I think most of us can agree that hot gluing your PWMs is not an elegant solution. We can put this aside and focus on whether it's really a practice that can cause equipment damage.

This particular concern sounds silly. Your standard 99.3Sn-0.7Cu lead-free solder
melts at ~440 F (PDF link). Eutectic 63Sn-37Pb solder melts at 361 F. Low-temperature "hot melt" glue guns
range from 170 - 250 F.
