Products Description
FR4 (High Tg) + Rogers TC350 Immersion Gold PCB is a high performance printed circuit board (PCB) using a mixture of FR-4 material and Rogers TC350 material. This PCB combines the cost-effectiveness and good mechanical properties of FR-4 with the excellent electrical characteristics of Rogers TC350, especially low insertion loss and high thermal conductivity in high frequency applications. Below is an overview of its properties, application areas and processing considerations:
Properties of FR4(High TG)+Rogers TC350 High Frequency PCB
Low Dielectric Loss: Rogers TC350 material has a low dielectric loss (Df), which helps to minimize losses in high frequency signal transmission.
High Thermal Conductivity: TC350 provides high thermal conductivity, which aids in thermal management in high power applications.
Stable Dielectric Constant: The dielectric constant (Dk) varies less over a wide frequency range, which helps to maintain stable circuit performance.
Low Coefficient of Thermal Expansion: TC350 has a coefficient of thermal expansion (CTE) similar to that of copper, which helps improve the dimensional stability of multilayer circuit boards.
High Glass Transition Temperature (Tg): The high Tg value of FR-4 materials means better heat resistance and stability in high temperature environments.
Immersion Gold Finish: Provides good solderability and oxidation resistance for a wide range of soldering processes.

Microwave Communications: In microwave point-to-point connections (P2P) and satellite communications, this PCB provides stable performance.
Automotive Electronics: Including automotive radar systems and sensors, especially for applications in the 77 GHz band.
Aerospace: In aerospace, this PCB can be used for high-performance communication and navigation systems.
FR4(High TG)+Rogers TC350 High Frequency PCB Processing Considerations
Material Selection: Make sure to use high quality FR-4 and Rogers TC350 materials.
Drilling: Special attention should be paid to the selection of drill bits and the setting of drilling parameters during the drilling process to avoid board breakage.
Hole Metallization: Special hole treatment techniques such as plasma treatment or sodium naphthalene activation may be required.
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.
Following these precautions during production ensures that the FR4 (High Tg) + Rogers TC350 immersion gold PCBs are processed with the quality and performance needed to meet the stringent requirements of high frequency applications.
