Engineering Design and Process Improvement of Switching Power Modules

[[abstract]]目前為止，所有電子式產品所仰賴的電力來源，仍是以直流電源供應為主。切換式電源，在直流電源供應體系裡，是最符合瞬息萬變的市場趨勢的一大分支。其特點是切換式電源的產品體積相對較小、重量較輕，符合客戶端對產品要求輕薄短小的市場趨勢；此外，更具有可應用在寬輸入電壓範圍之特性，加上高轉換效率，更擴大了應用領域。 切換式電源在工業與通訊領域上使用得相當廣泛，國內在切換式電源的市場上也具有相當程度的占有率。然而部分客戶對產品品質之要求日益增進，但卻對於產品價格錙銖必較，因此，如何使整體製造成本能更有效地受到控制或是降低，並且同時能提升原來產品之品質，便成為產品能否繼續維持競爭力的重要考量。 於此本文採用田口方法進行分析與改良，希望能以最低成本、最少實驗次數、最簡便的分析方法及現有資源條件下，進行新產品的開發與現有產品的回顧時，在整體製造流程上的有所改良並加以驗證。[[abstract]]So far, all electronic products rely on DC power sources. Switching power supply is the most adapt to changing market trends at the DC power supply system. Switching power supply products is characterized by a relatively small product size, lighter weight, consistent with the client to its lightweight product market trends. In addition, more can be used in wide-area input voltage range of features, combined with high conversion efficiency, more areas will be applied. Switching power supply in the industrial and communications was very widely used. Domestic manufacturers have a considerable market share in the switching power supply. However, some customers on product quality demands on the promotion, but for the price pinch pennies, it make the rapid growth in the continent have the opportunity to catch up. Therefore, how to make the overall manufacturing cost can be more effectively controlled or reduced, and also can improve product quality. Is already the product can continue to maintain the competitiveness of important consideration. In this study, Taguchi method is used to analyze and improve. Use the lowest cost, at least in the experiment, the simplest way, and consider available resources, production of new product development and existing product reviews, and makes the whole production has been improved and validated
