PTFE PCB High Frequency Circuit Board Factory

PTFE PCB High Frequency Circuit Board Factory

With the continuous advancement of science and technology and people's pursuit of electronic products, intelligent, high-security performance, and the emergence of pollution-free electronic products, the selection of materials for circuit board products is also diversified. Nowadays, PTFE high-frequency materials are used in a wider range of applications, involving various kinds of intelligent electronic and electrical products. For example, antennas are the most common. Nowadays, space, military, communications, digital, and medical industries are inseparable from high-frequency materials. application. There are many different types and specifications of high-frequency materials according to the suppliers. Let's talk about some characteristics and applications of PTFE high-frequency materials.

PTFE sheet is mainly used as electrical insulating material and carrier board for contact with corrosive media. It is mainly used for supporting sliders, track seals and lubricating materials. It is now widely used in chemical and pharmaceutical applications along with the development of science and technology. Dye industry containers, storage tanks, reactor towers, anti-corrosion lining materials for large pipelines; machinery, construction, aerospace, military, communications, traffic bridge slider, rail; printing and dyeing, light industry, textile industry, anti-sticking materials. This is especially common in PCB circuit board manufacturers. The following is the production of high-frequency circuit boards using high-frequency materials.

Teflon substrate advantages:

1,high temperature - using the working temperature of 250 °C.

2,low temperature resistance - with good mechanical toughness; even if the temperature dropped to -196 °C, it can maintain 5% elongation.

3,Corrosion resistance: Indifference to most chemicals and solvents, resistance to strong acids and alkalis, water and various organic solvents.

4,Weather resistance - The best aging life in plastic.

5,High lubrication - is the lowest friction coefficient in solid materials.

6,non-adhesion - is the smallest surface tension in solid materials, no adhesion of any material, mechanical properties of its friction coefficient is very small, only 1/5 of polyethylene, which is an important feature of the surface of the perfluorocarbon . Because of the extremely low intermolecular forces between fluorine-carbon chains, PTFE has no stickiness.

7,non-toxic - with physiological inertia, as a long-term implantation of artificial blood vessels and organs without adverse reactions.

8,Good electrical performance—The dielectric constant and dielectric loss of PTFE in a wide frequency range are low, and the breakdown voltage, volume resistivity, and arc resistance are all high.

Teflon substrate (also called PTFE, Teflon) is divided into two types: mold pressing and turning. Molded sheet is formed of PTFE resin at room temperature by molding method and then sintered. Cooled and made. Teflon turning plate is made of PTFE resin by compaction, sintering and rotary cutting. Its products are widely used and have extremely superior comprehensive performance: high and low temperature resistance (-192°C-260°C), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, no adhesion, Non-toxic and other excellent features.
