MCPCB-XP203StarCU-IAD. This printed circuit board with Copper base has been developed for Cree XP size leds as well as Nichia 3535 and other 3535 leds. Designed for high thermal conductivity of 385 W/mK which is ideal for power LED lighting. This Metal Core PCB is manufactured with UL certified Copper substrates.
The MCPCB-XP203StarCU-IAD is designed to take three Cree XP style Led’s.
The board allows for individual die access for each Led and can also be wired in series with the on board solder links. Note the board also comes with resistor pads for on board limiting for additional control. Even if not required a Zero Ohm resistor will still be required if using series links for series operation
DIRECT Thermal Path : No Dielectric under the thermal pad of LED
The MCPCB-XP203StarCU-IAD 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.
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 is drilled to take various Optics such as the Ledil Satu or Carclo 105xx series*
Termination: The board has multiple pads in Cathode and anode to allow for wire clearance in multiple application
* some holders may require modifications to allow wire access to the PCB, Cutter assumes no responsibility for holder modifications
