At R2T Industry, we specialize in manufacturing high-performance Metal Core Printed Circuit Boards (MCPCBs). The image above showcases our latest Custom Circular Aluminum PCB, specifically engineered for compact, high-lumen LED lighting fixtures.
Designed with a Single-Layer Aluminum substrate, this board offers superior heat dissipation compared to traditional FR4 boards, ensuring a longer lifespan for your LED components. It is optimized for SMD2835 LED packages, making it the ideal solution for residential and commercial lighting applications like recessed downlights and track spotlights.

Our aluminum substrates are designed to transfer heat away from the SMD2835 chips efficiently. This prevents thermal throttling and maintains color consistency over time.
As seen in the product image, our boards feature clearly marked polarity (+/-) and precise solder pads. This ensures high yield rates during the SMT (Surface Mount Technology) assembly process.
While this is a standard circular design, R2T Industry supports full customization. We can adjust the diameter, copper thickness (1oz - 4oz), and thermal conductivity (1.0W - 3.0W) to meet your specific engineering requirements.
This specific circular layout is widely used in:
Recessed Downlights: Perfect fit for standard round housing.
Track Lighting: High-density lighting for galleries and shops.
Ceiling Mount Lights: Uniform light distribution for offices.
Q1: What is the advantage of using an Aluminum PCB over a standard FR4 board for SMD2835 LEDs?
A: Aluminum PCBs have much higher thermal conductivity. SMD2835 LEDs generate significant heat; aluminum dissipates this heat quickly, preventing the LEDs from burning out and maintaining their brightness (lumen maintenance) for longer periods.
Q2: Can you assemble the LEDs onto this board (PCBA service)?
A: Yes, R2T Industry provides a one-stop service. We can handle the PCB fabrication, component sourcing (SMD2835 LEDs, resistors, connectors), and SMT assembly to deliver a fully functional PCBA ready for installation.
Q3: What surface finish do you recommend for White Aluminum PCBs?
A: For white solder masks, we typically recommend HASL (Lead-free) or ENIG (Electroless Nickel Immersion Gold). ENIG provides a flatter surface which is excellent for small components like SMD2835, ensuring better soldering quality.
Q4: Do you offer samples for testing?
A: Absolutely. We encourage clients to order samples to verify the fit and thermal performance before moving to mass production. Contact our sales team for a quick quote.
