The IPC/JEDEC-9704 standard establishes methodologies for measuring mechanical strain on PCBs during assembly, test, and handling to prevent failures like solder joint fracture and pad cratering. It requires identifying high-risk processes, such as SMT and press-fit insertion, and placing strain gages within 5mm of critical components.

The Verdict: Engineers compare these readings against the limits defined in IPC-9704. If the strain is too high, the process is "illegal" according to quality standards and must be redesigned. The Evolution: IPC-9704A ipc-9704 pdf

In modern electronics manufacturing, the push for miniaturisation has led to thinner PCBs and denser component packaging, such as Ball Grid Arrays (BGAs). While these advancements improve performance, they also make assemblies highly susceptible to mechanical damage from board flexure. Obtain the full IPC-9704 standard document for exact

The IPC-9704 standard provides several benefits to designers, manufacturers, and inspectors of high-reliability PCBs. Some of the benefits include: For a complete reliability program, these two standards

In short, IPC-9704 is the difference between a product that lasts for years and one that fails because of a single, invisible bend.
