Rogers RO4350B high-frequency sheet material parameters and electrical characteristics

follow

1、 Rogers RO4350B high-frequency board has the following characteristics:

The dielectric constant (Dk: 3.48/-0.05) of Rogers RO4350B high-frequency board has strict tolerance control and low loss characteristics (Df: 0.0037 10GHz), making it easy to mass produce CAF impedance (ion migration resistance). The processing technology of RO4350B can be the same as standard epoxy resin/glass cloth.

Rogers RO4350B high-frequency board is fully compatible with traditional PCB manufacturing technology and does not require special pre-treatment for through-hole copper plating (PTFE board requires plasma treatment) or other pre-treatment processes. The solder mask process can also be ground. Compared to traditional microwave material laminates, the price is lower, so it is widely used in active devices and high-power RF designs that require a fire rating of UL 94V-0.

Rogers RO4350B high-frequency board material is a proprietary textile glass cloth reinforced ceramic filling material/hydrocarbon composite material, which combines the electrical properties of PTFE/glass cloth materials with the processability of epoxy resin/glass cloth.
