Printed circuit boards carry current through copper wires. To enhance the ability of copper wires to carry current, one option is to widen the copper wires, and another way to increase the current carrying capacity without changing the width of the copper circuit is to use heavier or thicker copper.Standard Copper thickness for the Commercial printed circuit board is from 0.5oz to 2oz.The thickness of copper in heavy copper PCBs typically ranges from 3 oz(105um) to 10 oz(360um).
At the Professional heavy-copper PCB manufacturer Xinfeng Huihe Electronic Technology Co.,Ltd, the copper thickness capability of Heavy-Copper PCBs are from 3oz to 10oz.
Heavy copper PCBs are commonly used in applications that require high power or high reliability, the additional copper also provides greater mechanical strength and resistance to thermal stress, making heavy copper PCBs more durable and long-lasting.
Some specific fields where heavy copper PCBs are often utilized include:
1. Automotive Industry: Heavy copper PCBs are used in various components of automobiles, such as engine control modules, power distribution units, and battery management systems.
2.Aerospace Industry: These circuit boards are crucial for aircraft communication systems, radar equipment, and flight control systems due to their ability to withstand extreme conditions and high voltages.
3.Industrial Machinery: Heavy copper PCBs are essential for heavy-duty equipment like power supplies, motor controllers, and robotics, where reliable and efficient power transmission is essential.
Heavy copper PCBs play a crucial role in ensuring the performance and reliability of electronic systems in demanding applications across various industries.
The advantages of Heavy Copper PCBs make them a popular choice for a wide range of applications that require high current-carrying capacity, improved thermal management, and enhanced durability.
Heavy Copper PCBs help to improve thermal management capabilities. The thicker copper layers help to dissipate heat more effectively, reducing the risk of overheating and ensuring the overall reliability of the PCB. This is particularly important in high-power applications where heat dissipation is crucial for the proper functioning of the circuit.
Furthermore, Heavy Copper PCBs offer better mechanical strength and durability compared to standard PCBs. The thicker copper layers provide added support and stability, making Heavy Copper PCBs ideal for applications where the PCB may be subjected to high levels of vibration or stress.
