    Product Details Data Sheet

    Teflon PCB in high-end electronic products uses Teflon 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 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 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, ipcb can provide Teflon PCB to meet customers' various PCB needs. At present, in the manufacture of Teflon PCB for ipcb, Teflon pcb material can achieve 4~6 layers of pure compression; 4~8 layers of mixed compression.

    Teflon PCB

    The characteristics of Teflon PCB mainly include the following categories:

    1. Income

    Both the Teflon high frequency 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 signal. This effect is usually described by the ratio of signal power PS to noise power PN (SNR). The noise coefficient is the comparison between input signal noise and output signal noise.


    5. Stability

    The stability of high-frequency Teflon PCB refers to the stability of its main performance when the working state or working conditions are changed. For example, when the temperature of the environment changes or the voltage of the power supply fluctuates, it will affect the normal state of the DC operation of the amplified circuit; the parameters of the circuit components will also change accordingly, which will cause the gain of the amplifier circuit to change , The frequency shift of the center and the curve of resonance suddenly change greatly. In the end, it may not work at all.


    Brief description: High-frequency Teflon PCB is mainly: high income, high receiving signal, wide range, low noise figure, and high stability.

    1. The definition of high frequency Teflon PCB

    High-frequency Teflon PCB refers to PCBs with higher electromagnetic frequencies used in high-frequency (frequency higher than 300MHz or band length not higher than 1m) and microwave (frequency higher than 3GHz or wavelength not higher than 0.1m). It is a PCB produced on microwave Teflon copper clad laminates using ordinary rigid circuit board manufacturing methods or special processing methods. Generally speaking, high-frequency Teflon PCB can be regarded as a PCB with a frequency above 1GHz.


    With the rapid development of science and technology, many equipment are planned in the microwave frequency band (>1GHz) or even millimeter wave (30ghz) range. It can be seen that the frequency is getting higher and higher, and the requirements for Teflon PCB board are also higher. For example, the base material needs to have high-quality electrical properties and chemical stability. As the frequency of the power signal increases, the loss of the sheet is very small, and the importance of high-frequency Teflon PCB is becoming increasingly prominent.


    Second, the scope of application of high-frequency Teflon PCB

    2.1 Related to lighting and communication systems

    2.2 Power amplifier, low noise amplifier, etc.

    2.3 Passive components such as power splitters, couplers, duplexers, filters, etc.

    2.4 In the fields of automobile anti-collision systems, satellite systems, and radio systems, high-frequency electronic equipment is a development trend.
