Lead Free Solder Recommendations Answered

Hello, I am going to be working on some electronics projects soon and was wondering if anyone had recommendations for lead-free solder. Some completed projects are going to be shipped to the EU, California and New York so I need to start paying attention to RoHS standards. I was hoping to get pointed in some sort of direction to avoid buying a dozen different kinds and figuring it out myself. Any advice would be greatly appreciated. Knowledge regarding previous experience with lead-free solder and electronics would be awesome. Thanks in advance.

I wouldn't worry about it. Most solder contains around only 15% lead. Its not that big of an issue

Huh? Most solder is 37 to 40% lead. But I don't think that non-commercial projects are required to follow RoHS, and the general wisdom seems to be that hobbyists should just continue to use lead-based solders.

I think you have it backward. Antimony hardened lead compounds are usually something like 95% lead and 5% antimony. (I think there are tin/antimony solders for plumbing, as well, but they usually don't have a melting point compatible with electronics.)

ok, 95% tin, 5% antimony. Yes, it was plumbing solder

I'm wondering about this too, cause if i sell kits or premade electronics this summer online (home made, but I'm going to be making a lot) am I aloud to use solder with lead in it?

. I'd play it safe and use Pb-free (RoHS-certified if you plan on selling to Europe). Even if it's legal now (I don't know if it is or not), that's liable to change next month.

. IMNSHO, Kester makes the best lead-based solder for hobbyists. I haven't tried any of them, but their [http://www.kester.com/en-us//products/prodcat_results.aspx?ind=-1&pt=-1&chem=-1&lf=Y lead-free products] should meet your needs.
