4、uration (see table II) Example: AA59590/14CT38E is the PIN for a chemical film finished, 3.8 inch (96.5 mm) long visual lock indicating card holder. The card holder also features two tapped mounting holes for use with 080 UNF fasteners and a self-locking element on the end of the actuating screw for
5、 added resistance to loosening. SALIENT CHARACTERISTICS. 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
6、 C/W/inch thermal resistance transfer between the circuit 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 sh
7、all be as specified on figures 1, 2, 3, and 4, in table I, and AA59590. Visual lock indicator (see figure 2). Card holders shall have a visual indicator to show when the card holder is in its relaxed (unlocked) state. When the card holder is in the unlocked (relaxed) state, the actuating end of the
8、screw shall display a red band on the side of the screw. When the actuating screw on the card holder has been tightened (assembly expanded) so that the assembly is in the locked position, this red band shall be concealed. Actuating screw hex drive socket. The across flats dimension for the hex drive
9、 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 holders are used in cold plate applications, the nominal installation torque of each card holder sha
10、ll 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“.

14、t 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). Finish. The finish designator shall be as specified in AA59590. The finishes available for this CID specification she
15、et are as follows: “B“ (black anodize), “C“ (gold chemical film), “H“ (hard black anodize), or “R“ (clear chemical film). Mounting. The mounting designators shall be as specified in AA59590. The mounting options available for this CID specification sheet are as follows: “J“ (rivet mounting holes), “
16、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. Mounting hole locations (when req
17、uired). 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 may be present on card holders greater than 5.30 inches (134.6 mm) in length. The third mounting hole, when present, shall be centere
18、d on the mounting body. See figure 1 and table I and 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 5.08 mm) diameter with an acce
