Product Details

Teflon PCB in high-end electronic products uses Teflon laminate material. The scientific name of Teflon is polytetrafluoroethylene (PTFE). This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon material has the characteristics of high-temperature resistance, and its dielectric coefficient is very low, so it is an ideal high-frequency PCB material for high-frequency Teflon PCB.

Teflon PCB has a series of excellent performances:

  • 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 a very low coefficient of friction. Among Teflon PCB, Teflon is a high-frequency PCB material with very excellent performance, which is very suitable for applications in radar, high-frequency communication equipment, radio equipment, and other fields. Usually, in Teflon PCB, general manufacturers seldom use this kind of Teflon sheet, UGPCB can provide Teflon PCB to meet customers’ various PCB needs. At present, in the manufacture of Teflon PCB for UGPCB, Teflon PCB material can achieve 4~6 layers of pure compression; 4~8 layers of mixed compression.

The characteristics of Teflon PCB board

The characteristics of Teflon PCB board mainly include the following categories:

1. Income

Both the Teflon PCB and the low-frequency power supply circuit have the effect of voltage gain and output power harvesting. Resonant differential amplifier circuit, it refers to the resonant frequency F0, for fiber broadband differential amplifier circuit, it refers to a frequency region.

2. Passband

The concept of low-frequency power supply PCB is not bad. For resonant differential amplifier circuits, most of the pointers refer to the value between the two corresponding frequencies when the normalized vibration amplitude of the resonant frequency f0 drops to 0.707; for fiber optic broadband amplifier circuits, it refers to It means corresponding to a certain frequency.

3. Selectivity

The selectivity is mainly for the resonant amplifier circuit, which characterizes the circuit’s selection of useful signals and its ability to suppress unwanted signals. It is usually measured by rectangular coefficient and suppression ratio based on the circuit’s resonance characteristic curve.

4. Noise figure

When the amplifying circuit is working, due to some factors, the fluctuations will move irregularly, forming noise inside the circuit, which will affect the quality of the si
