PCB Blog - RT duroid substrate

The RT/duroid substrates are easy to cut, shear, and machine into shapes. They are resistant to all solvents and reagents, whether hot or cold. 8 for RT/duroid μ M~70 μ Copper electrodeposition of m.

Comparison of RT Duroid Substrate with Other Substrates

1) Rogers RT/duroid 5880 provides a beneficial combination of electrical and mechanical characteristics. The Rogers RT/duroid substrate is made of polytetrafluoroethylene glass fiber reinforced material. These microfibers are randomly distributed within the material, providing maximum strength enhancement for circuit application and production processes.

2) These high-frequency materials have the lowest dielectric constant of their kind, and their extremely low dielectric loss makes them very suitable for high-frequency and broadband applications that require minimizing dispersion and loss. In addition, the RT/duroid substrate has extremely low moisture absorption, making it an ideal choice for applications in high-humidity environments.

Characteristics of RT Duriod substrate

1) The RT Duroid substrate is easily cut into the desired shape and can resist the erosion of all solutions and reagents used during the etching and plating process. RT Duroid 5870 and 5880 laminates have the lowest dielectric loss, low moisture absorption, isotropy, and minimal frequency-dependent electrical performance among reinforced polytetrafluoroethylene materials.

2) Ultra-low loss, low moisture absorption, stable dielectric constant with frequency variation, low gas release, suitable for aviation applications.

Common RT duroid substrates

1. RT Duroid 5870
