Title: Innovator Spotlight: Takahiro Hattori
Introduction
Takahiro Hattori is an accomplished inventor based in Tochigi, Japan, with a remarkable portfolio of 13 patents. His work primarily focuses on advancements in solder materials and techniques, contributing significantly to the field of electronics.
Latest Patents
Among Hattori's latest innovations is the "Method for forming bump electrode substrate." This method involves applying a first flux on an electrode located on a substrate, followed by placing a solder material on the electrode and heating it to form a solder bump. The process includes deforming the solder bump to create a flat surface or a depression, applying a second flux, and attaching a core material through a solder layer. This innovative approach enhances the reliability and performance of electronic components.
Another noteworthy patent is focused on a specific solder alloy, which comprises 0.005 mass % to 0.1 mass % of manganese (Mn), 0.001 mass % to 0.1 mass % of germanium (Ge), with tin (Sn) making up the balance. This composition ensures that a plurality of Ge oxides is distributed on the outer surface of an oxide film, improving resistance to discoloration, especially under high-temperature and high-humidity conditions.
