Latest Patents

Inatsugu's latest patents include a lead frame and semiconductor device. This lead frame features a dam bar and leads connected by the dam bar. Each lead consists of an inner lead located on one side of the dam bar and an outer lead on the opposite side, formed integrally with the inner lead. The inner lead includes a basal portion closer to the dam bar, a distal portion on the opposite side, and an intermediate portion connecting the two, with a varying width. A plating layer covers the upper surface and side surface of the distal portion, as well as part of the intermediate portion's side surface. Notably, the side surfaces of the basal portion and the dam bar are entirely outside the plating layer.

Another patent involves a lead frame manufacturing method. This method includes steps such as forming multiple opening portions by punching predetermined areas of a metal plate and creating crushed portions by reducing thickness at the margins near the opening portions. The process defines a width between side surface portions and center portions to ensure proper intervals between lead portions. Additionally, it specifies the widths of the top end and base portions through further punching of the metal plate.
