPC-7095 is Critical for Electronics Manufacturing
Design and Assembly Process Guidance for Ball Grid Arrays (BGAs)
These standards serve different but complementary purposes. IPC-7095 provides the "how" — the design and assembly process guidance for BGAs. IPC-A-610 provides the "what" — the acceptance criteria for electronic assemblies, including visual inspection standards for BGA solder joints.
