13 years of PCB board copying experience

Zicheng Electronics is one of the earliest companies engaged in PCB reverse development and design in China, with more than 13 years of PCB copying experience. Zicheng Electronics has established an advanced PCB board copying laboratory, purchased board copying machines and software, and set up a board copying team. Every year, we handle nearly 1000 PCB copy board cases, and the success rate of copy board cases we take over is guaranteed. Rich experience in copying board on the basis of guaranteed success rate, but also can finish the work of copying board faster. High efficiency and high success rate make subroutine electronics highly praised in the industry.

Scientific PCB copy board process

Show the customer the whole process of PCB copying service, including but not limited to the following steps:

1. Project consultation/quotation of PCB board copying cost

The customer shall provide their own requirements of copying board, introduction of board type, expected time limit of copying board and known information of related PCB board, and negotiate the price of copying board with the service or technical staff of copying board company.

2. The customer provides the mother board and pays the deposit

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

3. The company copies the board according to customer requirements

4. Please confirm the completion of copying board

5. Confirm completion and settle the balance

PCB copying process

PCBS are printed circuit boards without components, and printed circuit boards with components are called PCBA. The following is the PCB board copy process with components.

1. Scan the circuit board picture

Note: Since there may be small patch components under large components, you can scan first and then remove the large ones and scan again.

2. Remove the plate

Remove all the components and remove the tin from the PAD hole. Clean the PCB with board washing water, and then put it into the scanner. When scanning, the scanner selects appropriate pixels according to the fine degree of the board, so as to obtain clearer images. Start OHTOSHOP, sweep the silk screen in color, save the file and print it out for later use.

Note: Pay attention to the polarity and direction of components when removing the plate.

3. Prepare the BOM

According to the circuit board picture in the first step, record the type, parameters and position of all the components on the paper, especially the direction of the diode, the three machine tube and the direction of the IC notch, and finally make the BOM form;

4. Grind the board

Lightly polish the TOP LAYER and BOTTOM LAYER with gauze paper until the copper film shines, then put them in the scanner, start PHOTOSHOP, and sweep the two layers in color separately;

5. Adjust the contrast and brightness of the canvas so that the part with copper film is in strong contrast with the part without copper film, then turn the subdrawing to black and white, check whether the lines are clear, if not, repeat this step. If it is clear, save the picture as black and white BMP format files TOP.BMP and BOT.BMP. If there is any problem with the picture, you can use PHOTOSHOP to repair and correct it.

6. Start the PCB board copying software Protel, import the scanned PCB board pictures in the file menu, convert the two BMP format files into PROTEL format files respectively, and import two layers in PROTEL. If the positions of PAD and VIA after two layers basically coincide, it indicates that the previous steps have been done well.

7. Convert the BMP of the TOP layer to the TOP.PCB, pay attention to the SILK layer, then you trace the line on the TOP layer and place the device according to the drawing of step 2. Delete the SILK layer when you are done.

8. Convert BMP from BOT layer to bot. PCB, same as above to SILK layer, and then you just trace on BOT layer. Delete the SILK layer when you are done.

9. Import TOP.PCB and BOT.PCB in PROTEL, and it is OK to combine them into a figure.

10. Use a laser printer to print the TOP LAYER and BOTTOM LAYER respectively on the transparent film (1:1 ratio), put the film on the PCB, compare if it is wrong, if it is right, a simple double panel will be made!

A dragon PCB copy board service

In the narrow sense, PCB copying only includes circuit board copying, Subroutine Electronics provides a complete package of electronic solution development services such as making BOM list, PCB cloning, chip decryption, material purchasing, prototype production, debugging, maintenance, SMT processing, PCBA processing, one-stop solution to all problems, saving time, financial resources, manpower and other costs for customers.

Transparent PCB copy board price

Subroutine electronic pcb copying board charges using transparent pricing, according to PCB board size, board layer, device density, the difficulty of operation and other related reference factors, developed a detailed calculation of copying board price, do not arbitrarily charge, charge customers a penny more. If customers need other follow-up processing services, the cost of copying board can enjoy a certain discount.
