柔性印刷電路板連接器之掀蓋改良設計
Modified Lid Design for Flexible Printed Circuit Connector
摘要
本文主要撰寫在英業達股份有限公司擔任機構工程師實習一年的內容與心得，包含機構工程師相關的知識、筆記型電腦的相關製程介紹等。除此之外也包含了與其他部門或廠商溝通合作時需要注意事項，避免無效的溝通及失敗的結果。 隨著科技迅速發展，電子產品的尺寸逐漸縮小且更為輕薄，同時對於傳輸速度的要求也日益提升。特別是AI技術的蓬勃發展及AI PC的應用，讓市場對於柔性印刷電路板(Flexible Printed Circuit, FPC)連接器的需求也日益增加。然而，受限於窄小的空間，FPC連接器的設計需要同時考量尺寸及強度，避免因為強度不足導致產品容易損壞的問題。 本研究聚焦於FPC連接器的掀蓋轉軸因為應力集中容易損壞的情況進行分析，模擬外力對FPC連接器掀蓋使用垂直向下力量為5牛頓(5N)，並透過田口方法及Ansys Workbench模擬進行最佳化分析，獲得優化過後的數據參數，為後續產品設計提供改進方向。研究結果顯示，最佳設計參數組合為A3掀蓋材質為PA6T RA230NK、B3轉軸直徑為0.36 mm、C1轉軸倒圓角為無倒角、D3掀蓋厚度為0.41 mm。這些參數的選擇有效降低了掀蓋轉軸處的應力值，最佳解的整體數據較原始設計降低了約8.22%應力值，從而顯著降低因應力集中導致的掀蓋轉軸損壞風險。

This paper primarily documents my one-year internship experience as a mechanical engineer at Inventec Corporation, including relevant knowledge related to mechanical engineering and an introduction to the manufacturing processes of notebooks. Additionally, it covers key considerations when communicating and collaborating with other departments or suppliers to avoid ineffective communication and unsuccessful outcomes. With the rapid advancement of technology, electronic products are becoming increasingly smaller and thinner, while the demand for faster data transmission continues to grow. In particular, the booming development of AI technology and the application of AI PC have significantly increased the market demand for Flexible Printed Circuit (FPC) connector. However, the limited space available imposes constraints on FPC connector designs, requiring careful consideration of both size and strength to prevent product damage due to insufficient structural integrity. This study focuses on analyzing the issue of stress concentration that can lead to damage in the shaft of FPC connector lids. The simulation applies a 5N downward vertical force to the FPC connector during lid opening. Optimization analysis is conducted using the Taguchi method and Ansys Workbench simulation to obtain optimized parameter data, providing improvement directions for future product design. The results indicate that the optimal design parameters are: A3 lid material PA6T RA230NK, B3 shaft diameter 0.36 mm, C1 shaft fillet no fillet, and D3 lid thickness 0.41 mm. The selection of these parameters effectively reduced the stress values at the hinge area of the lid. The overall data of the optimal solution showed approximately an 8.22% reduction in stress compared to the original design, significantly lowering the risk of hinge failure caused by stress concentration.
