Latest Patents

Yamaguchi's latest patents include a fixture, a circuit board with a fixture, and an electronic-component mounted body along with a method of manufacturing the same. The fixture he developed features movable pawls and positioning walls that facilitate the insertion of electronic components from the upper side. The design allows the movable pawls to move outward, enabling the electronic component to fit securely between the positioning walls. Once fitted, the movable pawls hold the component in place, ensuring that the bumps on the electrode pads connect effectively to the circuit board's electrodes. This design allows for the use of the flip chip technique, which enhances the mounting process. Additionally, the electronic component can be easily removed by manipulating the movable pawls, even after it has been mounted.

Another notable patent involves a multilayer wiring board embedded with a transmission line conductor. This innovative structure consists of a pair of signal conductors embedded within a dielectric layer. The design ensures that the coupling impedance between adjacent signal conductors is lower than that between a signal conductor and another conductor in a different wiring region. This advancement results in a multilayer wiring board that boasts high wiring density and excellent transmission characteristics.
