说明：  电子产品的轻薄小巧化发展，致使电路板的布局也越趋紧凑，3mil的线宽与线距及高频板应用已非常普遍。 面对日益精密的电路板，传统的菲林尺等抄板手段已不能保证其精度与效率。 下面为大家介绍一种最方便最高效精准的抄板方法，只需要你稍有PROTEL电路基础就能轻易掌握。
(Slim development of electronic products, resulting in circuit board layout is also becoming more compact, 3mil line width and line spacing and frequency board applications has been very common. The face of increasingly sophisticated circuit board, the film foot traditional means of copy board can not guarantee its accuracy and efficiency. Here I will introduce one of the most convenient and the most efficient and accurate copy board, only slightly PROTEL circuit basis can easily grasp.)
