MCPCB-XEG-Q20-CU

Description

MCPCB-XEG-Q20-CU. This printed circuit board with Copper base has been developed for Cree XEG and allows you to quickly create your prototypes of LED modules based on Cree XEG Leds. With it’s high thermal conductivity of 390 W/mK with its direct thermal path, this printed circuit board is able to drain the heat of the LED components through the Copper base, which is ideal for LED lighting. This Metal Core PCB is manufactured with UL certified Copper substrates.

The MCPCB-XEG-Q20-CU is designed to take three Cree XEG Led. The board layout is for 4 leds in either addressable or series configuration and can be load with resistors for current limiting on board for CV operation.

Thermal Path :  No dielectric under the thermal pad of LED

The module requires careful attention to mounting and cooling to ensure that the junction temperature of the LED is kept well below the maximum rating as specified in the LED documentation published by Led Manufacturers

For optimal cooling, we recommend that the module be mounted to a suitable finned heat sink (aluminium or copper) that is exposed to open air. The module can be mounted to a heat sink in various ways

• 20mm pressure sensitive, thermally conductive tape (Recommended)
• Thermal Compound: Requires the use of mechanical fasteners

Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximise heat transfer to the the sink.

The bottom of the LED MCPCB is electrically neutral, so it is not necessary to electrically isolate the base from the cooling surface.
