Must maintain a solder mask web between pads when traces are
routed between the pads on the same layer. Soldermask may not
encroach onto the pads within the pad dimension shown.

Via in pad not allowed on these pads. Via edges may be tangent
to pad edges as long as a solder mask web between vias and pads
is maintained.

Permissible surface finishes on pads are HASL, immersion silver,
or gold over nickel.

Footprint is compatible with retention module,
Agilent part # E5387-68702.

Retention module dimensions are 34.04 mm x 7.01 mm x 4.98 mm
tall relative to the top surface of the PDB. Retention pins extend
4.32 mm beyond the bottom surface of the RM through the PCB.

Assume normal artwork tolerances for pad size dimensions.
