Low-silver solder paste series supports SMT assembly with reduced material cost exposure while maintaining process compatibility. The system features ~0.1–1.1% Ag content compared to ~3.0% in SAC305, enabling lower silver usage. Designed for compatibility with standard SAC305 reflow profiles, minimizing requalification requirements in existing processes. Supports stable wetting performance and controlled voiding behavior, with reliability validated through thermal cycling and mechanical testing. Intended for cost-sensitive SMT applications requiring consistent process performance and long-term reliability.
