What is Copper Based PCB
Copper based PCB is a kind of metal core PCB that utilizes copper as its base material. It is featured with great thermal conductivity and heat dissipation, but the cost of it is much expensive. It is suitable for applications that require high frequency circuits, and the ability to withstand great temperature changes such as some complicated electronic devices. In addition, copper based PCB has a high demand for current carrying, thus, thick copper foil is required. Normally, the thickness of the copper foil is from 35μm to 280μm.
According to different surface finish manufacturing processes, copper based PCB can be classified into various types:
• Hot Air Solder Level(HASL) Copper Based PCB
• Immersion Gold Copper Based PCB
• Thermoelectric Separation Copper Core PCB
• Silver-plated Copper Core PCB
• Immersion Silver Copper Based PCB
• Anti-oxidation Copper Core PCB
• Immersion Tin Copper Base PCB
The Advantages of LED Copper PCB
Excellent Electrical Performance
Thanks to its excellent electric performance, LED copper PCBs are perfect for high-frequency applications and precision equipment.
High Thermal Conductivity
LED copper PCB has high thermal conductivity. There is no need to use heat sinks as the copper base can dissipate heat with high efficiency. By applying such PCB, the devices can be used for a longer time. Therefore, it is a good choice for those projects where the end-use environment is high temperature.
Shape Retainment
Unlike FR4 PCB which would be bent in high-temperature conditions, copper core PCB can retain the shape and its dimension even in harsh environments such as high temperature and pressure.
Durability
Compared to other metal core PCBs like aluminum and iron-based PCBs, it has better durability thanks to its great mechanical strength that helps to lengthen the lifespan of the PCB and other components. So, copper core PCBs are not easy to wear and tear.
Key Considerations for Copper Based PCB Design
First, we need to consider the line width and spacing, which is actually decided by the thickness of copper foils on the PCB. If the copper foil is thick, then the line width needs to be designed wider, and the minimum spacing needs to be larger. In addition, we should notice that the minimum drilling diameter of copper core PCBs should be 0.4mm.
Second, when designing the copper core PCBs, the external force and vibration that they may withstand during working should be considered as well. Thus, we need to design the size and position of the holes on the circuit board accordingly, making sure that they can bear the bending strength.
Last, when designing complicated copper based PCBs, we also need to consider other aspects including routing, assembly, heat, signal, and aesthetics.
