Descripción general
Rogers RO4835 substrate is a hydrocarbon ceramic laminate, an oxidation resistant high frequency material for applications requiring greater stability at elevated temperatures. It is more resistant to oxidation than other hydrocarbon-based materials. RO4835 laminates are designed to provide excellent high frequency performance and low cost circuit fabrication. Además, the electrical and mechanical properties of the RO4835 material are nearly identical to the RO4350B laminate that customers have used successfully for many years.
Oxidation Effects on Thermoset Laminates
Oxidation affects all thermoset laminates over time and temperature. A la larga, oxidation causes a small increase in the dielectric constant and dissipation factor of the circuit substrate.
