Products Description
Rogers 4350B is a high performance PCB material with excellent electrical properties, especially in high frequency applications. The material has a dielectric constant (Dk) of 3.48 ± 0.05 and a loss factor (Df) of 0.0037 at 10 GHz, properties that make it low-loss and highly stable in high-frequency signal transmission. The Rogers 4350B’s gold finger PCB refers to the use of gold plating on the edge portion of the PCB to provide better connectivity and abrasion resistance.
Performance Features:
Low Dielectric Loss: The Rogers 4350B’s low loss factor helps reduce losses in high frequency signal transmission.
Stable Dielectric Constant: The dielectric constant varies less over a wide frequency range, helping to maintain stable circuit performance.
Low Coefficient of Thermal Expansion: The Z-axis coefficient of thermal expansion is 32 ppm/°C, which helps improve the dimensional stability of multilayer circuit boards.
High Glass Transition Temperature (Tg): The Rogers 4350B has a Tg value of greater than 280°C, providing excellent heat resistance.
Goldfinger Finish: The Goldfinger PCB finish provides good solderability and oxidation resistance for a wide range of soldering processes.
Application Areas:
High-frequency Communication Equipment: Such as base station antennas and power amplifiers.
Automotive Electronics: Including automotive radar systems and sensors.
Aerospace: In the aerospace field, this PCB can be used for high-performance communication and navigation systems.
Military and Defense: In military communications and electronic warfare systems, the high performance and reliability of this PCB is critical.
Microwave Point-to-Point Connections (P2P): Used in microwave communication systems for point-to-point connection devices.
Processing Precautions:
Drilling: Special attention should be paid to the selection of drill bits and the setting of drilling parameters during drilling to avoid sheet breakage.
Hole Metallization: Special hole treatment techniques may be required, such as plasma treatment or sodium naphthalene activation treatment.
Soldermask Production: Control of soldermask adhesion and blistering may require the use of appropriate pre-treatment methods and strict control of the curing process.
Surface Treatment: Strictly control scratches and damages on the board surface, as these defects will affect the performance and reliability of the circuit.
Testing and Inspection: Testing and inspection of HF boards is more complex and requires the use of specialized equipment and techniques to ensure that the performance of the circuit meets the design requirements.
Storage Conditions: Materials should be stored at less than 50% humidity and less than 23°C to maintain their performance.
Environmental Compliance: Ensure that all materials and processes meet environmental requirements such as UL 94V-0 fire rating.
It can ensure the processing quality and performance of Rogers 4350B Gold Finger PCB to meet the strict requirements of high frequency applications.
