Introduction In the high-stakes world of electronics manufacturing, reliability is everything. One of the leading causes of latent field failures in printed circuit assemblies (PCAs) is not a component defect, but mechanical stress—specifically, strain induced during assembly, test, or board separation processes. ipc-9704 pdf

The router was causing 3,000 µε (double the IPC limit). By slowing the routing speed by 40% (per IPC-9704 guidance), they reduced strain to 800 µε. Failure rate dropped to 0.1%. Conclusion The IPC-9704 PDF is not just another technical document; it is the blueprint for mechanical reliability in modern PCB assembly. Whether you are setting up a new SMT line or troubleshooting field failures, this standard provides the measurement methodology and numerical limits to protect your solder joints.
