In my previous question I focused on lead-based solder alloys (see Best solder wire - Sn63Pb37 vs Sn60Pb40 vs ...?).

Some of you brought new exciting solder alloys to my attention. The two most promising types contain either Bismuth or Indium.

Some questions:

  • How do they compare to each other on properties like:

    • wetting of pads and pins
    • interaction with fluxes
    • joint strength - brittleness (is this directly related to the "tensile strength (PSI)" column in the table below? Please enlighten me.)
    • price
    • ...

  • How do they compare to standard solder alloys, like Sn60Pb40?

  • Any drawbacks?

  • Most of them are sold without flux core. Wouldn't that make the solder process very difficult?

  • What kind of flux should one use with Bismuth and/or Indium based solders?

Note:

Perhaps the following table might be of help:
