1. Design File Review

• File Integrity Check: Ensure all necessary files (such as Gerber files, Bill of Materials (BOM), assembly drawings, etc.) are provided and complete.
• Format Compatibility Check: Verify that the file format is compatible with production equipment to avoid production errors due to format issues.
• Design Rule Check (DRC): Use professional software to check if the design complies with DFM rules, such as line width, spacing, aperture, and more.

2. Design for Manufacturability (DFM) Analysis

DFM analysis is the core step in identifying and resolving potential issues in design files. This includes:

• PCB Layers and Thickness: Verify that the design matches the layer count and thickness limitations of the production equipment.
• Component Layout: Ensure the component layout is reasonable, avoiding difficult-to-solder areas or poor heat dissipation.Pad 
• and Via Design: Check if the pad and via sizes meet the requirements of the production process.Signal Integrity: Analyze the 
• design of high-speed signal lines to avoid signal interference or attenuation.

3. Component Selection and Substitution

• Component Availability Check: Confirm that the components in the BOM are readily available in the market.
• Alternative Solutions: Provide customers with alternative components that have similar performance and are easier to procure.
• Lifecycle Management: Avoid selecting components that are nearing end-of-life to ensure the long-term maintainability of the product.

4. Communication and Feedback with Customers

• Problem Report: Compile the identified issues into a detailed report with improvement suggestions.
• Technical Discussion: Engage in in-depth discussions with the customer's technical team to explain the severity of the issues and the necessity for improvement.
• Design Modification Confirmation: After the customer modifies the design, re-review the files to ensure the issues have been resolved.

5. Final Verification Before Production

• Prototype Production and Testing: Produce a small number of prototypes and conduct functional testing to ensure the design meets expectations.
• Small Batch Trial Production: Verify the feasibility and stability of the production process through small batch trial production.
