Heavy copper printed circuit boards are in high demand and are widely used in various electronic industries. The PCBs have become one of the hottest PCBs with a good development prospect in the PCB industry.
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.
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 use copper cables, using PCBs with heavy copper results in an overall lowering of production costs.
