　　無鉛銲錫相關之知識日新月異，為了達到更有效率的學習，一個架構清晰且使用方便的知識庫有其必要性。本研究以知識管理為出發點，將目前已經發表在文獻上之無鉛銲錫系統彙整成為一有系統的知識庫，並以網頁的形式來呈現此知識庫。此外，本研究也針對具有發展潛力之Sn-Zn-Ag-Al-Ga五元無鉛銲錫合金，進行抽線性與機械性質加以探討。

　　本研究所建立知識庫之架構主要由十一個項目所組成，首先將無鉛銲錫分為二元、三元、四元、五元與多元無鉛銲錫合金系統五個項目，接下來則為銲錫合金之性質比較圖、二元合金系統之相圖、世界無鉛銲錫專利表、重要名詞之解釋、單位換算之功能以及參考資料等六個項目，並且在知識庫內提供一搜尋系統讓使用者能夠快速地查詢無鉛銲錫合金之性質。與其他的學習管道比較，本知識庫網站不僅便於增修、更新與擴充，並將所蒐集之無鉛銲錫性質製作成圖表，讓使用者能夠快速地對不同成分之無鉛銲錫合金性質作比較。本研究所開發之搜尋系統則具備快速查詢的功能，能夠針對特定合金系統之特定性質作快速搜尋，也能夠一次對所有銲錫合金之特定性質作搜尋，如此大大地增加使用者的學習效率。

　　在五元無鉛銲錫合金方面，本研究著重於將Sn-Zn-Ag-Al-Ga合金抽線製成錫線，來探討合金之抽線成型性、抗拉強度、顯微組織與破裂模式。研究結果發現，只要抽線程序的設計恰當，其抽線成型性是相當不錯的。拉伸測試結果發現此合金的抗拉強度與伸長率皆優於鉛-錫合金，可將此合金製成線材來取代鉛-錫合金，但此線材產生的兩層結構使得手銲過程相當不便，在製作的程序上仍有改良的空間，如大量氣孔使其整體性質變差，因此後續五元合金製作成鑄錠到抽線的過程中須加上除氣的程序，以確保線材有良好的機悈性質，產品有穩定的一致性。

　　There are constantly new technologies and information generated in the field of Lead-free solder. In order to extract knowledge effectively, we need a knowledge-based system with a clear structure. In this thesis research, a lead-free solder knowledge-based system has been constructed in the form of web-sites. Besides, the formability for wire drawing and mechanical properties of Sn-Zn-Ag-Al-Ga solder alloy is also analyzed in this study.

　　The knowledge-based system in this study is composed of eleven parts, which are 2-elements, 3-elements, 4-elements, 5-elements, multi-elements lead-free solder alloys and properties contrast diagram, two phase diagram, worldwide solder patents, items explanation, unit transformation and references. The knowledge-based system also provides a search system for users to search data efficiently. Compared with other ways of knowledge acquisition, this system is more easily to be modified and updated. The property contrast diagrams help users to compare properties of different solder alloys more easily. The search system can search a specific property of one solder system, and it also can search a property of all solder system in knowledge-based system. This function can improve the learning efficiency.

　　This study focuses on the formability of the Sn-Zn-Ag-Al-Ga alloy for wire drawing to produce solder wire. It is found that through proper design of the wire drawing process, the solder wire of this particular alloy can be successfully drawn. The tensile tests reveal that the tensile strength and elongation of the Sn-Zn-Ag-Al-Ga are better than those of the Sn-Pb alloy. However, the wires are found to have the double-core structure, where the outer layer is very brittle. It is then concluded that degassing is required during the preparation of the ingots, which are subsequently drawn to wires of desired dimensions.
