The laboratory is a state-of-the-art facility for characterizing and analysis of power modules, discrete transistors and similar power electronics components. The lab is used in post-production quality control for power electronics packaging activities at AAU. It furthermore facilitates the creation of static and dynamic models of power semiconductors.
In reliability studies, pre- and post-stress analysis of power semiconductors can quantify the impact of stressor on the performance of the device under test. Non-destructive analysis methods can be used to monitor the wear-out of the DUT during the lifetime tests.
KSI v8 scanning acoustic microscope
Uses ultrasound waves for non-destructive analysis of semiconductor assemblies. Can detect voids, cracks, and delaminations inside a sealed package. 20MHz and 50MHz transducers are available with resolution down to 20µm
Keysight B1506A power device analyser
A fully automated power semiconductor analyser capable of automatically producing full device datasheet. Static characteristics up to 3 kV and 1500 A. Features measurement of transistor input, output and reverse transfer capacitances (Ciss, Coss, Crss) as well as gate charge (QG) and resistance (RG).
Fast −50°C to +250°C temperature control system. Can be remotely controlled by the Keysight B1506A power device analyser. Can be programmed to cycle the temperature for reliability studies.
Keysight E4990 impedance analyzer
A 20 Hz to 120 MHz impedance analyzer for characterization of passive components (transformers, inductors, capacitors and DC-link capacitor banks), semiconductor devices, magnetic materials and dielectric materials.
