Todd,
From what I have generated, as a generic number you may expect something
like 1-2.5Kg, depending on solder alloy/type, component standoff, and
pad/fillet geometry etc.
These numbers are for shearing against the body of the component [aka -
the shear tool contacts both terminations during shear]
Height of the shear tool during shear can also play a significant roll
as too low a height shears the solder [giving a greater shear value],
and too high somewhat rolls the component out of the solder [giving a
lesser value].
Hope this helps a bit. I would be interested to know if there is a
standard for this procedure - specifically for SMD's, that is.
Steve

Subject: [TN] SMD Capacitor Shear Strength
I have a question for the oracle . . .
Does anyone know what is the solder joint shear strength for an 0603
capacitor (assuming standard eutectic solder)?
