MCPCB-MCERGBW-35T

MCPCB-MCERGBW-35T: This Aluminium PCB is very specifically Cree MCE RGBW. It is designed to take 1 leds, with 5.0 × 5.0mm base, so will suit Cree MCE RGBW,  and other multi die leds with the same base dimensions.

*Please check manufacturers data sheets to ensure compatibility with this PCB foot print

Non Direct Thermal Path : Dielectric under the thermal pad of LED

The MCPCB-MCERGBW-35T Linear board 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 heat sink (aluminium Flat plate is perfect but total thickness will depend on the total power used) that is exposed to open air. The module can be mounted to a heat sink in various ways

• Pressure sensitive, thermally conductive tape (Recommended)
• Arctic Alumina thermally conductive adhesive

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.

Please note the use of Thermal Adhesives makes the PCB unlikely to be removed for servicing. Please consider this if removal of the board is desired as another TIM may be a better choice. 

Optics Support: The board can fit within Linear optics arrays like the Carclo 26.5mm series Optics with pins will allow for simple alignment and can be secured with a Chemically compliant adhesive.(see Cree Chemical compatible datasheet)

Termination: The PCB can be standalone or wired in groups in Series or parallel. The board is designed to be use with connectors and cable harness. Connector is a 10 pin Molex connector. The Led requires 8 pins(4 Cathode/4 Anode) the additional 2 pins are to address the on board 47k NTC, so for led drivers with thermal throttling capability, this will enable greater control of drive current relative to on board temperature.
