What are the differences between rosin core solder wire and solid solder wire?

What are the differences between rosin core solder wire and solid solder wire? Generally, the two have different functions and should be relatively easy to distinguish. People with eyes can tell them apart. Solder wire is usually used for soldering electronic components. If the production process is different, it can be divided into these two products. Currently, in the market, most enterprises generally use rosin solder wire for processing, and this product is divided into many specifications and models. In this regard, JJYSolder paste manufacturerI can introduce it to everyone:

1.The effects are different.
During the entire soldering process, rosin is a flux. Its effect is to make the solder very easy to flow, touch firmly and have a bright surface. Rosin core solder wire is mostly useddiyAt work. Rosin can enhance the fluidity of liquid solder and also prevent the formation of an oxide film due to oxidation of the soldered metal materials. Overall, it is much easier to stick to than hollow ones.
2.The physical properties are different
In terms of form, previously, it was mostly solder rods, which were reduced to small pieces when used. Nowadays, with the integration of automatic soldering, it is mostly made into solder wires, including solid solder wires without flux and rosin solder wires with flux already encapsulated. When used, since the flux has already been added at the same time, electric soldering is more convenient.

The physical properties of the two types of solder wires are different
Solid core solder wire is made of pure tin without rosin and is similar to solder rods. Its physical properties are also the same as those of solder rods. When in use, the processing technology is probably used in conjunction with flux. However, rosin core solder wire introduces rosin into the inner part of the solder wire during production. When in use, since the flux has already been added, it is more convenient for soldering. Rosin core solder wire is divided into environmentally friendly solder wire and lead-containing solder wire. When choosing, it is necessary to communicate with the manufacturer to determine which type of solder wire is suitable with powerful functions (as mentioned earlier). However, it cannot have the same characteristics as solder rods. For example, when using a wave soldering machine, rosin type solder wire and solder rods cannot be used together in the soldering furnace or wave soldering furnace.

Shenzhen JJY has established mutually beneficial cooperation with electronic raw material producers and also provides services for other enterprisesSolder wireProduction of solder rods, solder pastes and flux pastes; With a rich variety of successful cases in the research and development of chemical raw materials, our overall strength has created a sales market that is of high quality and honest and trustworthy.
