63-37 Tin Lead Solder Wire 0.3mm for Electrical Soldering Tin 63% Lead 37% Sn63 Pb37 HX-100 Electrical Solder Wire 55g

Used in some paper PCB boards that cannot be resistant to high temperature, fine spacing and high-precision components avoid the phenomenon of displacement of the stele. It has good continuous printing performance and is suitable for welding of general fine spacing and precision components. The upper tin is full and bright, with less white transparent and no strong corrosive substances such as fluorine. Insulation resistance, cold collapse and dry strong, suitable for ICT performance testing.
