88, 88);box-sizing: border-box !important;overflow-wrap: break-word !important;">。单面、双面电路板和有些三层、四层的电路板都可绘制。比较复杂的电路板需要用如下方法绘制：首先把电路板的非元件侧用复印机复印下来，在此复印件下放上复写纸，用笔描复印件上的电路，可在图背面（元件侧）留下痕迹，再根据元件和元件侧的电路在同一面用不同颜色的笔画上连线和元件符号，就完成了电路板图。然后再据此翻出电原理图（例 见附图A—F）。这是个很麻烦的工作，用几天的时间绘一块电路板的电路图是常有的事，但有了这个图，修好了机器就可创造数以千、万元计的价值，还是值得的。对以后维修同类机器很有用。另外，对提高我们的维修水平也很有益处。</span><br style="max-width: 100%;box-sizing: border-box !important;overflow-wrap: break-word
