The core product number is R-5785 and the prepreg (adhesive film) is R-5680 Panasonic Automotive and Industrial Systems announced on May 28, 2014 that it has developed a low-loss multi-layer substrate material "MEGTRON7" for high-capacity, high-speed transmission applications such as high-end servers, routers, and supercomputers. The product has a relative permittivity of 3.3 (at 1 GHz) and a dielectric loss tangent of 0.001 (at 1 GHz). Compared with the original "MEGTRON6", the transmission loss is reduced by 20%. The new materials ensure the same solder heat resistance and insulation reliability as MEGTRON6 by adopting self-developed resin design and deployment technology. The reflow heat resistance was 10 cycles (260°C, 28 layers), and the insulation reliability was 500 hours (temperature 121°C, humidity 85%, voltage 50V). The glass transition temperature was 210°C and the thermal decomposition temperature was 400°C. Multi-layer circuit boards with more than 30 layers are also excellent in manufacturability and are suitable for use in high-end servers requiring multi-layered substrates. Matsushita Automobile and Industrial Systems Corporation plans to mass produce the material from summer 2014. The company will display the product at "JPCA Show 2014" held at Tokyo Ariake International Convention and Exhibition Center on June 4-6, 2014.
