Tin wire wholesale has strong solderability, strong temperature resistance, high high temperature strength and good temperature and corrosion resistance, especially suitable for high temperature devices and high temperature working environment welding. After soldering, the components and components on the PCB board can pass the high temperature requirements of the tin furnace steadily, the solder joints are firm, and the fluidity is strong. It is suitable for welding high temperature double-sided PCB boards and secondary reflow soldering and long-term high temperature environment. Welding of working devices (such as lamp holders, motors, lighting industries, etc.) and electronic devices under higher humidity conditions.
