Car Navigation PCB

A 4-layer car navigation PCB on Rogers RO4350B high-frequency laminate at 2±0.2mm thickness, fabricated with depth-controlled routing to create internal cavities and stepped edges without cutting through the full board. RO4350B provides low and stable dielectric loss across the GNSS, cellular, and Wi-Fi bands used by modern in-vehicle navigation modules, keeping antenna feed lines and RF front-end traces predictable over the automotive temperature range. Depth-controlled routing lets the designer recess connectors, antenna patches, or shielding cans flush with the board and supports complex mechanical fits inside dashboards. Typical applications include GNSS receivers, telematics control units, V2X modules, satellite-based emergency-call (eCall) systems, and combined infotainment-navigation head units for passenger and commercial vehicles.
