[BC] the solder I'm using

[David Reaves]

IIRC, "eutectic" is the term for the exact mixture percentage of two  
or more metals that yields the lowest melting temperature. I also  
recall that, typically, the eutectic temperature can be considerably  
lower than that of either of the elements alone.
