Abstract
An IC card has a frame (14, FIG. 2) that protects the circuit board-and-connector assembly (12), wherein the frame is sturdy and of low cost and provides good EMI (electromagnetic interference) shielding. The frame includes lower and upper sheet metal shield halves (50, 52) each having large area sheets (60, 80) covering the bottom and top of the circuit board-and-connector assembly. The lower shield half has a pair of upstanding lower rails (70, 72) that extend along most of the length of each side, while the upper shield half has a pair of depending rails (86, 88) at its opposite sides that lie facewise against the outer surfaces of the lower rails. The lower ends (100, FIG. 4) of the upper rails are bent 90.degree. to lie under the lower sheet, and the upper ends (112) of the lower rails abut the upper sheet. The circuit board and connector assembly is placed in the lower shield half, and the upper shield half is positioned with its rear end aligned with the front end of the lower shield half, with the upper shield half then being slid rearwardly to its final position.
