Some Insights About Camera Module Alignment

By Annette Bishop


Digital cameras are becoming more common to consumers due to their capability to produce quality pictures and other features within them. Their increased applications in mobile automobiles and in mobile phones is increasing innovations in lens quality, power consumption and in pixel density. The increase in performance of the camera module alignment has resulted to increase in the assembly requirement techniques.

The increase in demand of camera aided devices like mobiles have led stations improve their innovations in pixel density and in the quality of the lenses. People are seeing it better to store information in picture form. This alignment techniques have also changed the techniques involved during assembly time.

The other component is the optically aligned lens barrel assembly that is responsible for good capture. Traditionally during the manufacturing process, a threaded lens barrel was inserted in the housing and the image was monitored on a video screen for positioning. This process enabled the manufactures to perform the lens positioning in only one dimension.

One is the sensor unit which is carefully fitted on a circuit board and a lens barrel assembly which is optically aligned. Traditionally the manufacturer could only align the lens assembly to sensor in only one dimension but in the new modules, the position of two linear and two rotational axes is greatly considered. In order to achieve a clear sharp image, accurate arrangement of the lens to sensor need to be done in five degrees of freedom.

The improved lens position to the sensor has enabled the consumer gadgets produce to clear images with higher qualities. The technology has led stations tend to ares of high volume productions offering the manufactures with a number of functions like the image testing. It even have eliminated some unnecessary components in the products thereby minimizing cost and improving accuracy and performance.

The camera module alignment has improved the consumers products by enabling them have good features. It also has a number of benefits to customers with gadgets using the technology. It has reduced the accidents in automobiles.
