DFM DESIGN
Design for Manufacturability (DFM) Review
Identify manufacturing risks early in the design phase, reduce rework, and shorten time to market. The Keep Best DFM team systematically reviews design files from four dimensions: pad design, BOM components, process flow, and test validation.

DFM is not just a design check, but a systematic evaluation of manufacturability before production begins. The review is designed to identify common manufacturing risks early and reduce avoidable rework during pilot or volume production.
Pad Design Issues
Unreasonable pad sizes, insufficient spacing, missing process edges, leading to low placement yield
Identify pad risks early and provide optimization suggestions
BOM Component Risks
EOL components, long lead times, package mismatches affecting material supply
Evaluate component availability and recommend alternatives
Process Flow Barriers
Design structure incompatible with production line processes
Optimize design to adapt to production line processes
Insufficient Test Coverage
Missing test points and interfaces, preventing effective validation
Plan ICT/FCT test point layout
Four-Dimension DFM Review System

DFM Review Process
Submit Files
Gerber, BOM, PCB files, product specification
Initial Assessment
Completeness check and initial risk identification after the submitted files are reviewed
Detailed Review
Systematic review from four dimensions; timing is confirmed after scope and file completeness are assessed
Report Delivery
Complete DFM report with risk list and optimization recommendations
Review Meeting
Communicate results with customer and confirm optimization plan
Iterative Verification
Re-verify after design optimization to ensure risk closure
DFM Review Output
FAQ
Timing is confirmed after the team reviews file completeness, product complexity, test scope and the requested output. The confirmed schedule is communicated for the specific project.
Gerber files, BOM list, PCB design files (.brd or .pcbdoc), and product specification. More complete files lead to more accurate review results.
AI-DFM is an auxiliary tool that quickly identifies common risks; DFM review is a systematic manual review by experienced engineers, more comprehensive and in-depth.
After DFM review, if design files meet manufacturing requirements, you can directly enter RFQ quotation. If optimizations are needed, it is recommended to complete them first.
Yes. Even with incomplete files, Keep Best can conduct preliminary assessment and advise on missing documentation needed.
