TMM10i High Frequency Microwave Laminate

TMM10i is a high-frequency microwave laminate produced by Rogers and is a product in the TMM series.
1, Material characteristics
TMM10i is a ceramic, hydrocarbon, and thermosetting polymer composite material with stable electrical and mechanical properties. This material combines the many advantages of ceramics and traditional PTFE microwave circuit laminates, making it excellent in high-frequency applications. Its stable dielectric constant (Dk: 9.80+/-0.245) and low loss factor (Df: 0.0020 at 10GHz) ensure the efficiency and accuracy of signal transmission. In addition, TMM10i also has a very low dielectric constant thermal stability coefficient (TCDk-43ppm/° K) and a thermal expansion coefficient equivalent to copper, which ensure stability and reliability in high reliability electroplating through-hole applications.
2, Processing advantages
Another significant advantage of TMM10i is its convenience in processing. Compared to aluminum oxide substrates, TMM10i laminates can provide larger specifications of copper coating and use standard PCB substrate processing procedures, which gives them significant processing advantages. Before chemical electroplating, TMM10i does not require sodium naphthalene treatment, further simplifying the processing flow. In addition, the TMM10i high-frequency board has an extremely low etching shrinkage value, which can resist the influence of etchants and solvents in the printed circuit manufacturing process. Therefore, all commonly used PCB processes can be used to process TMM10i thermosetting microwave materials.
3, Application scenarios
TMM10i is suitable for various high reliability electroplating through-hole ribbon and microstrip line applications. Due to its stable electrical and mechanical performance, TMM10i is an ideal choice for high reliability applications. For example, in fields such as wireless communication, radar systems, and high-speed digital communication, TMM10i is widely used to manufacture key RF devices such as base station antennas, filters, power dividers, antenna covers, and feeders. In these applications, the high-performance electrical characteristics and excellent mechanical performance of TMM10i have been fully utilized, ensuring the stability and reliability of the system.
4, Environmental certification
TMM10i has also passed RoHS certification, and its products contain extremely low levels of harmful substances such as lead, mercury, and cadmium, making them extremely environmentally friendly. This enables TMM10i to meet both high-performance requirements and environmental standards, making it an excellent representative of sustainable development.
In summary, TMM10i is a high-frequency microwave laminated board with excellent electrical and mechanical properties, convenient processing, wide application scenarios, and environmental certification. In high-frequency applications, TMM10i exhibits excellent performance and stability, becoming the preferred material for many engineers and technicians.
