SAphire™

Copper is emerging as a promising material for next-generation electronic joining, offering strong electrical and thermal performance, high-temperature reliability, and cost advantages. However, conventional copper sintering still faces challenges in manufacturing maturity, limiting its broader adoption.

Built on Elephantech’s proprietary Self-Assembling Copper Nanoparticle technology, SAphire™ is engineered to overcome these conventional limitations of copper. By combining the inherent advantages of copper with enhanced processability and application-specific performance, the SAphire™ family of sintering copper nanopastes enables bonding, filling, and interconnection for increasingly powerful and complex electronic systems.
