Product Specification
F4BM220 High Frequency PCB DK 2.2 PTFE PCB with 3.0mm Thick 1oz Copper and HASL Lead Free
(PCB's are custom-made products, the picture and parameters shown are just for reference)
Hello everybody,
Today we talk about a type of F4BM high frequency circuit board at 3.0mm thick.
F4BM series laminates 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, mainly due to a wider range of dielectric constants, lower dielectric loss, increased insulation resistance, and improved stability. It can replace similar foreign products.
