MCPCB-3030-560-14LIN

Aluminium PCB for High-Density LED Applications: MCPCB-3030-560-14LIN

Overview

Designed for versatility and high performance, the MCPCB-3030-560-14LIN Aluminium PCB is tailored to support 112 high-brightness LEDs of type 3030, making it ideal for extensive lighting applications. The board dimensions are 560mm by 14mm. The board has two solder pads for termination

Optimal Thermal Management

The board incorporates a direct thermal path through a dielectric layer positioned under the LED thermal pads. This design ensures efficient heat dissipation, critical for maintaining the LED’s junction temperature well below its maximum rated value as per LED manufacturer specifications.

Cooling Recommendations

For optimal thermal performance, it is recommended that the PCB be mounted onto a suitable finned heat sink made of aluminium or copper that is exposed to open air. The mounting can be achieved through various methods, including:

• 560mm pressure sensitive, thermally conductive tape (Recommended)
• Thermal Compound: Requires the use of mechanical fasteners

Ensure that both mating surfaces are clean and flat before assembly to maximize heat transfer efficiency.

Mechanical Stability

Mechanical fasteners are recommended to secure the module robustly, ensuring stable and durable mounting. The base of the LED MCPCB is electrically neutral, which eliminates the need for electrical isolation from the cooling surface. When purchased in lots of 5, the boards come in a pre panelised array perfect for PICK and Place equipment, comes with built in fiducials

Optics Integration

This PCB is compatible with leading optics solutions from Ledil, Khatod, and Linear Optics, which can be adhered to the PCB using specific adhesives. For detailed assembly instructions, refer to Ledil’s generic guide on LED/optics assembly, available for Download

Electrical Configuration

The PCB features Anode and Cathode pads at its ends, supporting various wiring configurations including standalone setups or grouped in series or parallel arrays, enhancing design flexibility.
