Lead free solder for SMD

[spargo]

I'm looking to try some lead-free solder, specifically for surface mount components, but through hole as well.  There are 50 different mixtures of metals, and approximately 5,000 types of fluxes it seems.  Does anyone have recommendations for lead free solder of a thickness of 0.02" or below?  I already have liquid flux needed to supplement.  I've researched quite a bit, but just wondering what others have experience using.

Also, I've heard the fumes of lead free solder can be worse than leaded solder.  Does anyone have recommendations for ventilation?  Or any other tips on the subject?

Well yeah , they say lead free solder fumes might be worser then 60/40 , well ,
you don't have a DIY extractor yet ? TTG has a guide on a simple one ._.

Lead-free fumes certainly smell worse to me. Extractor highly recommended.
Also keep in mind that lead-free requires a higher temperature to melt, your iron will need to be typically about 100° hotter than when working with leaded solder.
In my experience, lead-free is a little harder to work with and does not flow quite as readily as leaded solder.

3) All of the joints do not turn out shiny , so its a PITA . 4) 450C is the minimum for it to flow easily . .
