Beyond the massive BGA, the hundreds of amps, and the HBM heterogeneous integration, what scraps an entire batch is often something as mundane as solder paste uniformity or a leftover via stub. During one trial production run, X-ray inspection after chip soldering showed a void rate sitting right at the IPC 20 percent threshold \u2014 but the design team required it under 15 percent, or local hot spots would trigger throttling under full AI training load. This article walks through what it actually takes to keep an AI accelerator board alive."}
