Title: Exploring the Advantages of Rocket-PCB’s Aluminum PCB

Rocket-PCB takes pride in offering cutting-edge Aluminum PCB solutions that leverage the advantages of aluminum-based copper-clad laminate technology. These metal PCBs combine a copper circuit layer, a dielectric insulation layer, and a metal substrate, creating a high-performance and versatile platform for various applications. In this article, we will delve into the features and benefits of Rocket-PCB’s Aluminum PCBs, highlighting their superiority over traditional FR-4 boards.

Aluminum-Based Copper-Clad Laminate Technology

The foundation of Rocket-PCB’s Aluminum PCB lies in the innovative aluminum-based copper-clad laminate technology. This unique material composition comprises three essential layers: circuit layer, dielectric layer, and base layer.

Circuit Layer: The circuit layer in an Aluminum PCB is akin to standard PCB copper clad laminates, with copper foil thickness ranging from 1oz to 10oz. This layer allows for efficient signal transmission and supports higher current carrying capacity.
Dielectric Layer: The dielectric layer is a crucial component in Aluminum PCBs, providing low thermal resistance insulation. With a thickness ranging from 0.003" to 0.006" inch, this layer is the core technology behind Rocket-PCB’s Aluminum PCBs and has received UL certification, ensuring reliability and safety.
Base Layer: Serving as the foundation, the base layer consists of a metal substrate, commonly aluminum or copper. This metal substrate distinguishes Aluminum PCBs from traditional epoxy glass cloth laminates and significantly contributes to their superior performance.

Advantages of Aluminum Base PCBs

Rocket-PCB’s Aluminum Base PCBs possess a range of advantages over traditional FR-4 boards, making them a preferred choice for various applications.

Thermal Conductivity: Aluminum is known for its excellent thermal conductivity, which is vital for dissipating heat generated by electronic components. Compared to FR-4 boards, Aluminum PCBs offer significantly higher thermal conductivity, exceeding 2.0 kW/(m.h.℃). This property ensures efficient heat dissipation and enhances the reliability and lifespan of electronic devices.
Electrical Insulation: Despite its metal composition, Aluminum PCBs maintain excellent electrical insulation properties. This characteristic is crucial for preventing short circuits and ensuring the proper functioning of complex electronic systems.
Mechanical Processing Performance: The low alloy Al-Mg-Si system high plastic alloy plate used in Rocket-PCB’s Aluminum PCBs contributes to their exceptional mechanical processing performance. This allows for ease of fabrication, making it easier to create intricate designs and meeting specific project requirements.
Higher Current Carrying Capacity: Thanks to the excellent thermal conductivity and unique material composition, Aluminum PCBs can carry higher currents compared to traditional FR-4 boards. This capability is essential for power-intensive applications where efficiency and reliability are critical.
High Withstand Voltage: Rocket-PCB’s Aluminum PCBs can withstand voltages of up to 4500V, providing an added level of safety and stability for high-voltage applications.

Rocket-PCB’s Aluminum PCBs stand at the forefront of advanced PCB solutions, harnessing the power of aluminum-based copper-clad laminate technology. With their superior thermal conductivity, electrical insulation, mechanical processing performance, and higher current carrying capacity, these PCBs cater to a wide range of applications, including power electronics, LED lighting, automotive systems, and more. By choosing Rocket-PCB’s Aluminum PCBs, customers can be assured of high-quality, reliable, and efficient electronic solutions for their projects.
