The trick with the Ag-Cu hard solder and bell repair is to use either acetylene-air or MAPP-air for heat. Oxyacetylene is too hot (will burn silver plating right off or melt/burn brass) and propane-air isn't hot enough.

The lead-free Sn alloys still have problems in the electronics industry. While the leadless alloy "drop-in" replacements for Sn-Pb are getting better, theý're still not quite there yet. One big problem is the flow temp range and wetting action.
