Dear fellow process engineers, Some solder joints "trough hole component" have cracked. I suspect that in the market some technician tryed to straighten some components (LED) and has applied enough force to actually brake the joint. The joints were

We have been encountering diminishing ball shear readings these past few weeks, despite the fact that we did not change any ball shear tester parameter. Our reflow parameters are also within spec limits. ( 210-220 deg C max temp. and 40-60 sec dwell
