Low dielectric constant & low dielectric loss tangent printed circuit board materials
It is a printed circuit board material for high-capacity and high-speed communication devices such as base station antennas and high-speed servers and routers.
With the spread of smartphones and tablet devices, the equipment that makes up broadband systems is required to process large amounts of data at high speeds. Additionally, to enhance "connectivity" and expand coverage areas, the installation and upgrading of base stations are being advanced. In response to this, Rishou Industry has prepared printed circuit board materials that have a fast signal propagation speed (low dielectric constant) and a function to minimize transmission loss (low dielectric loss tangent).
basic information
At Richang Industrial, we offer glass cloth-based PPE resin (polyphenylene ether) copper-clad laminates as materials for low dielectric constant and low dielectric loss tangent printed circuit boards. We also have a type that further enhances transmission characteristics by applying VLP (Very Low Profile) copper foil to the surface of this PPE material. Additionally, we offer a halogen-free glass epoxy type.
