I'm new to soldering, does the type of soldering/flux matter? Heat? Any other variables that I should know about before attempting this? I picked up a soldering gun today but haven't talked myself into opening the package yet... Weller SP40NK. Comes with a tiny coil of lead-free solder... Any advice appreciated...
 
And to those who would advise me be not to this... I appreciate your advice, but probably wont take it
