碩士 === 國立屏東科技大學 === 工業管理系所 === 100 === Multi-layer ceramic capacitors (MLCC) are widely utilized as an important part in various electric and electronic units. In general, the consumption of electrics such as mobile phones and digital TVs consist of at least 150 pieces of MLCC whose each manufacturing batch contains considerable amount to millions pieces. The pieces of MLCC are inspected from visual inspection machines to replace manual visual inspection. In order to improve the quality of visual inspection the Taguchi method is used to formulate the experimental layout via five pivotal parameters which are extracted from practical processes of manufacturing. Through this study, not only can the optimal parameter design for visual inspection machines of MLCC be determined, but also significant parameters that affect the quality of visual inspection of the MLCC can be obtained. Experimental results are provided to illustrate the effectiveness of this approach. Keywords: multi-layer ceramic capacitors; parameter design; Taguchi method; visual inspection.
