Rogers PCB are high frequency boards that are manufactured using materials sourced exclusively from Rogers. Unlike traditional PCBmade of epoxy resin (FR4), Rogers PCBs use a ceramic substrate as the high frequency material and contain no glass fibers in between. Known for its excellent dielectric constant, low loss angle tangent, and high thermal conductivity, Rogers PCB offer a number of advantages over traditional PCBs. In this blog post, we aim to provide a comprehensive introduction to Rogers PCB, covering their unique features, benefits, applications, and more. Explore the world of Rogers PCB together.
Benefits of Rogers PCB
Rogers PCB are the best choice for many reasons. Rogers materials are preferred for their excellent ability to perform under demanding conditions, as well as for their quality and practicality. This is despite the fact that they are more costly than other materials.

B. Rogers Types and Their Properties：
In this section, we list some of the widely used Rogers materials and briefly describe their properties to help you choose the right material for your PCB project:.
Rogers RO3003 is a popular high-frequency laminate used primarily for RF and microwave applications. This laminate is mainly synthesized from ceramic infused PTFE composition (polytetrafluoroethylene). One of its outstanding features is the remarkable stability of its dielectric constant at different temperatures, which effectively solves the problem of fluctuating dielectric constant commonly found in PTFE glass materials at room temperature.
This 4003 laminate utilizes 1080 and 1674 glass fabrics arranged in an electrically laminated fashion. A noteworthy aspect of 4003C is its electrical properties, which are very similar to those of PTFE/woven glass fabric materials, while its processing is similar to that of epoxy/glass fabric materials. It can be easily cleaned with a conventional nylon brush. The main advantages of RO4003C are its minimal loss characteristics and the two types of glass cloth.
Rogers 4350 is a high performance material for PCB signaling, consisting of glass fibers reinforced with a hydrocarbon resin/ceramic filler instead of PTFE. It offers cost savings compared to conventional microwave laminates because it does not require special THT through-hole processing. The material has a stable dielectric constant over a wide frequency range and a low temperature coefficient, making it an ideal substrate for broadband applications.
Thermoset laminates called RO4830 can be manufactured using standard FR4 technology. This laminate has electrical characteristics that are very close to standard values, resulting in excellent reflectivity and apparent axial gain performance. It is particularly suitable for millimeter-wave applications where cost-effectiveness is a priority, such as automotive radar sensors operating at 76-81 GHz.
RO4835 is a specialized circuit board material developed by Rogers, which is designed for multilayers with inner layer designs. The material is a thermoset pair that effectively mitigates the increase in dielectric constant and dissipation factor caused by oxidized wiring. Compared to traditional thermoset plastics, RO4835T has excellent oxidation resistance, ten times more resistant.
Rogers 5880 high-frequency laminate is a blend of PTFE composites and microfiber. It has extremely low moisture absorption, low outgassing, and low electrical losses. In addition, Rogers RT/duroid dielectric constant 5880 laminates are very stable over a wide frequency range, making them ideal for high frequency and broadband applications.
