In today’s rapidly developing technological era, electronic products have become an indispensable part of people’s lives. As an important component of electronic products, the quality of PCB circuit boards directly affects the performance and stability of electronic products. Therefore, choosing a professional PCB processing factory for processing and sampling is particularly important. So, what information do we need to provide before processing and sampling PCB circuit boards?
一、Structural diagram of PCB circuit board
Gerber file: Gerber files are the original files used for PCB board manufacturing, containing all the graphic and dimensional information of the PCB board. When providing Gerber files, it is necessary to ensure that the file format is correct and includes all layers (including top layer, bottom layer, silk screen layer, etc.).
Drilling file: Drilling files are used to indicate the location and aperture size of holes that need to be drilled on PCB circuit boards. Usually, the format of drilling files is Excellon format.
IPC document: IPC document is an industry standard document for PCB circuit board manufacturing, which includes manufacturing requirements, quality standards, and other information for PCB circuit boards. When providing Gerber files, it is necessary to ensure that the files comply with IPC standards.
二、 Relevant parameters of PCB circuit board
Board layer structure: including the number of layers, copper foil thickness, dielectric layer thickness, and other information of the PCB circuit board.
Aperture size and hole position accuracy: It is necessary to determine the aperture size and hole position accuracy on the PCB circuit board to ensure the quality and reliability of the circuit board.
Surface treatment methods: including the surface treatment methods (such as tin spraying, gold plating, immersion gold, etc.) and thickness requirements for PCB circuit boards.
The size and accuracy of circuits and pads: It is necessary to determine the size and accuracy requirements of circuits and pads on the PCB circuit board to ensure the performance and reliability of the circuit board.
Special process requirements: If the PCB circuit board requires special process requirements, such as blind buried holes, metalized holes, etc., they need to be explained to the processing factory before processing and sampling.
三、 Requirements for PCB board layout
Layout method: It is necessary to determine the layout method of the PCB circuit board to improve production efficiency and reduce costs.
Splicing quantity: It is necessary to determine the number of PCB boards to be spliced to meet production requirements.
Positioning holes and reference points: It is necessary to set positioning holes and reference points on the PCB circuit board for positioning and calibration during the production process.
四、Other requirements for PCB circuit boards
Special material requirements: If the PCB circuit board requires the use of special materials such as Rogers circuit boards, high-frequency circuit boards, etc., it is necessary to explain to the processing factory before processing and sampling.
Production cycle and delivery requirements: It is necessary to explain the production cycle and delivery requirements of PCB circuit boards to the processing plant, so that the processing plant can arrange the production plan reasonably.
Other requirements: If there are other special requirements for the PCB circuit board, such as environmental protection requirements, certification requirements, etc., they need to be explained to the processing factory before processing and sampling.
In short, before conducting PCB circuit board processing and sampling, detailed information and requirements need to be provided to the processing factory to ensure the smooth progress of processing and sampling and meet your needs. At the same time, choosing a professional PCB processing factory is also very important, as they will provide you with high-quality services and high-quality PCB circuit boards.
