课程笔记
第12章 Coverage and Gaps
微电子封装笔记来源覆盖、章节映射和资料边界说明。
考试要会什么
- 知道每个正式章节分别来自哪份 Lecture、practice、past exam 或考前资料。
- 知道哪些内容是 slides-backed，哪些只是 exam-signal，避免把学长资料当官方定义。
- 知道哪些资料被明确排除，尤其是
final_exam中的 slides。
一句话记忆
这页不是知识点正文，而是整套笔记的“来源账本”：以后补资料、查缺口、追溯某个结论都从这里开始。
来源等级说明
| 等级 | 含义 |
|---|---|
Slides-backed | 主线 封装/slides 有明确支撑 |
Slides + Exam-backed | slides 有基础，practice/exam 确认考法 |
Exam-signal | 考前/学长资料提示高频，但正式定义仍需回到 slides |
Background-only | 教材或背景资料，仅作术语校对 |

明确边界
final_exam中的 slides 不纳入本套笔记，因为用户已经说明不用管。- 学长笔记可作为高频信号，但不作为最高优先级定义来源。
- 正式笔记没有逐页翻译 PPT，也没有整页截图。
- 图片采用重画 SVG，服务考试图示和比较题。
仍可后续加强的地方
- 如果老师发新的 final feedback，应更新
Exam_Point_Map.md。 - 如果需要更贴近原 PPT 图，可从 PPTX media 中挑选非整页图片补进
assets/。 - 如果考试明确给 formula sheet，应把 thermal calculation 章节再压缩成公式速查版。
