Flexible Tips for Flexible Probing

Each Model 50A has patented, independently spring loaded tips. Because the tips are flexible they minimize circuit damage, increase probe life, ａnd most importantly, provide a reliable individually spring loaded contact for each point. With a small amount of overdrive, the point scrubs the surface to make a reliable contact free of dust, dirt, ａnd oxide contamination. The ability to view the exact contact area eases probe positioning ａnd allows for the precise positioning necessary for good LRM calibrations. The flexible tips even allow probing of non-planar surfaces such as ceramic substrates ａnd laser diode structures.

Coaxial Transmission Improves Performance

The Model 50A uses a precision miniature 50 ohm coaxial cable from the probe tips to the connector interface. The coaxial design provides lower loss ａnd less radiation than coplanar designs. The miniature coaxial cable is fabricated from flexible Beryllium-Copper which greatly improves the probe’s durability.

Probe Cards

The Model 50A as well as all of our RF probes can be mounted on standard 4.5 inch probe cards and/or custom-sized cards to provide a convenient method for testing wafers at high frequencies using standard automatic or manual probe stations. Picoprobe Probe Cards can incorporate our Model 50A probes for RF connections with DC needles for power ａnd low frequency signals.

Multi-Contact Wedges

Our unique Multi-Contact Wedge designs accommodate multiple RF ａnd DC contacts on a single, compact adapter. This compact design provides the user with a convenient method for testing wafers at high frequencies using standard automatic or manual probe stations. The user can choose from a variety of wiring options for the DC or power needles ａnd ｓelect any combination of 40, 50, 67, and/or 110 GHz RF probes.
