Rongjun,
If Werner Engelmaier were still alive he would shake his finger at you!  :)

Solder joint strength is not necessarily a sign of a reliable joint. It might or might not mean that a joint is well made but not say much about reliability.  For instance Ericsson (I believe) found that small (lower shear strength) solder joints for chip components were actually better because they were more ductile.

That is why you will never find an official published list of pass/fail solder joint strengths.

Subject: [TN] Component solder reliability

Hi Experts:



Is there have an industry standard for component pull/push test? What is standard value for each component?
