How to make enameled wires conductive

Method 1: first heat slightly with fire, then lightly sand with fine sandpaper until shiny

Pay attention to heating with the inner flame of fire

The temperature of the outer flame is too high, and it burns out!

Method 2: Scrape with a knife

Method 3: If it is thicker and harder, use a pair of needle-nose pliers to pinch it back and forth. It only needs to be scraped.

Method 4: Put rosin on the broken end of the enameled wire, and then infiltrate the section into the melting tin of the soldering iron tip. Because the section is not painted, it will be tinned, and the temperature will be transmitted to the enameled wire. The lacquer around the section is not Relying on, it will soon fall off, and soon it will be tinned! The key is three points: stick rosin at the broken end, dip the molten tin in the section, and the temperature of the soldering iron should be higher!

It is more difficult to remove the entire insulating paint, especially from the point of view of ordinary people, there is a simple way, that is, the cross section of the enameled wire can be conductive, and it can be partially conductive by dedicating a short section of insulating skin.

Use a knife to scrape a rough blade (just don't break it). A thin blade is hard to scrape, so use a soldering iron!

Use a lighter to burn, then wipe it with paper, light a small fire, burn on it, and wipe it.
