Introduction

Kenji Matsui is a notable inventor based in Kitamoto, Japan. He has made significant contributions to the field of liquid flux technology, particularly through his innovative patent that enhances soldering processes.

Latest Patents

Matsui holds a patent for a flux composition that incorporates a polyamide resin. This resin is compatible with rosin-based resins and serves as a key component in liquid flux and solder paste flux. The invention is designed to be resistant to temperature variations and provides a damp proofing effect. Specifically, the polyamide resin is obtained through a polycondensation reaction of a dicarboxylic acid with 2 to 21 carbon atoms and a diamine, or from a dimer acid and a diamine. The resulting fluxes are low-viscosity and maintain solderability, ensuring that flux residues on printed circuit boards do not crack or deteriorate under temperature changes. This innovation also prevents poor insulation and migration in high humidity environments.
