You may distribute it and/or modify it under the terms of either the version March 05 2020 1. Introduction The KiCad PCB Calculator is a set of utilities to help you find the values of components or other parameters of a layout. The Calculator has the following tools: Regulators applications where high levels of assurance are required and service is essential. PCB Types In IPC-6012B there are also 6 Types of PCB defined: Printed Boards without plated through holes (1) 1 Single-Sided

并实时管理飞线指示 （飞线） 丢失的布线。 PCB元素（布线，焊盘，文本，图纸……）的显示可自定义： 完整或边框。 有无布线间隙。 对于复杂电路，可以选择性地隐藏层，区域和元件的显示以便在屏幕上清晰显 示。 可以高亮显示网的布线以提供高对比度。 封装可以旋转到任何角度，分辨率为0.1度。 Pcbnew 包含一个封装编辑器，可以编辑 PCB 上的单个封装或编辑库中的封 装。 封装编辑器提供了许多省时工具，例如： KiCad 封装库，作为 Github 存储库在线存储 旧版 - 旧式 KiCad 封装库（.mod 文件） Eagle - Eagle封装库（包含 .fp 文件的文件夹） Geda-PCB - Geda PCB 库 注意 您只能在本地磁盘上写入 KiCad .pretty 封装库文件夹（以及这些文 件夹中的 .kicad_mod 文件）。 所有其他格式都是只读的。 允许在不同的库中具有相同名称的封装。 如果没有加载项目文 件或项目路径中没有封装库表文件，则会创建一个空表，可以对其进行编辑， 然后将其与板文件一起保存。 当在项目特定表中定义条目时，包含条目的“fp-lib-table 文件”将被写入当前打 开的 PCB 的文件夹中。 2.3.3. 初始配置 第一次运行 CvPcb 或 Pcbnew 并且在用户的主文件夹中找不到全局封装表文 件“fp-lib-table”，Pcbnew 将尝试复制存储在系统的 KiCad
