Teflon PCB

Teflon PCB in high-end electronic products uses Teflon laminate material.

The scientific name of Teflon is polyt etrafluor oethylene

(PTFE) This material is resistant to acid, alkali, and various organic solvents, and is almost insoluble in all solvents. At the same time,
1.Teflon material has the characteristics of high temperature resistance and a very low dielectric coefficient, making it an ideal high-frequency PCB material for high-frequency Teflon PCB.

2.Teflon PCB has a series of excellent properties:

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

4.Low temperature resistance: still soft at -100 degrees;

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

6.Weather resistance: the best aging life among plastics;

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

Non-stickiness: It has the smallest surface tension among solid materials and does not adhere to any substance;

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

Teflon has outstanding comprehensive performance, high temperature resistance, corrosion resistance, non-stick,
Self-lubricating, excellent dielectric properties, and extremely low friction coefficient. In Teflon PCB,
Teflon is a high-frequency PCB material with excellent performance, which is very suitable for application in radar, high-frequency communication equipment,
Radio equipment and other fields. Usually in Teflon PCB, general manufacturers rarely use this Teflon sheet. Zhongbo can provide Teflon PCB to meet various PCB needs of customers.
At present, in the manufacture of Teflon PCB by Zhongbo, Teflon PCB materials can be pressed 4 to 6 layers in pure pressure and 4 to 8 layers in mixed pressure.

Teflon PCB

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

1. Income

Both Teflon PCB and low-frequency power supply circuit have the function of voltage gain and output power collection. For the resonant differential amplifier circuit,
It refers to the resonant frequency F0, and for the optical 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 the resonant differential amplifier circuit,
Most of the pointers refer to the value between the two frequencies when the normalized amplitude of the resonant frequency f0 drops to 0.707;
For the fiber broadband amplifier circuit, it refers to the corresponding frequency.

3. Selectivity

Selectivity is mainly for the resonant amplifier circuit.
It characterizes the circuit’s selection of useful signals and the ability to suppress useless signals.
It is usually based on the resonant characteristic curve of the circuit and measured by rectangular coefficient and suppression ratio.

4. Noise coefficient

When the amplifier circuit is working, due to the influence of certain factors, the fluctuation will move irregularly, forming noise inside the circuit, affecting the quality of the signal.
This influence is usually described by the ratio of signal power PS to noise power PN (SNR). The noise coefficient is the ratio of input signal noise to 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 change.
For example, when the ambient temperature changes or the power supply voltage fluctuates, it will affect the normal state of the DC operation of the amplifier circuit;
The parameters of the circuit components will also change accordingly, causing the gain of the amplifier circuit to change,
The center frequency to shift, and the resonance curve to suddenly change greatly. In the end, it may not work at all.

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

1. Definition of high-frequency Teflon PCB.

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

Teflon PCB

With the rapid development of science and technology, many types of equipment are planned in the microwave frequency band (>1GHz) or even the millimeter wave (30ghz) range. It can be seen that the frequency is getting higher and higher, and the requirements for Teflon PCB boards are also higher. For example, the substrate needs to have high-quality electrical properties and chemical stability. As the frequency of the power signal increases, the loss of the board 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 amplifiers, low noise amplifiers, etc.

2.3 Passive devices such as power dividers, couplers, duplexers, filters, etc.

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