摘要(中) 本研究利用物理方式的真空濺鍍,將純銅與不鏽鋼導電金屬粒子沈積於非導電塑膠機殼的內部結構上,使該塑膠機殼具有電磁波干擾防護的功能;配合本研究在機殼內部設計特有的結構,搭配真空濺鍍的導電金屬濺鍍層,不但使塑膠機殼表面形成連續的導電層,還可在不影響系統整體強度的前提之下,降低相關電磁波干擾防護的整體機構開發成本,展現出相關產品機構設計的創新。
研究中,將設計概念與實驗比較項目導入產品,實際呈現於筆記型電腦機殼相關設計上,比較著不同的電磁波干擾防治工法,提出此研究的優勢與發展性,證明此設計手法可提供產業的機構解決方案。
最後經由國際規範等級的檢驗規格,針對實驗研究系統進行電磁波干擾防護檢驗,確認其可達到電磁相容安全規範的標準,再通過系統相關機械破壞性與非破壞性的實驗,確保機構設計手法的可靠度,以此完成實際產品作為最終的研究成果呈現。
摘要(英) This study utilizes sputter of the physics way (Physical Vapor Deposition, PVD) to plate in vacuum. Let conduct metal particle of copper and stainless steel deposits and accumulates on chassis structure of the non-conducting plastic, the function of making this plastic chassis have being protected electromagnetic interference, it would cooperate with this research in the peculiar structure of chassis design; not only make the plastic chassis surface to form continuous electric conduction layer, It can also be under not influencing the prerequisite of the whole intensity of the system. The whole project’’s development has cost reducing relevant electromagnetic interference protecting, show the innovation that the relevant product designs.
While studying, it designs the concept and comparative project of experiment into the products, and will appear and correlated with designing in the note type computer chassis actually. The different preventing and curing processes have compared for electromagnetic interference protecting, propose the advantage and expansionary of this research. It proves that can offer the organization solution of the industry to design tactics in this.
Standardize the inspection specification of the grade via world finally. Study the system and carry on the electromagnetic interference protecting and examining to the experiment. To confirm it reaches the electromagnetic compatibility standard, and then through the relevant mechanical destructiveness and non- destructive of the system experiment. The guarantee the organization designs the reliability of the design tactics, so as to finish the real products and appear as the final research results.
