Learn what solder is from expert Jeff Koskulics in this Howcast video. Solder is a material that is used to join soft metals, such as copper, gold, and silver. In electronics weâre mostly concerned with copper. Most commonly weâre using eutectic solder, which is a combination of tin and lead. This is eutectic solder, this is 63 percent tin, 37 percent lead, and this is made with a formulation that has a very minimum melting point for this combination of metals. The melting point is somewhere 360 degrees Fahrenheit.
Solder is a metal or metallic alloy used, when melted, to join metallic surfaces together. The most common alloy is some combination of tin and lead. Certain tin-lead alloys have a lower melting point than the parent metals by themselves. The most common alloys used for electronics work are 60/40 and 63/37.
