Till late 2003, RCA was using hot glue to secure heavy parts and got
bitten back because the heat and vibration (even 15.7KHz will) made
hot melt glue slide through the lead and the solder breaking the
solder bond.

Was used from before CTC169 all the way to few ATC113 then RCA
smartened up and quit using it.

Sneaky.

Only, and only two ways: Do nothing with glue anything using good
design practices or use silicone glue.
