Top 10 Heavy Copper PCB Factory in the world 2025

Introduction to Heavy Copper PCB

Heavy Copper PCB, also known as thick copper PCB, is a specialized type of printed circuit board that features copper layers with a thickness greater than the standard 1 - 2 ounces per square foot (oz/ft²). Typically, heavy copper PCBs have copper thicknesses ranging from 3 oz/ft² up to 20 oz/ft² or even more. This increased copper thickness provides several significant advantages over traditional PCBs.

One of the primary benefits of heavy copper PCBs is their enhanced current - carrying capacity. With thicker copper traces, they can handle much higher currents without overheating, making them ideal for high - power applications such as power supplies, electric vehicle charging systems, industrial machinery, and high - power amplifiers. Additionally, heavy copper PCBs offer better thermal conductivity. The thick copper layers can effectively dissipate heat generated during operation, which helps to improve the reliability and lifespan of the electronic components mounted on the board. Moreover, they provide greater mechanical strength, which is crucial in applications where the PCB may be subject to vibration, shock, or other physical stresses.
