　　What is High Frequency (HF) PCB?Under people’s attention PCB manufacturing in China Finally grow into what people need, born for the market and come for the demand. https://www.wellcircuits.com/

　　

　　High Frequency PCB

　　

　　In today¨s technological landscape, high-frequency electronic devices are becoming increasingly essential, particularly in wireless networks. The rapid growth of satellite communications and the shift toward high-speed, high-frequency information products demand the use of high-frequency substrates. Devices like satellite systems, mobile phone base stations, and other communication products require high-frequency PCBs for optimal performance.

　　

　　Key Features of High Frequency PCBs

　　

　　High Frequency PCB Features

　　

　　The dielectric constant (DK) should be small and stable, with lower values minimizing signal delay.

　　

　　The dissipation factor (DF) should also be low to ensure high-quality signal transmission, reducing signal loss.

　　

　　Thermal expansion properties should be matched with the copper foil to prevent separation due to temperature variations.

　　

　　Water absorption must be low, as higher absorption can negatively impact the dielectric constant (DK) and dissipation factor (DF) in humid environments.

　　

　　The material must exhibit excellent heat resistance, chemical resistance, impact endurance, and peel strength.

　　

　　Materials Used in High-Frequency Circuit Boards

　　

　　Materials for High Frequency PCBs

　　

　　High-frequency PCBs for wireless applications and high-speed data transmission, especially those in the GHz range, require specific material properties:

　　

　　Adapted permittivity (dielectric constant).

　　

　　Low attenuation to ensure efficient signal transmission.

　　

　　Homogeneous construction with low tolerances in insulation thickness and dielectric constant.

　　

　　Typically, high-frequency is defined as frequencies above 1 GHz. Currently, PTFE (polytetrafluoroethylene), commonly known as Teflon, is widely used for high-frequency PCBs, especially those operating above 5 GHz. FR4 and PPO substrates are commonly used for frequencies between 1 GHz and 10 GHz. The differences between these materials are as follows:

　　

　　Regarding laminate cost, FR4 is the least expensive, while Teflon is the most costly. In terms of dielectric constant (DK), dissipation factor (DF), water absorption, and frequency characteristics, Teflon outperforms the other substrates. For applications requiring frequencies above 10 GHz, Teflon is the optimal choice, despite its higher cost and poorer heat resistance properties. To enhance the thermal and mechanical properties of PTFE, fillers like SiO2 or fiberglass are added. Additionally, because PTFE has molecular inertia and doesn¨t easily bond with copper foil, special surface treatments (such as chemical or plasma etching) are used to improve adhesion, though these may affect the dielectric performance.

　　The weather was sultry and humid after entering the night.Before that, commercial heating and cooling The market has also soared for a time, which has attracted the attention of a wide range of investors. https://puremind.com/product-category/puremind-air-conditioner/commercial-air-conditioner/

　　

　　The frequency of air conditioning is increasing.

　　

　　Hot summer day

　　

　　Is it advisable to stay in an air-conditioned room for a long time?

　　

　　Do I need to open the window to ventilate the air conditioner?

　　

　　The answer is coming ◎

　　

　　Turning on the air conditioner should not close the doors and windows.

　　

　　A set of experiments will show you.

　　

　　Many people have been in air-conditioned rooms for a long time.

　　

　　I will feel dizzy and sleepy.

　　

　　This may be that the indoor carbon dioxide concentration exceeds the standard.

　　

　　Experts said

　　

　　National standard of indoor carbon dioxide concentration

　　

　　The general requirement is below 1000ppm.

　　

　　For shopping malls, schools and other densely populated places

　　

　　Generally, the concentration of carbon dioxide is required to be below 1500ppm.

　　

　　When the indoor carbon dioxide concentration reaches 2000ppm

　　

　　The human body often feels dizzy and uncomfortable.

　　

　　There are only two or three people in the family.

　　

　　Why does the concentration of carbon dioxide exceed the standard?

　　

　　Two experimenters are in a 13-square-meter bedroom

　　

　　Close the doors and windows and turn on the air conditioner.

　　

　　By placing a good observer

　　

　　Real-time observation of indoor carbon dioxide concentration changes

　　

　　Over time

　　

　　The concentration of carbon dioxide keeps rising.

　　

　　Just half an hour.

　　

　　It has already exceeded 1500ppm.

　　

　　Experts said

　　

　　For the home environment

　　

　　This concentration has exceeded the standard

　　

　　after an hour

　　

　　The concentration of carbon dioxide in the air

　　

　　More than 2000ppm

　　

　　And it’s rising

　　

　　The experimenter opened the window for ventilation.

　　

　　After 15 minutes.

　　

　　Indoor carbon dioxide concentration

　　

　　Slowly dropped below 1000ppm.

　　

　　It can be seen that the doors and windows are closed and the air conditioner is turned on for 1 hour.

　　

　　It may cause the indoor carbon dioxide concentration to exceed the standard.

　　

　　If you sleep in this environment for one night,

　　

　　It is very likely that lack of oxygen will bring health risks.

　　

　　It is recommended to turn on the air conditioner.

　　

　　Open the window properly to get some air.

　　

　　For families that are inconvenient to open windows

　　

　　Consider purchasing a new fan.

　　

　　Instead of window ventilation

　　

　　Air-conditioned rooms should not stay long.

　　

　　Beware of “air conditioning disease”

　　

　　It is hot and hot in summer.

　　

　　Stay in an air-conditioned room for a long time

　　

　　Not only dizziness, headache

　　

　　It may also induce “air conditioning disease”

　　

　　Knowledge of small science popularization

　　

　　”Air-conditioning disease” is a series of diseases induced by long-term use of air conditioning. When using air conditioning, the space is relatively closed, the air is not circulating, pathogenic microorganisms are easy to breed, and the temperature difference between indoor and outdoor is large, so the body is not well adapted, so a series of symptoms will appear.

　　

　　Abdominal pain and diarrhea

　　

　　The stomach and intestines are very sensitive to the stimulation of temperature.

　　

　　Excessive indoor and outdoor temperature difference

　　

　　Accelerated gastrointestinal peristalsis

　　

　　Cause digestive dysfunction

　　

　　Cause abdominal pain and diarrhea

　　

　　catch a cold and have a fever

　　

　　Enter the room with low temperature from the hot outdoor.

　　

　　Easy to catch a cold and cough.

　　

　　Even induce asthma and pneumonia.

　　

　　Serious illness

　　

　　neck shoulder lumbocrural pain

　　

　　Thin clothes in summer

　　

　　Shoulder, knee, waist, etc.

　　

　　Exposed to the cool breeze for a long time

　　

　　It is easy to cause symptoms such as joint and muscle pain.

　　

　　It is easy to cause cervical spondylosis and scapulohumeral periarthritis.

　　

　　cardiac infarction

　　

　　From low temperature indoor to high temperature outdoor.

　　

　　Switch like this

　　

　　Will make blood vessels suddenly contract and expand.

　　

　　Repeated fluctuation of blood pressure may induce myocardial infarction.

　　

　　For the elderly with fragile blood vessels,

　　

　　be highly dangerous

　　

　　How to blow air conditioning healthily?

　　

　　Pay attention to these points!

　　

　　Air conditioning should be cleaned regularly.

　　

　　Whether it’s central air conditioning

　　

　　Or a stand-alone air conditioner at home

　　

　　It should be cleaned before use.

　　

　　It is recommended to clean it once every 1~2 months after use.

　　

　　Window ventilation is essential.

　　

　　Turn on the air conditioner

　　

　　Attention should be paid to frequent ventilation.

　　

　　It is recommended that every 2~3 hours.

　　

　　Just ventilate the room once.

　　

　　Ventilation for 10 to 15 minutes each time.

　　

　　Air conditioning wind blows upward.

　　

　　The temperature should not be too low.

　　

　　Cold air will stimulate sweat pores to contract suddenly.

　　

　　It is easy to cause dizziness, headache, runny nose,

　　

　　Symptoms such as joint pain.

　　

　　It is suggested that the temperature of air conditioner should be adjusted to 26≧

　　

　　The temperature difference between indoor and outdoor should not exceed 7≧

　　

　　When the air conditioner is turned on, the cold air sinks.

　　

　　So the wind had better blow upward.

　　

　　Avoid cold air blowing directly on your body.

　　

　　Drink more warm water.

　　

　　To prevent water loss from the body

　　

　　Causes dry skin and itchy throat.

　　

　　Drink plenty of warm water.

　　

　　Drink chrysanthemum tea, etc

　　

　　Eat more fresh fruits rich in vitamins.

　　01In the long run, Marine Air Conditioner 115V The value will be higher and higher, and there will be a great leap in essence. https://puremind.com/product-category/puremind-air-conditioner/marine-air-conditioner/

　　

　　If you leave home for a day …

　　

　　Kureczka said: “If you just leave home for one day, it is more energy-saving to turn on the air conditioner, but you should raise the temperature by several degrees instead of keeping the comfortable temperature set at home.”

　　

　　If the house is unoccupied for only a day or two, the same direction applies.

　　

　　It’s not necessarily a bad thing to turn off the air conditioner during the day. Either way, the speed of the air conditioner is the same-it just takes longer to cool the hot space. In fact, if you drive at normal temperature all day, you may consume more energy than if you turn it off and have a meeting at night.

　　

　　Air conditioning is not only to cool the space, but also to greatly reduce the humidity level. When the air conditioner is turned off for more than a few hours, the humidity level begins to rise, which may easily lead to mold growth, damage to electronic products, and warping and deformation of wood products. In addition, pets left at home may also be at risk of overheating and discomfort, which may occur especially in hot and humid climate.

　　

　　This is why it is suggested to turn on the air conditioner, but turn up the temperature. The U.S. Department of Energy pointed out that higher indoor temperature will actually slow down the flow of heat into the house, thus saving energy and money.

　　

　　When you get home, don’t turn the air conditioner down too low to “speed up” the cooling process, so that the room won’t get cold faster, and it will only increase energy consumption (cost money).

　　

　　02

　　

　　If you leave home for more than two days …

　　

　　If the whole family (including pets) has been away from home for more than two days, the equipment can be turned off. Kureczka said, “Turn off the air conditioner, and you can save a lot of energy and bills.”

　　

　　This means that when you come back, the temperature inside the room may not be very good and you will feel stuffy. Kureczka suggested, “Installing an intelligent thermostat is a good way to monitor and control the energy efficiency of your home, even if you are not at home-you can turn up the temperature before you leave and then turn it down on your way home.”

　　

　　She also suggested that if you go out for more than a few hours, please close the curtains, which can effectively block the sun, so that the air conditioning unit does not have to work so hard. Especially in areas with extreme temperatures, this will make a huge difference.

　　

　　03

　　

　　At home …

　　

　　The US Department of Energy and the Environmental Protection Agency suggest that the thermostat should be set to 26≧ or higher during the day, 28≧ when sleeping and 29≧ when going out.

　　

　　Think this setting temperature is too high? When the temperature is reduced to 26≧, compared with 22≧, it can save 25% of the electricity bill.

　　

　　Kureczka said: “It varies from person to person to adjust the temperature as high as possible while maintaining comfort. Generally speaking, increasing the temperature by 1 C will help reduce the cooling cost by 5%. “

　　

　　If it is acceptable to adjust the temperature higher than you are used to, then other measures may also make you feel comfortable, such as using ceiling fans. But the ceiling fan will not change the temperature, so remember to turn off the electric fan when you leave the room. Otherwise, you have to pay unnecessary electricity bills.

　　

　　Finally, try to ensure that the house is insulated, so that cold air will not escape and hot air will not sneak in.

Abidjan, March 15th: Cote d’Ivoire’s network communication services began to gradually resume on the 15th after 24 hours of widespread interruption across the country due to the rupture of submarine optical cables.

A major network operator in Cote d’Ivoire said the problem that caused the interconnection outage has been partially resolved and the resolution is continuing.

Four submarine optical cables serving West Africa suddenly broke on the 14th, causing the interruption of fixed and mobile network services provided by many telecom operators and Internet service providers in Cote d’Ivoire. It is reported that this incident affected more than ten African countries including Cote d’Ivoire, Liberia, Benin, Ghana, and Burkina Faso.

Cote d’Ivoire’s Minister of Digital Transformation and Digitalization Konat said in a statement on the 15th that the interruption of the national network in Cote d’Ivoire is an unprecedented special event, and the government is taking measures to restore network connectivity within the next 48 hours to minimize the impact on the economy and people’s daily lives.

According to officials from the Ministry of Digital Transformation and Digitalization of Cote d’Ivoire, the two major network operators in Cote d’Ivoire have switched to a cable that is still operating normally to gradually restore network communication services. (Reporter Zhang Jian)
