3 .PCB Design Process: From Concept to Production
Design Preparation and Planning: PCB design is a systematic process that begins with defining the product’s electrical functionality and mechanical constraints. Electronic design automation (EDA) tools like Altium Designer (AD) provide comprehensive PCB design solutions, from schematic drawing and PCB layout to final manufacturing file output.
Before beginning design, you need to determine the number of PCB layers, dimensions, materials, and key components. This stage is particularly important for custom PCBs, as it determines the feasibility and cost of subsequent manufacturing.
Schematic Design: The schematic is the blueprint for the PCB design, using symbols to represent electronic components and lines to illustrate the electrical connections between them. In Altium Designer, you can use existing component libraries or create custom components.
For complex designs, a hierarchical schematic can be used to divide the entire system into multiple functional modules, making the design more modular and manageable.
PCB Layout and Routing: Once the schematic is complete and passes electrical rule checking (ERC), the next step is to convert it into a physical PCB layout. This process includes:
Defining the Board Outline: Draw the board outline on a mechanical layer or a keep-out layer.
Component Placement: Optimize component positions to reduce trace lengths and improve signal integrity.
Routing: Connect all components while adhering to design rules (such as line width and spacing).
Design Verification and Output: After routing is complete, design rule checking (DRC) and signal integrity analysis are performed to ensure the design meets all requirements. Manufacturing files (such as Gerber files, drill files, and mounting files) are then generated and sent to the PCB manufacturer for production.

5. How to Select Custom PCB Services: Considerations and Best Practices
Technical Capabilities Assessment: When selecting a custom PCB service provider, consider the following technical factors:
Laminate Material Selection: Does the supplier offer material options suitable for your application?
Advanced Process Support: Does the supplier support specialized processes such as HDI, microvias, and thick copper?
Manufacturing Precision: What are the process capabilities for minimum line width/line spacing, minimum aperture, etc.?
Quality Control: What testing equipment and quality assurance processes does the supplier have?
Business Considerations: In addition to technical capabilities, the following business factors should be considered:
Prototype and Mass Production Capabilities: Does the supplier have the capability to support prototypes all the way through mass production?
Delivery Time: Can your project timeline be met?
Cost Structure: Is the pricing transparent, and are there any hidden costs?
Customer Support: Is design support and technical consulting provided?
Design Preparation Tips: To ensure a smooth PCB customization project, please follow these best practices:
Provide complete design documentation: This includes Gerber files, drill diagrams, bill of materials (BOM), and assembly drawings.
Clarify Special Requirements: Communicate requirements for impedance control, surface finish, special testing, etc. in advance.
Conduct a Design for Manufacturability (DFM) review with the manufacturer before committing to manufacturing.
Consider Design for Manufacturability (DFM): Follow DFM principles to avoid designs that are difficult or costly to manufacture.
