Megtron 8 PCB Laminate Materials

Megtron 8 PCB laminate is a cutting-edge material that has gained significant attention in the electronics industry. With its exceptional electrical properties and performance characteristics, Megtron 8 is revolutionizing the design and manufacturing of printed circuit boards (PCBs).

Megtron 8 PCB laminate, a recent addition to Panasonic’s product lineup, offers a multilayer PCB solution that significantly enhances communication networking capabilities, particularly in high-speed applications for switches and routers.

If you are contemplating whether to adopt Megtron 8 PCB material, this article will provide you with insights into its benefits and how it can improve your product offerings.

Overwiew of Megtron8 PCB Laminate Material

Panasonic recently introduced a new material featuring a multilayer PCB that enhances and ensures high-speed communication networking for switches and routers.

As the backbone of internet technology, high-speed communication equipment needs to meet increasingly demanding targets, such as 12 Gbps or 800 GbE with PAM4 modulation. These targets represent twice the speed of the current 400 GbE standards. However, this poses a challenge for printed circuit boards as they need to accommodate higher speeds and frequencies to improve data transmission.

Panasonic has addressed this challenge by combining a resin design with a glass cloth that has ultra-low dielectric dissipation, instead of using fluoropolymer-based materials for the printed circuit board. Additionally, the copper foil used in this material has a low profile, which enhances its dielectric properties and minimizes transmission loss. This is crucial for achieving higher performance and accommodating the anticipated higher layer count in future PCB manufacturing lines.

The Megtron 8 PCB material significantly reduces transmission loss for this type of circuit board, offering up to a 30% improvement compared to the least available Panasonic Megtron 7 R-5785 laminate materials at a frequency of 286 GHz.

The thermoset resin materials used in Megtron 8 exhibit heat reliability and resistance similar to the previous generation of Panasonic laminates, ensuring consistent processability and manufacturability. It can be readily manufactured using standard circuitry processes.
