7.4 Mechanical Dimensions PROPOSED
The mechanical dimensions for the VRM 10.0 module and connector are shown in Figure 10.
7.4.1 Gold Finger Specification
The VRM board must contain gold lands (fingers) for interfacing with the VRM connector that
are 1.27 mm ±0.05 mm [0.050 inches ±0.002 inches] wide by 5.08 mm [0.200 inches] minimum
long and spaced 2.54 mm ±0.05 mm [0.100 inches ±0.002 inches] apart. Traces from the lands to
the power plane should be a minimum of 0.89 mm [0.035 inches] wide and of a minimal length.
