Use of lead-free solder wire

Use of lead-free solder wire

Solder wire is a fusible metal with a melting point lower than that of the metal to be soldered. When the solder is melted, the surface of the metal to be soldered can be wetted under the condition that the metal is not melted, and an alloy layer is formed at the contact surface to connect the soldered metals together. In general electronic product assembly, tin-lead solder, commonly known as solder wire, is mainly used.

Tin is a metal element, element symbol: Sn, belongs to the main group metal of IVA group, atomic number 50, relative atomic mass 118.71, belongs to IVA group metal, melting point: 231.89 ℃, boiling point: 2260 ℃, density: 7.28g/cm3 . Pure tin is soft, has good ductility at room temperature, stable chemical properties, is not easy to be oxidized, and often maintains a shiny silver luster. The content of tin in the earth's crust is 0.004%, almost all in the form of cassiterite (tin oxide), in addition to a very small amount of tin sulfide minerals.

In the era of online e-commerce, everyone generally buys more or less goods online. If the goods received are exquisite in appearance and carefully packaged, I believe that everyone will feel that the quality of the goods should not be too bad. Similarly, The same is true for the tin wire we purchased. If the finished tin wire is unevenly wound, blackened, and poorly packaged, then you will definitely think about whether the quality of the tin wire is the original tin or not. What about the tin wire of the original manufacturer? In fact, from this point, we also understand the correlation between the appearance of the tin wire and the quality of the solder wire.

While removing the oxide film, the surfactant in the solid solder wire flux also starts to work, which can significantly reduce the surface tension of the liquid solder on the surface of the material to be soldered, and enhance the fluidity and spreading ability of the liquid solder. And ensure that the tin solder can penetrate into every tiny brazing gap. The most suitable temperature for soldering work is the melting point of the solder used +50 degrees.

What is tin-bismuth alloy?

Tin-bismuth alloy is a kind of metal, which is relatively common in our daily life. Its name is called tin-bismuth alloy because its inventor is Babbitt in the United States, and its color is white, so it becomes a tin-bismuth alloy in combination.
Its melting point is relatively low. We all know that the melting point of iron can reach nearly 1,000 degrees, while the maximum temperature of tin-bismuth alloy cannot exceed 100 degrees Celsius when used.

1. The present utility model relates to the technical field of soldering tin bars, in particular to a new type of tin bar.
2. But the tin bars currently used still have the following problems in use:
3. Most of the existing tin bars are covered with plastic film to isolate the air and reduce the oxidation of the outer wall, but the method of covering with plastic film makes it very inconvenient to use, and the film needs to be killed, and the film is torn off without welding. The part that arrives will also be oxidized, resulting in the worse the welding effect of the back of the soldered tin strip, and the torn film cannot be reused, resulting in waste.

Bismuth-tin alloy is mainly a new type of alloy material with low melting point. It can be used as heat-sensitive components such as fuses and fuses in different devices such as solder, fire protection and electrical appliances. It not only has high compatibility and compliance, etc. It also has various advantages such as strong welding strength and accurate melting point, and is widely used in different production fields. So what are the main application areas of bismuth-tin alloys?
1. Casting and mould making.

Tin-containing alloys, including tin-based tin alloys (except tin-lead solder), and alloys with tin as the main additive element, are an important outlet for tin consumption, accounting for about 23% of the total tin consumption. Mainly used in automobile, locomotive, tractor bearing and heavy machine bearing, among which tin-based babbitt is the most widely used.
