PCB circuit board copy(clone pcb) method and step

The first step, to get a piece of PCB, first recorded in the paper all the components of the model, parameters, as well as the location, especially the diode, the direction of the three tube, the direction of the IC gap. Best to use a digital camera to take pictures of two Zhang Yuan gas parts.
The second step, remove all the devices, and the PAD hole in the tin removed. With alcohol will PCB clean, then placed in the scanner, scanner when the need to slightly adjust the high number of scan pixels, in order to get a clear image, start POHTOSHOP, with color will screen printing swept into, save the file and print it out spare.
The third step, the water gauze will top layer and BOTTOMLAYER two layers of slightly polished, shiny polished to a copper film, into the scanner and Photoshop to start, with the color of the two layers were swept into. Note, PCB in the scanner must be horizontal flat straight, otherwise the scanned image can not be used, and save the file.
The fourth step, resize the canvas of the contrast, brightness, a part of the copper film and no part of the copper film contrasting, then ort chart for black and white color, check the lines are clear, if not clear, repeat this step. If clear, the survival for black and white BMP file format TOP.BMP and BOT.BMP. If it is found that the graphics problems can also use Photoshop to repair and correction.
The fifth step, two BMP format files were turned as Protel file format, in Protel transferred to two layers, such as two layers of pad and via the position substantially coincident, shows that the first few steps to do well, if there is deviation, repeat the third step.
Sixth, the TOP layer of BMP into TOP.PCB, attention should be converted to the SILK layer, that is, the yellow layer, and then you are in the TOP layer of the line is, and according to the second step of the drawing device. After painting the SILK layer deleted.
The seventh step, the BOT layer of BMP into BOT.PCB, pay attention to be converted to the SILK layer, that is, the yellow layer, and then you are in the BOT layer tracing line is the. After painting the SILK layer deleted.
The eighth step in the PROTEL TOP.PCB and BOT.PCB will be transferred, as a graph on OK.
The ninth step, using a laser printer will top layer, bottom layer were printed to the transparent film (1:1 ratio), the film into the piece of PCB, compare whether the error, if it's true and you're done.
Other: if it is the multilayer also carefully polished to the inside of the inner layer, and to repeat the third to ninth step, of course, the naming of the graphics is different, according to the number of layers, the double side board copy board to than many simple multilayer, multilayer board copy board prone to contraposition, so the multilayer board copy board to particularly carefully and be careful (which internal vias and non conducting through holes is prone to problems).
