4、e II) Example: AA59590/12CT48 is the PIN for a chemical film finished, 4.8 inch long card holder with a lock nut on the screw for captivation. The card holder also features two tapped mounting holes for use with 080 UNF fasteners. SALIENT CHARACTERISTICS. Performance. Card holders shall hold the cir
5、cuit card assembly firmly in its installed position. When the card holder is installed properly, it is capable of withstanding 60g/6ms of shock, 25 G-rms of vibration, and provides from 2 to 4 degrees C/W/inch thermal resistance transfer between the circuit card assembly and the heat sink surfaces.
6、Material. Unless otherwise specified herein, the card holder materials shall be as specified in AA59590. Interface and physical dimensions. The card holders supplied to this CID specification sheet shall be as specified on figures 1, 2, 3, 4, in table I, and AA59590. Actuating screw hex drive socket

The across flats dimension for the hex drive socket shall be as follows: .094 inch (2.38 mm) for mounting options “J“, “N“, “T“, “R“, “V“, and “S“ and 2.5 mm (.098 inch) for mounting options “G“ and “M“. Screw retention (locknut). The screw retention feature intended to prevent unintentional disas
8、sembly of the card holder shall be as specified in figure 2. The locknut shall be fabricated of a corrosion resistant material. Nominal installation torque. When card holders are used in cold plate applications, the nominal installation torque of each card holder shall be 4 to 6 inch-pounds (0.45 to
9、 0.68 N-m). Cold plate slot width dimensions (when applicable). The recommended cold plate slot width to accommodate the circuit card assembly with attached card holder is .210 inch (5.33 mm) plus the thickness of the printed board of the circuit card assembly (see AA59590).
