Abstract
A frameless IC card is provided, with a rear board support (26) to hold the rear of a circuit board, wherein a single design of rear board support can hold circuit board rear ends (24A, 24B, 24C) at a selected one of a plurality of different heights. The rear board support has top and bottom horizontal flanges (52, 54) and a plurality of vertical ribs (61-66) merging with the flanges, with the ribs being laterally spaced apart. A first set of vertical ribs (61, 62) has horizontal grooves (71, 72) of a first height extending into its front edge, with the grooves being about as thick as the circuit board, to closely receive the rear (24A) of a circuit board and thereby vertically position it. The rear board support includes a second set of ribs (63, 64) with horizontal grooves (73, 74) lying at a different height, to thereby hold a circuit board rear end (24B) at a different height, thereby enabling the same rear board support to hold circuit boards at selected heights. The rear of the circuit board has slots (83-86, 112-113, 115-116, 121-124) that receive ribs that do not closely position the height of the circuit board. The rear board support has forwardly-projecting latch legs (13…
