: Pads appearing bare or thin, leading to weak solder joints.
While IPC-7527 is a visual standard, its criteria are the baseline for modern systems. SPI machines use lasers or cameras to measure height, volume, and area based on the thresholds defined in the standard. This combination of manual visual checks and automated measurement ensures 100% inspection coverage for high-reliability products. Where to Find the IPC-7527 PDF ipc-7527 pdf
