Restriction PCB board is PCB copy board, It
is also PCB clone, which is PCB reverse
engineering of design. It is to
first withdraw the components on the PCB circuit board to make a BOM list, PCB
reverse engineering empty board into a picture, and reinstate it to a pcb board
drawing file through the copying software; computing the pcb board drawing file
to the PCB board factory to make the board ( PCBA), and then add parts which is exactly the same PCB circuit board
as the genuine PCB circuit board.
Any electronic product copy and electronic
product cloning can be completed through PCB copy board technology.
The motive of PCB copy is sometimes to
modify the PCB, which is to conduct
alter technology research on the designed PCB board. After mention to a
lot of information, the process of PCB reverse
engineering is outline as follows:
The first step is to get a PCB reverse engineering, first record the model, framework, and positions of
all crucial parts on paper, especially the direction of the diode, the tertiary
tube, and the management of the IC gap. It is best to use a digital camera to
take two photos of the location of essential parts. The present day pcb circuit
boards are getting more and more advanced. Some of the diode transistors are
not observed at all.
The second steg is to detach all the
components and take out the tin in the PAD hole. Wash the PCB with alcohol and
put it in the scanner. When the scanner scans, you are required to raise the
scanned pixels slightly to get a clearer image. Then slowly sand the top and
bottom layers with water gauze paper till the copper film is bright, put them
in the scanner, start PHOTOSHOP, and scan the two layers individually in color.
The third stage is to modify the contrast
and brightness of the canvas to make the part with copper film and the part
without copper film have a strong contrast, and then spin the second image into
black and white, and check if the lines are clear.
