What is heavy copper PCB？

Heavy copper pcb is a printed circuit board (PCB) manufactured with 4 OZ copper or more , typically used in electronics and circuits that require high power transfer and good heat dissipation. Heavy copper boards ensure stable operation and extended life of electronic equipment by providing higher copper concentration and better thermal conductivity.

Construction features of heavy copper boards include four or more ounces of copper in each PCB layer, with copper concentrations as high as 200 OZ per square foot. This high concentration of copper provides excellent heat dissipation, which is critical for electronic devices that require high power transfer and good heat dissipation.

Advantage of heavy copper boards:

High power transfer: Heavy copper boards conduct heat efficiently, reducing the risk of equipment failure in high temperature environments.
Good heat dissipation: Heavy copper sheets provide impeccable thermal strength, ensuring that electronic devices remain stable in high-temperature environments.
Durability: Wiring platforms made of heavy copper plates are more durable and suitable for harsh environments and higher current operation.
Heavy copper boards are widely used in a variety of devices that require high power and high current, such as transformers, heat sinks, inverters, military equipment, solar panels, automotive products, welding equipment and power distribution systems. These applications require a high degree of board stability and heat dissipation, which heavy copper boards fulfil!
