PCB reverse engineering process flow

PCB is actually a printed circuit board without components, Then the printed circuit board with components is called PCBA. So following is the process of PCB board copy with components:

1. Scan a picture of the circuit board

Note: since there may be small chip elements under the large components, you can scan them first, remove the large elements, and then scan again.

2. Remove the components

Remove all components the tin from the pad hole on PCB.We start to scan it. According to the PCB board’s precision to get a clearer image. Start Photoshop, scan the screen printing surface in color mode, save the file, and print it for future use;

Note: pay attention to the polarity and direction of components when removing the board.

3. Make BOM

Refer to the circuit board picture in the first step, record the model, parameters, and positions of all components on paper, especially the direction of the diode, transistor, and IC gap, and finally make the BOM list;

4. Grinding plate

Polish the two layers of the top and bottom layers with water gauze until the copper film is bright. Put it into the scanner, start Photoshop, and scan the two layers in color;

5. Adjust the contrast and shade

ofWhat contrast the canvas to the part with copper film. Then turn the secondary image to black and white. Or check whether the lines are clear. If not, repeat this step. It clear, save the image as a black and white BMP file TOP. BMP and BOT.BMP. If there is a problem with the graphics, you can also use Photoshop to correct them.

6. Start the PCB reverse engineering software Protel

Transfer the scanned PCB board images into the file menu, convert the two BMP format files into PROTEL format files, and transfer them to the two-tier in PROTEL. If the two PAD and VIA levels basically coincide, it indicates that the first few steps are perfect, and if there are deviations, repeat the fourth steps.

7. Convert the BMP of the top layer into TOP

PCB Pay attention to convert to the silk layer, and then you line the top layer and place the device according to the drawing in step 2. Delete the silk layer after drawing.

8. Convert the BMP of the BOT layer into BOT

PCB The same as above is converted to the silk layer, and then you can draw lines in the BOT layer. Delete the silk layer after drawing.

9. Compose it into a graph

In Protel TOP.PCB and BOT.PCB Call-in.

 10. Print double-sided PCB board

Use a laser printer to print the top layer and bottom layer on the transparent film (1:1 ratio). Put the film on the PCB and compare whether there is an error. If it is right, a simple double-sided board will be made!

How to order PCB reverse engineerings service?

Scientific PCB reverse engineering customer order process:

The whole board reading service process includes the following steps:

1. Project consultation/quotation of PCB reverse engineering cost.

Customers provide their own demand for copying boards, the introduction of board type, expected time limit of copying boards and known information of related PCB boards, and communicate with our service or technical personnel to negotiate the price of copying boards.

2. The customer provides the original PCB board and deposit 50%

If the PCB board is sent by express delivery, please pay attention to the package to avoid damage.

3. Our company will copy the boards according to the needs of customers

Engineers divide work and cooperate. They work for customers in strict accordance with PCB reverse engineering process.

4. Please confirm the completion of the copy

We usually finish the PCB copy. Secretary will send a PDF document to the client, after the customer confirms the document. The boss officially sends all source files of the PCB clone.

5. Confirm the completion and settle the balance.

Client view documentation in detail. In case there are mistakes in some places. The engineer will correct it in time and then re-submit it to the customer for confirmation until my friends are satisfied.
