InfinityQuad

A configurable fine-pitch multi-contact RF/mmW probe for mixed-signal probing up to 110 GHz

InfinityQuad Overview

For repeatable and precise engineering tests of DC, logic, RF and mmWave RFIC devices, the InfinityQuad™ probe ensures reliable measurement results up to 110 GHz over a wide temperature range (-40 °C to 125 °C). The durable photo-lithographically defined fine-pitch tip structure enables probing of small pads down to 30 x 50 μm with minimum pad damage and consistent low contact resistance. The durable probe tips with small contact area of ~10 μm diameter ensure more than 250,000 touchdowns on Al pads, and provide accurate X, Y and Z alignment.

Pads as small as 30 μm x 50 μm become a reality in automated over-temperature probing applications. This allows the user to reduce pad sizes, saves device real estate space and lowers pad parasitics – both saving money and improving measurement accuracy.

InfinityQuad technology reduces the minimum size of the pad that can be used with a multi-contact, mixed-signal probe. And for customers already using small pads, you can repeatedly make contact with the pad – reducing the amount of time needed to manually test or eliminating the need to repeat automatic tests due to probes skating off the pads.
