We see
these all the time, the parts are not stable since the leads are not planar to
the part so the diodes rock. The lead goes under the part and takes the solder
there as well giving you not much wicking up the lead. We have pickup misses as
well from the feeders since the parts tend to tip in the pockets. But not a
defect.

I have attached some pictures of components that always seem to have
one joint that is not soldered as the other end. These happed mainly
with this component at various sites on the board. Is this a
contamination a disturbed joint or a cold joint. This is an SMT process
and the problems vary
on the runs.
I would like to know if this is a defect for class 2 or not.
Thanks in advance for your time.
