What is Teflon PCB board and what are its characteristics?

date:2020-11-11 16:22:28

Teflon, the scientific name is polytetrafluoroethylene (abbreviated as PTFE), is generally called "non-stick coating" or "easy to clean material". This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon has the characteristics of high temperature resistance, its friction coefficient is very low, so it can be used as lubrication, and it has become an ideal coating for easy cleaning of the inner layer of water pipes. It can also be used in PCB proofing of high-end electronic products.

Teflon has a series of excellent performance:

* High temperature resistance: long-term use temperature 200~260 degrees;

* Low temperature resistance: still soft at -100 degrees;

* Corrosion resistance: can withstand aqua regia and all organic solvents;

* Weather resistance: the best aging life among plastics;

* High lubrication: has the smallest coefficient of friction in plastics (0.04);

* Non-sticky: It has the smallest surface tension among solid materials without adhering to any substance;

* It is physiologically inert; it has excellent electrical properties and is an ideal C-level insulating material. A thick layer of newspaper can block the high voltage of 1500V; it is smoother than ice.


Teflon has outstanding excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, and very low friction coefficient. In PCB proofing, Teflon PCB board is a high-frequency board with very excellent performance, which is very suitable for applications in radar, high-frequency communication equipment, radio equipment and other fields. Usually in PCB proofing, ordinary manufacturers seldom use this kind of board. FASTPCBA can provide Teflon PCB board to meet customers' various PCB proofing needs. At present, in the PCB proofing of FASTPCBA, the Teflon PCB board can achieve 4~6 layers of pure pressure and 4~8 layers of mixed pressure.
