Fluxus is an international avant-garde group or collective that was founded and flourished in the1960s but still continues today.
The fluxis a chemical cleaner which prepares the hot surfaces for themolten solder. The solder is a low melting point alloy of nonferrous metals. Solder and Flux Solder is a metal or metallic alloy used, when melted, to joinmetallic surfaces together. The most common alloy is somecombination of tin and lead.Certain tin-lead alloys have a lowermelting point than the parent metals by themselves. The mostcommon alloys used for electronics work are 60/40 and 63/37.The chart below shows the dif ferences in melting points of somecommon solder alloys.older and Flux Solder is a metal or metallic alloy used, when melted, to joinmetallic surfaces together.
