MEGTRON 7

Ultra-low Loss, Highly Heat Resistant Circuit Board Materials.

LaminateR-5785(N)/Prepreg R-5680(N)

The ultra-low dielectric constant (Dk) and dissipation factor (Df) make MEGTRON 7 ideal for high speed and large data volumes associated with servers and routers required for 5G.

The MEGTRON 7 family, including MEGTRON 7(N), MEGTRON 7(GE) and MEGTRON 7(GN), is High Density Interconnect (HDI) technology compatible with very high layer count and large format printed Circuit Board (PCB) layouts.
