What documents are needed for PCB processing?

PCB processing is an important link in the electronic manufacturing process. Its quality and efficiency directly affect the performance and market competitiveness of the entire electronic product.

In order to ensure the quality and efficiency of PCB processing, a series of necessary documents need to be prepared.

This article will introduce in detail the files required for PCB processing from the aspects of PCB processing process, file types, functions and precautions.

What documents are needed for PCB processing?

PCB processing process

The PCB processing process mainly includes steps such as design, layout, production, testing and assembly. Among them, design, layout and production are the core links of PCB processing, and a series of documents need to be prepared to guide and support the completion of these links. Inspection and assembly require actual operations based on the processed PCB board.

File types required for PCB processing

PCB design files

PCB design files are the basis for PCB processing, including circuit schematics, packaging libraries, PCB layout diagrams, network tables, BOM tables, etc.

Among them, the circuit schematic diagram is the starting point of design, the packaging library refers to the packaging information of components such as chips and devices, the PCB layout diagram refers to the layout information of each component on the PCB board in the schematic diagram, and the network table refers to the layout information on the PCB board. The connection information between various components, the BOM table refers to the list of components used on the PCB board.

PCB production files

PCB production files are important files for PCB processing, including Gerber files, drilling files, patch files, etc. Among them, the Gerber file is a key file for PCB board production. It contains information such as lines and hole positions of each layer of the PCB board. The drilling file refers to the various hole position information on the PCB board. The patch file refers to the patch process. Required documents.

PCB inspection file

PCB inspection files are important documents for PCB processing, including AOI inspection files, X-ray inspection files, ICT inspection files, etc. Among them, the AOI inspection file refers to the automatic optical inspection file, which is used to detect whether the circuits and components on the surface of the PCB board meet the requirements.

The X-ray inspection file refers to the welding quality and component connection condition inside the PCB board. ICT detection files are used to detect the connections of circuits and components on the PCB board.

The role of PCB processing files

Guide the production process

PCB processing files are important guidance documents for making PCB boards. Through these files, PCB boards that meet the requirements can be accurately produced.

Ensure product quality

PCB processing documents can ensure the quality of the PCB board. Through these documents, we can accurately detect whether the lines, hole positions, welding quality, etc. on the PCB board meet the requirements, thereby ensuring the quality and reliability of the product.

Increase productivity

PCB processing files can improve production efficiency. These files can accurately guide the production process and processing procedures, thereby reducing errors and duplication of work during the production process, and improving production efficiency and processing accuracy.

Things to note when processing PCB files

Accuracy of documentation

PCB processing files need to be accurate, any error may lead to processing failure. Therefore, special attention should be paid to details and accuracy when making PCB processing files to ensure that the location, size, connection and other information of each component are accurate.

Standardization of documents

PCB processing files need to comply with relevant standards and specifications to ensure that the processed PCB board is consistent with the design and meets relevant quality requirements. Therefore, relevant standards and specifications must be followed when producing PCB processing files to ensure standardization and standardization of files.

File security

PCB processing documents are one of the company’s core secrets and need to be kept strictly confidential. Therefore, when making PCB processing files, pay attention to the security of the files to ensure that the files will not be leaked or damaged.

To sum up, the files required for PCB processing include PCB design files, PCB production files, PCB inspection files, etc. These files can guide the production process, ensure product quality, and improve production efficiency. When producing these documents, attention needs to be paid to issues such as document accuracy, standardization, and security to ensure successful processing and stable product quality.
