Kyocera Brings Low-Temperature, High-Thermal-Conductivity Silver Sinter Paste to the European Market

The innovative paste has the ideal preconditions for high-reliability applications in automotive modules, power modules or in the semiconductor industry and other fields, whose effective operation depends in heat dissipation

Kyoto / Neuss - The Kyocera Corporation launches the innovative environmentally friendly XT2773R7 Silver Sinter Paste in Europe – 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 as well as an extremely strong adhesion to bare copper. These characteristics make this new paste ideal for high-reliability applications in which heat dissipation is crucial, such as power semiconductors, automotive modules and high-brightness light emitting diodes (LEDs).

Based on the nano-silver technology, Kyocera’s Silver Sinter Paste demonstrates a thermal conductivity of more than 200 W/mK and an excellent die-shear adhesion to bare copper, 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 is actively engaged in the development of environmentally friendly products and strives to reduce the use of environmentally harmful materials and processes as much as possible in the industries it supports.
