Susan, The only place I have seen it to be acceptably done was on page #20
of J-STD-001 (or similar method). I have seen other things, but they were
mostly too horrible to describe.

Subject: [TN] ASSY: PTH -> SMT

Lately I have been seeing failure analysis that indicates the failures
were caused by trying to take a through hole component and bending
the leads up and around or under the component body to make it
a surface mount component.  In one case a crystal seal was broken
and another the bends were just too "springy".

Is there a set of suggestions as to how and when and IF this can be
done to a through hole component?
