Abstract: The rapid development of technology has led to the increased embracing of portable consumer electronics, such as mobile phones, digital cameras, and notebook computers. The lens cameras installed in these electronics are indispensable, and the function and quality of lens cameras have gained increasing attention. This study examines the production processes of lens camera products, utilizing the production capacity indicator C_pm to develop an evaluation model. This approach seeks to determine the important product quality characteristic production processes that have a detrimental impact on lens camera product quality. This study then applies a Six Sigma MAIC product quality improvement process to analyze the reasons for poor product quality, utilizing the Taguchi experimental design to examine the optimal production parameters; this study attempts to control production process quality through applying controls to these parameters. Ultimately, this study attempts to utilize Six Sigma MAIC processes to continually improve the quality of lens camera production processes, helping companies to increase the quality of their lens camera products and improve their competitive positions.

Abstract: Consumer electronic products have become an indispensable part of living for people with the development of information technologies. Crystal oscillator, CXO, a frequency controlling component, which is needed by communication-related industries, is widely used in expensive electronic products like mobile phones, notebook computers and GPS for its outstanding features of stability in temperature and low wearing. In CXO products, wires of ill quality are very likely to lead to ill contact between signal connectors and gold wires on IC or broken wires, which would cause the whole IC-packaged product unable to work normally. This article, thus, will develop a model of assessing and testing process capabilities with process capability index, C_pl, specifically for the larger-the-better quality characteristic of wire process. The article will also provide the assessment procedure, whereby the industry can effectively evaluate whether the process capabilities of their products meet the benchmarks they are supposed to.
