Cobalt in leadfree solder alloys? | 23 October, 2009

We offer SN100C solder alloys. I was asked about SN100E which is tin/copper and cobalt. Anyone know anything about the cobalt and it's pros and cons in soldering process?

We believe that some suppliers replace nickel with cobalt in SN100 to product a shinier, less grainy, more attractive lead-free solder connection.

SN100E sales-types like the idea that it is available in paste, bar stock, and other forms; as compared with SN100C that is not available in as many forms.
