PCB copy board services

Since its establishment 15 years ago, ShenZhen OROD has specialised in
PCB copy business. As the company’s scale continues to grow and develop, it is in the leading position in the industry in PCB copy board, chip decryption, circuit diagram revision, BOM parameter test, reverse push schematic, prototype debugging production, and PCB finished product mass production. OROD can submit more than 20 successful cases every day.

SZOROD company combines new EDA design software, professional copy PCB technicians, and advanced process technology. It can clone single-layer, double-layer, and multilayer (up to 32 layers) PCB circuit boards. It is a highly demanding PCB circuit board for copying work, whether it is dense components, spread over microstrip lines, isometric computer motherboards, high-end graphics boards, Gigabit network equipment substrates. Or strict requirements for high-frequency processing, strict electromagnetic compatibility control For PHS motherboards, mobile phone motherboards, wireless network cards, and other wireless communication equipment. And blind and buried industrial control motherboards, we can all successfully clone them in one time based on a set of intact templates (or prototypes) provided by customers, and promise to cooperate with the original PCB. The circuit is 100% identical.
During the board copying process, our professional board modification team can also provide you with PCB board modification services. According to the individual needs of customers, we can change the position of components in the board and re-layout the wiring to achieve the desired results.

1, Get a PCB, first record the model, parameters, and location of all components on the paper, especially the direction of the diode, the triode, and the direction of the IC gap. It is best to use a digital camera to take two photos of component locations. The more advanced the pcb circuit board is, the more inadequate the diode transistor can’t be seen at all.


2, Remove all devices and remove the tin in the PAD hole. Clean the PCB with alcohol, and then put it into the scanner. When the scanner scans, it needs to adjust the scanned pixels slightly to get a clearer image. Then lightly polish the top and bottom layers with gauze paper until the copper film is shiny, put it into the scanner, start PHOTOSHOP, and scan the two layers separately in color. Note that the PCB must be placed horizontally and vertically in the scanner, otherwise the scanned image cannot be used.
3,Djust the contrast, brightness and darkness of the canvas to make the part with copper film and the part without copper film have strong contrast, and then turn the sub-picture to black and white to check whether the line is clear. If it is not clear, repeat this step. If it is clear, save the picture as black and white BMP format files TOP.BMP and BOT.BMP, if you find a problem with the picture, you can use PHOTOSHOP to repair and correct it.
4,Convert the two BMP format files into PROTEL format files, and transfer two layers in PROTEL. For example, the positions of PAD and VIA in the two layers basically coincide, indicating that the previous steps have been done well. If there is a deviation, repeat the third step. So PCB copying is a very patient job, because a small problem will affect the quality and the degree of matching after copying.

The fifth step is to convert the BMP of the TOP layer to TOP.PCB, pay attention to the SILK layer, which is the yellow layer, then you can trace the line on the TOP layer, and place the device according to the drawing of the second step. Delete the SILK layer after painting. Repeat until all layers are drawn.
The sixth step is to transfer TOP.PCB and BOT.PCB in PROTEL and combine them into one picture.
The seventh step is to use a laser printer to print the TOP LAYER and BOTTOM LAYER on transparent film (1:1 ratio), put the film on that PCB, and compare whether it is wrong. If yes, you are done. .
A copy board that was the same as the original board was born, but it was only half finished. There is also a test to test whether the electronic technical performance of the copy board is the same as the original board. If it is the same then it is really done.
