A Thickness 3mm Copper 3OZ Transformer Plate PCBA is a heavy-duty printed circuit board assembly engineered for high-power, high-frequency applications such as industrial power supplies, electric vehicle (EV) chargers, and renewable energy systems. Built on a 3mm FR4 substrate with 3 oz (105 µm) copper layers, it delivers exceptional current-carrying capacity (up to 20A/mm²) and heat dissipation, critical for transformer and inductor circuits. The multi-layer design (up to 12 layers) supports complex topologies like LLC resonant converters, while ENIG surface finish ensures reliable solder joints and corrosion resistance. Compliant with IPC-2221 and UL 94V-0 standards, this PCBA operates in extreme temperatures (-40°C to +150°C) and integrates thermal vias or metal-core substrates to manage thermal loads. Applications include solar inverters, motor drives, and telecom power systems, where durability and signal integrity are paramount.
