How to make PCB by yourself ?

PCB PCB copy board methods and procedures

The first step, to get a piece of PCB, the first record on paper all the vitality of good models, parameters, and position, especially diode, three machine direction of the tube, IC gap direction. Best to use digital camera photos of two vitality of the location.

The second step, remove all devices, and will remove the PAD hole in the tin. Clean the PCB with alcohol, then placed in the scanner, the scanner needs a little time to raise the number of pixels scanned in order to get a clearer picture, start POHTOSHOP, color screen surface to sweep way, save the file and print out for use.

The third step, water, paper yarn and the TOP LAYER BOTTOM LAYER two minor sanding, grinding to a shiny copper film, into the scanner, start PHOTOSHOP, two color ways were swept into. Note, PCB placed in the scanner must be straight across the tree level, or scanned images will not be able to use and save the file.

The fourth step is to adjust the canvas contrast, brightness, so that part of the copper film and copper film is not part of the contrast and then converted to black and white sub-figure check lines are clear, if not clear, repeat this step. If clear, the survival for the black and white BMP format TOP.BMP and BOT.BMP, If you find a problem with graphics can also be repaired and modified with PHOTOSHOP.

The fifth step, the two were converted to BMP format file format file PROTEL in PROTEL in the redeployment of two, as two of the PAD and VIA over the location of the basic coincidence, that did well the first few steps, if biased, then repeat the third step.

Sixth, the TOP layer of BMP into TOP.PCB, attention should be transformed into the SILK layer, that layer is yellow, and then you line it wants in the TOP layer description, and place the device according to the second step of the drawings. Unfinished after the SILK layer deleted.

The seventh step, the BOT layer of BMP into BOT.PCB, attention should be transformed into the SILK layer, that layer is yellow, and then you line it wants in the BOT layer description. Unfinished after the SILK layer deleted.

The eighth step, will TOP.PCB and BOT.PCB PROTEL transferred, merged into a graph on OK.

The ninth step, a laser printer TOP LAYER, BOTTOM LAYER transparencies were printed to (1:1 ratio), the piece of film into the PCB, the comparison is wrong, and if yes, you"re done .
