Heavy Copper PCBs are printed circuit boards with 3 or more ounces of finished copper in the inner and/or outer layers.

Heavy Copper PCB General Info

Heavy Copper Board does not have a set of definition per IPC. According to PCB industry, however, peopel generally use this name  to identify a printed circuit board with copper conductors 3 oz/ft2 - 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board.

Heavy copper normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors, and so on.

Design Guide for Heavy Copper PCB

The minimum width and thickness of a heavy copper PCB conductor is determined primarily on the basis of the current carrying capacity required and the maximum permissible conductor temperature rise.

A circuit board trace, depending on its size and manufacturing process, may not be rectangular in shape. Heavy copper conductors can significantly add to the overall board thickness.

Additive (plating) processed are preferred to subtractive (etching) processes but are more expensive).

Typical conductor width/spacing/thickness tolerance is +/-20%, although tighter

tolerance is achievable



Capability of Heavy Copper PCB

Benefits of Heavy Copper PCBs

Elimination of complex wired buss configurations

Increased current carrying capacity

Increased endurance to thermal strains

Optimized use of exotic high temperature materials with lower probability of circuit failure

Ability to incorporate multiple copper weights on the same layer of circuitry (layer count reduction)

Added copper plating in the heat vias (thermal resistance reduction)

Selective areas plated with heavy copper can function as a heat sink or interface to cold plate (built-in heat sinks)

Integration of high-current circuits and control circuits on a single PCB
