TMM4 High Performance High Frequency Microwave Laminate

TMM4 is a high-performance high-frequency microwave laminate produced by Rogers. This material is a unique ceramic, hydrocarbon, and thermosetting polymer composite material that stands out in high-frequency applications due to its unique electrical and mechanical properties.

Material composition and characteristics:
The core characteristics of TMM4 lie in its stable dielectric constant (Dk) and low loss factor (Df). At a frequency of 10GHz, its dielectric constant (Dk) remains stable within the range of 4.50 ± 0.045, while the loss factor (Df) is only 0.0020. This stable electrical performance enables TMM4 to maintain efficient and accurate signal transmission in high-frequency applications.
In addition, TMM4 also has an extremely low dielectric constant thermal stability coefficient (TCDk 15ppm/° K), which means that its electrical performance can remain stable under temperature changes. Meanwhile, the thermal expansion coefficient of TMM4 is comparable to that of copper, which enables high reliability and stability in applications such as electroplating through holes.

Processing and application:
The high-frequency board of TMM4 not only has excellent electrical performance, but also excellent mechanical stability. This material has an extremely low etching shrinkage value and can resist the influence of etchants and solvents during the printing circuit manufacturing process. Therefore, all common PCB processes can be applied to TMM4 materials.
Due to its stable electrical and mechanical properties, TMM4 is very suitable for high reliability electroplating through hole ribbon and microstrip line applications. TMM4 can perform excellently in fields such as wireless communication, radar systems, and high-speed digital communication.

Environmental Protection and Sustainability:
It is worth mentioning that TMM4 material meets environmental standards during production and use. Its manufacturing process strictly controls the use of harmful substances and has passed relevant environmental certifications. Meanwhile, due to its excellent performance and stability, TMM4 material can reduce energy consumption and waste generation during use, contributing to sustainable development.
