摘要
　　本論文將以高接腳密度0.8mm-pitch與0.6mm-pitch板對板高頻電子連接器為研究對象，探討其特性阻抗(characteristic impedance)、傳遞延遲(propagation delay)，串音雜訊(crosstalk)等高頻電氣特性；研究的方式包括實驗量測與數值電磁模擬，並比較兩者的結果。本文希望能以板對板連接器為例，發展相關連接器的高頻電氣特性的量測技術與電磁分析方法，以作為連接器的設計與應用的依據。實驗量測部份包括連接器之高頻測試板的設計與製作、測試儀器的使用操作、測試系統的組合、量測結果的分析，使用的量測儀器主要為時域反射儀(Time Domain Reflectometry，TDR)，並配合IConnect分析軟體。理論分析部份主要是以Ansoft SPICE-LINK的商用電磁分析模擬軟體，說明如何建立模型、設定、運算、參數的萃取，與最後的電路分析。
　　本文分別從實驗量測與數值模擬各項電氣參數，發現具有相當程度的吻合，以及對變化連接器高度與grounding配置具有相同的變化趨勢，因此本文可以應用於高頻電子連接器的設計和提供連接器下游應用者的參考數據。

Abstract
　Electrical performance of a high-speed electrical connector has now become one of the most important issues in connector design and applications.In this thesis, we will discuss both simulations and measurements of the high-speed electrical characteristics of a 0.8mm-pitch board-to-board connector and a 0.6mm-pitch board-to-board connector. As will be discussed later, the three main high-speed electrical characteristics that are to be determined are characteristic impedance, propagation delay, and crosstalk. It is the goal of this thesis to display how the electromagnetic performance of the connector can be understood through both simulations and experimental measurements, and how to establish the capability of handling the electrical characteristics of high-density and high-speed connectors.
　The experimental measurements are carried out with a time-domain reflectometry(TDR), IConnect software, and a specifically designed testing fixture. The electromagnetic simulation of the connector’s high-speed characteristics is carried out with the commercial software package, Ansoft Maxwell Spicelink. The comparison between the simulation results and the measurement datas will be addressed.
　In this research, it is found that for some of the high-speed electrical characteristics, the experimental and simulated results agree with each other very well. Finally, we investigate the changes of connector’s high-speed electrical characteristics due to variation of connector’s dimensions and the ground assignments. It is found that the experimental and simulated results show similar tendency of changes.
