Engineering Reasoning
15-85°C baseplate temperature
105°C baseplate temperature sustained for 30 minutes
Design Rationale: Thermal interface material degradation above glass transition temperature (Tg=110°C for silicone-based TIMs), reducing thermal conductivity from 3.5 W/m·K to <0.5 W/m·K
Risk Mitigation (FMEA)
Trigger Thermal cycling stress (ΔT=60°C, 1000 cycles)
Mode: Solder joint fatigue cracking at LED driver attachment points
Strategy: Copper-core solder joints with 0.3mm standoff height and corner fillets
Trigger Aluminum fin corrosion in chloride environments (>500ppm Cl⁻)
Mode: Fin efficiency reduction from 85% to <40% due to oxide layer buildup
Strategy: Anodized aluminum fins with 25μm coating thickness and hydrophobic surface treatment
