　　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.In the industry, PCB manufacturing in China Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. 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.

　　It’s getting hot, and it’s time to turn on the air conditioner. But can you really use air conditioning? Is it only cooling in summer and heating in winter? Air-conditioning remote controllers are generally equipped with a variety of use modes, and different modes have different use effects. Let’s take a look at it.In some cases, Marine Air Conditioner 220V The advantages will become more and more obvious, and it will be able to develop indomitable after market tests. https://puremind.com/product-category/puremind-air-conditioner/marine-air-conditioner/

　　Cool feeling mode

　　Applicable people: afraid of heat and cold.

　　Blowing the air conditioner in summer is cool, because the room temperature is lowered, and because the cold air blown by the air conditioner blows on the body, it plays the role of an electric fan.

　　The principle of the “cool feeling” function is simple: control the angle and speed of the air outlet to prevent the air conditioner from blowing at people-the traditional way is to adjust the angle of the air deflector and the speed of the fan, and the new air conditioner is even equipped with an infrared probe to prevent the wind from blowing directly at people, which is very friendly to people who are afraid of cold stars.

　　Air supply mode

　　Applicable scenario: when it is not too hot

　　Air conditioning is a combination of “cooling/heating+fan”, and the “air supply” function is to turn on the fan instead of starting the compressor, electric heating wire and other temperature-related components of the air conditioning.

　　If you want to improve the air quality, breathe and smell, you need air conditioning with fresh air system.

　　Eco mode

　　Applicable scene: before going to sleep

　　”eco”, the abbreviation of economic, is also called “energy saving” mode.

　　It is suggested that the air conditioner can be changed to this mode before going to bed. When you fall asleep at a comfortable room temperature, the air conditioner will change the temperature, increasing it in summer and decreasing it in winter. In short, it will reduce the power consumption until it is completely turned off, that is, the “sleep” mode.

　　Dehumidification mode

　　Applicable scene: hot and humid weather

　　Both “dehumidification” and “refrigeration” modes will produce refrigeration effect. The difference is that after the “dehumidification” mode is turned on, the air conditioner will appropriately cool the indoor air, let the water vapor condense into water, and then discharge it to the outside-reducing the indoor humidity, and people’s body temperature will be cooler. The main purpose of the “refrigeration” mode is to reduce the indoor temperature, and the water vapor in the condensed air is an incidental effect.

　　From the effect point of view, after opening the “dehumidification” mode, although the air conditioning temperature is not very low and it does not consume too much electricity, it will be more comfortable.

　　It should be noted that this function is only effective in areas with humid climate. If you live in a dry area, this function is not recommended.

　　Automatic mode

　　Applicable people: people who need indoor constant temperature and people who use company air conditioning.

　　To choose this mode, you need to set a temperature first, say 26 degrees Celsius. If the room temperature is lower than 26 degrees Celsius, the air conditioner will start heating; If the room temperature is higher than 26 degrees Celsius, the air conditioner will start to cool.

　　Auxiliary heating mode

　　Applicable scene: when you just enter the house in winter and are about to be frozen.

　　There are two ways to heat by air conditioning. One is a porter who relies on heat-compressor. From the thermodynamic point of view, using compression mechanism to save heat and electricity, but the heating speed is slow, and when it is particularly cold outdoors, such as below 0 degrees Celsius, the heating efficiency will become low.

　　The other is the producer of heat-electric heating wire. “Auxiliary heating” is the option of turning on the electric heating wire, which can assist the compressor to achieve the effect of rapid heating. After the room temperature reaches the set temperature, just keep the temperature by the compression mechanism. At this time, the “auxiliary heating” function can be turned off in order to save electricity.

　　Everyone can use these functions as much as possible. After all, we spent thousands of dollars to buy an air conditioner, and if we don’t drain all its functions, we will lose money!

　　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.Under people’s attention commercial hvac systems Finally grow into what people need, born for the market and come for the demand. https://puremind.com/product-category/puremind-air-conditioner/commercial-air-conditioner/

　　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.

However, in other words, we should know more about it. cnc milling services The law of development has brought new vitality to the whole industry and revitalized the market. https://www.ultirapid.com/services/cnc-machining/

Cairo, March 19 (Reporter Wang Shang) News from Sana’a: Yemen’s Houthi spokesman Yahya Sareya issued a statement on the 19th saying that the Houthi armed forces fired multiple missiles at an American ship, the Maduo, sailing in the Red Sea.

Sarea did not disclose the specific time of the attack. Sarea also said that the Houthi armed forces used missiles to attack the Israeli Red Sea city of Eilat and hit the target accurately.

Relevant shipping information shows that the Maduo is a liquefied natural gas vessel flying the flag of the Marshall Islands and operated by a Greek company. Until February this year, the ship had been operated by ExxonMobil Oil of the United States.

The British Maritime Trade Action Office had previously reported that the Maduo was attacked twice by missiles in the Red Sea on the 15th and in the Gulf of Aden on the 17th. No casualties or hull damage were caused.

According to the Israel Defense Forces on the 17th, a suspicious aircraft entered Israeli airspace from the Red Sea that night and fell into an open space in northern Eilat, causing no casualties or property damage.

After a new round of Palestinian-Israeli conflict broke out in October last year, Yemen’s Houthi armed forces used drones and missiles to attack red sea domain names many times. Since January 12 this year, the United States and Britain have launched air strikes on Houthi targets many times, causing casualties. Some countries have condemned the actions by the United States and Britain as a violation of Yemen’s sovereignty and will aggravate regional tensions.

　　What is a fixed-frequency air conditioner? The grid voltage in China is 220 volts and 50 hertz, and the air conditioner working under this condition is called a fixed-frequency air conditioner. Because the power supply frequency can’t be changed, the rotating speed of the compressor of the traditional fixed frequency air conditioner is basically unchanged, and the indoor temperature can be adjusted by constantly “turning on and off” the compressor, which is easy to cause the room temperature to be hot and cold and consume more electricity.To some extent, industrial water chiller Our development has surpassed many peer businesses, but it has never stopped moving forward. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

　　What is a variable frequency air conditioner? The main engine of the variable frequency air conditioner automatically performs stepless speed change, and it can automatically provide the required cooling (heating) amount according to the room conditions. When the indoor temperature reaches the expected value, the air conditioning main engine will run at a constant speed that can accurately maintain this temperature, so as to realize “non-stop operation”, thus ensuring the stability of the environmental temperature.

　　Advantages and disadvantages analysis:

　　Advantages of fixed frequency air conditioning: affordable price, more options, rich products and various types.

　　Disadvantages of fixed frequency air conditioning: Relative temperature control and energy saving are still slightly inferior to frequency conversion.

　　Advantages of inverter air conditioner: more accurate temperature control, low temperature, wide voltage start, and more energy saving.

　　Disadvantages of inverter air conditioner: the relative price positioning is higher, while the affordable inverter is less optional.

　　To sum up, it is obvious that inverter air conditioners are smarter! But the price will naturally be more expensive.

According to a report by the Wall Street Journal on July 15, people familiar with the matter revealed that business tycoon Elon Musk said he plans to donate about $45 million a month to a new super political action committee that supports former President Trump.

Reported that other supporters of the newly established U.S. Political Action Committee include Palantil technology co-founder Joe Lonsdale, the Winkleworth brothers, former U.S. ambassador to Canada Kelly Craft and her husband Joe Craft.

According to a person familiar with the matter, the political action committee, established in June, is mainly responsible for registering voters, persuading voters to vote as soon as possible, and requiring ballots to be mailed in swing states.

Musk is currently the richest man in the world, with an estimated wealth of more than US$250 billion. But the amount of donations he said was also staggering.

According to reports, the largest known campaign donation in 2024 to date is $50 million, donated by the great-grandson of banker Thomas Mellon to support one of Trump’s super political action committees.

According to documents submitted on the 15th, as of June 30, the U.S. Political Action Committee received a total of US$8.75 million in donations. A person familiar with the matter said Musk said he plans to start donating in July.

The report also said that Musk officially expressed support for Trump shortly after the shooting. He posted on social platform X: The last time a presidential candidate encountered such a severe test was Theodore Roosevelt. (Compiled by Pan Xiaoyan)
