The new Agilent E5400-pro series soft touch probes are
ultra- low-load connector- less probes that work with the
Agilent logic analysis modules. The probes attach to the PC
board using a retention module which ensures pin- to- pad
alignment and holds the probe in place.
•The E5402A- pro series probe is a low- profile right- angle
34- channel single- ended connectorless soft touch probe
(for analyzers with 90- pin cable connectors).
•The E5404A- pro series probe is a 34-channel single- ended
connectorless soft touch probe (for analyzers with 40- pin
cable connectors).
•The E5405A- pro series probe is a 17-channel differential
connectorless soft touch probe (for analyzers with 90- pin
cable connectors).
•The E5406A- pro series probe is a 34- channel
single-ended connectorless soft touch probe (for analyzers
with 90- pin cable connectors).
Use the following information to design your target system
board for use with the Agilent soft touch probes.

Installation Instructions
1Use the information provided in Chapter 2 to design pads
on your board and holes for mounting the retention
module.
The soft touch probes are attached to the PC board using
a retention module which ensures pin-to- pad alignment
and holds the probe in place.
2Use flux as necessary to clean the board and pins before
soldering the retention module to the board.
3If your board has Organic Solder Preservative (OSP)
finish, apply solder paste to the footprint pads prior to
reflow or hand soldering.
Typically, dipped and coated finishes do not require extra
solder paste.
4Attach the retention module to the board from either the
top or bottom of the board:
Top- side attach
Can be used with most board thicknesses.
aInsert the retention module into the board noting the
keying pin.
bSolder alignment pins from the top ensuring that solder
is added until a fillet is visible on the pin.
