Patent ID: 10541197

Abstract:
A press-fit pin increases contact area with the contact hole to provide appropriate contact pressure, reduce contact resistance, and increase heat transfer efficiency. The press-fit pin is of a semiconductor package including an end portion and a press unit extending from the end portion and is divided into a first press-fitting piece and a second press-fitting piece, the first press-fitting piece forming a convex portion in a first direction perpendicular to the direction of the press-fit pin and bending to a second direction perpendicular to the direction of the press-fit pin and forming 30-110 degrees with the first direction and the second press-fitting piece forming a convex portion in a third direction perpendicular to the direction of the press-fit pin and being 180 degrees with the first direction and bending to a fourth direction perpendicular to the direction of the press-fit pin and forming 250-330 degrees with the first direction.
