Nano Cooling + EMI Shielding = The Lifeline for High-Density Electronics I. Tackling 5G Device Thermal Runaway As 5G base stations hit 800W (Sub-6GHz) and 3200W (mmWave), traditional cooling solutions face three critical challenges: 1. Soaring Heat Density: Chip heat flux up to 200W/cm² (exceeding rocket engine nozzles) 2. Signal Interference Crisis: Metal...
