Processes & Tools: Active Alignment for Camera Modules and Opto-Electronics
Active alignment measures key performance attributes in a product during manufacturing enabling dynamic adjustments of the manufacturing process to create products with optimal performance. This is different from passive alignment, where components align to each other based on the accuracy and precision of mechanical fixturing, tooling, and motion stages in the manufacturing process. AEi typically implements a multi-axis, also called a multiple degree of freedom, approach to active alignment. This allows us to compensate for variation of component tolerances in multiple physical dimensions for best overall results.Application Examples:
- Camera Sensor Alignment and Test
- Planar Photonics Device Alignment and Test
- Single Channel Photonics Device Alignment and Assembly
Products & Platforms:
- Photonics Module Align, Assembly and Test (PMAT)
- Camera Module Align, Assembly and Test (CMAT)
Features & Benefits of AEi Implementation:
- Open architecture approach allows for selection of optimal instrumentation and sensors for a given application
- The FlexAuto software platform allows measurements and dynamic adjustments based on these to be easily configured
- Product performance and yield are almost always greatly improved using active alignment versus just passive alignment
While active alignment requires additional instrumentation and sensors, etc., it may not necessarily be more expensive than passive alignment. Active alignment supports the use of less accurate (and less expensive) fixturing and motion stages in a given manufacturing station.
As with other tools we use, AEi takes an open architecture in utilizing active alignment. We have the experience and ability to select sensors and instrumentation to include in our flexible automation solutions to best meet a given application’s needs. This includes a wide range of optical and electronic instruments, force transducers, flow transducers, and temperature transducers. Our reconfigurable station control software is used to acquire the measurements and optimize the manufacturing process to make active alignment practical and cost effective.
