PCB copy board process

Below illustrates the whole process of copy board:
If there is a 4 layer board, components are removed, clean surface, we want to copy it into the Multilayer pcb file, according to the following steps:
 
1, scan the top plate, save images, name is top. BMP, then set the scan DPI can be set according to different density, if set is 400 DPI.   

2, scanning the bottom plate, save images, name for bottom. BMP

3, the middle tier 1 with sandpaper grind, leakage of copper sheet, clean after scans, name for mid1. BMP

4, the middle tier 2 with sandpaper grind, leakage of copper sheet, clean after scans, name for mid2. BMP

 5, each image in the PHOTOSHOP level (selected pictures, guarantee the images into a level, it will look out of the line, and picture more easily and alignment), it suggested that the underlying figure do level image, make the system diagram is in the same direction, up and down the positioning hole.Note do not need to cut out the picture just in here, had better leave some rich, almost as long as the picture just a matter of the level.   

6, open the color copy board software, from the main menu "file" - > "open the BMP file, choose top. BMP file to open.

After 7, set DPI, can copy the top figure, choose the first layer to the top, and then began to put components, via, wires, etc.   

8, after the top put all things, save temporary files (instruction and help, it is through the menu or toolbar button on yourself to choose), name of top - 1. The DPB (among different time save the name suggest a number of names, such as top - 1. The DPB, top - 2. DPB, so avoid computer failure, destroyed the last file, but can also save a version of the file, reduce the loss, this is a proposal, see the personal interests).

9, close the current picture window (note that a can only open a picture, don't open multiple images).   

10, from the main menu "file" - > "open the BMP file", choose the underlying figure bottom. BMP, temporary files and then open the top - 1. The DPB, then find the top draw good figure and the underlying background is not aligned, press Ctrl + A key combination, put all the good figure yuan is selected, press on the keyboard up, down, left and right cursor keys or number keys 2, 4, 6, 8 whole mobile, choose several reference points and the corresponding point on the background, then you can choose the current layer to the bottom, A walk is the bottom line, welding plate, filling, etc., if the top is blocking the line of the bottom, how to do?Is very simple, but from the main menu select "options" "layer color Settings", it is ok to check points off the top, also the top screen printing can also be closed.After copying the underlying, save the temporary file for bottom - 1. The DPB, or save the PCB files for bottom - 1. The PCB, then the file is already a file alignment, combination of two layers.   

11, a process is the same as the middle layer copy board, repeat steps 9 ~ 10, the final output of the PCB file, is four layers together and objects of the same PCB figure.  

Color copy board software some shortcuts and PROTEL is same, can see software to help or instruction in the list of "shortcuts".  
In a word, software use basically does not need too much learning can get started.
