It's already 2021. Aren't there any cheap and good tin wires? JJY solder Paste Manufacturer tells you

all2021It's been a year, and there's nothing cheap and good to useTin wire??If you want to purchase tin wire nowadays, how to choose it? This question, if it were in the past, probably wouldn't have been a problem because many electronic products and industrial goods must use this kind of auxiliary equipment to complete their tasks. Nowadays, it has also entered the era of2021In recent years, there are more and more brands and suppliers to choose from. How do people usually make their choices? Let's discuss it together below:

Everyone knows tin wire It is divided into leaded tin wire and lead-free tin wire. But have you noticed that among the leaded tin wires we use, the best one is only63De-tin wire. Except for this one63Except for the tin wire, the degrees of all other tin wires are the same5A multiple of. Why?63The tin wire is not set to65What about the degree? Why is there no ratio?63Leaded tin wire with a higher degree And? For example70Degree of ,75Degree of ,80Degree, etc. In fact, the truth is like this:63The tin wire of a certain degree is the best ratio of lead to tin, and its melting point reaches the lowest183℃. And why is there no comparison63What about lead-tin wires with higher degrees? This problem is much simpler because the price of tin is much higher than that of lead.63The degree is already so good. The higher-grade tin wire is not only expensive but also not available63It's really useful.

  ForLead-free tin wireThe most commonly used one is the tin content99.3%copper0.7%There are tin wires, and others include silver-containing tin wires, low-temperature tin wires, etc. These tin wires are all produced and developed to achieve effects that conventional lead-free tin wires cannot. For example, for low-temperature tin wire, the tin content of low-temperature tin wire is42%Although the soldering effect of low-temperature tin wire is not very good, due to its melting point being only138℃In welding, it can prevent certain components from being burned out due to their inability to withstand high temperatures. However, the solder joints of its welding are relatively brittle. Conventional lead-free tin wire welding works well, but its melting point is as high as possible217℃. This is irreplaceable and thus has no comparability.
