The main solder raw materials in the solder industry include
solder wire, solder bar and solder paste. According to different production processes, solder wire can be divided into solid core solder wire and rosin solder wire. In the previous article, we have also popularized solid core solder wire and solder wire. The knowledge of rosin solder wire, so what are the characteristics of solid core solder wire, how to distinguish it from rosin solder wire, today we have collected some information for everyone to analyze as follows:
First of all, the characteristics of solid core solder wire are summarized as follows:
1. Compared with rosin solder wire, the storage time of solid core solder wire is longer, and there is no worry about the volatilization of flux components in solder wire, and it also reduces the oxidation of solder wire.
2. Solid core solder wire can be used with different types of flux at will to achieve welding between different materials.
3. There is no smoke generated during welding with solid core solder wire, and there is no need to worry about the problem of tin spatter.
4. The efficiency of solid core solder wire is relatively slow during welding, so the selection of flux should pay special attention to its quality.
5. Solid core solder wire is mostly used in some special products, which cannot be cleaned, and there is no welding process with smoke during welding.
6. The process of solid core solder wire welding is also more complicated. First, flux is applied, and at the same time, a soldering iron tip is used to melt the solder wire. The process is limited, and the welding efficiency is not as good as that of rosin core solder wire.
7. When welding the solid core solder wire, it is necessary to adjust its temperature according to the composition of the solder wire.
At present, due to the advancement of production technology and technology, the requirements for production efficiency are getting higher and higher. Solid solder wire is slowly being replaced by rosin solder wire. Rosin solder wire does not need additional flux when used, and is used for many In this kind of working environment, the size of rosin can be adjusted according to machine welding and manual welding welding process during welding, which greatly improves the efficiency of production. Generally speaking, rosin solder wire is easier to weld than solid one.
Secondly, the distinction between solid core solder wire and rosin solder wire is still very easy to distinguish. First, get the solder wire and look at the cut surface of the solder wire. There is a small hole in the center of the cut surface, indicating that it is rosin core solder wire. The one with the most is flux (rosin), and the one without small holes is solid solder wire. In the actual product welding, the solder wire can be selected according to the characteristics and process of its own product, whether it is solid core solder wire or rosin core solder wire, as long as it is suitable for its welding and can achieve the welding effect, it is an easy-to-use solder wire .
