24GHz radar detection system mainly supports short-range detection (SRR), high frequency circuit board and high wavelength. Applicable boards: RO4835, RO4350B, RO4003C . Among them, RO4350B nitride ceramic laminate and RO4835 nitride ceramic laminate are highly recommended. These two series belong to the cost-effective series for people’s daily use.
RO4000 hydrocarbon ceramic laminates are designed to offer superior high frequency PCB performance and low cost circuit fabrication. The result is a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes offered at competitive prices.
Prolonged exposure in an oxidative environment may cause changes to the dielectric properties of hydrocarbon based materials. The rate of change increases at higher temperatures and is highly dependent on the circuit design.
These guidelines were developed to provide fabricators basic information on processing double-sided and multi-layered printed wiring boards (PWB’s) using RO4003C™, RO4350B™ and RO4835™ laminates. Please refer to RO4400™ bondply processing guidelines for additional information on inner-layer preparation and multi-layer bonding.
