The PCB material used by teflon PCB. F4BM is laminated by glass woven cloth, adhesive film, Teflon resin and polytetrafluoroethylene film, in accordance with scientific formula and strict

technological process. This product has certain advantages over the F4B series in electrical performance (a wider range of dielectric constant, lower dielectric loss tangent increased resistance, and

more stable performance).

Teflon PCB is widely used to replace ordinary FR4 board because of its excellent characteristics such as good weather resistance. high insulation, high lubrication, non adhesion and non toxicity.

However, compared with ordinary FR4 board, Teflon PCB board is the smallest surface tension in solid materials, does not adhere to any substances, and has very small mechanical properties.I

friction coeffcient is only 1 / 5 of that of polyethylene, This is an important feature of perfluorocarbon surface. In addition, due to the low intermolecular force of fluorine carbon chain, Teflon is notsticky, so it is not easy to adhere to the surface of the substrate in the production process of Teflon PCB.
