In the maintenance of electrical appliances, we often encounter the problem of tin on the electromagnetic aluminum wire, such as the broken welding of small choke coils and small inductance coils and mid-peripheral transformers.
In actual operation, it feels more difficult. This is because the enamelled aluminum wire used by these components is very thin, and the conventional "knife-scratch fire" method is used. Therefore, it is very easy to burn or scrape the wire end and cause repair failure.
ZTELEC has mastered a set of methods of tin on round aluminum enameled wires through experiments, so now it is introduced as follows.
First find a piece of clean flat glass, and then a small amount of rosin needs to be clean and new, but it has not been welded and sintered, or alcohol rosin liquid.
Then melt or paint on the glass plate and apply the tinned enameled aluminum wire to the rosin, and then press the wire with the soldering iron tip, then scrape along the wire. At this time, the enameled wire The paint film is removed and plated with tin.
Then turn the end of the electromagnetic aluminum wire half a turn to turn the untinned side up. Use a soldering iron tip to lightly scrape such a shiny wire end and it will be hot.
