7.4 Mechanical Dimensions - PROPOSED
The mechanical dimensions for the VRM 10.1 module and connector are shown in Figure 7-1.
7.4.1 Gold Finger Specification
The VRM board must contain gold lands (fingers) for interfacing with the VRM connector that is
1.27 mm ±0.05 mm [0.050” ±0.002”] wide by 5.08 mm [0.200”] minimum long and spaced
2.54 mm ±0.05 mm [0.100” ±0.002”] apart. Traces from the lands to the power plane should be a
minimum of 0.89 mm [0.035”] wide and of a minimal length.
