Steps To Copy PCB Boards

Steps To Copy PCB Boards


The first step is to get a piece of PCB, first on a piece of paper to record all the elements of the model, parameters, as well as the location, especially the diode, the direction of the compressors pipe, IC the direction of the gap. It is better to digital camera two pictures from a location.

The second step is to tear down all device and the PAD holes in the tin. PCB clean with alcohol, and then put into the scanner, the scanner to scan the time needs to be somewhat higher scan pixels, in order to get a clear image, start PHOTOSHOP, knocked screen printing surface into color way, save the file and print it out for later use.
The third step, water gauze paper will TOP LAYER and BOTTOM LAYER two layers of slight grinding, polishing to copper film, into the scanner, start PHOTOSHOP, knocked two layers respectively into in color mode. Pay attention to,PCB in put inside the scanner must cross straight trees, or scan images can't use, and save the file.
The fourth step, adjust the contrast of the canvas, the contrast, the copper film part of and not part of the copper film contrast, then the first figure to black and white, check whether the line is clear, if not clear, repeat this step. If clear, will survive for the black and white TOP. The BMP file format of BMP and BOT. BMP, if found problems graphics can also use PHOTOSHOP to repair and correction.
Fifth, the two BMP format into PROTEL format file, respectively in PROTEL transfer into two layers, such as a two layer of the PAD and the location of the VIA basic coincidence, suggests several steps before doing a good job, if there is a deviation, then repeat step 3.
Sixth, TOP. The TOP layer of BMP can be converted to PCB, be careful to into a SILK layer, the layer is yellow, and then you just at the TOP layer tracing, and drawing device according to the second step. After the draw will delete the SILK layer.
Step 7, BOT BOT layer of BMP can be converted to the PCB, be careful to into a SILK layer, the layer is yellow, and then you in BOT layer tracing it. After the draw will delete the SILK layer.
Step 8, TOP in PROTEL PCB and BOT. PCB paged, into a graph with respect to OK.
Step 9, use laser printer to TOP LAYER, BOTTOM LAYER respectively printed on transparent film (1:1 ratio), put the film on the PCB, compare the errors, if yes, you're done.
Other: if it is a multilayer and carefully polished inside lining, repeat steps 3 to 9, at the same time, of course, the naming of graphics is different also, want to be decided according to the number of layers, the general double panel is much simpler than a multilayer copy board, laminated copy plate prone to alignment, loOK so professional copy PCB board and carefully (including internal guide hole and guide hole is not easy to appear problem)..
