Drawing notes:
1 Maintain a solder mask web
between pads when traces are
routed between the pads on the
same layer. The solder mask may
not encroach onto the pads within
the pad dimension shown.
2 VIAs 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.

Pad
3 Surface finishes on pads should be
HASL immersion silver, or gold over
nickel.
4 This footprint is compatible with
retention module Keysight part
number E5405-68702.
5 This through hole is not used with
the Keysight retention module.
6 Plated through hole should not be
tied to ground plane for thermal
relief.
