Moje Amerikáňská Bible (ASM Handbook Volume 6 - Welding, Brazing and Soldering) říká o bismutových pájkách tohle:
Bismuth-containing alloys are also referred to as "fusible" solders. They are used on heat-sensitive devices or in step soldering processes. Upon solidification, bismuth-containing alloys exhibit either limited contraction or expansion, as in the case of solders with more than 47 wt% Bi (Ref 5). These alloys are prone to moderate oxidation in both the liquid and solid states, and they exhibit some difficulty in wetting because of limited flux activity at the lower working temperatures. These alloys have good mechanical properties and are used very successfully in a number of electronic applications
Nějakou specifickou sekci o bismuthových pájkách jsem tam asi úplně nenašel, ale ono to má 2873 stránek
