Wafer Bonder
AML
Wafer bonding has found many applications in the field of MST, MEMS and micro engineering. These include the fabrication of pressure sensors, accelerometers, micro-pumps and other fluid handling devices. The process is also used for first-order packaging of silicon microstructures to isolate package-induced stresses. The OAI AML Wafer Bonder facilitates both the alignment and bonding to be performed in-situ, in a high vacuum chamber. For anodic bonding the wafers are loaded cold and heated in the process chamber. For high accuracy alignment the wafers are aligned and brought into contact only after the process temperature has been reached, thus avoiding differential thermal expansion effects which can compromise alignment. The AML Wafer Bonder is excellent for anodic bonding, silicon direct and thermal compression bonding applications. These features enable the bonder to be used with virtually any processing tool.

Tactical Grade Inertial Measurement Unit (IMU)
ADIS16490 iSensor
The ADIS16490 iSensor® device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the ADIS16490 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyroscope bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements. The ADIS16490 provides a simple, cost-effective method for integrating accurate, multiaxis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The SPI and register structure provide a simple interface for data collection and configuration control.

High Sensitivity ICP® Accelerometers
High sensitivity ICP® accelerometers are specifically designed to enable the detection of ultra-low-level, low-frequency vibrations associated with very large structures, foundations, and earth tremors. These sensors typically possess exceptional measurement resolution as the result of its comparatively larger size, which furnishes a stronger output signal and a lower noise floor. All units are hermetically sealed in a titanium or stainless steel housing. Models that include a 2-pin, military style connector provide the added benefit of being electrically case isolated for superior RF and EMI protection.
