FAQ about Thick copper PCB

Are there any design guidelines for thick copper PCBs?
Yes. Due to the increased copper thickness, trace width, spacing, and via plating need to be carefully designed. Our engineering team provides DFM (Design for Manufacturability) support to help you optimize your layout for thick copper requirements.
Can SprintPCB produce multilayer thick copper PCBs?
Yes. SprintPCB supports multilayer thick copper PCBs, combining heavy copper with advanced lamination techniques to ensure signal integrity and thermal management in complex designs.
What are the advantages of thick copper PCBs?
They offer high current-carrying capacity, improved heat dissipation, mechanical strength, and extended product life in demanding environments.
What are the main applications of thick copper PCBs?
Thick copper PCBs are widely used in power supply modules, automotive electronics, renewable energy systems, industrial control, and high-power converters, where high current and efficient heat dissipation are essential.
What is considered a thick copper PCB?
A thick copper PCB typically refers to boards with copper thickness of 2 oz (70μm) or more per layer. SprintPCB can manufacture up to 6 oz copper for heavy-duty applications.
