F4BM300 High Frequency PCB DK3.0 0.6mm PTFE substrates 2oz Copper With Immersion Gold
(PCB's are custom-made products, the picture and parameters shown are just for reference)
Brief Introduction
This F4B PCB features a square design with dimensions of 85mm x 85 mm, utilizing a double-sided layout that contains two layers of copper. It is compatible with surface mount components, while through-hole components are not included in this design.
This F4BM300 High Frequency PCB’s layer stackup consists of a top layer made of 70 µm (2 oz) copperstartingwith1ozplating, along with a durable F4BM300 core material that has a thickness of 0.508 mm. The bottom layer also incorporates 70 µm (1 oz) copper with plating, ensuring reliable performance.
The surface finish is Immersion Gold, which enhances solderability and provides excellent protection against corrosion. A black solder mask is applied to the top side of the F4B PTFE substrate PCB, offering both durability and a sleek appearance while safeguarding the underlying circuitry.

F4BM High Frequency Laminates
F4BM series materials are made by scientifically formulating and strictly pressing a combination of fiberglass cloth, polytetrafluoroethylene resin, and polytetrafluoroethylene film. Its electrical performance is improved compared to F4B substrates, mainly due to a wider range of dielectric constants, lower dielectric loss, increased insulation resistance, and improved stability. It can replace similar foreign products.
Features & Benefits
-DK options available: 2.17 to 3.0, customizable DK
-Low loss
-F4BME paired with RTF copper foil, excellent PIM performance
-Diverse sizes, cost-effective
-Radiation resistance, low outgassing
-Commercialized, large-scale production, high cost-effectiveness
Typical Applications
Microwave, RF, radar
Phase shifter, passive components
Power divider, coupler and combiner
Feed network, phased array antenna
Satellite communication, base station antenna
