Latest Patents
One of Kanno's latest patents involves the development of circuit boards using heat-resistant resin for adhesive layers. This adhesive composition includes a polyamide-imide resin with a molecular weight of 80,000 or more, combined with a thermosetting component that includes an epoxy resin and a curing agent. This innovation provides an insulating adhesive layer with a storage elastic modulus at 300°C of 30 MPa or more and a glass transition temperature of 180°C or higher. The insulating adhesive is particularly suitable for wire scribed circuit boards, multilayer printed circuit boards, and circuit boards for chip carriers.
Another significant patent by Kanno details a process for producing printed wiring boards. This process is characterized by forming a nickel layer through electroless plating, followed by a copper layer also formed by electroless plating. Alternatively, a copper undercoating layer can be formed before the nickel layer. This method results in printed circuit boards that exhibit excellent resistance to electrolytic corrosion and are suitable for high-density component mounting.
