Lead free solder is a regulatory thing for commercial manufactures.

Most repair techs use lead solder, just better to use.

We switched to lead free where I work almost a decade ago, these days I only ever use tin/lead if I am working on valve equipment.
Once you get used to it the modern lead free solder is just as easy to use as tin/lead and a lot less toxic!
