Introduction to RO4003C Low Profile Base Material
Rogers RO4003C LoPro laminates utilize proprietary Rogers technology, which allows reverse treated foil to bond to standard RO4003C dielectric. This results in a laminate with low conductor loss, improving insertion loss and signal integrity while preserving all favorable characteristics of the standard RO4003C laminate system. As hydrocarbon ceramic laminates, RO4003C LoPro is designed to deliver superior high-frequency performance and cost-efficient circuit fabrication. It is a low-loss material compatible with standard epoxy/glass (FR-4) manufacturing processes and eliminates the necessity for specialized via preparation (e.g., sodium etch), thereby lowering manufacturing costs.
