商品描述

This is the first edition. A second edition of the book has been released that you might prefer. Search Amazon.com for it or refer to www.ultracad.com for more information. Finally! For the first time, here is a complete, thorough analysis of the relationships between PCB trace (and via) currents and trace temperatures. All in one place! Brooks has been looking at these relationships since the mid '90s. And he has assembled 20-plus years of knowledge into these pages. Starting with a historical background, this book covers: (a) PCB materials (copper and dielectrics) and the role they play in the heating and cooling of traces; (b) The IPC curves found in IPC 2152; (c) Equations that fit those curves; (d) Computer simulations that fit those curves and equations; (e) Sensitivity analyses showing what happens when we vary the environment (adjacent traces and planes, changing trace lengths, thermal gradients, etc.); (f) Via temperatures and what determines them; (g) Via current densities; (h) Fusing issues, what happens when traces are overloaded, and (g) a chapter showing how unevenly traces heat, even at low temperatures. There are supplemental chapters or appendices on measuring the thermal conductivity of dielectrics and measuring the resistivity of copper traces (and why many prior attempts have been doomed to failure.) And there is even a chapter on whether Industrial CT Scanning might replace microsections for measuring trace parameters. Never before has such a thorough compendium been available, especially so conveniently.

商品描述(中文翻譯)

這是第一版。本書的第二版已經發布,您可能會更喜歡。請在 Amazon.com 上搜尋或參考 www.ultracad.com 獲取更多資訊。終於!這是第一次完整、徹底分析 PCB 路徑(和通孔)電流與路徑溫度之間關係的著作,所有內容都集中在這裡!Brooks 自 90 年代中期以來一直在研究這些關係,並將超過 20 年的知識彙集在這些頁面中。本書從歷史背景開始,涵蓋以下內容:(a) PCB 材料(銅和介電材料)及其在路徑加熱和冷卻中的作用;(b) IPC 2152 中的 IPC 曲線;(c) 符合這些曲線的方程式;(d) 符合這些曲線和方程式的計算機模擬;(e) 敏感度分析,顯示當我們改變環境(相鄰路徑和平面、改變路徑長度、熱梯度等)時會發生什麼;(f) 通孔溫度及其決定因素;(g) 通孔電流密度;(h) 融合問題,當路徑過載時會發生什麼,以及 (i) 一章顯示即使在低溫下,路徑加熱也會不均勻的情況。還有補充章節或附錄,介紹如何測量介電材料的熱導率和測量銅路徑的電阻率(以及為什麼許多先前的嘗試注定失敗)。甚至還有一章探討工業 CT 掃描是否可能取代微切片來測量路徑參數。如此徹底的彙編以前從未出現過,尤其是如此方便。
