Design for Manufacturability (DFM) Support
Our DFM support focuses on machining feasibility and practical optimization for RF modules.
We analyze design details from a manufacturing perspective—including waveguide geometry, split-block structures, wall thickness, tolerances, and assembly interfaces—to ensure the design can be machined reliably and repeatedly.
Based on this analysis, we provide engineering-level suggestions on how to adjust structures to:
Improve RF performance by maintaining stable waveguide paths and alignment accuracy;
Enhance mechanical strength and long-term stability;
Reduce machining complexity and overall production cost.
By aligning design intent with real machining constraints, we help bridge the gap between prototype and scalable production, enabling smoother transition from one-off samples to stable batch manufacturing.
Confidentiality Assurance
All DFM reviews and technical discussions are handled under strict confidentiality.
Customer drawings, design details, and any optimization suggestions are used solely for feasibility analysis and manufacturing evaluation, and are never shared with third parties or reused for other projects.
Confidentiality is treated as a fundamental requirement, not a formality.
