What it is

High power LED PCBs designed around heat

Once an LED draws a watt or more, the board stops being a passive carrier and becomes part of the cooling system. A high power LED PCB is built to move heat from the junction to the heatsink as efficiently as possible, because junction temperature decides both brightness and lifespan.

The thermal path runs through the dielectric, the base metal and the interface to the heatsink. The dielectric is usually the biggest controllable bottleneck, so we select high thermal-conductivity laminates on aluminum or copper-core bases, and step up to a ceramic LED PCB when even that is not enough. Heavy copper and thermal vias complete the design.

How it works

Engineering the thermal path

A high-power board is a stack of thermal resistances in series. We minimise each: a high-conductivity dielectric, a metal or ceramic base, heavy copper to spread current, and filled thermal vias to carry heat vertically to the heatsink.

  • High-TC dielectric — the biggest controllable resistance.
  • Metal / ceramic base — matched to your power level.
  • Heavy copper — up to 6 oz for spreading.
  • Thermal vias — vertical path to the heatsink.
  • DFM modelling — against your diode and current.

Answers

High power LED PCB — FAQ

A short, low-resistance thermal path from the diode junction to the heatsink — a high thermal-conductivity dielectric on a metal-core or ceramic base, plus heavy copper and thermal vias.

Aluminum with a high-TC dielectric handles most designs up to roughly tens of watts. For 50 W and above or dense COB engines, an aluminum nitride ceramic base conducts heat directly and is usually required.

We offer heavy and extreme copper up to 6 oz for current spreading and additional heat distribution on high-power boards.

Yes — filled and plated thermal vias create vertical heat paths that lower thermal resistance, especially under high-power emitters and COB packages.

Yes — turnkey fabrication, high-power diode sourcing, assembly and testing. See LED PCB assembly.
