F4BM is made by scientifically formulating and rigorously pressing glass cloth, semi cured sheet, and PTFE (polytetrafluoroethylene) resin. Its electrical performance has been improved compared to the F4B series, mainly due to a wider range of dielectric constants, lower dielectric loss tangent, increased resistance, and more stable performance.
