What is Melting Range
Melting range is the temperature range at which a solder alloy undergoes a phase transition from a solid state to a liquid state. It signifies the temperature range within which the solder alloy begins to melt and completely transforms into a liquid.
The melting range of a solder alloy is determined by its composition, with different compositions exhibiting different melting ranges. The presence of additional elements can also impact the melting temperature of the solder alloy. For instance, additives like Bismuth and Indium are often used to lower the melting point of solder alloys, enabling the use of low-temperature solders suitable for bonding heat-sensitive components to PCBs.
