<p>A cover assembly for an IC card includes top and bottom covers (52, 54) with overlapping side rails (70, 80). At each side of the card, a downwardly-extending top side rail (70) lies facewise adjacent to an upwardly extending bottom side rail (80), and a layer (90) of solder is sandwiched between the rails and is bonded to each of them. The solder layer extends along most of the height of each cover side, so the two rails and the solder layer between them serve as a single rigid beam. The cover assembly can be, instead, spot welded at a plurality of locations at each side of the card, to weld the two rails facewise together.</p> |
