MEMS Inertial Test
Testing Accelerometers and Gyroscope Sensors in Three Axis.
Cohu´s inertial solutions enable high precise Gyroscope and Accelerometer test with best-in-class cost of test due to high parallelism and package flexibility. All Cohu stimulus modules guarantee high precision and velocity stability as well as high temperature accuracy. With use of our high efficient handler portfolio we can offer the ideal solution with optimized cost of test.
For high-g applications, Cohu offers stimuli up to 100g in all three axis and 45° angle. Due to our modular setup a fast and flexible change between stimulus axes for the full application coverage is possible.
Test solutions are available on Gravity, Pick and Place as well as High Parallel Batch Handling (BatchCarrier).
For Gravity and Pick and Place only one test setup is needed to stimulate the devices for low-g acceleration, gyroscope in all three axis (6DOF) and sinusoidal movement.
Cohu´s Batch Handling solutions provide the highest coverage of package size down to 0.8 x 0.8 mm with maximum parallelism and BatchCarrier density up to 250. With a maximum of 3060 signal lines, we enable low-g acceleration and gyroscope test in all three axis.
