Hello Everyone,
Today, we’re going to introduce high frequency PCB built on RO4350B laminates.

RO4350B is a woven glass cloth reinforced hydrocarbon resin ceramic-filled laminate from Rogers Corporation, which has very similar electrical properties to PTFE/fabric glass cloth material and its processability is similar to epoxy resin/glass cloth material.

The Reason for using RO4350B Laminates

1. Superior high frequency performance

RO4350B materials are hydrocarbon ceramic filled laminates, not PTFE which are designed to offer superior high frequency performance.

2. Low dielectric loss

Low loss results in excellent electrical performance and allows applications with high operating frequencies.

3. Stable electrical properties versus frequency

RO4350B material possesses the properties of RF microwave circuits, matching networks and controlled impedance transmission lines.

4. Low thermal coefficient of dielectric constant

This allows the RO4350B to exhibit excellent dimensional stability, a property needed for mixed dielectric multi-layer PCBs constructions and reliable plated through holes.

5. Cost

RO4350B laminates can be fabricated using standard FR-4 processes, do not require speicalized via preparation prcoesses, can be processed by automated handling systems and scrubbing equipment used for copper surface preparation. This properties allow it can be using in volume manufacturing and get competitively priced.

PCB Capability

RO4350B offers double sidedcircuit boards with a range of thicknesses from 10mil to 60mil. These boards are suitable for typical and unconventional applications in microwave and radio frequency domains, including base station antennas, power amplifiers, attenuators, sensors, radar, and RFID systems.

 
The multilayer PCB is created using RO4350B as the core material, with options such as 4-layer board on 6.6mil core, 20mil core, or 2 cores of 10mil. This approach differs from multilayer PCBs made with FR-4. The fixed thickness of the core is crucial to the electrical length of the RF lines on the circuit board.

To balance cost-effectiveness with maintaining signal integrity in high frequency environments, a hybrid PCB is created by incorporating both FR-4 glass fiber material and RO4350B in the multilayer circuit board. The high-frequency material is used in the signal layer, while FR-4 glass fiber material is integrated in the other layers.
