What is SinkPad PCB?

SinkPAD PCB is a special type of metal core PCB( MCPCB ),
The LED sink heat pad solder direct to the metal substrate,
Also,it is called Thermal pad MCPCB,direct thermal path mcpcb.

LEDs Chip Thermal Pads solder direct to the Aluminum or Copper substrate directly,
No dielectric between LEDs heat out pads and the Metal core.
Means,thermal resistance is very small and ,
Thermal conductivity could be 235 W/m.k to 400 W/m.k.

There are 2 types metal substrate,
Aluminum core sinkpad PCB and copper core sinkpad PCB.

Aluminum core sinkpad PCB thermal conductivity could be 235 W/m.k,
Copper core sinkpad PCB thermal conductivity could be 400 W/m.k

Copper substrate sinkpad PCB stack up

Metal core PCB’s thermal conductivity only 1.0 W/m.k, maximum 12 W/m.k.

Sinkpad PCB thermal conductivity is much better than metal core PCB.

The SinkPad PCB provides fine heat transfer from the LED to the metal substrate,

Thermal conductivity of 2 Layers thermal Pad MPCB

Thermal pad area is 385 W/m.k

2 Layers direct thermal path copper core pcb application

2 Layers direct thermal path copper core pcb are designed to dissipate heat generated by high-power LEDs,
which helps to increase the lifespan of the LED and improve its performance.
The aluminium base acts as a heat sink, which absorbs and dissipates the heat generated by the LED.

The 2 Layers direct thermal path copper core pcb is made by laminating a thin layer of copper onto an copper substrate.
The copper layer is then etched to create the circuit pattern.
2 Layers direct thermal path copper core pcb for LED lighting applications are available in various sizes and thicknesses, depending on the specific requirements of the application.
They are also available in single-sided, double-sided, and multi-layered configurations.
