SSS:

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.
