Power electronics continue to advance toward higher efficiency, greater power density, and more compact architectures. From industrial motor drives to renewable energy inverters and high-current battery systems, modern equipment demands circuit boards that can withstand extreme electrical and thermal stress. At the core of these high-power platforms is the Heavy Copper PCB, a specialized board...
Energy Storage Systems (ESS)—from large-scale Battery Energy Storage Systems (BESS) to EV battery packs, industrial UPS units, and hybrid inverters—operate under sustained electrical and thermal stress. High charging currents, repeated load cycles, and fast switching from power semiconductors all demand a PCB platform that can withstand extreme conditions without degradation. This is exactly where Heavy...
Industrial power electronics, including motor drives, UPS systems, and high-power converters, demand PCBs capable of handling high current densities while maintaining thermal stability and signal integrity. Heavy copper PCBs, typically ranging from 2 oz to 12 oz copper weight, enable efficient current flow and significantly improve heat dissipation across multilayer stackups. KKPCB specializes in multilayer...
High-power telecom amplifiers in 4G/5G base stations, satellite uplinks, and RF power transmitters operate under extreme currents and elevated temperatures. Maintaining low insertion loss, minimized Joule heating, and stable impedance is critical to achieve high RF efficiency, thermal reliability, and signal integrity. Heavy copper PCB laminates (copper thickness 3–6 oz, Dk ~4.0, low Df @10...
Heavy Copper PCBs: High-Current Solutions for Power Electronics As electronic systems evolve toward higher power density, stronger reliability requirements, and increasingly harsh operating environments, Heavy Copper PCBs have become indispensable across power electronics, automotive systems, industrial control, and energy infrastructure. Unlike standard PCBs—typically manufactured with 1oz–3oz copper—a Heavy Copper PCB is defined as any PCB...
