Title: Kei Anai: Innovator in Bonding Compositions
Introduction
Kei Anai is a prominent inventor based in Ageo, Japan. He has made significant contributions to the field of bonding compositions, holding a total of 13 patents. His innovative methods and compositions have advanced the technology used in various applications.
Latest Patents
One of Kei Anai's latest patents is a method for producing a bonding composition that contains copper particles and a second liquid medium. This method involves producing copper particles in a first liquid medium using a wet reduction method, resulting in a dispersion of the copper particles. The first liquid medium is then replaced with the second liquid medium while maintaining the dispersion in a wet state. The process is optimized to occur at temperatures lower than 100° C, and the second liquid medium can include water, alcohol, ketone, ester, ether, or hydrocarbon.
Another notable patent is for a composition for pressure bonding, which contains a metal powder and a solid reducing agent. This composition has a compressibility ranging from 10% to 90%. The compressibility is defined by a specific relationship formula involving the thickness of a dried coating film and the thickness of a sintered body formed under specific conditions. The solid reducing agent used may be BIS-TRIS, and the invention also includes a bonded structure of conductors treated under pressure with the bonding composition.
