KYOCERA Brings Low-Temp, High-Thermal-Conductivity Silver Sinter Paste to U.S. Semiconductor Market

By Business Wire News


Kyocera America, Inc., Chemical Sales Division, today announced the U.S. introduction of its environmentally-friendly 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,” said Bob Whisler, president of Kyocera America, Inc. “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 is actively engaged in the development of environmentally friendly products and strives to reduce the use of environmentally-harmful materials and processes in the industries it supports.

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.

Kyocera America, Inc. will be exhibiting at the 2015 IEEE MTT-S International Microwave Symposium (IMS) in Phoenix from May 19-21 in booth #233. Please contact Iris Labadie for more information at 858.614.2592.

About Kyocera

San Diego-based Kyocera America, Inc. provides high-reliability ceramic packages, complex modules, and contract assembly services for numerous electronics markets and applications, with customers in the U.S., Europe, and Asia. It is a wholly-owned subsidiary of Kyocera International, Inc., the North American holding company for Kyocera Corporation.

Kyocera Chemical Corporation, headquartered in Tokyo, joined the Kyocera Group after Kyocera’s 2002 merger with Toshiba Chemical Corporation, founded in 1974. Kyocera Chemical Corporation specializes in organic chemical products, varnishes, resins, adhesives, molding compounds, thermo-setting sealing, and semiconductor assembly materials.

Kyocera Corporation (NYSE:KYO) (TOKYO:6971), the parent and global headquarters of the Kyocera Group, was founded in 1959 as a producer of fine (or “advanced”) ceramics. Kyocera specializes in combining these engineered materials with metals and integrating them with other technologies to produce microelectronic packages and substrates, electronic components, cutting tools, industrial components, solar power generating systems, printers, copiers, and mobile phones. During the year ended March 31, 2015, the company’s net sales totaled 1.53 trillion yen (approx. USD12.7 billion). Kyocera appears on the latest listing of the “Top 100 Global Innovators” by Thomson Reuters, and is ranked #552 on Forbes magazine’s 2015 “Global 2000” listing of the world’s largest publicly traded companies.
