Heavy Copper PCBs: Power and Durability in Electronics

As the demands on electronic devices continue to increase, the need for printed circuit boards (PCBs) that can handle higher current and withstand harsh environments has become more crucial. Heavy Copper PCBs, also known as thick copper PCBs, have emerged as a powerful solution to these challenges. These specialized circuit boards feature copper traces and planes that are significantly thicker than those found in standard PCBs.

Delve into the details of heavy copper PCB.

In this article, we will explore the world of Heavy Copper PCBs, their construction, benefits, applications, and their pivotal role in powering and protecting electronic devices.

Understanding Heavy Copper PCBs

Heavy Copper PCBs are designed to handle high current and thermal loads, making them suitable for applications where reliability and durability are paramount. The defining feature of these PCBs is the increased thickness of the copper layers, which can range from 3 ounces per square foot (oz/ft²) to as much as 20 oz/ft² or more. This heavy copper plating enhances the PCB's ability to carry current and dissipate heat effectively.
