A thick copper PCB, or heavy copper PCB, is a printed circuit board where the copper foil has greater weight or thickness than standard copper foils, which usually range between 3 oz/ft²to 10 oz/ft² or even more.
The primary advantages are increased current capacity, heat dissipation improvement, mechanical resilience enhancement while facilitating electroplating adhesion in surface treatment processes.
While thick copper PCBs are primarily designed for power applications, they can be used for high-frequency applications with careful design considerations, such as controlling impedance and minimizing signal losses.
Yes, specific project requirements could be accommodated with custom specifications and designs at UnityPCB.
Yes, thick copper circuit boards are typically more expensive than standard PCBs due to the increased material costs and specialized manufacturing processes required.
Yes, UnityPCB offers prototyping to customers in order to approve their specifics before moving to mass production.
