If one can manage to make a slight bend to all pins before inserting
the IC then the cycles of thermal expansion and contraction won't
stress the IC's internal connections as much as a straight pin would.
Some IC's already come with the pins already pre-bent for this reason.

LC Actually, the reason to attach devices to the heat sink before
LC soldering is to avoid stress on the solder connections at the pins.
LC You are soldering ICs, not pipe. If the IC is getting hot enough to
LC need the heat sink from soldering, you need to get some lessons in
LC soldering technique, especially on an output IC.
