　　Flexible circuits, also known globally as flex circuits, flexible printed circuit boards, flex print, or flexi-circuits, are part of the electronic and interconnection family. They consist of a thin insulating polymer film with conductive circuit patterns affixed to it, usually coated with a thin polymer for protection.With the upsurge of industry development, RF PCB The expressive force in the market has also been very good, bringing many brand-new high-quality experiences to users. https://www.wellcircuits.com/

　　

　　The technology has been used for interconnecting electronic devices since the 1950s and is now a crucial interconnection technology in many advanced electronic products today.

　　Size and Weight Reduction Benefits of Flexible Circuitry

　　

　　Wiring solutions that fit where rigid boards cannot.

　　

　　Thin, lightweight products that are durable.

　　

　　Miniaturized versions of existing technologies.

　　

　　Three-dimensional packaging geometry.

　　

　　A low number of device interconnects.

　　

　　Shock and vibration resistance.

　　

　　These benefits highlight flexible circuitry as an ideal solution for mobile consumer electronics. Inside modern devices like smartphones and laptops, flexible circuitry plays a critical role.

　　

　　In mobile devices, using rigid circuitry would result in devices that are too large, heavy, and fragile to carry conveniently, exemplified by the Osborne I, the first fully powered mobile computer, weighing an intimidating 24.5 pounds. Size and weight reduction is only part of the flexible circuit story; they are also ideal for high-temperature and high-density applications.

　　

　　High Temperature and High-Density Applications

　　

　　Flex circuits, often made of polyimide or similar polymers, dissipate heat better than most rigid circuit board materials. This feature allows flexible circuits to be placed in locations where heat would impact the performance of rigid circuit boards.

　　

　　Flexible circuit boards can withstand extreme temperatures ranging from -200＜C to 400＜C, making them desirable for borehole measurements in the oil and gas industry and preferred in industrial sensor technologies for their small size and durability.

　　

　　High temperature resistance, combined with chemical resistance, excellent resistance to radiation and UV exposure, and the ability to control impedances in high-density designs, makes flexible circuits highly beneficial for manufacturers.

　　

　　Why Not Make All Circuit Boards Flexible?

　　

　　Flexible circuit boards are certainly useful, but they are not going to replace rigid circuit boards for all applications. Cost efficiency is the main obstacle to implementing an exclusively flexible circuit board design in a consumer product. Rigid circuit boards are less expensive to manufacture and install in a typical automated high-volume fabricating facility.

　　

　　Typically, the ideal solution for an innovative product is one that incorporates flexible circuitry when necessary, and employs solid, reliable rigid circuit boards where possible to keep manufacturing and assembly costs down.

　　Improper use of air conditioningknow Puremind Commercial Air Conditioners Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://puremind.com/puremind-hot-sale/

　　

　　Not only will it increase electricity consumption,

　　

　　It may even affect your health.

　　

　　Today, follow the Shanghai Health Promotion Center.

　　

　　Let’s learn the “cold knowledge” of air conditioning use ~

　　

　　Don’t “open and close for a while”

　　

　　I wonder if you have had such an experience?

　　

　　Caught in the strange circle of air conditioning turning on cold and turning off hot, repeated operation is always “cutting suitable”; Or go out and get a courier, thinking that it is more energy-saving to turn off the air conditioner first.

　　

　　In fact, often this behavior of frequently starting the air conditioner increases the power consumption and is not conducive to the maintenance of the air conditioner.

　　

　　Studies have proved that air conditioning “turns on and off for a while” does not actually save electricity. Therefore, if you only go out for a short time, you don’t have to turn off the air conditioner and turn it on again.

　　

　　Pay attention to “humidity” and “temperature”

　　

　　The muggy air has a high humidity, so it is uncomfortable to adjust the temperature. At this time, try to turn on the “dehumidification mode” after air conditioning refrigeration, and the air will become more refreshing and comfortable.

　　

　　If you need to stay in an air-conditioned room for a long time, remember to drink water properly to avoid the loss of water.

　　

　　Practice has proved that it is most appropriate to control the indoor and outdoor temperature difference at 6-8≧, mainly to reduce the burden on the thermoregulation center and avoid the symptoms of dizziness, headache and dry skin and mucosa. Therefore, the air conditioning temperature is set at 26 to 28≧.

　　

　　Don’t sweat and rush into the air-conditioned room.

　　

　　In hot summer, it is easy to sweat when you move a little and bask in the sun. Do you just want to rush into the air-conditioned room? At this time, you should be careful that the disease will come to you.

　　

　　For the general population, sudden cold and heat are easy to catch a cold, have a fever and have diarrhea; It is even more dangerous for patients with hypertension and coronary heart disease.

　　

　　The cardiovascular system in the original thermal environment is in a state of relaxation, and the sudden cooling air after entering the air-conditioned room makes the blood vessels contract urgently, which is prone to dangerous situations such as myocardial infarction.

　　

　　Therefore, don’t rush into the air-conditioned room after sweating, let the sweat collect first, or wipe your body with a dry towel first. When the air conditioner is just turned on, it should not be adjusted to a too low temperature, and at the same time, it should avoid cold air blowing directly on the head, neck and waist and abdomen.

　　

　　Do a good job cleaning

　　

　　The cleaning problem of air conditioning is often easily overlooked, and the bacteria hidden in it will take advantage of the opportunity to cause “air conditioning disease.”

　　

　　Legionella, which lurks in the daily artificial water environment, is such a pathogen. Water contaminated by bacteria can be inhaled by human body in the form of aerosol. After people are infected with Legionella, there will be symptoms similar to pneumonia, such as high fever, chills, fatigue, muscle pain, etc., which may even be life-threatening.

　　

　　The air conditioning system is the main “hiding point” of Legionella, so it is necessary to clean and disinfect the air conditioning; If it is a central air conditioner, the deposited cooling tower water should be replaced and the attached “dirty things” should be removed in time. Don’t forget to clean the casing and filter screen after the “air conditioning season”.

　　

　　In addition, it is recommended to open the window for ventilation every 2-3 hours to ensure the cleanliness of indoor air.

　　The weather was sultry and humid after entering the night.in fact rv air conditioner It is more and more welcomed by our customers, and its market performance is gradually improving. https://puremind.com/product-category/puremind-air-conditioner/rv-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

　　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.

　　Winter is coming, and many friends in the south are estimated to be inseparable from the company of air conditioning. Recently, some netizens who are familiar with the home appliance industry have summed up 10 cold knowledge about air-conditioning electric auxiliary heating. If you are afraid of cold, you may be able to learn it.In order to open the market, Puremind Solar Air Conditioners Constantly improve the ability of business development and create an extraordinary brand image for it. https://puremind.com/puremind-hot-sale/

　　

　　1. 38≧: According to the standard, the air outlet temperature should reach above 38≧ when air conditioning is heating, which is higher than human body temperature, otherwise it will feel like cold air when blowing on people.

　　

　　2, wind speed: air conditioning heating, high wind speed when the outlet temperature is low, low wind speed when the outlet temperature is high.

　　

　　3. Temperature: After the air conditioner is turned on for heating, the air outlet temperature of 40≧ is faster than that of 60≧. Because the hot air floats up, the high temperature of the outlet air will float up to the roof faster, and the lower temperature will help the middle and lower air to heat up.

　　

　　Comprehensive 2 and 3, if the air conditioner wants to heat well, it needs to turn on the large air volume, and after turning it on, the air will be discharged at 40≧ first, and then the air will be heated to about 50≧ after the room temperature rises.

　　

　　4. The purpose of electric auxiliary heat: it is to heat the air outlet temperature. When the outdoor temperature decreases, the heating performance of the air conditioner will be attenuated. Turning on electric auxiliary heat can increase the air outlet temperature and avoid people feeling cold wind blowing.

　　

　　5. When do you need to turn on the auxiliary heating? According to the national standard, when the outdoor temperature is above 0≧, the auxiliary heating of air conditioner is turned off by default, and users can turn it on manually. When the temperature is lower than 0≧, it is turned on by default, and the user can turn it off manually.

　　

　　6. Principle of electric auxiliary heating: The electric auxiliary heating is at the lower end of the internal heat exchanger, in front of the air outlet of the air conditioner, with PTC ceramic heating rods inside and aluminum fins outside. After electric auxiliary heating, the temperature will reach 200~300≧, so electric auxiliary heating can’t be dry-burned, and the air conditioner must be blown after it is turned on.

　　

　　7. Will electric auxiliary heating blow white powder? The consultant learned that in 2024, the air-conditioning models were sold, and the sleeve pieces had been passivated, or Teflon coating was sprayed on the surface to prevent white powder blowing. At present, the models on sale will not have the problem of blowing white powder.

　　

　　8. When defrosting the air conditioner, can you turn on the electric auxiliary heat to avoid excessive cooling of the room?

　　

　　No way. When the air conditioner is defrosting, the internal fan stops running, and the air conditioner does not give out air. If the electric auxiliary heat is turned on, it will dry up and may burn out the internal machine parts. When the air conditioner is defrosting, it is not good for the internal machine to keep blowing air.

　　

　　9. Air conditioners that do not stop defrosting. When some models defrost, the internal heat exchanger will heat up. Is the electric auxiliary heating turned on?

　　

　　No, electric auxiliary heating can only heat the outlet air temperature, but not the heat exchanger.

　　

　　10. Japanese air conditioners are good at heating without electricity, but domestic air conditioners are not good at heating with electricity.
