RFIM MEASURING CELL

The fully automated measuring cell can be controlled via a measuring computer provided by the customer with defined commands and parameters. This allows the customer to design the measuring process flexibly. The robot can be loaded with up to 20 RFIM components in a magazine. A handling system (4-axis robot) removes the RFIMs from the magazine using a pneumatic gripper and places them in the test nest. There, the RFIMs are centered and contacted from below with RF connectors. At the same time, the cooling water supply is docked onto the RFIM. Another 4-axis robot approaches the contacts to be measured with signal frequencies in the gigahertz range on the top of the RFIM. Numerous actuators and sensors control and monitor the measuring process, the handling systems and the cooling water flow.

A PLC controls all processes and communicates with the customer's measuring computer. After characterization, the RFIM is returned to the magazine and the next component is inserted into the test nest. The RF measurement technology is very sensitive and must be positioned with high precision. The handling system uses various tools to automatically calibrate the entire measurement setup before the actual characterization of the RFIMs begins. The various calibration tools are mounted on the handling system using a pneumatic tool changing system.
