5 oz Heavy Copper PCB Custom Design

5 oz thick copper PCBs are used in high-power applications such as industrial control systems, power equipment, new energy products, and automotive electronics. These applications require high current capacity, better heat dissipation, and stable operation in demanding environments.

Compared with standard PCBs, 5 oz thick copper PCBs can carry larger current loads. The thicker copper layer also helps spread heat more effectively. This makes them suitable for high-current and high-temperature applications.

Manufacturing 5 oz thick copper PCBs requires strict process control. Trace etching, lamination, copper plating, drilling, and thermal stress control all affect board quality. Proper stack-up design and material selection are also important for long-term reliability.

Advantages of 5 oz Thick Copper PCB Products

High-power electronic systems have continuously increasing requirements for PCB current-carrying capacity and heat dissipation performance.

• The 5 oz thick copper structure can carry higher current, reducing circuit heating and voltage drop issues.

• The thick copper layer quickly diffuses heat, improving temperature rise control in high-power equipment.
