Latest Patents

Kashiwabara holds a patent for a soldering paste and flux. The objective of this invention is to provide a solder paste that enables the formation of a surface mounting structure for electronic components. This structure exhibits crack resistance in the solder joint section, even after enduring 100 heat-shock cycles at temperatures ranging from -40°C to 150°C. This capability is essential for applications near engines in vehicles. The solder paste is created by kneading a flux, which includes an amine halogen salt and a dicarboxylic acid, with a Sn–Ag–Bi–In alloy powder. The result is a solder paste that demonstrates long continuous printability, minimal occurrence of solder balls, and excellent joining ability without cracking under extreme temperature conditions.
