Product Description

MCPCB-2835-20STR-AL: Premium Aluminium LED PCB Module

Discover unparalleled flexibility and performance with our MCPCB-2835-20STR-AL, a cutting-edge aluminium PCB designed to cater to your lighting needs. Engineered with precision, this module is the perfect host for a single LED with a base size of 3.0 × 3.0 mm, making it compatible with industry standards such as Cree 2835, along with other LEDs that share these base dimensions. Ensure you consult manufacturer data sheets to confirm compatibility.

Optimised Performance without Direct Thermal Path

The design uniquely incorporates a non-direct thermal path, with a dielectric layer beneath the LED’s thermal pad, optimising LED operation while dictating its performance based on the LED voltage. Attention to mounting and cooling is paramount to maintain the LED’s junction temperature significantly below its maximum threshold, as per the specifications provided by LED manufacturers.

Cooling and Mounting Solutions

For superior cooling efficiency, it is advisable to mount the MCPCB-2835-20STR-AL onto a suitable heat sink, ideally an aluminium flat plate, the thickness of which will vary depending on the total power consumption. Mounting options include:

• T-Tape Star Thermal Interface pads (Recommended)
• Graphite Thermal Pad(Fastener required) (Best Performance)

Before assembly, ensure the contact surfaces are impeccably flat and clean to maximise heat dissipation. The PCB’s bottom is electrically neutral, eliminating the need for electrical insulation from the cooling surface.

Considerations for Thermal Adhesives

The use of thermal adhesives may hinder the PCB’s removability for future servicing. Alternative thermal interface materials (TIMs) might be more suitable if board removal is anticipated.

Optics Support

This PCB supports a versatile range of optics, from 10mm to 30mm arrays. Optics can be securely attached using adhesives. For guidance on LED and optics assembly, including adhesive recommendations, refer to Ledil’s comprehensive assembly guide. Our Optics category

The PCB. is pre-drilled with 8.6mm pitch holes, so can be used with all Ledil Optics with pins on 8.6mm centres

Easy Termination and Configurability

Featuring anode and cathode pads, the PCB supports various configurations, whether as a standalone unit or wired in series or parallel groups, enhancing design flexibility for your lighting projects.
