What is Aluminum PCB boards?

What is Aluminum PCB boards?

Common in LED lighting products. There are positive and negative sides, white side is welding LED pin, the other side of the aluminum color, usually coated with thermal conductivity condensate after contact with the thermal part.

Oneseine Aluminum PCB boards have a good heat dissipation function of the metal-based CCL, generally the single-sided panels consist of the three-tier structure, namely the circuit layer (copper foil), insulation and metal substrate. For high-level using also designed for the double-sided layer, the structure of the circuit layer, insulation layer, aluminum, insulating layer, circuit layer. A very small number of applications for the multilayer, can be an ordinary multilayer and insulating layer, aluminum fit together.

LED aluminum substrate is the PCB, but also the meaning of printed circuit board, but the circuit board material is aluminum alloy, the general material of our previous circuit board is fiberglass, but because the LED heat larger, so LED lamps with the circuit board is generally Aluminum plate, to heat quickly, other types of equipment or electrical use of the circuit board or glass plate

The advantage of aluminum PCB boards?(VS FR4)

Compared with the traditional FR-4, the aluminum PCB boards can minimize the thermal resistance, so that the aluminum boards with excellent thermal conductivity.

Compared with the thick-film ceramic circuit, its mechanical properties and extremely good.

In addition, the aluminum PCB boards has unique advantages as follow:

Rohs meet the requirements;

More suitable for SMT process;

Have effective treatment in the circuit design of the thermal diffusion, thereby reducing the module operating temperature, extend the service life, improve power density and reliability;

Reduce heat sink and other hardware (including thermal interface materials) assembly, reduce product size,hardware and assembly costs;power circuit and control circuit to optimize the combination;

Replace the fragile ceramic substrate, for better mechanical durability.

How Are Aluminum PCBs Made?

A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric.

Aluminum printed circuit boards Contain a Thin Layer of Thermally Conductive Dielectric Material that Transfers Heat

There are many names for these products; Aluminum clad, aluminum base, Metal clad printed circuit board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etc… but they all mean the same thing and perform the same way.

Are you looking for an Aluminum Base PCB?

Oneseine PCB is committed to providing the highest quality PCBs that not only meet but exceed our customers’ expectations. We can be your best source to buy an Aluminum Base PCB board whenever you need it. Our printed circuit boards are of IPC Class II or higher depending on your requirements.

We are experienced in the manufacture of aluminum PCBs for years. We do not skimp on quality. An Aluminum Base PCB from us will easily help you control the heat that is generated by the devices you want it for, reduce costs in PCB dimensions and spare you from having to resort to bulky heatskins. In addition, the thin dielectric draws heat away from the circuit. This way, your Aluminum Base PCB allows you to

Reduce thermal wear and tear on all components as well as make your devices more durable.

Lower operating temperature

Increase power output

Aluminum boards are widely used in LED and other lightings.

We use both Bergquist and Dongli material to make aluminum PCBs of the highest quality!
