Latest Patents

Among Takashi Ishii's latest patents are two groundbreaking innovations aimed at improving solder preform production. The first patent, titled "Solder preform and a process for its manufacture," introduces a method involving a mixed mother alloy prepared from solder mixtures that includes pyrolyzable flux and high melting point metal particles. This method leads to the production of a billet that can be extruded, rolled, and punched into various forms, including pellets and washers.

The second patent, "Process for producing a solder preform having high-melting metal particles dispersed therein," addresses challenges faced during the traditional solder preform manufacturing process. Traditionally, the dispersal of high-melting metal particles into molten solder was time-consuming and resulted in a reduction of particle size due to dissolution. Ishii's innovative approach involves creating a premixed master alloy with a higher proportion of metal particles, enabling a uniform and rapid dispersal in solder. This advancement maintains ideal clearance between soldered components, ultimately enhancing bonding strength and application efficiency.
