Quality verification for ICR Near-field microprobes
After the production each ICR-Microprobe has to be calibrated. Therefor the frequency response is measured above a defined stripeline and calibration data are created.
Measurement setup
Technical parameters:
Stripline | Width: | 25 µm | | Spectrum analyzer | TG-Level: | 100 dBµV |
Length: | 2 cm | Ref.-Level: | 100 dBµV | |||
50 Ohm | RBW: | 1 MHz | ||||
Measure distance to probe: | 20 µm | VBW: | 100 KHz | |||
Result:
For each delivered micro probe achieve our customers a certificate with the measured characteristic curves for the respective maximum and minimum. [Probe types] Both curves describes the quality of a micro probe. Furthermore a correction file is created. With this file it is possible to measure with each delivered micro probe applying to a reference level the same. The required calculation could be done in ChipScan or Excel.
- Probe characteristic (frequency response of the ICR-Near-field Microprobe)
- Measuring result of the maximum above the same stripeline with the calibration data
