Title: Mamoru Kakuishi: Innovator in Soldering Technology
Introduction
Mamoru Kakuishi is a notable inventor based in Tochigi, Japan. He has made significant contributions to the field of soldering technology, particularly with his innovative methods that enhance the efficiency and effectiveness of soldering processes.
Latest Patents
Kakuishi holds a patent for a unique soldering method that prevents solder scattering during reflow. This method thoroughly removes oxide films formed on the surfaces of solder or electrodes. The patented process involves several key steps: applying solder paste to the electrode on a printed circuit board, mounting an electronic part on the solder paste, and then heating the printed circuit board in a vacuum chamber at approximately 180 degrees Celsius to volatilize the residue-free flux. Following this, the oxide films are removed by heating the board in a formic acid atmospheric state at around 200 degrees Celsius. Finally, the solder powder is melted by heating the board in a vacuum chamber at 250 degrees Celsius.
