[sdiy] Which solder is safer for home projects ?

[Richie Burnett]

"Mission critical" applications like life support, military, nuclear power and aerospace are exempt from RoHS for reliability reasons (tin whiskers etc.) As is hobby work and R&D provided the end result doesn't get sold into the EU. (Strangely fire protection is not.)

Most board houses have leaded and lead-free assembly lines to support both markets. You'll pay more for a leaded process these days, but the applications where lead is permitted can typically absorb the extra cost.
