Standard Aluminum PCB

Product Introduction

Standard Aluminum PCB is one of the most widely used metal-based circuit boards due to its excellent heat dissipation and cost-effectiveness. It is a type of metal circuit board made of copper foil, an insulating dielectric layer, and an aluminum core. Compared with traditional FR-4 PCBs, aluminum PCBs offer superior thermal conductivity, mechanical strength, and extended product lifespan, making them ideal for applications requiring efficient heat management.

Structure

A standard aluminum PCB typically consists of three layers:

1. Circuit Layer – Copper foil for electrical signal transmission.

2. Insulating Dielectric Layer – Provides thermal conductivity and electrical insulation.

3. Aluminum Base Layer – A metal substrate that efficiently dissipates heat to extend product durability.

Key Features

• Excellent Thermal Conductivity – Rapid heat dissipation reduces component operating temperatures.

• High Mechanical Strength – Aluminum base minimizes board warping, cracking, or bending during manufacturing and transportation.

• Environmental Protection – Free of harmful substances, safer for health and eco-friendly compared to traditional FR-4 boards.

• Long Service Life – Efficient thermal performance prevents overheating, extending product lifetime.

• High Current Capacity – Under the same width and thickness conditions, aluminum PCBs can carry higher currents than FR-4 boards.

Comparison with FR-4 PCB

• Heat Dissipation – Aluminum PCB has much better thermal conductivity, while FR-4 has limited heat resistance.

• Durability – Aluminum PCBs are less prone to deformation or cracking.

• Cost & Performance – Aluminum PCBs are more cost-effective for thermal applications compared to ceramic substrates, while offering better performance than FR-4.

• Layer Structure – FR-4 can be multilayered, while aluminum PCBs are mainly single-layer (though double-layer and multilayer aluminum PCBs also exist).
