About Heavy Copper PCB

A heavy copper PCB is a board that uses up to 20 ounces of thick, heavy-duty copper. This type of circuit undergoes special etching and plating methods like differential etching and step plating. You can also call it a “thick” or “heavy” Copper PCB (copper weights range from 4 oz/ft2 to 20 oz/ft2).

Copper is a great conductor for electricity, which means that it can handle high-current/high-power circuits and control circuits on the same board.

And it’s possible to integrate control circuits and high-power circuits on the same board. Plus, it comes with different perks like cost-effectiveness (long-term), low impedance power distribution, etc.


Heavy Copper PCB Advantages

Heavy copper PCB comes with numerous benefits, contributing to the high demand for this material in the electric industry. With the heavy presence of copper on a printed circuit board, the following are the benefits you will enjoy.


ü Regardless of the cost of heavy copper PCB, you will get to enjoy reduced production costs compared to using copper cables once you acquire it.

ü Heavy copper printed boards offer higher heat conductivity, which help to keep temperature-sensitive parts from heating up by conducting the heat away.

ü The PCB structure is relatively strong, although the layer count is limited. This makes the PCB very simple and uncomplicated.

ü There are no complex wire configurations.

ü PCB comes with exotic materials used to enhance its mechanical features.

ü Heavy copper printed boards come with improved thermal endurance and resistance.

ü They carry high currents easily without any complications.

ü Heavy copper PCBs are made from combining various copper weights in one PCB to make a manageable, compact size.


Applications of Heavy Copper PCBs

Demand for heavy copper-clad circuits in automotive, computer, industrial controls, and military is growing very fast. More than 80% of the existing PCB manufacturers are limited or not capable of producing reliable heavy copper printed circuit boards.
