When police, firefighters, and emergency medical personnel are called to the scene, their communication systems must perform flawlessly even under the most extreme conditions. To support the series production of a compact and rugged two-way radio control unit that can be worn directly on the wrist or arm and operated comfortably with a single finger, two new End-of-Line (EOL) test systems were recently developed from MCD Elektronik. As the device communicates wirelessly via Bluetooth Low Energy (BLE), high standards were set for quality assurance.<\/p>\n
At the heart of the systems there are two 19-inch test racks each featuring the implementation of a first-time used high-frequency adapter from our partner ATX Hardware, enabling the parallel and under specially shielded conditions testing of four DUTs. After contacting the DUTs, the systems perform an ultra-low quiescent current measurement – a particularly demanding task, as the device is powered by a coin-cell battery and the standby current must remain below 2 \u00b5A. This level of precision is achieved using a MCD developed 3-channel current measurement board. Originally designed for higher current ranges, it has now successfully demonstrated outstanding accuracy and repeatability in the microampere range.<\/p>\n
In addition to quiescent current measurement, the systems verify the establishment of the BLE connection, the electrical functionality of control buttons and status LEDs. Control are handled by Siemens PLCs, MCD USB hubs and MCD’s central software tool “TestMate”. Thanks to the MCD Toolmonitor “Modbus”, the PLCs can be controlled and parameterized directly from within MCDs “TestMate”. This significantly simplifies engineering, eliminates the need for PLC program modifications and provides a more flexible and efficient test environment for production.<\/p>\n
The result was a high-performance testing solution that combines the highest quality standards with efficient mass production testing, and which was recently delivered successfully. Thanks to the entire MCD team, whose expertise and dedication have once again ensured customer satisfaction.<\/p>\n","protected":false},"excerpt":{"rendered":"
