Often rosin. Before starting welding electric soldering iron tip at blanched rosin, on the one hand iron temperature slightly lower, on the other hand is to oxidation, solder material, clean the tip and on the use of rosin solder heat volatilization occurred . Tip with rosin to the pads on the printed circuit board or the component leads, but also the use of rosin to oxidation volatilization, solder wire quotes, remove the pads or component leads oxide layer and simultaneously welding or to tin element. Peeling machine can be used prior to extrusion, extrusion tin round before casting surface disposal. Before being placed in an extruder, a good cast tin cylinder surface will be peeling treatment, Zhengzhou wire, thus treated tin tin cylinder cylinder can effectively remove surface oxides and debris, more likely to ensure the reliability of solder quality . Whether or not before stripping process, into an extruder, solder wire agency, should be rubbed on the surface layer of tin cylinder lubricating oil, ensure extruded molding can be passed, and the reduction of friction tin solder between the die orifice force, both to ensure uniformity of extruded wire speed, but can also help extend the life of the mold used. Solder wire agency, Zhengzhou solder wire, solder FUJIE provided by Zhengzhou City Fujie Soldering Materials Co., Ltd. Zhengzhou City Fujie Soldering Materials Co., Ltd.
