![]() ![]() ![]() The flux also reduces the surface tension between the two metals, allowing the solder to flow more evenly and strongly as it melts.Īdditionally, the flux helps to keep the heat of the soldering iron from being transferred to the adjacent materials, preventing damage that could be caused by excess heat. It works by creating a thin layer on the surface of the metals, which prevents oxidation and prevents the metals from forming any connection. It also helps to ensure a smoother and stronger connection between the two metals. Flux is a chemical that helps to clean and enhance the surface of the metals being soldered together. Incorrect flux can hinder the adherence of the solder even when other elements are properly accounted for. Lastly, the wrong type or quality of solder may be used, or if using lead-free solder, the wrong flux may be used. Improper temperature control may also be an issue, as too high of temperatures can cause oxidation on the component and board surfaces while too low of temperatures can prevent the solder from melting properly. This can also occur due to improper cleaning, resulting in insufficient heat transfer required to melt the solder. Another possible cause is poor surface contact between the component and board. If this is not done, oxidation can occur on the surfaces, preventing the solder from adhering properly. The most common cause is a lack of adequately cleaning the component and surface that are to be soldered together prior to the process. Solder not sticking to a surface or component can be caused by a variety of factors. Some popular fluxes for general use include rosin-based flux, alcohol-based flux, and synthetic flux. Therefore, when it comes to soldering, it is important to use an appropriate flux that is specifically designed for the type of surface you are working on. In addition, the residue that remains after a soldering job can potentially corrode the electronic components, especially if exposed to moisture. While Vaseline is a petroleum jelly product, it is not an effective flux because it will not remove oxides or other impurities from the surface. ![]() Flux is an substances that is used to clean and protect a surface, such as soldering and welding, by removing oxides, only allowing the desired melted metal to remain. Without flux, the metal and surfaces being soldered can be difficult to work with and the solder may not be able to bond correctly. Finally, flux helps to ensure that the metal and the surfaces being soldered are clean and free of any contaminants that can affect the end result of the soldering. Secondly, it helps reduce oxidation of the metals, meaning the risk of the metal corroding or tarnishing is minimized. ![]() The flux is an important component of solder and it serves multiple purposes.įirstly, it can help create a stronger bond between the metal surfaces. Solder is a combination of metals combined with flux that are melted with a soldering iron or other heat source in order to create a bond between two surfaces. But if the metal “hooks” are very close together, it can be difficult to get the piece of solder in the right place.įlux helps by creating a sort of bridge between the metal surfaces, which the molten solder can then flow across. If you picture the two metals you want to join as two pieces of Velcro, with the metal “hooks” interlocking, it’s easy to see how adding a piece of solder can help join them. The first is fairly self-explanatory – if there’s dirt, grease, or oxidation on the surfaces of the metals, it can prevent the solder from bonding properly. The heat source melts the solder, which then cools and bonds the metals together.įlux is generally used in two situations: to clean the surfaces of the metals before soldering, and to help the solder flow into and bond with the metals. Then, you apply a solder – which is a metal with a relatively low melting temperature – to the area. Simplified, the soldering process is as follows: you have a controlled heat source which you use to heat up both the metals you want to join and the area around it.
