What everyone usesSolder wireIn the product, the tin content of the solder wire is15%and99%Between, thenLow-temperature tin wireHow 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. Maybe not everyone has noticed that the ones used in the marketThere is lead-tin wireThere are also some good ones63A certain degree of tin wire. Why?63The desoldering wire is not set65,67,69How about the degree?? Why is there no comparison63The degree is quite good. There's lead-tin wire now?Similar to seventy degrees Seventy-five degrees Eighty degrees, etc.

    In fact, the internal cause is like this.63Tin wire with a relatively low melting point is an excellent blend of lead and tin183℃. But there is no comparison.63The degree is quite good. There are lead-tin wires with a certain degree?Because the price of tin is much higher than that of lead ,63The function of the degree is already quite good. The higher the degree of the tin wire, the more expensive it is, and the tin wire is not even available63The function of the degree is good.

    This kind ofTin wireFor instance, the tin content of low-temperature tin wire is42%Although the actual effect of low-temperature tin wire welding is not very good, it is also because of its melting point138℃In terms of welding, it can effectively prevent some electronic components from being damaged due to excessively high temperatures that they cannot withstand. Because its spot welding is relatively brittle, the basic lead-free tin wire welding is good, but its melting point can reach217℃. This is non-exchangeable and thus has no reference value.

    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.Shenzhen JJY Industrial Technology Co., LTDAfter experiencing12With years of research and development in the soldering industry, choose JJY for soldering. It's worth having for your partners.
