[Elecraft] Heat sinks?

[Mike WA8BXN]

Back in the days when those tiny devices started to replace things that glow
 when we were using those 100 watt irons or guns, they sure did make it
clear you better you better clip a heat sink between the device and where
you were soldering. Seems over the years the devices have improved a bit,
and out irons have cooled down. So its rare these days that heat sinks are
needed. You should be fine applying heat for a moderate amount of time. Don
t be so quick you get cold solder joints!
