Latest Patents
Yokokoji's latest patents include an electromagnetic wave absorbing element and a process for manufacturing a printed circuit board. The electromagnetic wave absorbing element consists of an elongated rectangular body made of dielectric material. This body has a bottom portion that can be attached to the inner wall of an electromagnetically dark room. The design allows for a set of absorbing elements to be arranged in rows and columns on the wall. An electroconductive ink film is formed on the peripheral faces of the body, featuring a surface resistivity that decreases exponentially toward the bottom portion. This innovative design effectively absorbs incident electromagnetic waves.
The second patent, a process for manufacturing a printed circuit board, involves transferring flux from a supporting film to the surface of the board. After the supporting film is removed, electronic parts are soldered onto the board. The method includes coating the supporting film with flux and applying heat and pressure to transfer it to the printed circuit board. This approach ensures a uniform flux coat and addresses various drawbacks found in conventional methods.
