provide the information which defines the board size, the height of key
components, as well as the location and dimensions of all connectors. Dimensions are shown in
British Imperial units (inches). Dimensions shown in [brackets] are in metric (millimeters).
Table 2
lists the part numbers of all connectors and their respective mating pair.

The six mounting holes have an inside diameter of 0.125 inches (3.175 mm) and are sized for a #4
screw. The pads have an outside diameter of 0.250 inches (6.35 mm). The minimum distance
between the center of the hole and the closest component or circuit trace is 0.140” (3.556 mm).
It is anticipated that the number of mounting holes, size of the holes and placement separations are
sufficient to satisfy most vibration requirements. Several customers have already satisfactorily tested
the vibration performance of the P440 in extremely challenging end applications.
The P440 board is built to IPC Class 2 standards. The tolerances associated with hole size and
centering are consistent with this standard.
