IV and CV measurements in the Liverpool clean room.

Cold IV:

Setup to measure IV PCB's at temperatures below 0°C. This is done by placing the PCB on a holder with a fan in a commercial freezer. The issue with this system is that the freezer has a cooling cycle and the temperature varies a few degrees when not constantly running. The lowest possible temperature is approximately -23°C. To get to lower temperatures and also have a more stable temperature of the device, a new cold IV setup was designed which will be placed in the freezer. The PCB is cooled with a Peltier element. The hot side is connected with a chuck which allows cooling with a liquid (or gas). The PCB is covered with a Perspex box which will be flushed with Nitrogen to prevent condensation.

TCT PID controller: more information about the PID controller

For IV study: glued sensor on PCB, PT1000 glued on sensor, soldered to PCB
