MCPCB-XR-MR11-32

Overview of 32mm Round MCPCB for Cree XRE LEDs

Exceptional Design and Quality

The 32mm Round MCPCB, model MCPCB-XR-MR11-32, is a specialised printed circuit board designed exclusively by Cutter Electronics. Featuring an aluminium base, this PCB is tailored for rapid prototyping of LED modules utilising Cree XRE LEDs. Its high thermal conductivity of 2 W/m.K ensures efficient heat dissipation through the aluminium substrate, making it an optimal choice for LED lighting applications.

Certified and Reliable Materials

Crafted from UL-certified aluminium substrates, this Metal Core PCB guarantees durability and safety, complying with stringent quality standards. The board is engineered to support four Cree XRE LEDs, providing a robust platform for high-performance LED applications.

Innovative Thermal Management

A critical feature of the MCPCB-XR-MR11-32 is its advanced thermal path, which includes a dielectric layer under the thermal pad of the LED. This design aids in maintaining lower junction temperatures, significantly extending the lifespan of the LEDs. To further enhance cooling, the module should be mounted to a suitable finned heat sink, either aluminium or copper, which is exposed to open air.

Mounting and Cooling Solutions for MCPCB-XR-MR11-32

For effective attachment, the module can be mounted using 32mm pressure-sensitive, thermally conductive tape or via thermal compounds requiring mechanical fasteners. It is important to ensure that the surfaces are clean and flat before mounting to maximise heat transfer.

Electrical Safety and Optics Compatibility

The base of the LED MCPCB is electrically neutral, which simplifies the mounting process as there is no need for electrical isolation from the cooling surface. The board also features compatibility with Ledil Cute series optics in a 35mm Quad format, supporting a range of beam shapes from narrow to wide.

Considerations for Maintenance

It is recommended to carefully consider the choice of thermal interface materials (TIM), as the use of permanent thermal adhesives could complicate future servicing or removal of the PCB.
