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%)
  • Fig.3: Real-time production monitoring dashboard

4. Production Results & Customer Value

A. Key Delivery Metrics

Parameter Requirement KKPCB Result Industry Benchmark
Amplitude Consistency ±0.5dB ±0.45dB ±1.0dB
Phase Stability ±1° ±0.8° ±2°
Yield Rate ≥95% 98.2% 90-92%
Lead Time 8 weeks 7 weeks 12 weeks

B. Manufacturing Value Proposition

✓ Process Expertise:

  • Mass production of PTFE boards with copper paste vias (6% higher yield than industry)
  • Proprietary HDI lamination compensation database (500+ parameter sets)
    ✓ Cost Efficiency:
  • 15% cost reduction per board through materials recycling and parameter optimization
    ✓ Responsiveness:
  • 72-hour prototype turnaround (industry standard: 1 week)
