4、e: AA59590/13HV28W is the PIN for a hard black anodize finished, 2.8 inch (71.1 mm) long card holder. The card holder also features two tapped mounting holes for use with 256 UNC 2B fasteners and a lockwasher and flat washer under the screw head for added resistance to loosening. SALIENT CHARACTERIS
5、TICS. Performance. Card holders shall hold the circuit card assembly firmly in its installed position. When the card holder is installed properly, it is capable of withstanding 60g/6ms of shock, 25 Grms of vibration, and provides from 2 to 4 degrees C/W/inch thermal resistance transfer between the c
6、ircuit card assembly and the heat sink surfaces. 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, and 3, in tabl
7、e I, and AA59590. Actuating screw hex drive socket. The across flats dimension for the hex drive socket shall be as follows: .140 inch (3.56 mm) for mounting options “J“, “N“, “T“, “R“, “V“, and “S“ and 3.0 mm (0.118 inch) for mounting options “G“ and “M“. Nominal installation torque. When card hold
8、ers are used in cold plate applications, the nominal installation torque of each card holder shall be as follows: 16 to 20 inch-pounds (1.8 to 2.3 N-m) for assemblies using no options or option “W“ and 17 to 21 inch-pounds (1.9 to 2.5 N-m) for assemblies using options “E“ or “D“. Cold plate slot wid
9、th dimensions (when applicable). The recommended cold plate slot width to accommodate the circuit card assembly with attached card holder is .425 inch (10.80 mm) plus the thickness of the printed board of the circuit card assembly (see AA59590).

14、lows: “J“ (rivet mounting holes), “N“ (no mounting holes), “T“ or “R“ (tapped 080 UNF 2B holes), “V“ or “S“ (tapped 256 UNC 2B holes), or “G“ or “M“ (tapped M2.5 x.45 metric holes). Card holders using mounting option “J“ may be shipped unassembled. See figure 1 for mounting hole spacing requirements
15、. Mounting hole locations (when required). When mounting holes are specified in the PIN, two mounting holes are required on card holders less than 5.30 inches (134.6 mm) in length. Three mounting holes are required on card holders 5.30 inches (134.6 mm) or greater in length. The third mounting hole,
16、 when present, shall be centered on the mounting body. See figure 1 and table I for mounting hole locations and spacing requirements. Rivet mounting holes. The holes used for rivet mounting shall be .136 inch (3.45 mm) diameter through holes, countersunk 100 degrees by .190 to .200 inch (4.83 to 5.0
