Durafuse® HT
Designed as an alternative to high-Pb alloys traditionally used for semiconductor die-attach application, Durafuse® HT is a high temperature, Pb-free solder solution. Following the Durafuse® mixed-alloy design, Durafuse® HT has been designed to maintain high die shear strength at high temperature and be safe from re-melting at PCBA reflow peak temperatures of 260°C. Durafuse® HT is the only Pb-free solder option that meets this requirement.

Product Overview
High Shear Strength
Durafuse® HT maintains shear strength >15MPa, even at temperatures around 280°C, outperforming high-Pb solder.
Replacement to High-Pb Solder
Durafuse® HT does not require a special set up when used in traditional processes that cater to Pb-containing solder paste. This reduces the risk of adopting the new materials and the time to market.
Superior to Pb Alloys
Though Pb-free, Durafuse® HT outperforms high Pb-containing materials in thermal conductivity, thermal mechanical strength, and electrical conductivity.
Sustainable
By replacing Pb in applications, Durafuse® HT helps customers achieve sustainability goals and comply with environmental regulations and policies.
