Description: 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.
