What is aluminum pcb thickness?
The thickness of the aluminum substrate is related to its strength and durability. Thicker substrates are generally stronger and more durable, but also heavier and more expensive.
The thickness can also affect the performance of the substrate in certain applications, such as heat dissipation in electronics.

What Is aluminum pcb thickness?
The thickness of an aluminum PCB (Printed Circuit Board) can vary depending on the application and requirements.
Generally, the thickness of an aluminum PCB ranges from 0.5mm to 3.2mm. However, the most common thicknesses are 1.0mm, 1.5mm, and 2.0mm.
The thickness of the aluminum core is usually between 0.5mm to 2.0mm, while the copper layer thickness can range from 0.5oz to 6oz.
The thickness of the PCB is an important factor in determining the mechanical strength, thermal conductivity, and electrical performance of the board.
How to measure the thickness of aluminum substrate
To measure the thickness of an aluminum substrate, you can use a micrometer or a caliper. Here are the steps to follow:
- Clean the surface of the aluminum substrate to remove any dirt or debris.
- Place the micrometer or caliper on the surface of the substrate, making sure it is perpendicular to the surface.
- Gently close the jaws of the micrometer or caliper until they touch the surface of the substrate.
- Read the measurement on the scale of the micrometer or caliper. Make sure to take multiple measurements at different points on the substrate to ensure accuracy.
- If using a micrometer, make sure to zero it before taking measurements to ensure accurate readings.
- Record the measurements and calculate the average thickness of the aluminum substrate.
It is important to note that the thickness of the aluminum substrate can vary across different areas of the board.
Therefore, it is recommended to take multiple measurements at different points to get an accurate average thickness.
Aluminum substrate manufacturers are located all over the world. Some of the major locations for aluminum substrate manufacturing include:
- North America:
The United States and Canada are home to many aluminum substrate manufacturers, including Alcoa, Novelis, Aleris, and Kaiser Aluminum.
Major aluminum substrate manufacturers in Europe include Constellium, Norsk Hydro, and Granges.
China is a major producer of aluminum substrates, with companies like China Hongqiao Group Limited and China Zhongwang Holdings Limited.
Other Asian countries with significant aluminum substrate manufacturing capabilities include Japan (Kobe Steel and UACJ Corporation) and India (Hindalco Industries).
- Middle East:
Aluminium Bahrain (Alba) and Emirates Global Aluminium (EGA) are two major aluminum substrate manufacturers in the Middle East.
Overall, aluminum substrate manufacturers can be found in many different countries around the world, with production facilities located in areas with access to raw materials and transportation infrastructure.
Multilayer metal core pcb
Multilayer MCPCB could layout more circuit, the MCPCB smaller much.
This arrangement is made so that the heat can dissipate through the metal core and transmit to the chassis.
Most of the LED or analog devices are populated with considerably larger boards.
The surface of the boards finishes by dissipating the heat.
While using the MCPCBs, it is obliged to take proper caution because it is constructed with some complex and complicated metal layers laminated with FR4 based on glass material.
The chemistry for lamination differs while the board is fabricated.
If the board is bonded properly then there might be voids below the lamination and caution is necessary.
The dissipated fixture of heat is anticipated from the metal core which is needed to be defined and designed carefully.
Applications Of aluminum pcb manufacturer
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
– 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.
