Copper Coin-Embedded PCB
The name “embedded copper” implies integrating copper into the PCB stack-up. But what exactly is it? Let’s delve deeper into it!
What is Embedded Copper Technology?
Embedded copper technology is a technique used to integrate solid copper into the PCB layers. Copper, being an excellent conductor of heat, acts as a heat sink to enhance heat dissipation. It is particularly beneficial when placed beneath high-power components. Unlike other materials with decent thermal conductivity, such as aluminum or ceramics, copper possesses a unique combination of exceptional thermal and electrical conductivity . Embedded copper is widely used in power electronics, automotive aerospace, and telecommunications, where reliable heat management is crucial.
Now that we know why copper is preferred over other materials, how about the working principle?
Working Principle of Embedded Copper
The embedded copper coin, known for its excellent heat conductivity, facilitates the efficient transfer of heat from the component to the PCB. Acting as a thermal bridge, the copper coin quickly conducts the heat away from the component and transfers it into the PCB. Once within the PCB, the heat is distributed across its surface area,allowing for effective dissipation into the surrounding environment.
Copper coin an be incorporated into different forms and configurations. Two common types are buried and embedded copper coins.
Types of Embedded Copper
Buried copper coins are copper structures that are integrated within the inner layers of a printed circuit board. These coins have a thickness less than the total thickness of the board. While embedded copper coins can be placed either on the surface or within the layers of a printed circuit board. When positioned on the surface, these copper coins are visibly present. Alternatively, they can be strategically embedded within the layers of the PCB. In both configurations, embedded copper coins serve to establish direct thermal pathways and electrical connections between different layers of the PCB, promoting efficient heat dissipation and facilitating electrical conductivity.
While embedded copper PCBs offer various advantages, it’s important to consider potential drawbacks.
Potential Drawbacks
The implementation of embedded copper structures may add complexity to the PCB manufacturing process, impact the available space for routing traces and components, and increase costs. Therefore, when arranging your PCB layout, it’s crucial to carefully weigh these advantages and drawbacks to determine if embedded copper is the most suitable choice for your thermal management needs.
