Description
Data Sheet

1. F4BM-1/2 PTFE Laminate Manufacturing & Electrical Performance

F4BM-1/2 is manufactured by laminating woven glass fabric, bond film, polytetrafluoroethylene (PTFE) resin, and PTFE film via scientific formulation and strict laminating processes. As an upgraded product of the F4B series, it boasts superior electrical performance compared with the F4B series, including a wider dielectric constant range, lower dielectric loss tangent, higher insulation resistance, and more stable overall performance—enabling it to replace similar foreign products and adapt to more high-frequency application scenarios.

For more detailed technical parameters and specifications of F4BM, please refer to the professional technical documentation of F4BM series.

2. F4BM PTFE PCB Dimensions

Standard available dimensions (mm): 12''x10''(300x250mm), 14''x15''(350x380mm), 17''x22''(440x550mm), 18''x24''(460x610mm), 20''x20''(500x500mm), 20''x24''(500x600mm), 33''x33''(840x840mm), 24''x36''(610x914mm). Custom dimensions are also available to meet specific customer needs, providing flexible material solutions for diverse project requirements and effectively reducing material waste.

3. Dielectric Constant of F4BM PTFE PCB

Dielectric constant (@ 10GHz): 2.2, 2.55, 2.65, 3.0. These stable dielectric constant values ensure minimal signal delay and loss during high-frequency transmission, laying a solid foundation for the stable operation of F4BM PTFE PCB in high-frequency scenarios. The dielectric constant of F4BM can be precisely adjusted by modifying the ratio of PTFE to woven glass fabric, balancing low loss and dimensional stability.
