With the development of society, there is a great demand for heavy copper PCB. Now heavy copper PCBs have been widely used in various electronic industries. In general, heavy copper technology can realize complicated switches in limited space combining the circuitry for high current levels, as well as is good for heat dissipation. Multilayer and double-sided are the most common designs we know. What’s more, thick copper PCB technology makes it possible to combine great layout structures on the external layers and heavy coppers layers in the internal layers.

The definition of heavy copper PCB

Heavy copper PCB is also known as thick copper PCB, in which there are 3 ounces (oz) of copper or more on the internal and external layers of a printed circuit board. The circuit board with a copper thickness of more than 4 oz per square foot (ft2) is also categorized as a heavy copper PCB. Extreme copper means 20 oz per ft2 to 200 oz per ft2. 

The reason why heavy copper PCB is the reliable wiring platform is that the thicker plating in the through-holes circuits and an appropriate substrate combined with copper weight. Heavy copper conductors can improve the whole PCB thickness considerably, so it needs to take the copper thickness into consideration as PCB design. The width and thickness of thick copper determine the current-carrying capability.

The benefits of heavy copper PCB

The main benefit of heavy copper PCB is the capability to support frequency to excessive current, elevated temperatures and recurring thermal cycling, which can do harm to aregular circuit board in seconds. What’s more, there is a great demand for heavy copper PCBs in the computer, automotive, military, and industrial controls.

In additions, the heavy copper PCB board is also used in other purposes:

In addition, there are some other benefits of heavy copper PCB as follows:

1. Compact product size because of several copper weights on the same layer of circuitry;

2. Onboard high-power-density planar transformers;

3. Heavy copper-plated vias pass the elevated current through the PCB and are good for transferring the heat to an outer heat sink.
