Description:


Pb90Sn10 is a tin-lead solder with a high lead content, with a melting point of 275/302°C. As a traditional brazing material, Pb90Sn10 has been widely used in the high temperature field of microelectronic packaging. Tin-lead solder is a soft soldering material with good flow and corrosion resistance, small thermal resistance and good electrical conductivity.


Tin-lead solder has good corrosion resistance and good wettability to copper and copper alloys. It is widely used in electrical parts, components and lead connections, as well as common terminals and printed circuit boards.
