Precision Redefined: 0.79mm Blind Via-in-Pad Rogers PCBs with ±1.5% Impedance Control for 40GHz Systems
The Millimeter-Wave Manufacturing Challenge
In 5G mMIMO, satellite comms, and defense radar systems, blind vias in pads enable 70% space savings versus traditional dog-bone routing. Yet achieving this in Rogers laminates while maintaining:
±1.5% impedance tolerance at 40GHz
Phase coherence <0.5° across antenna arrays
Thermal reliability through 5× lead-free reflows
...demands nano-scale precision few fabs master.
Our Solution: China's most advanced Rogers PCB prototype line delivers:
✅ 0.79mm laser-drilled blind vias (aspect ratio 1:1.5)
✅ ±0.025mm hole position tolerance
✅ TDR-validated impedance control to 110GHz
✅ Zero pad cratering at -55°C↔+150°C thermal cycles
