Heavy Copper PCB for Large Current Power Circuits

Heavy Copper PCB features extra-thick copper layers (over 3oz), specially developed for large-current transmission and distinguished from conventional thin-copper PCBs. Thick copper traces deliver strong current-carrying capacity and low line impedance, preventing overheating and burnout under high-current operation.

Key Characteristics

We adopt professional thick-copper etching, deep-hole heavy plating and copper thickness uniformity control technologies to solve common defects in thick-copper processing. Rooted in niche sectors including industrial power control, EV chargers and power distribution equipment, it is a dedicated board for power electronics. We concentrate on polishing heavy-copper craftsmanship rather than general PCB production. Custom copper thickness and routing schemes are provided for different current standards, ensuring safe and stable operation under long-term high-load and large-current working environments.
