Megtron6 12-Layer 2.12mm High Speed PCB for 5G and Data Center Applications
1. Introduction of High Speed, Low Loss Multi-layer Materials - Megtron6 (M6) R-5775
The Panasonic M6 laminate is a type of multilayer copper-clad laminate (CCL) specifically designed for high-frequency, high-speed, and high-reliability electronic devices. It is applicable to fields such as 5G communication, millimeter-wave radar, high-speed servers, and high-performance computing (HPC). Its core advantages lie in low dielectric loss (Df), stable dielectric constant (Dk), and excellent thermal reliability, enabling it to meet the stringent requirements of high-frequency signal transmission.
