Ground planes are conductive layers in PCBs that provide electrical reference points, reduce noise, and enhance signal integrity in electronic circuits.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Thickness | 0.035 mm to 0.070 mm | |
| Conductivity | ≥ 5.8×10⁷ S/m | |
| Surface Roughness | < 1.2 μm | |
| Dielectric Constant | Dependent on substrate (e.g., FR-4: 4.2-4.5) | |
| Thermal Conductivity | 385 W/(m·K) |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Ground Planes.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Ground planes provide a low-inductance return path, control impedance, and minimize signal reflections, which is critical for maintaining signal integrity at high frequencies.
Yes, but carefully. Split ground planes can isolate noisy circuits but may create ground loops or impedance issues if not designed properly, often requiring stitching vias or careful routing.
