Frequently Asked Questions

A heavy copper PCB, or a thick copper PCB, refers to a PCB that has copper thickness greater than 3oz (105μm) per square foot, which is intended to handle high current flows while providing better heat management.

Yes, MOKOPCB holds the capability to manufacture PCBs featuring varied copper weights ascorss different layers. For instance, we can make standard 1oz copper thickness in inner layers and 3oz or more in outer layers.

In a heavy copper PCB design, expanded trace widths and proper heat management system are necessary. Additionally, the trace spacing should be designed larger so as to prevent short circuit.

Of course, we provide one-stop heavy copper circuit boards solutions, from PCB fabrication, component sourcing, to assembly, and testing.

As a general rule, we can deliver heavy copper PCBs within 7 to 15 business days, depending on complexity of the design, the quantity ordered, and the available manufacturing capacity.

Yes, we do offer prototyping service with fast turnaround time so customers can verify their designs before going into mass production.
