compact camera module (CCM) alignment using six degrees of freedom

Adaptive Intelligence™

As the driving force in creating precision camera alignment with our Pixid systems, Adaptive Intelligence is an advanced software suite that uses database SPC embedded in our manufacturing systems to streamline the active alignment, assembly, and testing processes. The unique algorithm in our software uses feedback to constantly improve upon system performance.

Process information is collected from machine vision functions, the active alignment process, post-attach data, and yield trends. With machine vision data, the software identifies trends in manufacturing tolerances and identification of batch-to-batch variation that can impact the assembly process. Using active alignment data, the Adaptive Intelligence suite identifies trends in the focus performance of the lens as a function of position, and automatically adjusts process parameters in order to improve both the quality of completed camera modules (resulting in higher yield) and the speed of the alignment (resulting in higher throughput). Finally, by identifying trends in the magnitude and direction of adhesive shrinkage, the system may dynamically adapt those process parameters that compensate for the shrinkage in order to minimize the overall effect of the lens movement resulting from UV cure. This method enables higher yields compared to using static compensation factors.

Once the data is processed by the software system, the algorithm for aligning the camera lens to the sensor is altered to more closely reflect what has been learned from the collected data as part of a step-by-step, iterative alignment process. This process results in a far higher optical device performance and yield than any other manufacturing system on the market today.
