Rogers 4350B sheet is a patented, hydrocarbon resin system/ceramic filler reinforced with woven glass cloth that excels in RF circuit board applications. The following is a specific description of the features and performance of Rogers 4350B sheet:


Excellent Electrical Properties: 

Rogers 4350B sheet has electrical properties very close to those of PTFE/woven glass cloth materials, with low dielectric constant tolerances and low losses to meet the requirements of commercial-grade equipment manufacturers for printed circuit boards.


The sheet's processability is similar to that of epoxy/glass cloth materials, so it can be processed using standard epoxy/glass cloth processes, making it easy to manufacture in high volume.


Rogers 4350B is fully compatible with traditional PCB manufacturing techniques and can be soldermasked directly without special pre-treatment processes, thus increasing productivity.


Rogers 4350B boards are less expensive than traditional microwave material laminates, making them more competitive in the marketplace.

High Thermal Stability: 

Rogers 4350B sheet has high thermal stability and can withstand high temperature environments without significant degradation or deformation. This allows it to excel in high-power, high-temperature RF applications.

Excellent Mechanical Properties: 

The sheet has good mechanical strength and toughness and is able to withstand mechanical stresses and impacts, minimizing the potential for damage or fracture during fabrication and installation.

Good Dimensional Stability: 

Rogers 4350B boards have high dimensional stability and are less prone to significant dimensional changes due to environmental factors (e.g. humidity, temperature changes). This is critical to ensuring the board's accuracy and consistency.

Outstanding Chemical Resistance: 

The board is highly resistant to a wide range of chemicals and is less susceptible to corrosion or damage, which increases the life and reliability of the board.

Easy Processing and Manufacturing: 

Rogers 4350B boards are easy to process and can be manufactured using traditional PCB manufacturing processes, including drilling, cutting, and soldering. This makes the production process simpler, more efficient and reduces manufacturing costs.

Stable Electrical Characteristics: 

The Rogers 4350B sheet maintains stable electrical characteristics across a wide range of frequencies, which allows it to excel in high frequency applications.

Low Dielectric Constant Fluctuation with Temperature: 

The sheet's low fluctuation in dielectric constant with temperature ensures board stability and reliability.

Low Z-axis Coefficient of Thermal Expansion: 

Rogers 4350B sheet has a low Z-axis coefficient of thermal expansion, which helps to minimize board deformation during temperature changes and improves board stability.

CAF Impedance: 

The sheet has CAF impedance (resistance to ionic migration), which prevents board failure and damage.

Overall, Rogers 4350B sheet offers excellent characteristics and performance in RF circuit board applications, and is capable of meeting the requirements of a wide range of complex and demanding applications.
