Direct Thermal Path MCPCB

Andwin Circuits manufactures Direct Thermal Path (DTP) MCPCB where high-power LED thermal pads bond straight to the aluminum or copper substrate — no dielectric layer in the heat path, delivering 175–385 W/m·k thermal conductivity.

Types of Copper Core PCB

The main copper-core constructions we build for customers — from standard stack-ups to embedded and hybrid laminates.

DTP MCPCB Stack-up

LED thermal pad soldered straight to the aluminum / copper substrate; dielectric removed from the heat path.

2 Layers DTP MCPCB

Two-layer direct thermal path board with the LED mounted on the exposed metal core.

2-Layer DTP Copper Core

Copper-core variant reaching up to 385 W/m·k direct thermal conductivity.

DTP Copper Core w/ Isolated Holes

Copper-core DTP board with electrically isolated through holes for signal routing.

Why Choose Us?

No design change required — DTP keeps your existing LED layout; the thermal pad simply bonds to the exposed metal core.

Thermal conductivity 175–385 W/m·k — Versus only 1.0 W/m·k for a regular MCPCB, drastically lowering thermal resistance.

Lower LED junction temperature — Heat leaves the LED pad directly, keeping the junction cooler under high power.

Longer LED life — Lower operating temperature extends the service life of power LEDs.

Most economical DTP solution — A cost-effective way to get a direct thermal path without redesigning the board.

Frequently Asked Questions

1. What is a Direct Thermal Path (DTP) MCPCB?

A DTP MCPCB bonds the LED’s thermal pad straight to the aluminum or copper substrate with no dielectric layer in the heat path, so thermal resistance is extremely low — conductivity reaches 175 W/m·k to aluminum and up to 385 W/m·k to copper, versus only 1.0 W/m·k for a regular MCPCB.

2. How is DTP different from a regular MCPCB?

A regular MCPCB has a dielectric insulation layer between the circuit and the metal core that blocks most heat. In a DTP board the dielectric is removed under the LED thermal pad, letting heat go straight into the metal — far better cooling with no board redesign.

3. Which LEDs can use DTP MCPCB?

The source page lists Cree XP-G/E/C/G2, XM-L/XM-L2, MT-G/MT-G2, MK-R, XT-E, XB-D, XHP70 N4, Bridgelux SM4, Luxeon Rebel/M/T, LEDEngin LZC/LZP, Nichia N219A/N219B, Seoul Z5P/Z5M, Osram Oslon SSL, Samsung 3535 and LG Innotek 3535.

4. Does DTP require changing my LED layout?

No — one of the stated advantages is that no design change is required. The existing LED footprint works; only the substrate construction changes to expose the metal core under the thermal pad.
