1. Scan the upper and lower surfaces of the circuit board, there are two BMP pictures.

　　2. Open the copy software QuickPCB2005, click "File" and "Open the bottom diagram" to open a scanning picture. Use Pageup to amplify the screen, see the pad, place a pad in PP, see the line and press PT to walk ... Just like a child drawing, draw it in this software, click "Save" to generate a B2P file.

　　3. Click the "File" and "Open the bottom diagram" to open another layer of scanning color map;

　　4. Click the "File" and "Open" to open the B2P file saved in front. We see the just copied board and stacked on this picture -the same PCB board, the hole is in the same position, but the line connection is different from different line connections. Essence Therefore, we according to the "Options" - "layer settings", here to turn off the displayed lines and silk prints, leaving only a multi -layer perforated.

　　5. The excessive hole on the top layer is in the same position as the perforated on the bottom picture, and then the bottom line is sufficient like a childhood drawing. Click "Save" again -at this time the B2P file has the top and bottom layer information.

　　6. Click "File" and "Export as a PCB file" to get a PCB file with two layers of information. You can change the board or send a schematic diagram or directly send the PCB mode of production
