Solder flux chemical composition
WebJun 10, 2010 · Exposure to soldering fumes health effects mainly depends on the type of solder and the solder flux chemical composition. The most popular solders used contain lead, rosin, or are lead-free composed of tin, silver, and copper . Other specialized solders include alloys of beryllium, aluminum, gold, iron, and brass. WebFeb 28, 2024 · What soldering flux does. Understanding flux requires comprehension of what it does. As with most things related to soldering, that begins with wetting forces. Solder flow is called wetting. When solder flows over a surface like a component lead, it is said to “wet” the surface. Failure to flow is non-wetting.
