In the specialized field of Deep UV (UVC) LED engineering, thermal management is the fundamental bottleneck determining device reliability. Unlike visible LEDs, UVC LEDs have an External Quantum Efficiency (EQE) of only 3% to 5%, meaning over 95% of electrical energy is dissipated as waste heat.
-
The Rth Challenge: High-density SMD packages (3535/6868) require minimized Thermal Resistance (Rth) to prevent junction temperature (T_j) spikes.
-
Material Science: Aluminum Nitride (AlN) ceramic substrates offer conductivity $>170$ W/m·K, far superior to standard MCPCBs.
-
Engineering Solution: Utilizing Eutectic Bonding (AuSn) instead of silver paste eliminates high-resistance interfaces, preserving L70 lifetime in 144-die arrays.
