Among the Solder wire products everyone uses, the tin content of the Solder Wire ranges between 15% and 99%. Then, for Low-temperature tin wire, how much tin should be appropriate? Shenzhen JJY gives its partners an example:

First, understand that low-temperature tin wire can be divided into two types: leaded and lead-free. Perhaps not everyone has noticed that There is lead-tin wire, the type commonly used in the market, also includes some good 63% tin wire. Why is the desoldering wire not set at 65, 67, or 69 degrees? Why is there no lead-tin wire with a tin content higher than 63 that is as good? Now there are lead-tin wires of around seventy, seventy-five, eighty degrees, and so on.

In fact, the reason is this: 63 tin wire, with its relatively low melting point, is an excellent blend of lead and tin at 183 ℃. But there is no lead-tin wire with a tin content higher than 63 that performs as well. Because the price of tin is much higher than that of lead, the performance of 63 tin wire is already quite good. The higher the tin content of the tin wire, the more expensive it is, and the tin wire does not even perform as well as 63 tin wire.

Take this kind of Tin wire as an example: the tin content of low-temperature tin wire is 42%. Although the actual soldering effect of low-temperature tin wire is not very good, because of its 138 ℃ melting point it can effectively prevent some electronic components from being damaged by excessively high temperatures they cannot withstand. Because its solder joints are relatively brittle, ordinary lead-free tin wire soldering is better, but its melting point can reach 217 ℃. The two are not interchangeable and thus have no reference value for each other.

To sum up, the amount of tin does not determine the actual soldering effect of the tin bar. Only by choosing the appropriate tin bar can it be considered a good tin wire.
