I have a large lot of circuit boards where about 20% have small, hairline
solder fractures around some wave soldered PTH connector joints. We're
working on root cause analysis to prevent it from happening and repairing
the boards which have failed inspection. But, we're tying to figure out
what to do with the boards that have passed the inspection but may be at
risk. Quick and dirty tests have been unable to create fractures on these
joints and they pass visual criteria. Are there any quantitative tests
that could be performed on a sample to verify solder joint integrity? We
don't hae any historical data for comparison.

Thanks! Cheryl
