Single-layer MCPCB
Single-layer metal-core PCB for LEDs
Single-layer MCPCB with one trace layer on an aluminum or copper core, for LED and power thermal paths. Dielectric conductivity is about 0.8–3.0 W/m·K depending on stack-up.
Published specification
| Parameter | Published value |
|---|---|
| Construction | Single layer: one trace layer on a metal core |
| Core metal | Aluminum or copper |
| Dielectric thermal conductivity | About 0.8–3.0 W/m·K, stack-up dependent |
| Aluminum conductivity | About 237 W/m·K for the metal |
| Copper conductivity | Up to about 398 W/m·K for the metal |
| Dimensional stability | About 2.5–3.0% size change from 30 °C to 140–150 °C, typical |
| Primary benefit | Heat removal from LEDs and power devices through the metal base |
Where this applies
LED lighting and other heat sources that need one trace layer on a metal base.
This page is the published single-layer construction: one trace layer on the metal core. Conductivity figures are the hub envelope for the metal and the dielectric, not a measured value for a specific stack-up. The fab grid is confirmed from the thermal brief and Gerbers.
Questions
How many trace layers does this construction have?
One. The hub describes single-layer MCPCB as one trace layer on a metal core.
Are the conductivity numbers a guaranteed stack-up?
No. Dielectric conductivity is about 0.8–3.0 W/m·K and depends on the stack-up. Aluminum and copper figures are for the metal itself.
