Designing and Probing with Target Connections
For All Agilent Logic Analyzers with 40-pin Pod Connectors
Figure 5.9. Pro Series soft touch footprint dimensions (see drawing notes).
Drawing notes:
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.
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.
Surface finishes on pads should be HASL
immersion silver, or gold over nickel.
This footprint is compatible with retention module
Agilent part number E5405-68702.
This through hole is not used with the Agilent
retention module.
Plated through hole should not be tied to ground
plane for thermal relief.
