This presentation delves into the critical world of production testing for MEMS environmental sensors. As these devices play a pivotal role in the environmental monitoring in many situations (from industry, to homes, to hospitals), ensuring their correct performance is of vital importance. Manufacturers face several challenges in guaranteeing the accuracy and reliability of their sensors, whose production testing can be a complex and time-consuming process. As these devices are sensitive to multiple environmental factors and respond to various stimuli (pressure, temperature, humidity, gas, …), the key thing about their testing resides in the need to develop testing setups able to capture all the electrical and mechanical aspects of the sensor, simulating and controlling a multiplicity of environmental factors. The sensor-type specificities represent a second challenge: each sensor type might require unique testing procedures and hardware setup, and this customization can be time-consuming and costly. Finally, while many applications are requiring more accurate and sensitive devices (that means, very accurate test equipment too), achieving high-volume production requires test cost efficiency. We will showcase how the latest advancements in test equipment are revolutionizing the approach for MEMS environmental sensors, solving all these challenges.
