Chandler, AZ — Timing precision, accuracy and tol- erance to harsh environments are essential to ensur- ing precise operation in today’s highly advanced automotive systems. Microchip Tech nology has unveiled its new DSA family of automotive-grade microelectromechanical systems (MEMS) oscillators that are designed to provide 20 times greater relia- bility, 500 times greater tolerance to shock, and five times greater vibration resistance than traditional quartz-based crystal devices. The DSA family also includes a multiple-output MEMS oscillator. Timing solutions with tight frequency stability

tor processes, providing the same reliability and stability as integrated circuits. Crystal oscillators rely on the thickness of the crystal blank inside the oscillator, making them susceptible to vibration damage with longer lead times and fixed frequen-


cy. This can delay product development or release times if a customer needs to make a last-minute frequency change. MEMS oscillators achieve fre- quency through programming, giving them flexi- bility to quickly support new frequencies with shorter lead times, as well as to ramp volume to help customers to meet product launch schedules. As a dual-output MEMS oscillator, the


DSA2311 can replace two crystals or oscillators on a board. The device addresses board space limits, saves costs and simplifies the design process, enabling customers to manage supply and consoli-


over a wide temperature range are critical for such applications as advanced driver assistance systems (ADAS), lidar, in-vehicle Ethernet, and autonomous driving. Available in small package sizes, Microchip’s new DSA1001, DSA11x1, DSA11x5 and DSA2311 offer high tolerance to mechanical shock and jarring, and stability in harsh environments over a frequency range of 2.3 to 170 MHz. The devices are AEC-Q100-qualified with ±20 ppm stability over temperatures ranging from –40 to +257°F (–40 to +125°C). MEMS oscillators are built entirely with standard semiconduc-

Vacuum Tweezer Solutions


For nearly thirty years we have been a leading supplier of vacuum handling solutions to the world’s high technology fi rms. Our patented ESD safe products are used by CLASS I clean room personnel, electronic assemblers, semiconductor manufacturers, the optics industry and universities around the world. Our success comes from developing innovative manual vacuum handling tools and pick-up tips based on customer requests and customer feedback. These tools provide customer specifi c solutions that make assembly and processing operations more productive and ergonomic. Parts range in size from 0.13mm (0.005”) up to 300mm (12.0”) for easy handling.


• Self-contained vacuum tweezers


• Portable, battery-operated continuous vacuum handling systems


Artec Ray 3D laser scanner With the ability to scan from


distances of up to 361 ft (110m), the scanner offers submillimeter dis- tance accuracy and excellent angular accuracy. Data capture is very clean when compared with other 3D scan- ners of this type and it keeps noise levels to a minimum. As a result, post-processing time is greatly reduced. Scanning with Artec Ray is


easy. Users need only place it on a tripod in front of the object they wish to scan and press the button. Portable and compact, the laser scan- ner can be set up easily indoors or outdoors. Its internal battery lasts up to four hours. The scanner also comes equipped with software, Artec Studio. Processed scans are exported to Geomagic Design X. Artec Ray can be paired with


Eva or Spider handheld Artec scan- ners to scan hard-to-reach areas, such as the interior of vehicles, or to add intricate detail to a large-scale
