Metal core PCBs

Metal core PCBs (MCPCBs) are becoming popular for LED lighting applications. They have specific properties good for LED lighting, such as thermally stable and electrically insulating. These boards are composed of aluminum or an aluminum alloy. These boards are becoming the industry standard.

The plastic body of a LED package dissipates most of the heat from the LED, and metal leads are typically thin and of limited cross-section. Their limited capacity to dissipate heat limits the amount of light and power produced from a given LED. However, this is not to say that you can’t use the metal leads.

Aluminum PCB board for LED Thermal conductivity

Thermal conductivity of aluminum PCB board for LEDs is important in choosing the right material for your project. LEDs are electronic devices that convert electrical energy into light. Consequently, they generate heat, dissipating into the circuit board, pins, and metal boxes. Aluminum is much slower than copper, but it can still dissipate heat. Aluminum’s thermal conductivity depends on the PP layer, composed of a polymer filled with ceramics. Aluminum laminate makers maintain a secret formula, which is the main factor in determining the thermal conductivity of aluminum circuit boards.

Aluminum-based PCB boards are the most common metal substrate for LED lighting. While copper-based boards are more stable than those made from FR4 PCB, they have some limitations. For example, a typical aluminum-based PCB board can reach temperatures of 150 degrees Fahrenheit and bend or distort by up to 2.5 percent.

Thermal conductivity of aluminum PCB board for LEDs is a critical factor for the longevity of an LED product. The higher the thermal conductivity of an aluminum-based PCB board, the longer it will last. It also reduces the breakdown voltage, which is an important factor for LED lighting.

Aluminum-based PCB boards have excellent thermal conductivity but not as high as copper-based boards. While copper-based boards tend to have a higher thermal conductivity, aluminum-based boards are unique metal-based copper-clad aluminum substrates. These high-density multilayer PCB boards are difficult to heat-dissipate due to their density and power.


A lightweight aluminum PCB board for LED is a great choice for LED lights. Aside from being lightweight, an aluminum board will also keep the LEDs cooler. In addition, these boards can also supply visible, infrared, and even ultraviolet light. This means that they are more energy-efficient than most other light sources.

LED lights are also great for the environment. They do not contain mercury and have a much lower environmental impact than standard light bulbs. In addition, LED PCBs are extremely inexpensive. Because of their lightweight, they are also easy to handle. Additionally, they demonstrate an amazing degree of dimensional stability.

Aluminum is also recyclable, making it an environmentally friendly option. Additionally, it will increase the lifespan of the PCB because aluminum can move heat better than other materials.

Another key factor is the dielectric, a thin thermally conductive layer bonded to the aluminum substrate. This helps to dissipate heat and separates the aluminum from the rest of the electrical layout.

Another benefit of LED PCBs is their flexibility. Unlike traditional PCBs, you can shape LED PCBs to meet specific design specifications. Their flexibility and durability make them a preferred choice for manufacturers.

Electrical insulation

The base layer of the LED PCB is typically aluminum, or copper foil etched to form the printed circuit. This layer provides electrical isolation and minimum thermal resistance. It also bonds the circuit layer to the base material, which is typically aluminum or copper. The thickness of the dielectric layer varies depending on the materials used. The most common dielectric layer thickness is 0.040″ (1.0mm) and the base layer thickness is 0.2-5.0mm.

An LED PCB consists of several layers. The base layer consists of an aluminum alloy sheet. There is also a layer of thermal insulation made of ceramic polymer. This layer protects the LEDs from thermal damage and transfers the heat away from the LEDs. Finally, there is a circuit layer composed of copper circuits. The number of layers depends on the design of the LED PCB.
