RO4350B vs RO4003C

The RO4350B LoPro PCB circuit board adopts Rogers' proprietary technology, which allows reverse processing of foil materials combined with standard RO4350B dielectrics. This enables the PCB circuit board to have low conductor loss to improve insertion loss and signal integrity, while maintaining all other desirable properties of the standard RO4350B PCB circuit board system.

The RO4350B ceramic PCB circuit board is designed to provide excellent high-frequency performance and low-cost circuit board manufacturing. The result is a low loss material that can be manufactured using standard epoxy resin/glass (FR-4) technology at a competitive price.

Once the operating frequency increases to 500 megahertz or above, the number of laminated materials typically available for designers to choose from will significantly decrease. The RO4350B material has the performance required by designers of RF microwave circuits, matching networks, and controllable impedance transmission lines. The low dielectric loss makes the RO4350B series materials suitable for many applications where high operating frequencies limit the use of traditional circuit boards (PCBs). The temperature coefficient of dielectric constant is the lowest among all circuit board materials, and the dielectric constant remains stable over a wide frequency range.

This makes it an ideal substrate for broadband applications.

The coefficient of thermal expansion (CTE) of RO4350B material provides several key benefits for circuit designers. The expansion coefficient of RO4350B material is similar to that of copper, which gives the material good dimensional stability, which is a characteristic required for mixed medium multilayer board structures.

The low Z-axis CTE of the RO4350B laminate provides reliable electroplated through-hole quality, even in severe thermal shock applications. The Tg of the RO4350B series material is greater than 280 ° C (536 ° F), so its expansion characteristics remain stable throughout the entire circuit processing temperature range.

Using standard FR-4 circuit board processing technology, the RO4350B series PCB circuit board can be easily made into printed circuit boards. Unlike high-performance materials based on polytetrafluoroethylene, the RO4350B series PCB circuit board does not require special preparation processes such as sodium etching. This material is a hard thermosetting PCB circuit board that can be processed through automatic processing systems and scrubbing equipment used for copper surface treatment.
