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.
Traditional solder that used to be used for soldering in the electronics industry used to be a mixture of tin and lead. Different types of solder are used for different purposes. Solder is of course used in plumbing. The type of solder used for electronics usually contains 60% tin and 40% lead.This is often known as 60/40 solder. It is what is termed a Eutectic Mixture. Although this is a chemical term, basically this type of mixture melts at a temperature well below that which might normally be expected.older is of course used in plumbing.
