Product Overview

High-temperature solder pastes are typically used for the die-attach of semiconductor dies in discrete components. They are designed to withstand melting temperatures above 260°C, ensuring they do not re-melt during the PCBA reflow process.

Quality Assured

By adhering to stringent standards like AEC-Q101 for automotive reliability, our products and manufacturing processes ensure exceptional quality, joint integrity, and long-term performance.

Wide Selection of Alloys

We offer high-Pb, high-Pb low alpha, and Pb-free options, including gold-tin and our patented Durafuse® HT alloy technology.

Compatible with Various Flux Vehicles

Whether for printing or dispensing, easy-to-clean or ultra-low residue, our range of flux is designed to optimize performance and meet the specific demands of your applications.

No Re-Melting at PCBA Peak Reflow Temperatures

Common Pb-based alloys melt between 295°C and 312°C, high-temperature Pb-free alloys around 340°C, and gold-tin paste approximately 280°C. These melting points ensure the solder remains intact during the PCBA reflow process.
