What are the pros of molten solder？
A

Solder is diffusion boded and isn’t peeled of, which means that it is appropriate for strong bending.

It is possible to make stripe pattern without masking and rare to cause whisker formation.

Also, solder powder doesn’t spread a lot in pressing, so there are cases in which you don’t need to use a dust collector.
