What Is A Solder Alloy's 'Liquidus'?

  • Solder Alloys

  • The liquidus of an alloy is the temperature above which the alloy is completely liquid. In this phase there are no more solid phases within the alloy so it is completely molten. The liquidus temperature is dependent on the composition of the alloy. Changing the composition can change the liquidus temperature.
