Latest Patents

Shigematsu's latest patent addresses the **Method of Connecting Circuit Boards**, which encompasses two key steps: an alkane application step and a heat-press-bonding step. In the alkane application step, an alkane group is applied to a printed circuit board. This preliminary action prepares the board for the subsequent heat-press-bonding step, where a flexible circuit board is bonded to the printed circuit board. The terminals of both boards are aligned to face each other during this process. The heat from the heat-press-bonding step causes the alkane group to boil, effectively cleaning the surface of the terminals by removing any oxide film and exposing the metallic portions. This method enhances firm bonding between the boards, ensuring both electrical and mechanical connections are achieved efficiently at a low cost and in a short time frame.
