F4B PCB manufacturers

F4B PCB manufacturers F4BM material is converted into a polymer compound called "plastic king," which is short for PTFE. Excellent chemical stability, corrosion resistance, sealing, high lubrication and non-viscosity, electrical insulation, and good aging resistance are all characteristics of this material. It can be transformed into PTFE tube, F4BM Antenna PCB锛宺od, belt, plate, film, and other materials while being used as engineering plastic. It is typically used in high performance requirements for corrosion-resistant pipes, containers, pumps, valves, radar, high-frequency communication equipment, and radio equipment. F4BM and F4BME have the same dielectric layer, but the copper foil used together is different: F4BM and ED copper foil are suitable for applications without PIM indicators; F4BME with reverse RTF copper foil has excellent PIM index, more accurate line control and lower conductor loss. F4BM and F4BME precisely adjust the dielectric constant by adjusting the ratio between polytetrafluoroethylene and glass fiber cloth, which not only achieves low loss, but also enhances the dimensional stability of the material; The higher the dielectric constant is, the higher the proportion of glass fiber is, so the dimensional stability is better, the coefficient of thermal expansion is lower, the temperature fluctuation is better, and the dielectric loss is increased. At F4BM Antenna , the dielectric constant of PTFE materials is as low as 3.5 or below, which keeps strong signal during transmission across PCB, making them ideal for overcoming the high speed limitation of FR-4 on cost performance.
