Success Story – RF Probe Station

March 05, 2020

Customer Requirements:

A customer wanted to automatically test individual filters used for 5G applications. The requirement was for a fully automatic RF probe station used in a high-volume wafer production environment that operated 24/7.  The RF devices were not in wafer form and could have variations in X,Y,Z and theta from device to device. The customer wanted to use a customized common carrier that would be used pre and post probe.

There was a family of devices to test at High Frequency (RF) so one of the manipulators was manual (3 axis) and the other was programmable (3 axis). This allowed one RF probe to remain fixed in contact while the other RF probe could be moved to contact various sized devices.
