What are the data parameters that need to be prepared to customize PCB?

Hits : 2

When customizing PCB, some important parameters in the information that need to be prepared include:

Schematic: The final version of the schematic for the project design, including all paginated schematics.

Package Library: PCB package library or component Datasheet file used to create a new package library.

Structural Diagram: A DXF structure file containing the placement of main connectors and height limits.

Design Description: Including key signal processing, special design requirements for the chip, and board manufacturing process instructions.

Important Device Data Sheets: Recommended layout and wiring for reference during design.

Stacking Settings: Based on the flying lines after PCB layout, estimate the number of PCB layers required for the design, and calculate the line width and line spacing based on the number of layers and board thickness.

Rule Setting: Set line width and line spacing rules on the PCB, and check the design requirements and the process requirements of the board factory.

Class Setting: According to IC signal requirements, group signals with design requirements, set them into different Classes, and set corresponding Class rules.


Import of Netlist: Ensure that the schematic network connection and device packaging are imported into the PCB without deviation.

Import of Structure: Import board frame, device positioning information and other contents into PCB.

Drilling Compensation: Set the compensation parameters of via holes and component holes according to the type of board (such as spray tin board, immersion gold board, nickel gold board, etc.).

Line Width Compensation: Set the line width compensation parameters according to the thickness of the copper foil.

Spacing: Distance from line to line, distance from line to disk, distance from disk to disk, etc.

Overall Dimensions: V-CUT copper extraction size depends on the board thickness.

Welding Mask Production: Wet green oil window opening, cover line, IC position green oil bridge and other parameters.

Text Production: Line width, distance when the text cover is soldered, etc.

Typesetting Spacing: CNC spacing, die punching spacing.

Knife and Drill Size: Minimum Knife and Drill Size, and Maximum Drill Size.

Electrical Performance Requirements: Including signal integrity, power supply stability, electromagnetic compatibility, etc.

Thermal Management: Thermal design is crucial to ensure the long-term stable operation of the PCB, and the heat dissipation path, layout and component selection need to be considered.

Component Selection: Including component type, specification, packaging form, and supplier reliability.

Mechanical Stability: The mechanical design of PCB needs to ensure physical stability in various usage environments.

Cost Budget:Cost factors need to be considered when customizing PCBs, including materials, manufacturing processes, and testing.


Environmental Protection Requirements: Certain industries or regions may have specific environmental protection requirements that require the use of specific materials or processes.

Testing and Verification: The design phase should consider how the PCB will be tested and verified to ensure it meets the design specifications.

Assembly Process: Including the applicability of SMT (Surface Mount Technology) and THT (Through Hole Technology).

Long-term Reliability: The reliability of PCB in long-term use needs to be considered, such as temperature resistance, moisture resistance, etc.

Version Control: Ensure that versions of design files are properly managed so changes can be tracked and maintained.

File Formats and Data Exchange: Prepare file formats for exchange with PCB manufacturers, such as Gerber files, IPC netlists, etc.

Design Review: A thorough review after the design is completed to identify and correct possible problems.

Supply Chain Management: Ensure a stable supply chain for all components and materials to avoid production delays.

Customer-specific Requirements: Some customers may have specific design and manufacturing requirements that need to be taken into account during the design phase.

Regulatory Compliance: Ensure PCB design complies with relevant industry standards and regulatory requirements.

These factors will affect the final performance and quality of the PCB, so they need to be considered comprehensively during the process of customizing the PCB.
