Could you briefly discuss the differences between solder wire and silver wire?

Everyone is relatively clear about itSolder wireIt is a necessary material for connecting electronic components, and it has many names, such as tin wire, tin thread, etc. Solder is mainly used in various electronic soldering processes, including manual soldering, wave soldering, reflow soldering, etc. Now let's talk about silver wire, which is a chemical substance with the molecular formulaAgIt is a white and lustrous metal with a face-centered cubic structure and is an excellent conductor of heat and electricity. It does not react with water and oxygen in the atmosphere, and turns black when encountering ozone, hydrogen sulfide and sulfur. It is inert to most acids and can quickly dissolve in dilute nitric acid and hot concentrated sulfuric acid. Hydrochloric acid can corrode its surface. It dissolves in molten hydroxide alkali, peroxide alkali and cyanide alkali in the air or in the presence of oxygen. Most silver salts are sensitive to light and insoluble in many acids. Now, the solder paste manufacturer will briefly discuss two differences:

From the above concepts of tin wire and silver wire, we can roughly know that tin wire and silver wire are actually two different types of substances. Their differences mainly lie in the following aspects:

1Different colors: Tin wire has a slightly bluish white luster, while lead-free tin wire may have a yellowish tint. The color of the silver thread is pure white. 

2Different melting points: The melting point of tin is 183-227℃It is very low compared to silver threads. And the melting point of the silver wire960℃(lit.)Much higher than tin wire.

3The hardness is different: Tin wire has a low hardness and can be easily broken after being folded by hand a few times. Compared with tin wire, silver wire is harder and less likely to break. 

4Different uses: Tin wire is mainly used for soldering the solder joints of electronic products and post-soldering processing, etc; Silver is a very small trace element in the process of manufacturing tin wire. Its main uses include gifts, jewelry, handicrafts, and the electronics industry, etc.

The above are the differences between these two situations that we have introduced to you. It is convenient for you to take a look. Do not make mistakes in matching different products, as this will also result in poor quality.
