The IPC-7801, titled Reflow Iron-Solder Softness Standard, is a technical document that provides the industry-accepted guidelines for evaluating the "softness" or thermal-mechanical properties of solder joints formed during reflow soldering processes.
Visual inspection (governed by IPC-A-610) is subjective and only catches visible defects. IPC-7801 introduces physics-of-failure approaches. It allows manufacturers to use mathematical models and accelerated testing to "see" failures that would take years to appear under normal operating conditions. Ipc-7801 Pdf
