Eutectic vs. Non-eutectic Solder Alloys

Every alloy has both a solidus and a liquidus melting temperature. The solidus temperature is the point when the alloy just starts to melt. ...

What is an Alloy?

An alloy is comprised of two or more metals. These metals are stable and have some level of solubility together; otherwise, they would not form ...

The liquidus of an alloy is the temperature above which the alloy is completely liquid....

The solidus of a solder alloy is the temperature above which the alloy begins to melt, and, below which is completely solid....

Let's explore solder alloy elemental solubility....
