Heavy copper PCB has another name, thick copper PCB, containing more than 3 ounces (oz) of copper on the inner or out layers of printed circuit boards. The circuit board with a copper thickness from 4 oz/ft2 to 20 oz/ft2 is also considered heavy copper PCB, while copper weights above 20 oz/ft2 and up to 200 oz/ft2 are referred to as extreme copper. With an appropriate substrate and thicker plating in the through-hole circuit, the copper weight makes these PCBs a reliable wiring platform. These boards are manufactured through a variety of etching and plating techniques. The goal is always to add copper thickness via plated holes and sidewalls.

Benefits of Heavy Copper PCB:

Compared to conventional printed circuit boards, a PCB with heavy copper traces and/or planes offers several advantages.

  • A Simple & Strong Structure

When integrated into the PCB, high-current circuits allow designers to achieve higher density and reduce the layer count. This also keeps the structure of the PCB relatively strong but uncomplicated.

  • Reduces Failure State

Complex printed circuit boards with high current requirements generate more heat. Copper has high heat-conducting abilities and helps to conduct heat away from vital temperature-sensitive components.

  • Lower Production Costs

Although copper is expensive, rather than using copper cables, using PCBs with heavy copper results in an overall lowering of production costs.

Applications of Heavy Copper Circuit Boards

Heavy Copper PCBs are generally used for high power distribution, heat dissipation, planar transformers, and power converters. Besides, the following are other applications that use heavy copper PCBs:

  • Power supplies for Radar Systems
  • power converters
  • Safety and Signal Systems
  • Welding equipment
  • Protection Relays
  • Power Line Monitors
  • Torque Controls
  • Overload Relays
  • Automotive industry
  • Solar panel manufacturers
  • Nuclear Power Applications
