How long does it take to apply for the electrician IC certificate in Chashan, Dongguan in 2016? Are there any good training institutions?

When welding, first put an appropriate amount of solder on the blade of the soldering iron, and then accurately contact the blade of the soldering iron with the solder joint within the time limit. After the solder joint is formed, remove the soldering iron quickly. For this welding method, the amount of tin on the soldering iron should be just enough for one solder joint. If there is too much tin, the solder joint will be too big. If there is too little tin, the soldering amount of the solder joint will not be enough. When welding with this method, the solder joints must be coated with flux, otherwise the solder joints may not be covered with tin. Because when tin is hung, most of the flux (rosin) in the welding wire volatilizes during the tin hanging process.

The spot tin welding method is also called two-hand When welding, hold the soldering iron in your right hand and hold the soldering wire in your left hand. Both hands must cooperate and coordinate with each other during welding. Not only that, but you also need to master the correct operating methods and welding essentials, so that the solder joints can be bright, smooth, and uniform in size, and eliminate false welding and false welding. This welding method has the characteristics of fast welding speed and high solder joint quality. It is suitable for rapid welding of multiple components. The specific welding process can be divided into the following <> steps.
