Lead-free terminations (typically SnAgCu) have higher melting points (217-227°C vs 183°C for SnPb), requiring higher reflow temperatures but offering better environmental compliance. Tin-lead provides superior solder joint formation and thermal fatigue resistance but is restricted in many applications due to RoHS regulations.
Termination materials directly impact ESR (Equivalent Series Resistance), current carrying capacity, and thermal performance. Silver terminations offer lowest ESR but higher cost, while copper provides good conductivity with better cost-effectiveness. Barrier layers prevent diffusion that could degrade electrical properties over time.
