Thermal Runaway & Board Delamination Under Massive Electrical Currents
High-power BMS energy storage, solar inverters, and motor drives running continuous 100A-200A+ currents generate extreme localized heat. Standard FR4 substrates and thin copper quickly experience resin carbonization, trace blistering, and catastrophic open-circuit burnouts.
We implement 4oz to 10oz heavy copper fabrication with proprietary double-print resin-filled sidewalls, High-TG 170/180+ heat-resistant substrates, and CNC deep creepage slots for high-voltage isolation, ensuring stable thermal transfer under 200A+ continuous loads.
