About Aluminum PCB:

Focus on high thermal conductivity & high-performance Aluminum PCB

An Aluminum PCB is a metal-based, copper-clad board with excellent heat dissipation properties. Typically, a single panel consists of three layers: the circuit layer (copper foil), the insulation layer, and the metal base layer. used frequently in LED lighting products. There are two sides, with LED pins soldered to the white side and the original color of Aluminum on the other side, which is often covered with thermally conductive condensate following contact with the thermal conductivity component.

Construction of an Aluminum PCB

Line layer

The circuit layer (generally electrolytic copper foil) is etched to form the printed circuit for device assembly and connection. Compared to conventional FR-4, the Aluminum substrate is capable of carrying higher currents with the same thickness and the same line width.

Insulation Layer

The insulation layer is the core technology of Aluminum substrate, mainly for bonding, insulation, and thermal conductivity. The insulation layer of Aluminum substrate is the largest thermal conductivity barrier in the structure of power modules. The better the thermal conductivity of the insulation layer, the better it is for the diffusion of heat generated by the operation of the device, and the better it is for reducing the operating temperature of the device, thus increasing the power load of the module, reducing the volume, extending the life, and increasing the power output.

Metal base

The metal used for the insulating metal substrate depends on the coefficient of thermal expansion, thermal conductivity, strength, hardness, weight, surface condition, and cost of the metal substrate.

In general, an Aluminum sheet is an ideal choice in terms of cost and technical performance. The available Aluminum sheets are 6061, 5052, 1060, etc.

The Advantages of Aluminum PCB

aluminium circuit board

Aluminum PCBs have good thermal conductivity, electrical insulation performance, and mechanical processing performance. Compared with traditional FR-4, the Aluminum substrate can carry a higher current with the same thickness and the same line width, Aluminum substrate can withstand voltages up to 4500V and thermal conductivity of more than 2.0.

1.More adaptable to the SMT process.

2.In line with RoHS requirements.

3.The heat dissipation has been effectively processed to reduce the module operating temperature, extend the service life and improve reliability.

4.The volume is reduced, reducing the assembly area of the heat sink and other hardware (including thermal interface materials), reducing the size of the product, and reducing hardware and assembly costs.

5.Mechanical endurance is good, compared to some simple processes to produce ceramic circuit boards.

Applications of Aluminum PCB Board

Audio equipment

Audio Equipment

input, output amplifier, balanced amplifier, audio amplifier, preamplifier, power amplifier.

Power supply

Power Supply

switching regulator, DC/AC converter, SW regulator, etc.Communication electronic equipment: high-frequency amplifiers, filtering appliances, transmitting circuits.Office automation equipment: motor drivers, etc.


Rigid PCBs are commonly found in small electronic devices such as cell phones, tablets, cameras, video recorders, and other similar small gadgets on the market today. Because these products are frequently transported or handled, the Rigid PCB’s resistance to shock and vibration is an important feature.

Lamps and Lighting

As advocates of energy-saving lamps, a wide variety of colorful energy-saving LED lamps are popular in the market, and Aluminum PCBs for LED lamps are beginning to be used on a large scale.
