What is Metal Core Printed Circuit Board?



According to MCPCB manufacturer, a Metal Core Printed Circuit Board contains metal as the base material. The idea of using a metal at the core is to redirect the heat away from the part that generates a significant amount of heat.

The Metal Core Printed Circuit Boards use the base metal in order to increase the thermal conductivity. This concept is not common in the standard circuit boards, where they use CEM3 or FR4 as the base material. The core is made up of a metal plate. The plate is thick enough to dissipate heat in an effective and efficient manner.



Three Base Materials for PCB - MCPCB manufacturer


According to the MCPCB manufacturer, there are three main metals that they use as the base material for the MCPCB including Iron, Copper, and Aluminum. The difference in the peculiar properties of the metals makes them suitable for different applications.

Aluminum is famous among the LED MCPCB manufacturer mainly because of the cost element. Aluminum is cheap in comparison to the other two metals. Besides being affordable, Aluminum comes with an excellent heat-dissipating and transferring ability.

Copper, on the other end, has better performance, but it also has a direct impact on the price. A Copper-based MCPCB is significantly more expensive in comparison to an Aluminum one. Steel is another option; it is more rigid and very low thermal conductivity.

Below is a brief introduction to all three Metal Core Printed Circuit Boards


Aluminum PCB


MCPCB Manufacturers


As we already mentioned that Aluminum is common among the LED MCPCB manufacturers. The basic structure of Aluminum PCB is as follows:


Circuit Layer


The first layer is the circuit layer, it is a printed circuit copper foil layer. The thickness of the layer greatly depends on you. It can range from 1.0oz to around 8 oz. The minimum trace or trace will be 5/5mil


Dielectric layer


Then comes the direct layer. The price has a significant decrease if you opt for affordable and cheap Chinese PCB manufacturer.  It is important to choose the right manufacturer, as it will define the life and the quality of the PCB.


Substrate Layer


For a substrate layer, the MCPCB Circuit manufacturer uses four different types of Aluminum including 6061, 5052, 3001, and 1001. You as the potential buyer can decide the type you want. If there is no requirement, most manufacturers use 5052 due to its high thermal conductivity and affordability.


Copper Core PCB


Next, we have the Copper Core PCB. The PCB offers more rigidity in comparison to the other two. The copper PCB is about the substrate, insulating layer and copper. Like Aluminum, Copper PCB also comes in varies types and forms.

The MCPCB manufacturer uses a unique process called the laminated disposition in order to create a copper PCB. The process makes it possible for an extreme copper thickness requirement to become, cost-efficient and extremely practical.

To deliver high quality, consistency and high power circuit boards, the manufacturer utilizes a good amount of copper. Despite being used in abundance, copper makes it possible to create finer lines, well-defined edges, refined tracks and finer spaces.


Iron-Based PCB


The base material in the metal core PCB is from special steel including stainless steel, silicon steel, etc. The iron-based PCB has the capability to dissipate heat away from the circuit board and transfer to areas that are less critical such as the metal heatsink backing or the metallic core.

Manufacturing of iron PCB is a tricky task, however, KingPCB, are a professional MCPCB manufacturer. They are able to develop a robust and lasting iron-based PCB in no time.



Why Metal Core PCBs are important? - MCPCB manufacturer


The developing technology has led to a significant decrease in the size of electronics, while a definite increase in their functionality. In order to meet the demands of the modern days, MCPCB Circuit Manufacturers are using metal core PCB instead of the standard ones.

The decrease in size somehow has an impact on the amount of heat the electronics produce. Therefore, it is important to have circuit boards that have an innate ability to dissipate heat and transfer it to less critical areas.

Since the main purpose of the metal core PCB is to dissipate heat and act as an excellent heat thermal, thus, they are extremely important for contemporary electronics. By sustaining the heat and maintaining the optimum level of performance, MCPCB increases the lifespan of the components.

This in result boosts the performance of the electronics and makes them robust. A Metal Core Printed Circuit Board is about eight times more efficient in comparison to the regular FR4 PCB. MCPCB manufacturer understands that general cooling method such as the fans is not efficient in terms of applications that generate a lot of heat.  Therefore, they need solutions that are more reliable.

For this reason, they now use metal core PCB instead of the standard PCBs. They firmly believe that Metal Core Printed Circuit Boards are excellent heat conductors and heat dissipaters.


 Advantages of Metal Core MCPCBS


A Metal Core PCB is the first choice for many modern, affordable and cheap PCB manufacturers. They believe that metal core Printed Circuit boards offer reliability, affordability, and efficiency when compared to the other types of PCBs.

Metal Core Printed Circuit boards offer a number of benefits, and below we have briefly discussed these advantages.




MCPCB especially the aluminum core PCBs are extremely cost-effective. Since Aluminum is among the few materials that can withstand almost all types of climates, thus it offers longevity and durability. In addition, the Aluminum production process is affordable.

MCPCB manufacturer says that mining and refining of Aluminum are cost-efficient. Thus, it reduces the overall production cost of the printed circuit board. An affordable substrate will lead to a cheap PCB, then in result allow you to offer competitive prices to your consumers.

After all, consumers are always looking for products with low prices, offering high-quality functionality. Metal Core PCB offers the best of both worlds, i.e. you will get a robust and reliable application at less price in comparison to the applications using standard PCBs.


Heat Dissipation


Another major advantage of a Metal Core Printed Circuit Board is its ability to dissipate heat in an effective and efficient manner. Since heat reduction and transferring is a challenging task especially for double-sided Printed Circuit Boards and for Multi-Layer Printed Circuit boards, therefore, they need to incorporate material that is excellent heat dissipater.

The standard PCB’s material does not have the ability to withstand extreme heat. They are not good conductors nor do they have good heat insulation techniques. The lack of heat dissipation and thermal conductivity leads to failure of the component, which then affects the performance and life-span of the application.

Using a Metal Core PCB, you will not face issues like thermal Throttling, as metals are excellent thermal conductors and heat dissipaters. All three metals used in the MCPCB are outstanding heat conductors and they efficiently transfer the heat to less crucial areas. Effective heat transfer decreases the chances of component failure and increases the lifespan of the applications tremendously.


Strong and Durable



Another advantage of using metal for PCB is that they offer durability. These PCBs are extremely strong, in comparison to the fiberglass. The metal PCBs are perfect for an application that requires strong stress resistance and mechanical stability.

A fiberglass PCB may not be able to dissipate heat properly, thus leading to application failure. Metal Core PCB, on the other hand, will ensure that the applications are able to withstand high temperatures. Likewise, dealing with metals is easier, as they are less likely to be subjected to damage during manufacturing or handling.

Even the day to day use of the application becomes more robust due to metal core PCBs. Durability is the reason, that the LED industry now prefers LED MCPCB manufacturers. They firmly believe that these LEDs using MCPCB are strong and reliable.


Resistance to Thermal Expansion



Most of you might be familiar with the concept of thermal expansion, however, for people who are unaware, below is the formal definition.

Thermal Expansion is a process in which a material expands when the heat is applied to it. After the material cools down, it comes back to its original size.

The continuous expansion and contraction of the material decrease its resistance power and it weakens over time. Thus, the heat dissipation process becomes ineffective. Lack of Thermal expansion is another factor of these metals especially aluminum that increases the reliability factor of the metal core printed circuit boards.

Since metal is less prone to thermal expansion, therefore it has a longer life and offers robustness in comparison to the regular core substrates including Fiberglass and Ceramic.



Lightweight Material



Lightweight is among the leading seasons for MCPCB manufacturers to use metal as the core material for Printed Circuit Boards. All three metals are light in weight, thus they add very little to the overall weight of the circuit board.

These metals add more resistance, strength, and durability to PCB without bringing unnecessary weight. In addition, these lightweight metals improve the quality of the product and are mechanically very strong. Thus, they are the best choice when it comes to adaptable circuit boards.

Metals especially aluminum are extremely flexible. You can use it in its liquid form or even after solidifying it. The metal remains substantial and durable in all forms.

Eco-Friendly Manufacturing


One of the major reasons for using metal core Printed Circuit boards is that they are extremely environment-friendly. The metal circuit boards are not only, non-toxic, but they are fully recyclable as well.

After you are done with the Printed Circuit board, you can always reuse the metal inside for another purpose. Using metal also conserve energy, as the manufacturing and assembling process requires less time and energy.  Therefore, KINGPCB, a leading MCPCB Circuit manufacturer prefers metal core printed circuits boards.


Application of Metal Core PCBs


Metal Core Printed Circuit Boards are imperative for certain applications. For instance, products that use Solid State lighting need to use MCPCB to perform effectively and to retain longer shelf life. Likewise, devices that generate a high amount of heat such as the High Power Light-Emitting Diodes (HP LEDs) or the Lighting Emitting Diodes (HP) should use metal core PCB in order to dissipate the heat.

The amount of heated generated by these devices will have an adverse impact on their performance provided if the heat is not managed properly. Proper diversion of the heat from the critical component of the LED will increase its lifespan and enhance its performance.

MCPCB applications are unlimited, they are commonly seen in computer backlight LCD displays, notebook LCD displays, Desktop displays, general lighting, industrial monitoring systems, and automotive lighting.

MCPCBs are also common in the electric motor control application, hybrid motor control application and photovoltaic. They are also part of different power converters including high voltage regulator, telecom, power supplies, and industrial power needs.
