Circuito stampato Teflon F4BM a due strati

 

The PCB material used by teflon PCB, F4BM is laminated by glass woven cloth, pellicola adesiva, 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, elevato isolamento, high lubrication, non adhesion and non toxicity. Tuttavia, 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. Its friction coefficient is only 1 / 5 of that of polyethylene, This is an important feature of perfluorocarbon surface. Inoltre, due to the low intermolecular force of fluorine carbon chain, Teflon is not sticky, so it is not easy to adhere to the surface of the substrate in the production process of Teflon PCB.

RF/Microwave Teflon PCB application

Teflon PCB with radio frequency(PCB RF) sono una tecnica sempre più utilizzata nell'industria dei PCB.

–PCB RF ad alta frequenza con lavori di cui sopra 100 MHz.

–PCB a microonde con lavori sopra 2 Frequenza radio GHz.

Teflon PCB are used in different applications such as remote controls(controlli senza fili)sicurezza,smartphone,sensori ecc.

Le nuove tecnologie fanno sempre più uso di queste applicazioni RF.

Ciò richiede una produzione secondo elevati standard di qualità e la scelta dei giusti materiali RF a seconda dell'applicazione.

It is important that one knows the properties of the various materials. Choosing the right material is perhaps the most critical decision in the production process of the Teflon PCB.
