What is Aluminum base pcb board?
Aluminum base PCB board, also known as metal core PCB (MCPCB), is a type of printed circuit board that has a metal core layer made of aluminum or copper.
The metal core provides excellent heat dissipation properties, making it ideal for applications that require high power and high temperature resistance.

What Is Aluminum base pcb board?
Aluminum base PCBs are commonly used in LED lighting, power supplies, automotive electronics, and other high-power applications.
The metal core layer acts as a heat sink, dissipating heat away from the components on the board and preventing overheating.
Types of Aluminum base pcb board
- High thermal conductivity:
The metal core layer provides excellent heat dissipation, allowing for higher power applications. - High mechanical strength:
The metal core layer provides additional mechanical strength, making the board more durable and resistant to damage. - Lower thermal expansion:
The metal core layer has a lower coefficient of thermal expansion than FR4, reducing the risk of damage due to thermal stress. - Improved electrical insulation:
The metal core layer provides better electrical insulation than FR4, reducing the risk of short circuits and other electrical issues.
Overall, aluminum base PCBs are a reliable and effective solution for high-power and high-temperature applications that require excellent heat dissipation properties.
Multilayer metal core pcb
Multilayer MCPCB could layout more circuit, the MCPCB smaller much.
Applications Of aluminum pcb
The technology of the metal core PCB is ideal for its applications that generate immense heat and have difficulty being cool down using conventional fans or other cooling methods.
MCPCBs play an integral role to achieve a high illumination with fewer requirements than LEDs require.
The fabrication process of metal core PCB is helpful for the applications
Since the MCPCBs are most often used in LED technologies for producing a certain illumination the light-emitting diodes releases the heat in applications like:
– General lighting
– Automotive systems
– Industrial, telecom, power supplies, and high voltage regulators types of power converters
– Photovoltaic
– Street safety lightings and streetlights
– Backlight applications
Military and aerospace are another two other sectors appropriate to utilize the benefits of metal core PCBs in their applications.
These sectors are quite sensitive and need to endure frequent thermal cycling, limits of temperature and humidity, along with repeated mechanical shocks.
The MCPCB deals according to the operational requirements only if better structural veracity and thermal conductivity enabling withstanding greater shocks.
The higher the conductivity of thermal, the better it is for the temperature distribution throughout the boards as it ensures a uniform for thermal cycling.
It also stops forming hot spots before near to the active components.
Other than these, MCPCB works great in solar panels and motion control applications.
The combination of a metal core with HDI PCB technology can create an advanced circuit technology including microwave RF PCB, flex PCB, and rigid-flex PCBs.
As the demand for PCBs is high due to the remarkable benefits, the metal core PCB is the most widely used one among all the others.
It ensures high circuitry density, thermal management, and enhanced reliability for enhanced performance.

2 Layers direct thermal path copper core pcb application
2 Layers direct thermal path copper core pcb are designed to dissipate heat generated by high-power LEDs,
which helps to increase the lifespan of the LED and improve its performance.
The aluminium base acts as a heat sink, which absorbs and dissipates the heat generated by the LED.
The 2 Layers direct thermal path copper core pcb is made by laminating a thin layer of copper onto an copper substrate.
The copper layer is then etched to create the circuit pattern.
2 Layers direct thermal path copper core pcb for LED lighting applications are available in various sizes and thicknesses, depending on the specific requirements of the application.
They are also available in single-sided, double-sided, and multi-layered configurations.
