Let's briefly discuss what the functions of lead-free solder wire are?

Since the2020Since the Spring Festival of last year, the novel coronavirus has been completely integrated into our lives. Under such a severe situation of the epidemic, various prevention and control areas across the country and many products have been unable to be delivered. Many people are very worried about this. Now I would like to tell you all about itSolder wireWhat is its function? Solder wire is not used for conducting electricity. No matter how good the solder wire you use is, its conductivity is not as high as that of an ordinary copper wire. For instance: I bought a containing3%Silver, but don't forget there is still97%Tin. You can't deny this, can you?

Perhaps you will say that the ones you bought before were of good quality63%Tin and37%Lead has a low melting point (low current), is easy to weld, has low requirements for tools, and its price is also low. Yes, I admit that these are all its advantages, but it is not environmentally friendly. Moreover, its low melting point tolerance makes its strength worse.
If you stay at this point, you are out of date. Nowadays, everyone is using the newly released environmentally friendly solder wire. Although it is generally tin-copper, lead-free tin wire or solder wire (XHT-SnAg3.0It has a high melting point and high requirements for tools, which increases the working cost invisibly. You might say again that it has high metal strength and can withstand high current, but it is non-toxic and environmentally friendly. In my opinion, this is the most important point.
Of course, there's even better. I won't waste words on any more. I only wrote "containing silver" above3% . For more details, you can visit the official website of JJY.
One more point, one of the standards for solder wire is strength. We should understand that the main function of solder wire is to fill and fix. Although silver has the best electrical conductivity, followed by copper, this only proves that you haven't used pure silver solder wire. The melting point of pure silver is960.5°So it wasn't used for conducting electricity. I only found out about it a long time later.

In the end, I still hope that the COVID-19 pandemic will end soon and restore us a peaceful, stable and harmonious living environment!
