Best China Aluminum PCB Manufacturer

Aluminum printed circuit boards are also known as metal base PCBs, and are comprised of metal-based laminates covered by copper foil circuit layers. They are made of alloy plates that are a combination of aluminum, magnesium and silumin (Al-Mg-Si). Aluminum PCBs deliver excellent electrical insulation, good thermal potential, and high machining performance, and they differ from other PCBs in several important ways.

  • The base layer consists of an aluminum alloy substrate. The use of aluminum makes this type of PCB an excellent choice for through-hole technology.
  • The thermal insulation layer is a critically important component of the PCB. It contains a ceramic polymer that has excellent viscoelastic properties, great thermal resistance, and defends the PCB against thermal and mechanical stresses.
  • The circuit layer contains the copper foil mentioned previously. Generally, PCB manufacturers use copper foils ranging from one to 10 ounces.

The dielectric layer of insulation absorbs heat as current flows through the circuits. This is transferred it to the aluminum layer, where the heat is dispersed.

Every rigid and flexible printed circuit board (PCB) design is different, customized to meet the board’s purpose. The same is true for the PCB base material — fiberglass is a popular base material, but aluminum-based PCBs are also very effective in many applications. Aluminum PCBs consist of a metal-based, copper-clad laminate that delivers high performance, including excellent thermal conductivity and electrical insulation.

Benefits of Aluminum-Based Printed Circuit Boards

Metal core PCBs have a unique set of advantages compared to other base materials:

Less expensive. Aluminum is indigenous to a variety of climates, so it’s easy to mine and refine. That makes it significantly less expensive to mine and refine than other metals. By extension, the manufacturing costs associated with products using aluminum PCBs are also less expensive. Aluminum PCBs are also a less expensive alternative to heat sinks.

Friendly to the environment. Aluminum is a non-toxic, recyclable metal. From the manufacturer through to the end consumer, using aluminum in PBCs contributes to a healthy planet.

Better heat transfer. High temperatures are the cause of heavy damage to electronics. Aluminum conducts and transfers heat away from critical parts to minimize damage to the printed circuit board.

Very durable. Aluminum is stronger and more durable than base materials like ceramic and fiberglass. It is very sturdy, and reduces accidental breakages that can occur throughout the manufacturing process, and during handling and everyday use.

Lightweight: Considering its durability, aluminum is very lightweight. It adds strength and resilience to PCBs without adding additional weight.

We like our clients to be as informed as they can about the different types of products we offer at EastwinPCBA. Even though power converters and lighting projects are the largest users of metal-based PCB’S, there are many different uses. LED PCB manufacturers make up the majority of metal-based circuit boards, , it may benefit from the advantages of aluminum-core PCB material. Every Aluminum core PCB supplier should help their customers assess their needs for thermal control and insulation.  Aluminum Core PCB’s are typically used with White or Black solder mask and for LED applications.
