Solder is a nice woody word, even though it contains tin. And for even more irony (and silvery), there is a new solder that contains iron and silver, and eliminates lead.
Magnetic solders are a leap towards green alternatives
By subjecting the solder to an alternating magnetic field, the solder can be selectively heated. This keeps surrounding materials at safe temperatures while melting only the solder itself.

[A]n external magnetic field can be used to remotely manipulate the solder, so it can be moved into hard-to-reach places, such as narrow vertical channels. This means that broken connections within devices can be “self-healed” by applying a magnetic field to melt the solder and attach the ends together.
The LHC used a Green leadless solder on every one of its supercon magnet busbar shunts. How well did that work out? Corrosion. Exotic solder joins are renowned for intermetallic surprises down the line. Gold metalization gets “purple pest.” Tell us how silver solder plus nano-iron is cheaper than lead-tin.
