How Do You Make An Electrical Solder Connection?
Soldering is an art and it takes practice. Soldering uses melted metal to glue two pieces of metal together to form an electrical connection. A good solder joint results when the solder properly glues, or wets, the two surfaces that are to be joined together. When properly heated, the solder should flow almost like water. Ensure that the surfaces to be joined are clean. Heat and clean the soldering iron. The iron should have a thin coat of solder on the tip (typically referred to as tip tinning). Over time, the tip becomes oxidized and turns a bit dull. Wiping the hot iron on a damp sponge removes the oxide. Electrical applications use 60/40 solder (60 percent tin and 40 percent lead). Most electronic 60/40 solder has a rosin flux core. If the solder doesn’t have a flux core, a flux paste is required. Bring together the pieces to be joined. Apply the solder iron to the joint quickly (this avoids overheating the work piece). The desired effect is that it should heat it up fast–in about
