VXI Bus Mechanical Board Dimensions Drawing

This is a diagram of a VXI bus 'D' size card. The maximum size of the D board is below. The connector locations and component keep-out areas are indicated, face-plate screw locations are also indicated. The normal width for a VME [or VXI board] is 90 mil, if the card is thicker because of an increase number of layers then the card edges may be milled top and bottom so that it would slide into a normal card guide. Additional data is provided after the graphic, Component height and other detailed data on the VME bus may be found on the VMEbus page, or VXI bus page.

IEEE 1101.1 Base Document for Mechanics ~ Defines 3U/6U/9U (high) x 100/160/220/280/340/400mm (Long) cards
IEEE 1101.10 Mechanics for VME Boards and Subracks
IEEE 1101.11 Mechanics for Rear Transition Modules

Three card heights are allowed with VME; 3U, 6U, or 9U; a single slot card is 6T wide. Length is either 160mm or 340mm (Norm)
Height is given in 'U' [1U = 43.60mm], Length is given in 'mm', Width is given in 'T' or HP [1HP = 5.08mm [HP: Horizontal Pitch];
Card sizes listed below are one slot or 6T wide
A size PWB Dimensions = 3U x 160mm,
B size PWB Dimensions = 6U x 160mm,
C size PWB Dimensions = 6U x 340mm,
D size PWB Dimensions = 9U x 340mm ... H x L x W {@ width=6T}
A, B, C, and D are VXI terms. VME normally only references 3U or 6U by a length
