Explain the PCB copy process:

The first step, get a PCB, first record on paper the model, parameters, and location of all the components, especially the diode, the direction of the three machine tube, the direction of the IC gap.

Step 2, remove all devices and remove the tin from the PAD holes. Clean the PCB with alcohol, then put it into the scanner, start POHTOSHOP, sweep the silkscreen surface in color, and print it out for backup.

Step 3, lightly sand the TOP LAYER and BOTTOM LAYER layers with water yarn paper until the copper film is shiny, put it into the scanner, start PHOTOSHOP, and sweep in the two layers separately in color.

Step 4: Adjust the contrast, lightness and darkness of the canvas, so that the part with copper film and the part without copper film are in strong contrast, then turn the secondary image to black and white, check whether the lines are clear, if not, repeat this step. If clear, save the figure as black and white BMP format files TOP.BMP and BOT.

Fifth, convert the two BMP format files to PROTEL format files respectively, and transfer into two layers in PROTEL, if the position of PAD and VIA over the two layers basically overlap, it shows that the first few steps are well done, if there is deviation, repeat the third step.

Sixth, convert TOP. BMP to TOP. PCB and place the devices according to the drawing in the second step.

Seventh, convert BOT. BMP to BOT. PCB.

Step 8, transfer TOP. PCB and BOT. PCB in PROTEL and combine them into one drawing.

Step 9, use laser printer to print TOP LAYER, BOTTOM LAYER on transparent film (1:1 ratio), put the film on that PCB, and compare whether there is a mistake.

“If you have any demand for copy/change board, we will give you the most reasonable quotation immediately according to your specific requirements, and welcome you to call and visit us for project cooperation negotiation.

Warm tips:
1, where the company for circuit board cloning business customers, must have a legal PCB design copyright source statement, in order to protect the legitimate rights and interests of the original PCB design copyright owners;
2, recently there are more companies on the market with “PCB copy services”, in order to avoid unnecessary losses; to ensure your interests; please confirm the existence of the company or has been revoked;
