What is Rogers PCB?

Rogers is a type of high-frequency board produced by Rogers. It is different from the conventional PCB board—epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as the high-frequency material. Rogers has superior dielectric constant and temperature stability. Its dielectric constant thermal expansion coefficient is very consistent with copper foil, which can be used to improve the deficiencies of PTFE substrates. It is very suitable for high-speed electronic design, commercial microwave, and radio frequency applications. Its low water absorption is ideal for high-humidity applications, providing customers in the high-frequency board industry with the highest quality materials and related resources, which fundamentally enhance product quality.

Features of Rogers PCB

The basic difference between Rogers PCB and ordinary PCB states for the high-frequency PCB used in heavy industrial purposes or applications.

The quality outperforms than the general PCB and it is trusted by many people to use in complex and crucial purposes.
The distinctive features that have made it extra-ordinary include:

  • The application where Rogers PCBs can be used for microwave point to point, RF identification tags, automotive radar and sensors, and power amplifiers

  • It is composed with woven glass reinforced hydrocarbon

  • High-resolution electrical performance has close interaction to PTEE

  • A thin layer of conductive materials are used in PCBs to give it strength and power

Comparison between Ordinary and Rogers PCB

The key differences are found at the usage of ordinary and Rogers PCB:

Rogers PCBs are widely used in high-frequency applications whereas ordinary PCBs cannot serve properly in high frequencies

Rogers PCBs are the least in absorbing water compared to the ordinary PCBs

Rogers PCBs can be used in harsh environmental conditions and ideal for use in aerospace and defense ,

but ordinary PCBs are more appropriate to use in low exhausting areas like standard switchboards.

Applications of Rogers PCB

Rogers PCBs are highly effective to use in:

  • Defense

  • Military

  • Wireless

  • Telecommunication

  • Automotive industries
