Default Soldering temperature for PCB?

I just purchased an adjustable heat soldering station and wondered what heat I should use when doing cap replacement etc. on circuit boards. I've had trouble in the past with the cheap irons that I bought from Radio Shack on the thin PCB's in Sony and Philips DVD players lifting and vaporizing traces. Part of it was my inept solderng skills but the iron was a problem too.
The soldering station has a working temperature of 392-896 deg F. Recommendations?

Thank you!

Jim

Something like 400C and a clean soldering tip can do wonders.
Oops, I see you are talking F and thought you couldn't go lower then 392C. Now, 392F = 200C so try something like 570F to start with.

Has the USA gone to lead-free solder yet? The rest of the world is going that way but the USA doesn't see to sign environmental accords. The melting point of Pb/SN is 183C (361F) Whereas Lead free is more like 210 C (410F) .

When i replace elkos
i first pull the case from the pcb
just push the case sideways this will disconnect the pins from the alu.foil
Nou you can easally desolder the remaining pins wich are much more easy to heat up.

This will work with the normal coaxial versions. But not the really large ones.

Regards
Simon
