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.
Flux paste is a cleaner and corrosivepaste to work with copper and other metals to help the solder attach to the other two pieces that your soldering.Source(s): 20+ yrs in bldg maint field.older flux deos a couple things, it helps keep the guns element clean and it helps the solder bond to the part in question. You can buy rosin core solder with the flux already inside the solder, this is much easier to use then to use solder flux.
