Rogers RO4350B PCB material specification

Rogers RO4350B is the most popular radio frequency PCB material.Rogers RO4350B is a hydrocarbon / ceramic laminate with a dielectric constant of 3.48. It meets the requirements of commercial equipment manufacturers for printed circuit boards.


Rogers RO4350B is a patented hydrocarbon resin system / ceramic filler reinforced by woven glass cloth. Its electrical properties are very close to PTFE / woven glass cloth material, and its machinability is similar to that of epoxy resin / glass cloth material.


Rogers RO4350B can use the standard epoxy / glass cloth processing technology, while providing strictly controlled permittivity and loss at a fraction of the price of traditional microwave materials. There is no need for special through-hole pretreatment or operation procedures like PTFE based microwave materials.
