The Growing Demand for Thick Copper PCBs in Modern Industries
Thick copper PCBs have become indispensable in the fast-evolving world of electronics. These circuit boards, characterized by copper layers thicker than the standard 1 oz, are engineered to handle higher current densities and extreme thermal conditions. From power electronics to automotive systems, their application continues to expand as industries demand robust and efficient solutions.
What Are Thick Copper PCBs?
Thick copper PCBs typically feature copper thicknesses of 2 oz or more, with some specialized applications requiring up to 20 oz. This extra thickness offers several advantages:
Enhanced Durability: Thick copper layers resist mechanical stress and wear, ensuring long-term reliability.
Improved Thermal Management: Excellent heat dissipation minimizes overheating, even in high-power environments.
Increased Current Carrying Capacity: Essential for applications requiring high power and current flow.
The combination of these features makes thick copper PCBs ideal for industries where performance and reliability are critical.
Applications of Thick Copper PCBs
Automotive Electronics Electric vehicles (EVs), advanced driver-assistance systems (ADAS), and charging stations rely heavily on thick copper PCBs. Their ability to handle high power and dissipate heat effectively ensures the safe operation of these systems.
Power Supply Units In high-voltage power supplies, thick copper PCBs provide the stability and durability needed to manage large currents without performance degradation.
Industrial Equipment Thick copper PCBs are used in motor controllers and heavy-duty machinery, where they withstand harsh operational conditions and deliver consistent performance.
