Figure 2: COMe-cXLi2 COM Mechanical Drawing
All dimensions are shown in millimeters. The COM Express® specification says
that these holes should be ± 0.25mm [±0.010"], unless otherwise noted. The
tolerances for placement of the COM Express connector with respect to the peg
holes (dimensions [16.50, 6.00]) should be ± 0.10mm [±0.004"]. The 220-pin
connector is mounted on the back of the PCB and is seen “through” the board
in this view. The 4 mounting holes shown in the drawing use 6mm diameter pads
and 2.7mm plated holes for use with 2.5mm hardware. The pads are tied to the
PCB ground plane. Gray circles represent the mechanical mounting holes.
Black circles represent the mounting holes required by the PICMG COM Express®
standard.
