Here's two more cents... Susan may be referring to pins that are made with
a retention feature that hold it in the board while soldering. True
pressfit-type pins never require soldering unless there was a mistake made
in the hole size during PWB fabrication (hole too large). To repeat, the
first step is to review the part spec.
