Reliability and Life-time Sensor Testing
Single Axis Force Shakers with Temperature Chamber
The force shaker is designed to reproduce a vibration environment. Qualification tests on MEMS components and small assemblies can be reproduced under controlled conditions using a wide frequency band. The shaker operates in the frequency range of 5 Hz to 10 kHz using a sine or random input waveform, converting an electrical current into mechanical force. It is mainly used for the testing of inertial MEMS sensors including modal investigation and vibration stress testing under varied environmental conditions. The system includes a temperature-controlled environment for a range of −40 °C to 180 °C.
Shock Test Machine Avex SM-105
The shock machine is used in the design and destructive drop testing of MEMS components, ASICs, hybrids, and complete assemblies of up to 22 kg. Shock testing within the range of 3g to 30,000g can be performed together with half sine, sawtooth and square wave pulses.
2 Axis Positioning Table
The IX-Blue EVO20-TC is a high precision two-axis positioning and rate table equipped with temperature control. It is aimed at testing and calibrating MEMS sensors, inertial systems and components such as multi-axis accelerators and gyroscopes. The system includes a temperature-controlled environment for a range of −40 °C to 80 °C.
The custom-built vacuum chamber with dimensions of 8”×8”×8” is constructed from 1 inch thick clear acrylic. The chamber is rated for vacuum levels down to 0.1 torr and is helium leak tested to 10-8 atm-cc/sec range. It also includes a 2.75” optical window with an anti-reflective coating for optical MEMS characterisations. The vacuum chamber is a useful tool for the analysis of air pressure dependence on sensor performance (ex: quality factor).
Electrical and Mechanical Microprobing
Cascade Probing Station with temperature control together with standard and RF differential probes
Micromechanical Testing Station
The Femtotools FT-RS1002 is a high precision three-axis nano-manipulation unit used to probe various micro mechanical structures. The instrument is designed to perform highly accurate probe-based force-position-time measurements which enable a large number of testing modes. Typical modes include compression/tensile testing, adhesion force testing, actuation force testing, deflection range testing, and distance and topography measurements.
