Abstract
Abstract A semiconductor device card includes a frame on which a semiconductor module may be mounted and a protection panel adhered to the frame. The frame includes pairs of offset grooves along each of two opposed sides and the protection panel includes pairs of offset flanges along each of two opposed edges of the panel. The protection panel flanges are inserted into the grooves in the frame and adhered to the frame in the grooves. Thus, a large attached area for ensuring good adhesive strength between the frame and the protection panel is achieved.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
A semiconductor device card comprising: a four sided frame defining an area and in which a semiconductor module board may be mounted, the frame including first and second opposed sides and third and fourth opposed sided, the first and second sides each including a first groove and a second groove offset from the first groove; and a metal protection panel fixedly adhered to the frame, said metal protection panel having opposed first and second longitudinal edges, each edge including a first and second flange, the first and second flanges being offset from each other, wherein the first and second flanges at the first longitudinal edge of the metal protection panel are respectively inserted into the first and second grooves in the first side of the frame and the first and second flanges at the second longitudinal edge of the metal protection panel are respectively inserted into the first and second grooves in the second side of the frame and the flanges are adhered to the frame in the grooves with the protection panel covering the area.
Claim 2
Dependent Claim
