For special-shaped solder wire, use a thermometer to measure the temperature of the soldering iron tip before welding. The soldering process of lead-free tin wire should be as short as possible to avoid damage to the circuit board; and the flux should be able to solder all types of circuit boards and components. The special-shaped solder wire usually needs to be used in conjunction with an electric soldering iron, so the use of the electric soldering iron also has a certain impact on the welding quality of the solder wire. When setting the temperature of the soldering iron tip, it is necessary to consider the heat resistance and safety of electronic components, so as to prevent the circuit board and components from being burnt by the temperature is too high. In fact, a constant temperature electric soldering iron can be used to make the welding of the solder wire continuous and durable, and it can also make the welding of the solder wire more efficient and quality.

Tips for buying special-shaped solder wire

What level of solder wire should be selected according to the object to be soldered. The level of solder wire is the content of tin and lead in it. Different content determines the quality of the solder wire. When purchasing solder wire, you need to pay attention to the packaging. Even if the packaging is exquisite, it does not prove that the quality of the solder wire is good. Any solder wire produced by regular manufacturers will have the manufacturer's logo on it. If there is a quality problem, you can find the manufacturer to replace it. Adjust the temperature of the soldering iron tip to the melting point of the solder wire, which can be slightly higher. The contact time between the soldering iron head and the contact point should be within 2-5 seconds. If the time is too short, the solder wire does not melt at all. Too much melting of the wire will burn the pins to be soldered, so master the correct soldering skills to solder beautiful and high-quality solder joints. Can be purchased directly from the manufacturer. If you want to be cheap, people often buy solder wire in the nearby electronic city, and these dealers will definitely raise the price to earn the difference, so we can go directly to the manufacturer to order, and we can actually see to the quality of the solder wire produced by the manufacturer. When soldering the solder wire, pay attention to the temperature of the soldering iron tip. It is ideal to use a constant temperature electric soldering iron. It is also necessary to determine whether the shape and size of the soldering iron tip are suitable.

Special-shaped solder wire welding characteristics, after the metal composition of the special-shaped solder wire is determined, the quality of the flux inside the solder wire determines the welding quality and welding efficiency of the solder wire. If you use a slightly hotter tip, the solder wire residue should not burn or darken. The flux should not splatter or produce a lot of smoke when soldering. If the flux is washable cored solder, it should be easy to remove with hot water. The flux of the solder wire must also be active enough and remain active enough when in contact with the tip of the soldering iron. In the case of no-clean flux, the post-soldering residue must be non-toxic and non-hazardous.

Tips for buying special-shaped solder wire, lead-free solder wire is a product that solder manufacturers will definitely produce, and there are many solder manufacturers, so the quality of the solder wire produced is naturally different. So people in the electronics industry need to pay attention to some skills when choosing high-quality solder wire.
