Material components of soldering iron tip
The main tool for electronic soldering is the electric soldering iron. Commonly used are internal heating type and external heating type. There are also temperature-adjustable and constant-temperature soldering stations, and soldering irons specially used for disassembling electronic components. Most of them are indispensable when it comes to welding. The basic function of turning on the soldering iron tip is to provide heat to the solder (usually tin wire) through its own heat conduction to melt it, thereby welding the two workpieces. It seems to be a very simple thing, but it needs to heat up quickly and is often used. It has the characteristics of withstanding high temperature, corrosion resistance, smooth welding and long service life. The key to how to do it is to look at its main material composition and you will know.
First of all, the soldering tip is not composed of a single metal. It is composed of five brothers: copper, iron, tweezers, chromium, and tin.
The boss is copper
Copper, as a heat conductor, is the main component of the soldering iron tip. Accounting for about 85% of the soldering iron tip material, copper has good thermal conductivity, which is conducive to the rapid heating of the soldering iron tip. Good soldering iron tips are made of copper, but some manufacturers use brass. In order to reduce costs, it also reduces the cost of the soldering iron. The thermal conductivity of the head.
dick iron
Iron mainly plays an anti-corrosion role in the soldering iron tip and is a key factor affecting the service life of the soldering iron tip. The crystal structure of the iron plating layer of a good soldering iron tip is fine and dense, and it has good corrosion resistance. Such a soldering iron tip has a long service life and good tin removal effect. Manufacturers with poor iron plating technology mainly rely on the thickness of the iron plating layer to control the service life of the soldering iron tip. Usually, if the iron plating layer is thick, the tip will not be tinned, and if it is thin, it will not be durable.
old nickel
The function of the tweezers on the soldering iron tip is to prevent the iron coating from rusting and facilitate subsequent chrome plating.
old four chrome
Chromium does not stick to tin, preventing tin from running onto the tip handle during use. Generally, the chromium plating time of soldering iron tip is more than 5 minutes, and the ordinary decorative chrome plating time is about 1 minute.
old five tin
The tin is on the head, which is where the tin sticks during use.
To form a qualified soldering tip, these five brothers are indispensable.
