Thick/Heavy Copper PCB

Thick Copper PCB Difinition and Thickness

There is no exact definition of thick copper in the PCB industry. Generally, the copper thickness ≥ 2oz is defined as Heavy copper PCB. Heavy copper PCB is mainly used in high-current electronic products. High-current electronic products are generally high-power or high-voltage PCBs. They are mostly used in automotive electronics, communication equipment, aerospace, planar transformers, and secondary power modules.

Our thickest copper PCB can make 6 ounces. However, considering the side eclipse factor, copper thickness of more than 3 ounces should pay special attention to the line width of the inner layer.

Inner 3 oz copper pcb: line width 6/7 mil outer 3 ounces: line width 8/12 mil

Inner layer 4 oz copper pcb: line width line spacing 8/11 mil outer layer 3 ounces: line width line spacing 9/15 mil

Inner 5 oz copper pcb: line width 10/16 mil outer 3 ounces: line width 11/16 mil

Inner 6 oz copper pcb: line width line spacing 12/18 mil outer layer 3 ounces: line width line spacing 14/18 mil

Heavy Copper PCB Production Difficulties

When the electronic device need high power or current through, Then we need consider heave copper to control the thermal on PCB, Thermal management is more important than ever today as electronics are used in demanding environments and Operative at higher currents. Heavy copper PCBs (copper conductors 5 oz/ft2 – 19 oz/ft2 in inner And/or outer layers; sometimes defined as more than 4 oz per square foot (ft2)) can help conduct heat away from components so failure is greatly reduced. PCB manufacturers create durable wiring platforms with heavy copper. And boards may be manufactured in a smaller footprint as they can contain multiple weights of copper on the same circuit layers.

The Benefits of Heavy Copper PCBs include: Reduction of Thermal Strain
