Why Choose Us?

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

Thermal conductivity 175–385 W/m·k — Direct to copper reaches up to 385 W/m·k versus only 1.0 W/m·k for a regular MCPCB.

Lower LED junction temperature — Heat leaves the LED pad directly into copper, 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 direct thermal path without redesigning the board.

Frequently Asked Questions

1. What is a 2-layer DTP copper core PCB?

It is a two-layer Direct Thermal Path board built on a copper substrate: the LED’s thermal pad bonds straight to the copper with no dielectric in the heat path, giving direct-to-copper conductivity up to 385 W/m·k while the second layer adds routing area.

2. When should I choose 2-layer instead of 1-layer DTP?

The source page notes that when a design has many components and no space to lay them out on a single layer, a 2-layer direct thermal path copper core PCB is required. The second layer gives the extra routing space while keeping the direct copper thermal path.

3. What thermal conductivity can I expect?

Direct to copper, DTP reaches up to 385 W/m·k (and 175 W/m·k direct to aluminum), versus only 1.0 W/m·k for a regular MCPCB — a drastic drop in thermal resistance.

4. 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.
