How about conductive glue replacing solder?
Na, will have to wait until the first EU politician's cellphone fails in

What ever happened to 'multiwire' (or some such trade name)? It was
a multilayered weld-bonded wiring alternative to multilayer PCBs
in the '60s and '70s and was very rugged, easily implemented with
NC technology, and used no solder of course.

Since each layer is built up in succession, between power and ground
planes, even BGAs can be accomodated.
