XT2773R7 Silver Sinter Paste, a proprietary formulation specifically developed to deliver a wider range of benefits and performance characteristics compared to high-lead solders. Kyocera s lead-free, pressureless Silver Sinter Paste exhibits excellent thermal and electrical performance, plus strong adhesion to bare copper, making it ideal for high-reliability applications in which heat dissipation is crucial including power semiconductors, automotive modules and high-brightness light emitting diodes (LEDs).
High-power devices such as insulated-gate bipolar transistors (IGBTs), LED power sources and automotive modules have hit a performance ceiling due to the limited thermal dissipation offered by traditional power die attach materials, Kyocera s Silver Sinter Paste is the solution that will help drive technology to the next level by enabling customers to overcome ongoing technical hurdles and maximize package performance.
Based on nano-silver technology, Kyocera s Silver Sinter Paste demonstrates a thermal conductivity of more than 200 W/mK, and excellent die-shear adhesion to bare copper and silver- and gold-plated surfaces. Compared to standard solders and electrically conductive die-attach pastes, Kyocera s Silver Sinter Paste offers more than three times the thermal conductivity. Moreover, through the utilization of a novel resin-dispersion system, the paste shows excellent interface reliability in the most demanding applications.
The semiconductor industry is making every effort to eliminate high-lead solder in its products, where feasible, due to environmental and health concerns. Many semiconductor devices serve essential safety purposes in automotive and industrial applications. Until now, high-lead alloys which offer a high melting point and thermal conductivity were considered necessary to guarantee the required level of reliability. By leveraging the unique properties of nano silver, Kyocera s solution to further enhance semiconductor performance offers a low-temperature, pressureless silver solder option that enhances the performance of high-power semiconductor devices, such as gallium nitride (GaN) and silicon carbide (SiC).
Kyocera s XT2773R7 Silver Sinter Paste is manufactured in Kyocera Chemical Corporation s Kawasaki, Japan factory, and is already in use by customers worldwide. Kyocera s Silver Sinter Paste is now available to U.S. customers in both sample and bulk delivery options.
