How to imitate PCB board and circuit board
, Get a piece of PCB, first recorded on the paper all the models of gas, parameters, and location, especially the diode, the direction of the three, IC gap direction. It is best to use a digital camera to take two pieces of the location of the photo. Now the pcb circuit board more and more advanced above the diode transistor some do not pay attention to simply do not see.
pcb board file to the PCB board to make board ( PCBA), and then marked on the components (according to BOM single purchase to the corresponding components) is the original PCB circuit board with the same PCB circuit board.
Remove all the devices and remove the tin from the PAD hole. Clean the PCB with alcohol and place it in the scanner. When scanning the scanner, you need to slightly raise the number of pixels to scan for a clearer image. And then use the water yarn paper to the top and bottom slightly polished, polished to the copper film shiny, into the scanner, start PHOTOSHOP, with two ways were swept into the color. Note that the PCB placed in the scanner must be horizontal and vertical, otherwise the scanned image can not be used.
Imitation PCB board PCB copy board, PCB copy board that is PCB cloning, PCB design is the reverse engineering. Is the first PCB circuit board components removed from the BOM single, the empty board scanned into a picture by the copy board software to restore the pcb board map file
