Carte PCB en téflon F4BM à deux couches

 

The PCB material used by teflon PCB, F4BM is laminated by glass woven cloth, film adhésif, 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, haute isolation, high lubrication, non adhesion and non toxicity. Cependant, 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. En outre, 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) sont une technique de plus en plus utilisée dans l'industrie des PCB.

–PCB RF à haute fréquence avec travaux ci-dessus 100 MHz.

–PCB micro-ondes avec travaux ci-dessus 2 Fréquence radio GHz.

Teflon PCB are used in different applications such as remote controls(commandes sans fil)sécurité,téléphones intelligents,capteurs, etc..

Les nouvelles technologies utilisent de plus en plus ces applications RF.

Cela nécessite une fabrication selon des normes de qualité élevées et le choix des bons matériaux RF en fonction de l'application..

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.
