[Elecraft] Soldering temperature

[Don Wilhelm]

  David,

Assuming a 2 lead component --
I would use 750 to 800 deg F to remove the component - heat each end 
alternately until it moves and then "flick" it away from its solder pads.

When installing the new component, 650 to 700 deg F should be adequate, 
but that depends on the solder - if you are using lead-free solder, you 
will have to increase those temperatures.  The soldering of any one 
connection should be complete in 2 to 3 seconds, if it takes longer than 
that, the soldering temperature is too low, but if it takes less than 2 
seconds for the solder to flow, the iron is too hot.

73,
