Not true. I am an electronics manufacturing engineer. Data coming in shows SAC (no-lead) alloys to be worse than SnPb under shock and vibration. (Don't drop your SB3.) About the same as SnPb under thermal cycling. The real issue is the false belief that the lead free alloys are better for the environment. Also not true when looked at from a scientific and not a political/marketing point of view. Here is some reading for you: www.rohsusa.com Even the US EPA agrees that lead based solders have no adverse impact on the environment. This is what happens when politicians get involved in technical matters. We now mine more tin (which produces lead as a by product), we use more energy to solder at 40 degree C higher temperatures, we throw away 50+ years of soldering knowledge and reliability for an unknown alloy and actually put worse things in the landfill. Go figure. Recycling is the answer.
