Processes & Tools: Precision Motion

AEi uses moderate to very high precision motion stages from a variety of suppliers to meet the precision automation requirements of our customers. As with other tools we use, AEi takes an open architecture approach in utilizing motion stages and motion control technology.

Application Examples:

• Camera Sensor Alignment and Test
• MEMs Assembly
• Vision Guided Stent Welding
• Planar Photonics Device Alignment and Test
• Single Channel Photonics Device Alignment and Assembly
• Automated Wafer Handling and Inspection System
• Component Placement and Liquid Dispensing Station with Machine Vision
• Precision Vision Guided Alignment of Macro Lens
• Vision Guided Thermal Grease Dispense

Products & Platforms:

• Photonics Module Align, Assembly and Test (PMAT)
• Camera Module Align, Assembly and Test (CMAT)
• FlexAuto
• Vision Guided Laser Tool (FlexLase)

Features & Benefits of AEi Implementation:

• Open architecture approach allows for selection of optimal specific motion control components and algorithms for a given application
• Extensive experience with all aspects of motion control implementation
• Access to a wide range of motion control alignment algorithms such as raster scan, spiral scan, line scan, box scan, and both 2D and 3D downhill simplex
• The FlexAuto software platform seamlessly integrates machine vision, motion control, and operator interface for flexible automation

We have the experience and ability to select and utilize the most effective motion components for a given application from a variety of sources, including the right drive electronics, motion stages, and motion control algorithms. We work primarily with servo motion control, but also use stepper motor control and pneumatic actuation for less demanding needs. We have implemented as many as 32 motorized axes of motion with encoder resolutions as low as 5 nanometers and with travel speeds as fast as 2 meters a second.
