环保助焊剂通常是以松香为主要成分的混合物，是保证焊接过程顺利进行的辅助材料。焊接是电子装配中的主要工艺过程，助焊剂是焊接时使用的辅料，助焊剂的主要作用是清除焊料和被焊母材表面的氧化物，使金属表面达到必要的清洁度。
它防止焊接时表面的再次氧化，降低焊料表面张力，提高焊接性能。助焊剂性能的优劣，直接影响到电子产品的质量。
Environmental flux is usually to rosin as the main component of the mixture, is to ensure the smoothness of the welding process of the supporting material. Welding is the electronic assembly in the main process, flux is used for the welding materials, the main function is to remove solder flux and the welding surface of base metal oxide, metal surface so that achieve the necessary cleaning degree.
It prevents the welding surface is oxidized again, reduce the surface tension of solder, improve welding performance. Flux performance, directly affect the quality of electronic products
