She has made significant contributions to the field of electronics, particularly in the development of wiring substrates and solder bump forming methods. With a total of 3 patents to her name, Oda continues to push the boundaries of innovation in her industry.

Latest Patents

Oda's latest patents include a wiring substrate and an electronic device. The wiring substrate features a first substrate that includes a wiring layer and a solder resist layer, which partially covers the wiring layer. This solder resist layer has a circular opening that partially exposes the wiring layer, along with a support that partially covers the wiring layer within the opening. The wiring layer contains a first connection pad that is exposed in the opening and formed by a portion of the wiring layer located at the outer side of the support. Additionally, the wiring substrate includes a cylindrical connection pin and a bonding member that bonds the first end surface of the connection pin to the first connection pad located in the opening.

Another notable patent is a solder bump forming method. This method involves carrying out a reflow treatment over a conductive ball mounted on multiple pads to form a solder bump. The process includes a metal film forming step, where a metal film capable of chemically reacting to a tackifying compound is formed on the pads. An organic sticking layer is then created by causing a solution containing the tackifying compound to chemically react with the metal film. Finally, a conductive ball is mounted on the pads that have the organic sticking layer formed on them.
