摘要(中)

因應近年來電子產品的發展方向朝著高性能及輕量化，IC晶片也隨之縮小，故IC設計技術面臨的挑戰越發艱難。在IC封裝設計階段，透過模流分析有助於進行預先評估及尋求最佳化方案。然而，進行模流分析前，需先將CAD模型轉換為實體網格，並利用求解器(Solver)進行計算。實體網格種類中，六面體網格(Hexahedron)雖然品質最佳，但自動化建構難度較高，通常需人工處理。由於六面體網格是以四邊形表面網格(Surface Mesh)構成，因此四邊形表面網格建構方法成為未來發展的重要課題。本研究旨在發展混合結構化與非結構化四邊形網格自動建構技術，將IC模型分割為多個區域，並結合自動化網格建構技術，根據模型內部精度的需求，可選用合適的網格尺寸和類型，提高IC模型模流分析的精確度和效率。本研究對網格建構方法的調整，除了修改自動化區域劃分(Automated Partition)中，區域資料關係的建立方式外，也排除不同種類網格未接齊的問題，整體上增加該方法的穩定性，使其可在大部分的IC CAD模型上順利搭建四邊形表面網格，並由網格建構及模流分析結果發現，各種網格建構方法均有優缺點，而混合型網格在整體品質和模流分析效率上取得較佳平衡，進一步說明本研究所提方法的可行性。

摘要(英)

In response to the trend of high performance and lightweight design in electronic products in recent years. IC chips have also been shrinking. Posing increasingly difficult challenges for IC design technology. During the IC packaging design phase, mold flow analysis helps to conduct preliminary evaluations and find optimization solutions. Before conducting mold flow analysis, CAD models must be converted into physical meshes, and calculations need to be performed using a solver. Among the various types of physical meshes, hexahedral meshes are known for their superior quality. However, automated construction is more challenging and typically requires manual processing. Since hexahedral meshes are composed of quadrilateral surface meshes, the construction method of quadrilateral surface meshes has become an important topic for future development. This study aims to develop a technology for automatically constructing mixed structured and unstructured quadrilateral meshes, dividing IC models into multiple regions, and combining automated mesh construction techniques. Depending on the accuracy requirements of the model, appropriate mesh sizes and types can be selected to enhance the accuracy and efficiency of the IC model flow analysis. In addition to adjusting the mesh construction method, this study enhances the stability of the approach by modifying the establishment of relationships in automated region partition and addressing issues related to incomplete connections of different types of meshes. This allows for the successful construction of quadrilateral surface meshes on most IC CAD models. Through mesh construction and flow analysis results, it is found that various mesh construction methods have their own advantages and disadvantages. The hybrid mesh achieves a better balance in overall quality and flow analysis efficiency. This further demonstrates the feasibility of the method proposed in this study.
