Rogers RO4350B DK3.48 High Frequency Printed Circuit Board with 10mil, 20mil, 30mil and 60mil thick Coating with Immersion Gold

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.
