Latest Patents

Douglas J McIsaac holds a patent for "Variable melting point solders and brazes." This invention involves compositions that comprise a metal or metal alloy powder with a low melting point combined with a metal powder that has a higher melting point. Upon heating, in-situ alloying occurs between the two powders, resulting in solidification at the solder or braze temperature. This process creates a new, higher solidus temperature with minimal intermetallic formation. For instance, a solder made from Sn powder mixed with a Sn–Bi eutectic powder has an initial melting point of 140°C and a re-melt temperature of 220°C after heating due to in-situ alloying.
