• Attach strain gauges to specific locations on a populated PCB (usually near large BGAs or ceramic capacitors).
• Calibrate the equipment to measure microstrain (με).
• Capture data during a specific event (e.g., a single board separation from a panel).
• Compare results against established pass/fail criteria.

Test conditions and variables

With the industry's shift to lead-free solder (RoHS compliance), the reliability characteristics of solder joints changed. IPC-9704 provides the data and methods needed to qualify these new materials, ensuring that lead-free joints can withstand thermal cycling without failing prematurely. ipc-9704 pdf
