Everett Charles Technologies Non Magnetic
Probes for Reliable Sensor Testing with Full Temperature Range
Everett Charles Technologies (ECT) expands its product portfolio with non-magnetic spring probes for test applications, which are based on the measurement of the earth′s magnetic field in the full ambient/hot/cold temperature range. ECT non-magnetic probes ensure accurate, reliable and repeatable measurement of the earth′s magnetic field and the yaw rate movement in any of the three axes without interference from the test probes.
ECT′s non-magnetic probes support typical navigation applications in smart phones or dedicated navigation devices for cars in the fast growing MEMS/sensor market. For the development of these probes ECT not only drew upon its long-term experience in spring probes and materials, but also the comprehensive expertise within Xcerra in MEMS/sensor testing. By combining these elements ECT is able to provide non-magnetic spring probes that meet the challenging requirements of tri-temp MEMS/sensor testing. Sensors that measure the earth′s magnetic field and the yaw rate movement must be tested in a benign environment. To test sensors reliably without interference from the test stimulus, any possible materials that might disturb the earth′s magnetic field are not allowed in the area around the device under test. In addition, since many applications are bound for the automotive market, the test probes need to withstand temperature of -55°C up to +85°C and in some cases up to 150°C.
Tony DeRosa, Product Manager, explains: “By leveraging off of the vast sensor test experience within Xcerra, we are able to develop non-magnetic spring probe solutions with extraordinary performance in an unmatched temperature range. Our non-magnetic probes have been already deployed in volume production, where the outstanding performance has been confirmed.”
