Probing Solutions for 90-pin Logic Analyzers
Soft Touch Connectorless Probing
Several options are available for connecting Keysight logic analyzers with 90-pin pod
connectors to a target system using mass connections.
Keysight Pro Series soft touch connectorless logic analyzer probes
Keysight has developed connectorless logic analyzer probes based on soft touch
probing technology. Connectorless logic analyzer probing removes the connector that
is traditionally attached to the target board and replaces it with an array of probe pads.
This reduces the probe load on the target by eliminating the loading associated with
the physical body of the connector. Additionally, this streamlines the design flow by
eliminating the need to assign a logic analyzer connector to the bill of material of your
board, procuring those connectors and then having them loaded onto your board.
Keysight’s soft touch connectorless probes use micro spring-pin technology to provide
reliable contact which is not dependent on the planarity of the PC board or the plating
processes used to fabricate the board. No special cleaning processes are required when
using Keysight’s soft touch probes.
The new Keysight Pro Series soft touch connectorless probes offer a 30% smaller
footprint than the original soft touch probes and are the basis for the industry standard
connectorless probing footprint.
The probes use a retention module that ensures soft touch pin-to-PC board pad
alignment and holds the probe in place while in use. The Pro Series soft touch uses a
“top-side” mountable retention module. The retention module is mounted on the same
side of the board as the probing footprint so there is no need to access the back-side
of the board. Because there is no requirement for the retention module pins to extend
beyond the back-side of the board, the retention module is compatible with virtually any
board thickness.
