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. The dielectric constant is stable over a broad frequency range (Chart DK vs. frequency).


4. Low thermal coefficient of dielectric constant
The temperature coefficient of dielectric constant is among the lowest of any circuit board material (see Chart DK vs. Temperature), 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.


Our PCB Capability(RO4350B)
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.

Multilayer PCB
The multilayer PCB is made on core of RO4350B, such as 4-layer board on 6.6mil core and 20mil core, 4-layer board on 2 cores of 10mil. This is different from multilayer PCB on FR-4. The core has fixed thickness which is very important to the electrical length of RF lines on the circuit board.


Hybrid PCB
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.

We specialize in provide you with prototype, small batches and mass production service.
