Custom multilayer PCB windings for planar transformers and inductors — precision-etched copper traces that replace wire windings, engineered for low profile, low leakage inductance and high repeatability.
| Parameter | Range / option |
|---|---|
| Layer count | 2 – 20 layers |
| Copper weight | 1 oz (35 µm) · 2 oz (70 µm) · 3 oz (105 µm) · 4 oz (140 µm) · 5 oz (175 µm) |
| Base material | FR4 · FR5 · Polyimide |
| Surface finish | ENIG · OSP · immersion tin · lead-free HASL |
| Winding design | Custom layout · interleaved windings · isolation barriers · multi-turn / layer |
Three base materials to match your thermal and cost targets — standard FR4, high-temperature FR5, and polyimide for the most demanding thermal environments. FR5 resists delamination and warpage during reflow and heavy-copper processing.
Send your schematic, footprint and power target — our engineers will lay out the winding and pair it with the right core.
