Double Layer 4OZ Thick Copper PCB Blind Buried Via for Industrial Inverter
♦ What is Thick copper PCB?
Thick copper PCB refers to a circuit board formed by bonding a layer of copper foil with a thickness of 2 ounces (oz, about 62.5 microns) or more to FR-4 or other substrates during the printed circuit board (PCB) manufacturing process.
♦ Features of Thick Copper PCB
♦ Applications of Thick Copper PCB
♦ Typical Application Scenarios of Thick Copper PCB
Power conversion equipment: photovoltaic inverters, electric vehicle OBCs and server power supplies use ≥4oz thick copper plates + heat dissipation design to control temperature rise <40℃.
Industrial control: PLC, inverters, etc. use double-layer 3oz thick copper plates + blind holes to achieve compact layout.
New energy field: energy storage busbars and fuel cell boards use ≥5oz thick copper + nickel plating (≥5μm) for corrosion protection.
