PEGASUS PROBE - DESCRIPTION
The Pegasus Probe was designed for use as a single probe with integrated edge sensor.
There are eight mounting positions that can be used for a combination of Pegasus Probes
and Inkers.
The first Pegasus Probe of any combination is the fixed probe. The position of this probe
will be set prior to shipment, such that the nominal position of the needle will be coincident
with the chuck centre when the prober is first initialised. Whilst it is possible to adjust the
position of this probe, it should not be necessary. Where a device has more than one pad, or
if multi-die probing, subsequent Pegasus Probes should be of the adjustable type. (See
photo below).
