Hey guys, bit of an odd question. I want to solder to a piece of pure silver ~99% in some way that I can interface with an IC. So perhaps go from silver to silver solder to a pcb pad. From what I can see, silver solder melts at around ~700 C so I'm guessing a conventional electronics soldering iron wouldn't be able to get hot enough. Is the only way to do this with a blow torch? Can silver solder chemically form bonds with copper or Sn/Pb solder? If I need to get to ~700C to melt the silver solder with the PCB pad, would it damage the PCB?

Silver will definitely solder with regular solder, and will easily solder to a PCB using regular electronics solders. Just be aware you will need a lot of heat if the silver mass is large. No need for any exotic silver laden solder, it will dissolve in the regular solder quite easily at the regular tin solder melting point. Just use a bit of flux to improve wetting and clean well afterwards. Do not use acid or borax based flux, it will eat the copper traces, but 5o solder a coin to a PCB just regular solder and hot air to get the coin to solder melting works fine.
