Key measurement metrics defined in IPC-9704 include:
In modern electronics manufacturing, as Printed Circuit Boards (PCBs) become thinner, more densely packed, and subjected to increasingly complex assembly processes, ensuring the mechanical integrity of solder joints is paramount. The standard, often sought in PDF format for engineering libraries, serves as the definitive guideline for measuring mechanical strain on PCBs during manufacturing, testing, and handling.

The IPC/JEDEC-9704A guideline identifies specific high-risk moments where strain gage testing is critical: ipc-9704 pdf
The IPC-9704 PDF is a valuable resource for designers, manufacturers, and inspectors of high-reliability PCBs. The standard provides a comprehensive framework for ensuring the reliability and performance of high-reliability PCBs, and its guidelines and requirements can help to improve reliability, reduce risk, and increase efficiency. By following the guidelines and requirements in the standard, designers and manufacturers can ensure that their PCBs meet high-reliability standards and are less likely to fail.
). Linear gages only measure stress in one direction, whereas a rosette calculates the total principal strain regardless of the bending angle. Placement Rules
Typically placed at the (≥27mm body size) where strain is highest.
