Rogers PCB

Rogers PCB are high frequency boards that are manufactured using materials sourced exclusively from Rogers. Unlike traditional PCB made 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.

Rogers high frequency material application areas and plate type characteristics, high frequency board is a special copper-clad plate with high frequency microwave substrate, also called high frequency microwave printed circuit boards, further processing can be manufactured into a high frequency PCB board.

Rogers High Frequency Material Application Areas:

Rogers as the world's leading supplier of specialty boards, Rogers boards in the global market share of up to 50% or more, in the base station antenna RF field has 20 years of industry experience.

The use of Rogers high frequency materials made into Rogers high frequency board, can be widely used in: widely used in communications equipment, industrial control, smart home, custom power supply, medical machinery and other fields.

Rogers high frequency materials can be divided into 3000 series, 4000 series, 5000 series and so on.

Rogers High Frequency Material Models:

Rogers RO3000 series are PTFE composites containing special ceramic fillers for commercial microwave and RF applications. With a variety of different dielectric constant (Dk) values, all can provide consistent mechanical properties. Laminates with more appropriate Dk can be selected in different monolayers to develop many different multilayer designs without warpage distortion or reliability issues. In addition, the dielectric coefficient remains stable over a wide temperature range.

Rogers RO4000 series HF materials are characterized by: non-PTFE, low loss, low tolerance and excellent HF performance, stable electrical characteristics at different frequencies, low dielectric constant temperature coefficient, low Z-axis thermal expansion coefficient, low in-board expansion coefficient, excellent dimensional stability, and ease of mass production. It can be used in satellite TV LNB, microstrip line, cellular base station antennas and power amplifiers, spread spectrum communication systems, RFID tags and so on.

Rogers RO5000 series are PTFE composites. Characterized by low dielectric constant (Dk) and low loss, they are well suited for high frequency/broadband applications. It maintains consistent electrical characteristics over a wide frequency range, easy to cut, share and process molding, good resistance to solutions and reagents used in the process of etching or plating edges as well as over-holes, very suitable for high humidity environments, very mature material.

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 3003

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.

Rogers 4003C

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

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.

Rogers 4830

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.

Rogers 4835T

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

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.
