What is the specifications of Heavy Copper PCB?

The specifications of Heavy Copper PCB can vary based on specific application requirements and design

considerations. Here are some common specifications:

Copper Thickness: The copper thickness of Heavy Copper PCB is typically greater than standard PCBs. Common copper

thickness ranges from 2 ounces (70μm) to 20 ounces (700μm) or more.

Copper Distribution: Heavy Copper PCBs often utilize a multilayer copper distribution, with copper layers

distributed on both inner and outer layers. Inner copper layers can be enhanced with techniques like copper filling

to improve current-carrying capacity.

Board Thickness: Heavy Copper PCBs can have various board thicknesses depending on specific requirements. Common

standard board thickness ranges from 1.0mm to 3.2mm. For certain applications, the thickness may be greater.

Trace Width/Spacing: The trace width and spacing of Heavy Copper PCB can vary based on design requirements and

manufacturing capabilities. Generally, it can achieve smaller values of trace width/spacing to enable high-density

circuit layouts.

Pad and Hole Sizes: The sizes of pads and holes in Heavy Copper PCB can be determined based on component packages

and assembly processes.

These specifications are subject to customization and can be tailored to meet specific project requirements. It's

important to consult with the manufacturer or PCB designer to determine the appropriate specifications for your

Heavy Copper PCB design.
