PCB copying technology: precise copying and efficient remanufacturing

In the field of modern electronics manufacturing, PCB (printed circuit board) is the core carrier of electronic products. In some cases, due to the loss of original design documents, product upgrades or maintenance needs, PCB copying (that is, reverse engineering and copying of existing boards) has become a key technology. This paper will analyze the concept, core process and key technologies of PCB copying board, and introduce our professional ability and successful experience in the field of PCB copying board.

First, the concept and significance of PCB copying board

PCB copying technology mainly refers to the reverse engineering of the physical structure and wiring path of the existing circuit board, re-generating the circuit design file, and copying the new circuit board. Its main significance is:

Restore the original design: When the original design data is lost or incomplete, the product layout can be quickly restored through copying technology.

Product maintenance and upgrade: For the maintenance, improvement and upgrade of old products, the copying board can effectively copy the circuit structure to ensure compatibility and stable performance.

Imitation and R&D: In the process of developing new products, we obtain experience and data through copying the existing successful products, and promote technological innovation and optimization.

Second, the key technology and process of PCB copying board

PCB copying is a composite process that integrates a variety of detection, analysis and mapping technologies. The main processes include:

Disassemble and photograph the circuit board

First of all, the PCB of the copying board is disassembled, and the detailed layout of each layer of the board is recorded by high-definition photography and scanning technology. Some companies will also use advanced equipment such as X-ray detection to obtain information about the internal structure of the hidden layer.

Image processing and data extraction

Professional software is used to analyze and process the captured images, extract the data of component position, routing, hole position, etc., and reconstruct the preliminary circuit diagram. In this process, key factors such as signal integrity, interlayer connection and heat dissipation layout need to be taken into account.

Design document reconstruction

Based on the extracted data, the original design document is reconstructed through EDA (Electronic Design Automation) software. At this stage, engineers will make the necessary optimizations and corrections to ensure that the copied circuit diagram is highly consistent with the original board.

Prototype production and verification

After the completion of the design document, the prototype will be produced on a trial basis. After multiple rounds of testing and verification (including electrical performance, signal integrity, durability and other tests), it is confirmed that the various indicators of the composite meet the requirements, and then enter the mass production process.
