Description of Heavy Copper Printed Circuit Board Definition

A Heavy Copper Printed Circuit Board (PCB) is a type of PCB that has a thicker copper layer than standard PCBs. Typically, the copper layer on Heavy Copper PCBs is 3 ounces per square foot or higher, which is much thicker than the 1 to 2-ounce copper layers found on standard PCBs.The thicker copper layer allows for increased current-carrying capacity and better heat dissipation, making Heavy Copper PCBs ideal for high power and harsh environment applications. These PCBs are commonly used in power electronics, including inverters, motor drives, and power supplies. They can also be found in industrial control systems, aerospace and defense equipment, and automotive applications.
