Commonly Used Cores in Metal Core PCB

Omini offers a range of high-performance Metal Core PCBs, using various core materials to meet different application needs. The most commonly used cores in Metal Core PCBs are aluminum and copper, each with specific advantages based on thermal management, weight, cost, and mechanical strength.

Key Core Materials Used in Omini Metal Core PCBs:

1. Copper: Copper is used as the core material in Metal Core PCBs when extremely high thermal conductivity is required, such as in thermoelectric separation applications. It is also commonly found in multilayer, double-sided, and single-layer Metal Core PCBs. Copper offers higher mechanical strength than aluminum, making it ideal for applications requiring durability. However, its higher weight and cost can make it more challenging to manufacture. Due to these factors, copper core manufacturers are relatively rare.

2. Aluminum: Aluminum is the most widely used material for Metal Core PCBs. It offers good thermal conductivity (though not as high as copper), and it is lightweight, cost-effective, and easy to manufacture. Omini uses aluminum cores for a wide range of applications, especially in industries such as LED lighting where heat dissipation is critical. Additionally, aluminum alloys are also used for improved mechanical strength, though they tend to be slightly heavier and more expensive than standard aluminum.

Four Main Types of Metal Core PCBs

Omini specializes in providing a variety of Metal Core PCB options to meet the specific needs of different industries. Metal Core PCBs are distinguished by their unique stackup structure, which includes a metal core (usually aluminum or copper) combined with a dielectric layer and a copper circuit layer. Unlike other types of PCBs, the exposed metal core in these boards helps efficiently dissipate heat. The thickness of the metal core typically ranges from 1 mm to 1.6 mm, depending on specific requirements.

While most Metal Core PCBs feature a single copper layer, there are also multilayer options available, though manufacturers for these are relatively rare. Here are the four main types of Metal Core PCBs provided by Omini:

1. Single Layer Metal Core PCB: Copper – Dielectric – Core
The most common stackup, this type of Metal Core PCB consists of a single routing layer, making it the simplest and most cost-effective option. The metal core is isolated to a signal layer by the dielectric material, providing efficient thermal dissipation.

• Applications: Industrial relays, simple LED lighting solutions.
• Advantages: Cost-effective, easy to fabricate, ideal for basic applications requiring thermal management.

2. Thermoelectric Separation Metal Core PCB
This stackup is similar to a single-layer Metal Core PCB, but with a copper core. The core is designed to touch the body of the component without coming into contact with the component’s pads, which are insulated by the dielectric layer. This ensures high-grade thermal efficiency and electric isolation.

• Applications: High-power LEDs, specialized thermal management needs.
• Advantages: Superior thermal conductivity, ideal for high-power applications.
• Disadvantages: Expensive to fabricate, not suitable for simple LED solutions.

3. Double Layer Metal Core PCB
Type 1: Copper – Dielectric – Copper – Dielectric – Core
This type of Metal Core PCB includes an additional copper layer for routing, providing more compact and dense designs. It allows for vias to be used, enabling a more efficient layout.

• Applications: Power modules, audio equipment (e.g., amplifiers).
• Advantages: More routing flexibility, enables compact designs.

Type 2: Copper – Dielectric – Core – Dielectric – Copper
This version of the double-layer Metal Core PCB features exposed copper on both sides, allowing components to be placed on both sides of the PCB. This stackup reduces thermal dissipation while offering the flexibility of component placement.

• Applications: Legacy components such as hard disk drives, UPS systems.
• Advantages: Allows for component placement on both sides, good for high-density applications.
• Disadvantages: More difficult to fabricate compared to FR4 counterparts.

4. Multilayer Metal Core PCB
Multilayer Metal Core PCBs use multiple copper and dielectric layers between the surface copper and the metal core. However, due to the increased spacing and dielectric insulation, thermal management can degrade with more than 4 layers. Most Omini customers prefer sticking to 2 to 4 layers for optimal performance. Blind and buried vias can be incorporated into multilayer designs, though these increase the complexity and cost.

• Applications: High-end power modules, advanced thermal management solutions.
• Advantages: High-density designs with advanced features such as blind and buried vias.
• Disadvantages: Expensive, reduced thermal efficiency with increased layers.
