Latest Patents

One of Tsuchita's latest patents involves a revolutionary soldering method and soldering apparatus. This invention discloses methods and apparatuses that allow soldering to take place while the chip is held by a head under melted solder conditions. Specifically, solder bumps are formed on the chip and positioned opposite terminals on a mounting board. A heating block is strategically located at the back of the chip, raising the temperature of the solder bumps to their melting point through conduction. Additionally, another heating block at the back of the mounting board facilitates the soldering process by enabling the solder bumps to make contact with the terminals while molten.

Another notable patent by Tsuchita is for a manufacturing process for organic chip carriers. This innovation allows for the formation of a substantially bowl-shaped via hole in the substrate of the chip carrier. This unique design simplifies the deposition of a conductive layer with a uniform thickness along the sidewall of the via hole. By using photosensitive resin, Tsuchita’s method involves creating cavities in a predetermined pattern, heat-curing the resin, and removing layers to achieve the bowl shape necessary for effective manufacturing.
