“Panasonic Corporation announced today that its Industry Company has developed MEGTRON 8[1] Multi-Layer Circuit Board Materials Featuring Low Transmission Loss [2], designed for high-speed communication networking equipment such as routers and switches.
The worldwide deployment of the fifth-generation mobile communication system (5G) is fostering the trend of continuous social change toward the Internet of Everything (IoE) where all things will be connected through the Internet. The number of connected terminals and the volume of communication data is expected to increase significantly as IoE technology continues to evolve. In accordance with this trend, solutions for high-speed signal processing and increased power consumption have become major technical challenges.
High-speed communication networking equipment, the backbone of IoE technology, will now need to meet 800 GbE[3] (112 Gbps[4], PAM4[5]) targets, which are twice as fast as the current 400 GbE standards. As the electricity flowing through the conductors in printed circuit boards increases in speed and frequency, the transmission loss grows commensurately. This means new, high-performance circuit board materials with reduced transmission loss are required to ensure signal quality.
Panasonic leverages its proprietary resin design expertise and material compounding technologies to deliver both the excellent dielectric properties and the low transmission loss required for high-performance, high-layer-count circuit boards. Panasonic also incorporates both ultra-low dielectric dissipation factor glass cloth and low-profile copper foil[6] into MEGTRON 8.
Using these technologies, Panasonic has developed MEGTRON 8 Multi-Layer Circuit Board Materials featuring the Industry’s Lowest Transmission Loss for this class of circuit board materials, thereby contributing to larger capacity and higher speed data communication. In addition, this product may reduce power consumption through lowering transmission loss.
Panasonic’s new MEGTRON 8 has the following features:
1. Panasonic has used its proprietary resin design and material compounding technologies to achieve the industry’s lowest transmission loss for this class of circuit board materials - an improvement of about 30% compared to Panasonic conventional materials
2. MEGTRON 8 exhibits excellent heat resistance and reliability similar to Panasonic conventional product and is applicable for high-performance, high-layer-count (20+)
MEGTRON7 R-5785(N)
3. MEGTRON 8 has the same manufacturability and processability as Panasonic conventional PCB laminate product and can be manufactured using standard multi-layer circuit board processes.
Suitable applications:
Routers, switches, optical transmission equipment, servers, AI servers, base stations, semiconductor test equipment, probe cards, etc.
Product features:
1. Panasonic has used its proprietary resin design and material compounding technologies to achieve the industry’s lowest transmission loss for this class of circuit board materials - an improvement of about 30% compared to Panasonic conventional materials
Panasonic has achieved the industry’s lowest transmission loss by using its proprietary resin design and material compounding technologies to enable excellent dielectric properties, as well as integrating ultra-low dielectric dissipation factor glass cloth and low-profile copper foil:
contributing to improvement in the signal processing performance of high-speed communication networking equipment. Using circuit board materials with low transmission loss improves current transmission efficiency, thus potentially reducing power lost to heat.
2. MEGTRON 8 exhibits excellent heat resistance and insulation reliability similar to Panasonic conventional product and is applicable for high performance, high-layer-count circuit boards.
The company’s proprietary resin design and material compounding technologies feature both a high glass transition temperature and high thermal decomposition temperature in addition to heat resistance and insulation reliability. These properties ensure excellent reliability in high temperature environments, even for high-layer-count circuit boards with more than 20 layers — such as those used in high-end servers and routers. This contributes to the stable operation of such equipment.
3. MEGTRON 8 has the same manufacturability and processability as Panasonic conventional product and can be manufactured with standard general multi-layer circuit board fabrication processes.
Differing from a fluoropolymer-based circuit board material using polytetrafluoroethylene (PTFE), a resin well known for its low transmission loss, MEGTRON 8 is made of a thermoset resin system. This means MEGTRON 8 has the same manufacturability and processability in standard circuit board processes as conventional materials offer.”
