Energy Equipment PCB FAQ
Insights into extreme heavy copper, heat management, and power electronics design.
What is the maximum copper thickness you can reliably produce?
We routinely manufacture boards with 3oz, 6oz, and 10oz copper. For specialized high-current applications, we can go up to 12oz. This allows for massive power distribution within the PCB layers, often eliminating the need for external busbars.
How do you ensure solderability on such thick copper traces?
Soldering heavy copper requires specialized profiling. We use advanced OSP or ENIG finishes to ensure excellent wetting, and our engineers can consult on selective wave soldering parameters during your assembly phase to manage the high thermal mass.
Can you implement high-voltage isolation slots (Creepage/Clearance)?
Yes. We provide precision air-gap slots, routing through core materials, and specialized conformal coating support to ensure your board meets international safety standards for creepage and clearance in high-voltage DC environments.
What is "Copper Coin" technology and how does it help energy PCBs?
A "Copper Coin" is a solid piece of copper embedded directly into the PCB under high-power components (like MOSFETs or IGBTs). It provides a direct, high-conductivity thermal path to a bottom-side heat sink, offering up to 20x better cooling than standard thermal vias.
