Automation of the test procedure for accelerated aging of implant packages

An automated accelerated aging test procedure is presented to estimate the lifetime of implant packages regarding hermeticity. Intruding humidity is captured automatically in packages at two elevated temperatures using a resonant circuit comprised of capacitive humidity sensor and coil in coupling with an external coil. Described are the test stand setup including sensor calibration and evaluation, data acquisition and processing. In a first application the safe and reliable operation of the setup is demonstrated.
