Taxi Test Stand
Every taxi passenger expects a correctly calculated fare. This fare is calculated by the on-board taximeter based on the distance travelled and the idle times. These taximeters have to be calibrated and verified periodically. The measurement technique of the three roller test stands used for this calibration at the Berlin-Brandenburg State Office for Metrology and Verification is fundamentally modernized and their handling significantly simplified.
Double Substitution Test Bench
This test bench performs a semi-automatic microphone calibration. Using the principle of double substitution the microphone under test is compared with a reference microphone at different configurable sound levels and frequencies. The test bench resides in an anechoic room.
Wheelchair Simulator
Feel the daily challenges of in mobility disabled people. Visiting the Science Center Medical Technology in Berlin you may try their wheelchair simulator and virtually explore a course near the Brandenburg Gate with ramps, bridges, curbs and cones. To ensure a high reliability for the audience and to simplify future software updates the control software is remade from scratch.
Temperature-Rise Tests for Circuit Breakers and Switchgears
The temperature rise of any part of circuit breakers and switchgears at rated normal current shall not exceed the temperature-rise limits specified in various standards. This test bench sources the DUT with a current up to 10000A and monitors up to 100 selective temperatures. If one temperature exceeds its limits, the test is shut down automatically.
Chip on Submount/CoS Test Bench
An already existing CoS (Chip on Submount) test bench for acquisition of laser diode characteristics is duplicated. The underlying test concept and the measurement techniques used for data acquisition are both basically modernized, giving a way to measure laser diodes much quicker and more efficiently while optimizing the stability of the whole test process.
Turbine Disc Centrifuge Test
An already existing test bench for turbine discs used in airplanes and its measurement technique is upgraded. The result is a free configurable data recorder for up to 100 channels of different measurands (temperature, pressure, revolution speed) with the additional ability to stabilize the pressure on several points within the test bench using PID algorithms.
Collinear Test Bench for Surface Resistance Measurement
This test bench is used for performing resistance measurements of semiconductor samples. The measurement principle follows the Four-Point Method and calculates the volume resistivity using the law of superposition.
Module Automat
Seamlessly integrated into the production process this test bench calibrates the quartzes of a wide variety of switching modules for home automation. The innovative and flexible software design allows the customer to create new test runs at any time and to integrate them dynamically.
200-Channel In-Situ Test Bed, Fitted in Climatic Chamber
This test bed allows long-time analysis of the electrical properties of solder connections. Up to 200 channels are scanned simultaneously, all integrated in a climatic chamber. The system is designed for a temperature operating range from -70°C to +250°C.
ICAMS Test Bed
(Isotropic Conductive Adhesive Measurement System)
This test bed aquires and analyses the long-term behaviour of isotropic adhesive bindings and other flip chip connection techniques concerning their electrical conductibility. Resistances below 10 milliohms have to be measured surely. (Photo: Fraunhofer IZM)
Exploration of Electromigration within PbSn Solder Bumps
The effect of electromigration within PbSn solder bumps is examined by this test bed. The goal is its verification by a resistance analysis in milliohms range. (Photo: Fraunhofer IZM)
Measuring the Light Efficiency of Organic LEDs/OLEDs
Efficiency and light intensity of up to 120 OLEDs are measured simultaneously over a period of several weeks or months. The results are used for evaluating different OLED technologies.
