Brief: Discover the advanced OEM 4mil 4835 Rogers Board PCB Fabrication, designed for high-frequency 50 ohm applications. This 6-layer PCB features Rogers 4835 LoPro material, ENIG surface finish, and is ideal for 77GHz millimeter wave radar systems in autonomous driving. Learn how its ultra-stable Dk and near-zero loss ensure superior signal integrity and reliability.
Related Product Features:
  • Material: Rogers 4835 LoPro 4mil for high-frequency performance.
  • 6-layer design with red color and 1OZ copper for durability.
  • ENIG surface finish prevents oxidation and minimizes skin effect losses.
  • Ultra-stable Dk: 3.48 @ 10GHz (±0.05 tolerance) for minimal phase drift.
  • Near-zero loss: Dissipation factor (Df) of 0.0037 for reduced signal attenuation.
  • Thermal resilience: CTE matched to copper for reliability under extreme temperatures.
  • Moisture resistance: <0.02% water absorption for automotive-grade reliability.
  • Lead-free assembly compatibility: Survives 3x reflow cycles at 260°C.
Faqs:
  • What makes Rogers 4835 material ideal for 77GHz radar systems?
    Rogers 4835 offers ultra-stable Dk, near-zero loss, and thermal resilience, ensuring signal integrity and reliability at high frequencies.
  • How does the hybrid stackup design reduce costs?
    The hybrid stackup uses RO4835 for critical layers and FR-4 for others, slashing material costs by 25% while maintaining performance.
  • What certifications are required for automotive-grade PCBs?
    Automotive-grade PCBs require IATF 16949, IPC-6012 Class 3, and PPAP documentation support for reliability and performance validation.
