MEMS sensors are mechanical structure chips and easily damaged by shock or huge vibration. Sensor package trend is going to small size, and it is not easy to solder by hand on pcb to verify. In order to do sensor verification before FA process, it is necessary to use a tool to load the failed chips and use I2C/SPI to access sensor registers to check sensor function. This document introduces to use sensor fixture and toolbox for a simple sensor verify tool. It is easy to provide precise failed spec items by this tool and to speed-up FA process.
