juotossuojan
Juotossuoja, often translated as a soldering flux or paste, is a substance used in electronics soldering to facilitate the formation of a strong and reliable electrical connection. Its primary function is to remove existing oxidation from the metal surfaces to be joined, such as copper pads on a printed circuit board and the leads of electronic components. Oxidation is a natural process that forms a layer of metal oxide on the surface, which acts as an electrical insulator and hinders solder flow.
Juotossuoja typically consists of a fluxing agent, a solvent, and sometimes metallic particles or activators. The
Different types of juotossuoja exist, varying in their chemical composition and intended applications. Some are designed
