. According to the IPC standard, non-wetting is defined as the inability of molten solder to form a metallic bond with the base metal. This results in the PCB pads or the

. •  The surface energy of the copper must exceed the surface energy of the solder for wetting to happen •  This is defined as non-wetting and de-wetting

. •  Temperature and heat are related but there not the SAME. –  Example: A soldering iron is set at 600oF and is hotter than a flowing river at 40oF but the river has more joules of heat energy, sometimes defined as “Q

. Alloys are called eutectic when the solidus and liquidus are equal. While wetting begins at the solidus temperature, best wetting is achieved at a peak temperature 15º
