Custom Linear Aluminum PCB for High-Output LED Tube Lights R2T Industry(H.K) Ltd.

High-Performance Custom Linear MCPCBs for Next-Gen LED Tube Lights

Product Overview

In the demanding world of linear lighting and LED tube retrofits, thermal management is the key to longevity. Our Custom Long Strip Aluminum PCBs are precision-engineered specifically for high-density T8, T5, and commercial linear lighting fixtures.

Whether you are manufacturing high-lumen T8 retrofits, industrial linear bays, or decorative LED light bars, our MCPCBs provide the stable thermal foundation your SMD LEDs need to maintain peak lumen output for over 50,000 hours.

Why Thermal Efficiency Defines Your LED Tube Lifespan

LED tube lights operate in enclosed spaces, generating significant heat. Standard FR4 boards will fail under these conditions. Our aluminum-based MCPCBs utilize a highly conductive thermal substrate and a 1oz copper layer that acts as an integrated heat sink. This design rapidly pulls heat away from the LED die, preventing catastrophic thermal decay and ensuring your lights stay bright for years.

⚙️ Tailored Engineering for Your Linear Fixtures

We don't believe in one-size-fits-all. Our OEM/ODM capabilities allow us to customize every aspect of your linear PCB:

Custom Lengths & Row Configurations: From dual-row T5 tubes to multi-row high-bay linear lights, we tailor the board to your fixture's exact dimensions.

Flexible LED Compatibility: Our pad designs perfectly accommodate high-power SMD 2835, 5730, 5630, and 2216 LEDs.

SMT Ready Manufacturing: With precise HASL/ENIG surface finishes and strict tolerances, our boards are 100% ready for high-speed, zero-defect SMT mass production.

1. How do aluminum linear PCBs improve the lifespan of T8 LED tube lights?

Unlike traditional FR4 boards, aluminum linear PCBs use a metal substrate that acts as an integrated heat sink. Since T8 tubes are enclosed, heat builds up quickly. Our MCPCBs rapidly dissipate this heat, preventing the SMD LEDs from overheating. This significantly reduces lumen depreciation (light decay) and extends the operational lifespan of the tube light well beyond 50,000 hours.

2. Can I customize the length and circuit layout for my specific linear lighting fixture?

Absolutely. We specialize in OEM/ODM customization for linear lighting. We can cut the aluminum substrate to your exact required length (typically up to 1.2m for standard T8s, or longer for custom linear bays) and engineer the circuit layout to match your specific number of parallel LED rows and driver voltage requirements.

3. Which SMD LED packages work best with long strip aluminum PCBs?

Long strip MCPCBs are highly versatile and support most standard high-power SMD packages used in linear lighting. Common compatible options include SMD 2835 for budget-friendly T8 retrofits, and SMD 5730 or 5630 for high-lumen commercial linear bars. We can customize the SMT pad size and spacing to match your specific component sourcing.

4. What surface finishes do you offer for linear LED PCBs?

For linear LED tube manufacturing, we typically offer Lead-free HASL (Hot Air Solder Leveling) and ENIG (Electroless Nickel Immersion Gold). HASL is the industry standard for T8/T5 tubes due to its excellent solderability and cost-efficiency for mass production, while ENIG is recommended for high-end linear fixtures requiring superior surface flatness.
