Aluminum PCB is one type of metal-core printed circuit board (MCPCB), widely used in the LED lighting industry.
Aluminum PCB consists of a dielectric metal base with a bonded copper circuit layer to create superior heat transfer to help cool components while eliminating problems associated with managing fragile ceramics.
Applications of Aluminum PCB:
General lighting applications (Streetlight, Flashlight, Spotlight, etc.)
Backlight unit applications
System automotive LED applications
Power converters: telecom, high voltage regulator, power supplies
Hybrid/electric motor control applications
What are the Different Types of Aluminum PCBs?
As said earlier, selecting the type of aluminum circuit board depends largely on the application for which it is used. There are three main types of aluminum PCBs as follows:
1. Through-hole Aluminum PCBs
In the through-hole aluminum circuit boards, the aluminum is pre-drilled. After that, a dielectric is backfilled into the hole.
2. Flexible Aluminum PCBs
In these PCBs, flexible dielectrics are used, which provide a high level of flexibility, thermal conductivity, and electrical insulation. When these dielectrics are used with aluminum material, the product thus formed is highly flexible and can be formed in different shapes. This helps eliminate costly connectors and fixtures.
3. Hybrid Aluminum PCBs
These types of aluminum PCBs are generally used in RF applications and are known to provide better thermal performance when used in a standard FR4 product.
Why is Aluminium Used in Circuit Boards?
Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board.
Higher durability: Aluminum provides strength and durability to a product that ceramic or fiberglass bases cannot.
