What is PCB copy board?

PCB copy board refers to the process of copying the same or similar PCB board as the original board by reverse engineering the existing PCB board. In some cases, copy board is a necessary means, such as the original PCB board has been discontinued or unavailable, but the product needs to be repaired or upgraded. However, copying may also involve intellectual property issues, so it needs to be treated with caution. This article will introduce in detail the definition of PCB copy board, the reasons for copy board, the process of copy board, and the risk of copy board.

一.The definition of PCB copy board

PCB copy board refers to the process of copying the same or similar PCB board as the original board by reverse engineering the existing PCB board. The purpose of copying the board is to obtain the circuit design and layout information of the original PCB board for repair, upgrade or production. The process of copying the board includes dismantling the original PCB board, circuit analysis, drawing schematic diagram, drawing PCB layout diagram, making PCB board and other steps.

二.The reason for PCB copy board

1. The original PCB board has been discontinued or cannot be obtained

In some cases, the original PCB board has been discontinued or unavailable, but the product needs to be repaired or upgraded. At this time, copying the board is a necessary means.

2. The original PCB design is unreasonable or defective

There may be defects or unreasonable parts in the design of the original PCB board, which need to be improved. At this time, the copy board can provide a reference for improvement.

3. The original PCB needs to be mass-produced

The original PCB board needs to be mass-produced, but the original manufacturer cannot meet the demand or the price is too high. At this time, the copy board can provide convenience for production.

三. The process of PCB copy board

1. Disassemble the original PCB board

First of all, the original PCB board needs to be disassembled and decomposed into parts such as circuit boards, components and connecting wires.

2. Circuit analysis

Carry out circuit analysis on the original PCB board to determine the function and connection mode of the circuit.

3. Draw the schematic diagram

According to the circuit analysis results, draw a schematic diagram, determine the connection mode of the circuit and the type of components.

4. Draw the PCB layout

According to the schematic diagram, draw the PCB layout diagram, determine the position of the components and the size of the PCB board.

5. Make PCB board

According to the PCB layout drawing, make the PCB board. The production process includes steps such as making printed circuit boards, drilling, filming, exposure, etching, drilling, and plug-ins.

6. Component installation

Install the components on the PCB board and connect them according to the connection method of the original PCB board.

四. The risk of PCB copy board

PCB copy board involves the issue of intellectual property rights, which may infringe the intellectual property rights of the original manufacturer. Therefore, the following points need to be paid attention to when carrying out PCB copy board:

1. Respect for Intellectual Property Rights

When carrying out PCB copying, it is necessary to respect the intellectual property rights of the original manufacturer and not infringe on its legitimate rights and interests.

2. Compliance with laws and regulations

When carrying out PCB copy board, it is necessary to abide by relevant laws and regulations, and must not violate laws and regulations.

3. Carefully choose copy board manufacturers

When carrying out PCB copy board, it is necessary to choose the copy board manufacturer carefully, and choose a regular and legal copy board manufacturer.

4. Pay attention to confidentiality

When copying PCB boards, it is necessary to pay attention to confidentiality and not to disclose the commercial secrets of the original manufacturer.

In short, PCB copy board is a necessary means, but it needs to be treated with caution. When carrying out PCB copy boards, it is necessary to respect intellectual property rights, abide by laws and regulations, carefully select copy board manufacturers, and pay attention to confidentiality.
