Contact: [email protected]
1. Project Background
Industry: Satellite Communications/Military Radar
Application Scenario:
- 256-channel phased array antenna system (28GHz Ka-band)
- Customer requirements: ±60° beam steering, ±0.5dB amplitude consistency, 8-week delivery
2. Customer Pain Points & Manufacturing Challenges
| Challenge Category | Original Design Issues | KKPCB Manufacturing Solutions |
|---|---|---|
| Process Compatibility | Customer’s 20-layer HDI design lacked mass production feasibility | Optimized materials and processing parameters for seamless design-to-manufacturing transition |
| Consistency Control | ±0.5dB amplitude tolerance beyond conventional process capabilities | Developed proprietary process control protocols |
| Lead Time | Industry standard 12 weeks vs. customer’s 8-week demand | Streamlined production workflow by eliminating non-critical steps |
3. KKPCB’s Core Manufacturing Optimizations
A. Precision Lamination & Drilling Control
- Innovations:
- Laser drilling with pre-compensation: Achieves ±7.2μm alignment accuracy (industry average: ±15μm)
- Step-wise lamination parameters: Reduces PTFE interlayer voids (delamination rate: 0.3% vs. 5% industry standard)
- Fig.1: Cross-section micrograph (demonstrating void-free layer structure)
B. Copper Paste Via-Filling Breakthrough
- Mass Production Enhancements:
- Custom vacuum filling equipment: Ensures ±2μm via-wall copper uniformity (vs. ±5μm with electroplating)
- Low-temperature curing formula: Prevents PTFE substrate deformation (phase stability: ±0.8°@28GHz)
- Fig.2: SEM micrograph of copper paste vias (showing wall uniformity)
C. Smart Manufacturing & Process Reengineering
- Efficiency Gains:
- Modular production: Parallel processing of 20-layer boards as 4 modules reduces cycle time by 35%
- AI visual inspection: Real-time monitoring of critical parameters (line width/aperture), lowering defect rate to 0.5% (from 3%)
