Copper traces are conductive pathways etched onto PCB substrates to electrically connect components.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Spacing | ≥0.1 mm (standard), down to 0.05 mm (high-density) | |
| Width Range | 0.1 mm to 10 mm | |
| Conductivity | ≥58 MS/m (pure copper) | |
| Adhesion Strength | ≥1.0 N/mm (to substrate) | |
| Surface Roughness | ≤2 μm (for signal integrity) | |
| Typical Thickness | 17.5 μm to 70 μm |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

A printed circuit board that provides electrical connections and mechanical support for electronic components in a camera module.
A specialized printed circuit board (PCB) designed to implement filtering functions within an EMI Filter Panel.
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 Copper Traces.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Trace width is determined by current-carrying capacity (to prevent overheating), impedance requirements (for high-speed signals), manufacturing capabilities (minimum feature size), and voltage isolation (spacing to prevent arcing).
Traces are protected by surface finishes like ENIG, HASL, or OSP, which provide a solderable, non-oxidizing layer. In some cases, a solder mask (polymer coating) covers non-solderable areas.
