Products Alloys Durafuse® HT

Durafuse® HT

As the standout in the Durafuse® mixed alloy family, Durafuse® HT is a Pb-free solder paste engineered as a direct replacement for traditional high-Pb die-attach solders. Designed for applications that demand re-melting temperatures higher than standard PCBA reflow levels (up to 260°C), this is the only Pb-free solution available on the market that meets this specific requirement.

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.
