Organic solvents: ketones, alcohols, esters, a mixture of one or more flux component, commonly used are ethanol, propanol, butanol; acetone, toluene, methyl isobutyl ketone; ethyl acetate, butyl acetate and the like. As the liquid component, its main role is to dissolve the flux in the solid component, so as to form a homogeneous solution, to facilitate uniform coating of a suitable amount of a flux component to be welded elements, but it also can be cleaned of dirt, light oil and metal surfaces natural resins and derivatives or synthetic resin, the appearance of active agent: the appearance of active halogen-containing surfactant, high flux capability. Enhanced penetration of organic activator, also can play the role of organic blowing agent activator: from organic dicarboxylic acid or aromatic acid in one or more of the composition, such as succinic acid lead-free flux, E acid flux selection, itaconic acid, salicylic acid, sebacic acid, pimelic acid, malic acid, succinic acid. Its main function is to remove the oxide surface of oxides and molten lead solder feet, one of the key components of the anti-corrosive flux: reduced resin, solid content after activation agent pyrolysis residual material. Environmental flux, flux, flux provided by the Zhengzhou City, Henan Fujie Soldering Materials Co., Ltd. Zhengzhou City Fujie Soldering Materials Co., Ltd. (www.fujiehanxi.com) (www.fujiehanxi.com) strong, credible, in Zhengzhou, Henan electronics, electrical products processing industry has accumulated a large number of loyal customers.
