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.
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.
Double sided circuit boards on RO4350B are available in a variety of thicknesses, such as 10mil, 20mil, 30mil and 60mil. It's used in a variety of typical and non-traditional microwave / radio frequency applications, such as base station antennas, attenuator, power amplifiers, RFID, radar and sensors etc.

The multilayer PCB of RO4350B is mostly four-layer, six-layer and eight-layer, and some are designed as three-layer (false four-layer), five-layer (false six-layer) and so on.
In order to save production cost without reducing signal loss in high frequency environment, FR-4 glass fiber material is mixed with RO4350B in multi-layer circuit board. The high frequency material is used in signal layer and FR-4 glass fiber material is used in other layers.
The basic colour of RO4350B PCB is white.
