It is illegal to produce boards with lead, just check the internet on
RoHS. It is allowed in military applications and some medical devices
as reliability is lower.
I think it's perfectly legal to rework boards using lead/tin solder if
the boards were originally produced with it and because of that you can
still buy led/tin rosin fluxed solder.
