中文摘要

This study is based on T Solar Cell Company. The company received customer complaints of the insufficient peeling strength caused by inappropriate welding processes, and these complaints later led to substantial compensation for customers. The company subsequently determined the optimized bus bar welding condition through the design of experiments (DOE) of the cell welding ribbon before mass production, which enabled the production line to further enhance their output yield after product launch. Because a solar cell module is expensive and not easy to rework, scrapping the entire solar cell module can cause high loss for a company. In the semiconductor industry, wafers and die units are extraordinarily costly; thus, DOE methodology can be applied to semiconductor industries to reduce process waste, improve output, and promote corporate competitiveness. In this study, the top three process factors affecting the quality of welding performance, namely iron welding temperature, heating-plate temperature, and welding time, were selected for DOE analysis, and each factor constituted three levels in the DOE construction. The results of statistical analysis revealed whether it had a normal distribution and referable value by verifying the results by employing an analytic model. The significance of the interactions between the three factors and between two factors was clarified. The effect of all three independent main factors on the output peeling strength was investigated. Subsequently, optimized welding conditions were determined using DOE analysis. Furthermore, a regression model was employed to prove the correlation between peeling strength and the solar cell module yield both before and after improvement. Suggestions for improvement made on the basis of the results of this study can be applied to corporate industries in the future for development and reference purposes in the solar cell industry.

英文摘要

本研究是以T太陽能公司為研究對象,針對T太陽能公司所面臨到焊接不良導致拉力不足而產生的客訴問題,當次拉力客訴最終衍生出高昂的賠償金。反思到工廠端如何在尚未量產階段,來透過實驗設計找出最佳銲帶的焊接條件,進而提升公司產出的良率。透過實驗設計挑選出前三大實驗因子:烙鐵焊接溫度、加熱底板溫度與焊接時間,並將其每個因子以三個水準做成本實驗設計架構,觀察其相關分布圖是否為常態分布,可驗證此模型分析所得到的結果是否具有參考之價值。並分析其三元因子間的交互作用,再分析其二元因子間的交互作用與其相關的顯著性,最後再分析其主因子間的顯著性,後續進行實驗分析來找出最佳焊接條件。最後採用簡單迴歸分析模型,將改善前與改善後,拉力值與實際模組產出之良率進行迴歸分析。將其研究結果進行彙整,提出相關的改善與建議。對於未來太陽能產業之發展與參考。
