How To Solder Copper Wire
Hence it flows upwards as well.
How to solder copper wire. The best solder to use for tinning stranded copper wire is electrical-grade rosin-core solder. Touch the tip of the soldering iron to the copper wires. This is known as capillary action when a liquid flows inside narrow spaces by taking no help from any external forces.
A jumper is a stiff sometimes bare wire that bridges across some traces on the top or bottom of the board. Heat until you see the solder flow into the joint. Solder the wire to the jumper using a moderate amount of solder.
Apply the tip of the soldering iron to the wet sponge to make the tip clean. Whilst waiting for the iron to heat take a sponge soak it in some cold water and wring it out so that it is damp. The problem was that the aluminum connections expanded and contracted much greater than copper.
Keep the iron in place and touch the solder to the wire until its fully coated. Aluminum wire became popular in the 1970s because it conducts electricity well and is less expensive than copper. Let part cool until warm then wipe off excessive flux with soap and water.
Then remove heat source. Tap the end of the 6337 solder on top of the wire splice so the solder melts down into the wires. Make sure the pieces to be soldered together are VERY clean.
Strip off about 1 inch of the insulation from each end of the two wires using the wire strippers. This is an acid-free solder that contains a flux in the core of the solder. To make it a little easier to start here are a few tips.
