High-reliability, lead-free die-attach process
Silver sintering (also known as Low-Temperature Joining Technique, LTJT) is a lead-free die-attach process that uses nano- or micro-scale silver particles to form a solid-state diffusion bond at 200–300 °C. The resulting sintered silver layer combines electrical and thermal performance close to bulk silver with a melting point of 961 °C, enabling lower thermal resistance, higher temperature tolerance and longer thermal-cycling life than conventional tin-based solder in SiC/GaN power modules. Our automated silver sintering line integrates key steps such as silver paste/film printing, die attach, low-temperature sintering, in-line inspection and MES data traceability, serving high-reliability packaging scenarios including SiC power modules, IGBT modules, EV traction inverters, PV inverters, charging piles and 5G/radar systems.
Note: Values above are typical process reference indicators; final parameters should be evaluated based on chip size, substrate material and process window.
