It is fully compatible
with existing probe interface boards (PIBs) and probe cards, and is
well suited for high-speed multi-DUT applications where electrical
cross talk is of critical concern.
The PPR’s modular design groups the contacts into 8 removable
pin segments, each segment containing 128 high-speed 50-ohm contacts.
Each of these high-speed contacts has its own adjacent return contact
(common ground), which reduces simultaneous switching noise. Device
power supplies and other functions are routed through the utility
contacts. There are 102 of these utility contacts per segment, and
each contact can handle 3 amperes.

Fully populated, the PPR has 1,024 high-speed channel paths and 816 utility
contacts, but, if you prefer, you can configure it with only enough segments
to support your target tester configuration. Spring blocks are available
for any unused segment positions, to balance the forces on the probe card.
The 8.47”-diameter applications area on the probe/DUT card can accommodate
multi-DUT handler and probe patterns. A separate compression ring assembly
allows for program debug or hardware development free of the peripheral
(prober or handler). The compression ring works directly over the pin field
without infringing on the applications area. And you won’t need special
frame or mounting hardware for the probe/DUT cards.
