Products & Platforms: Camera
Module Align, Assembly
and Test (CMAT) |
The CMAT (Camera Module Align, Assembly and Test) platform is designed specifically for precision assembly and testing of digital camera modules and sensors. It is unique in that it uses AEi's 5 degree of freedom active alignment rather than the single degree of freedom alignment typically used. This provides significant improvements in performance for the camera modules produced as end-customer expectations of image quality continue to increase. Further, the minimum technical requirements of some camera and sensor applications simply cannot be met without 5 degree of freedom alignment. CMAT also provides substantial increases in manufacturing yield.

The
CMAT I station is a sensor alignment, assembly and test system for product and process development
and low to medium volume production. It is roughly
5-10 times faster than manual align, attach, and
test with significantly higher yields and product
performance. |
 |
The
CMAT II system is a sensor alignment, assembly and test manufacturing line for higher volume
production plus additional operations such as fully
automated material handling, automated adhesive
dispense alignment and validation using machine
vision, secondary UV cure for faster throughput,
full electrical test and image test, and laser
marking. It is roughly 2-3 times faster than CMAT
1 stations and achieves even higher yields. |

AEi has developed an extensive set of alignment and test algorithms for the CMAT
platform that are easily configured as needed for specific
products and applications using the FlexAuto control
software. Both MTF and multiple gradient focus algorithms
are utilized for fast and efficient setting of optimal
focus alignment during the assembly process. CMAT also
includes adaptable interface electronics to support
communication and control of camera sensors from a
variety of manufacturers. Many CMAT systems have
already been deployed, both for product/process development
and full production, in the past several years to
multiple
facilities in North America, Europe, and Asia.
