PCB Blog - Features of Teflon PCB

Teflon PCB, whose scientific name is polytetrafluoroethylene (abbreviated as PTFE), is generally called "non stick coating" or "easy to clean material". This material has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used as an ideal coating for easy cleaning of the inner layer of water pipes, as well as for PCB proofing of high-end electronic products. This is another common material for PCB production. Teflon is a light and strong material. This material is common in applications requiring strict tolerances. Teflon will not expand at high temperatures. One of the advantages of this material is that it is flame retardant. Due to the properties of this material, it is very suitable for high-speed applications. Teflon has physical strength and provides temperature balance.

Teflon PCB has a series of excellent performances

Material selection: This is the first step in making Teflon PCB samples. Wangling f4b, Rogers 5 series and Rogers 3 series are all Teflon PCB. Plastics are commonly used for flexible PCB prototyping. PTFE is a useful material for PCB manufacturing. Teflon PCB has its unique advantages.

Function test: After the Teflon Teflon PCB sample is made, the board passes the function test to access its functions as expected.

Temperature resistance: Teflon circuit board can withstand extreme cold and heat. This is one of the main reasons why it is used in military and aerospace applications. The plate can operate in the temperature range of - 454 to 600 ° F and - 270 to 315 ° F. It can withstand any temperature and prevent cracking.

High dielectric strength: due to the high dielectric strength of the plate, it does not conduct electricity. It works perfectly as an insulator. The insulating power of this material can protect the equipment from electric breakdown.

Durability: PTFE PCB is an ideal choice because it is very durable. It can withstand oxidation, UV, embrittlement or discoloration. Because of its durability, it is a cost-effective option.

Mechanical rigidity: Teflon PCB has mechanical stability. This makes it ideal for applications exposed to high levels of mechanical stability. Teflon PCB has good thermal conductivity.

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

Low temperature resistance: soft at - 100 ℃;

Corrosion resistance: resistant to aqua regia and all organic solvents; 

Weather resistance: the best aging life of plastics;

High lubrication: it has the minimum friction coefficient (0.04) among plastics;

Non sticky: it has the minimum surface tension among solid materials without adhering to any substance;

Physiological inertia: With excellent electrical performance, it is an ideal class C insulating material. A thick layer of newspaper can block 1500V high voltage; It's smoother than ice.

Teflon PCB has excellent comprehensive performance, high temperature resistance, corrosion resistance, non stick, self-lubricating, excellent dielectric performance, and very low friction coefficient. In PCB proofing, Teflon is a high-frequency board with very excellent performance, which is very suitable for applications in radar, high-frequency communication equipment, wireless electrical appliances and other fields. Generally, in PCB board proofing, general manufacturers seldom use such plates.
