摘要

A wafer-level test system is proposed for a high-g MEMS accelerometer based on a probe station. To simulate a high shock on the packaged sensors, a physical stimulus is loaded on the dies using a micromechanics device. The probe-station controller is controlled by a MFC program developed within the Microsoft Visual Studio Platform. The controller is able to move with three degrees of freedom in performing the automated tests of wafers. A data acquisition board is used to receive output signals from the dies through a reliable contact between the probe card and pads. The test procedure runs a LabVIEW program for post-processing the acquired signals including evaluating computing sensitivity and other parameters. An analysis of the test results determines at the wafer-level whether the die is good. This method may be applied during manufacturing of the high-g MEMS accelerometers where the benefits are seen in reduced production costs and a shorter time to market.
