  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.

What is High-Frequency PCB – An Overview of PCB Basics – Wellcircuits

  What is High Frequency (HF) PCB?pass FLEX PCB As can be seen from its market performance, it has strong vitality and strong appeal. 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.

Basic knowledge of refrigeration and air conditioning is a must for beginners ~

  There are many kinds of refrigeration methods, such as gas expansion refrigeration, liquid gasification refrigeration, vortex tube refrigeration and thermoelectric refrigeration. Among them, liquid gasification refrigeration is the most widely used, and its working principle is to realize refrigeration by using the heat absorption of liquid gasification.In addition to these aspects, industrial cooling systems The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://puremind.com/product-category/puremind-air-conditioner/industrial-chiller/

  

  1, the working principle of air conditioning (mainly refrigeration, heating on the contrary):

  

  The high-temperature and high-pressure refrigerant discharged from the compressor flows through the outdoor heat exchanger through the four-way valve, and dissipates heat to the outdoor air through heating transfer, and the refrigerant changes from gaseous state to liquid state-throttles and depressurizes through capillary (or solenoid valve)-one-way valve-filter-two-way valve (outdoor high-pressure pipe)-enters the indoor heat exchanger to absorb heat (realize refrigeration)-outdoor three-way valve (outdoor low-pressure pipe). Complete a single-loop refrigeration cycle.

  

  2. Types of components in refrigeration system:

  

  The air conditioning refrigeration system is mainly composed of four parts and some auxiliary equipment in the refrigeration system.

  

  The four major pieces are:

  

  compressor

  

  condenser

  

  Throttle mechanism

  

  Evaporator composition.

  

  Auxiliary equipment:

  

  Oil separator;

  

  Drying filter;

  

  Liquid storage tank;

  

  Electromagnetic four-way reversing valve;

  

  Solenoid valve; Check valve

  

  3, the working principle of each component

  

  Compressor: As the “heart” of refrigeration system, it has an important influence on the performance, noise, energy consumption, vibration and service life of air conditioning. According to the principle of thermodynamics, it can be divided into volumetric type and velocity type.

  

  Volumetric type: a certain volume of gas is sucked into the cylinder and the internal volume of the cylinder is changed to realize gas compression and forced discharge.

  

  Speed type: make the inhaled gas get a certain speed, and then slow down, so that kinetic energy can be converted into pressure energy and then discharged. The growth of gas is converted from speed.

  

  one

  

  Scroll compressor: It is formed by meshing two vortexes of stator and rotor.

  

  Rotor compressor: it consists of spindle with eccentric wheel, cylinder, sleeve, air inlet, slide plate, spring, exhaust valve and exhaust port.

  

  Condenser: The condenser transfers the refrigerating capacity of the evaporator in the refrigeration system to the environmental medium (cooling water or air) together with the power consumption of the compressor. According to cooling, it can be divided into air-cooled type, water-cooled type and evaporative type. When cooling, it mainly radiates heat to the outside, and when heating, it absorbs heat to the outside.

  

  Evaporator: The main function of the evaporator is to boil and evaporate the low-temperature and low-pressure refrigerant liquid that has entered the throttle in the evaporator, absorb the heat of the cooled medium, and then become low-pressure saturated (usually overheated) vapor itself, which is continuously sucked away by the compressor. In other words, the evaporator is a heat exchange device that absorbs heat (that is, outputs cold energy).

  

  Throttle element: Throttle element is one of the four main elements in the refrigeration system. Its main function is to throttle and reduce the pressure of high-pressure liquid refrigerant, ensure the pressure difference between condenser and evaporator, and make the refrigerant entering the evaporator absorb heat and evaporate at the required low pressure, thus achieving the purpose of refrigeration and cooling. Adjust the refrigerant flow into the evaporator to adapt to the load change of the evaporator and make the system run normally.

  

  Capillary: It is a very thin tube, usually with an inner diameter of 0.5 ~ 2.5 mm and a length of 1 ~ 5 m.. When the refrigerant flows in the tube, it is necessary to overcome the resistance in the tube, which naturally produces a certain pressure drop.

  

  Capillary characteristics: Because it is in the normally open state, when the compressor stops, the high and low pressure can be quickly balanced, which is conducive to the compressor starting again. Simple structure, convenient manufacture and low price. For the heat pump system, there is no import and export problem in the throttling process of refrigerant in capillary [this article source: refrigeration encyclopedia WeChat official account” target=_blank>. Using capillary refrigeration system, the performance of the unit is very sensitive to the refrigerant charge. When the operating conditions of the refrigeration system change, the capillary tube has poor ability to adjust the refrigerant flow. Due to the small inner diameter of capillary and long pipeline, it is easy to be blocked, so attention should be paid to the drying and cleaning of the system. Generally, a dry filter is set in front of the capillary to prevent clogging.

  

  Thermal expansion valve: the regulating valve that controls the liquid supply of evaporator, and it is also the throttle valve of refrigeration device. Thermal expansion valve uses the change of superheat of refrigerant at evaporator outlet to adjust the flow. According to different structures, it can be divided into internal balance type and external balance type.

  

  Disadvantages of thermal expansion valve: low control precision and limited adjustment range. The diaphragm deformation of valve body is limited, which makes the change range of valve needle opening smaller, so the adjustment range of flow is small. When large flow regulation is required, it cannot be met. The high-temperature gas at the place where the signal feedback has a lag evaporator must first heat the shell of the temperature sensor, which has a large thermal inertia, leading to the lag of the reaction.

  

  2

  

  Electronic expansion valve: the application of electronic expansion valve overcomes the shortcomings of thermal expansion valve and provides conditions for the intelligence of refrigeration device. The electric signal generated by adjusting parameters is mainly used to control the voltage or current applied to the expansion valve, so as to achieve the purpose of adjustment, so that the control system of the electronic expansion valve is complicated and the price is high.

  

  Electronic expansion valve classification:

  

  Electromagnetic electronic expansion valve;

  

  Electric electronic expansion valve.

  

  4. Auxiliary equipment of refrigeration system

  

  Oil separator: The high-pressure gas (gaseous working medium and lubricating oil) from the compressor enters the oil separator to separate the lubricating oil from the working medium gas and flows down along the inner wall of the cylinder. The working gas is led out of the oil separator from the central pipe through the porous baffle. The separated lubricating oil is concentrated in the lower part of the oil separator and can be discharged regularly, or the lubricating oil can be automatically returned to the crankcase of the compressor by using the ball valve.

  

  Drying filter: The function of drying filter is to absorb moisture in refrigeration system, prevent impurities in the system from passing through, and prevent the pipeline of refrigeration system from being blocked by ice and dirt. Because the most easily blocked part of the system is the capillary (or expansion valve), the drying filter is usually installed between the condenser and the capillary (or expansion valve).

  

  Liquid storage tank: During the operation of the refrigeration system, the circulating amount of refrigerant in the system will change due to the change of working conditions or the adjustment of refrigeration capacity. Setting the liquid storage tank can balance and stabilize the refrigerant circulation in the system by using the liquid storage capacity of the liquid storage tank, so that the refrigeration system can be in normal operation. In addition, when a component in the refrigeration system fails and needs to be dismantled and repaired, the system refrigerant can be recovered to the liquid storage tank through certain operation methods.

  

  The liquid storage tank is generally arranged between the condenser and the throttling element, so that the refrigerant liquid in the condenser can smoothly enter the liquid storage tank. The position of the liquid storage tank should be lower than that of the condenser.

  

  Electromagnetic four-way reversing valve: after the electromagnetic coil is energized, it changes the action direction of the valve block in the valve body and changes the flow direction of the refrigerant. So as to achieve the purpose of cooling or heating.

  

  three

  

  Solenoid valve: Solenoid valve is usually installed in front of the expansion valve to directly control the amount of refrigerant entering the evaporator. It can also be installed before the compressor unloading cylinder to control the unloading of the compressor cylinder.

  

  There are two kinds:

  

  Direct opening and closing solenoid valve;

  

  Indirect solenoid valve.

  

  One-way valve: The one-way valve is usually connected in parallel with the auxiliary capillary, and the two are connected in series with the main capillary. One-way valve is a tubular element with a movable spherical or hemispherical plug made of stainless steel or nylon. Combined with capillary tube, it can adapt to two different operating conditions of refrigeration and heating.

  

  5. Types and States of Refrigerant

  

  Air conditioning refrigerants mainly include R22, R410A and R32.

  

  R22 is a medium-temperature refrigerant, with the standard of -40.8 degrees, the solubility of water in R22 is very small, and it is mutually soluble with mineral oil, and R22 does not burn or explode, with little toxicity and strong permeability.

  

  R410A is a HFC refrigerant which is composed of R32 and R125 by 50% and 50% by mass. [This article comes from WeChat official account, a refrigeration encyclopedia” target=_blank>, which belongs to a near azeotrope, and its thermodynamic properties are very close to that of a single refrigerant. Compared with R22, R410A’s condensation pressure is increased by 1.6 times, and it is a high-pressure refrigerant, so it is necessary to improve the compression strength of the system.

  

  R32 is the abbreviation of difluoromethane, which is a kind of coolant with zero ozone loss potential. It is a gas at room temperature and a colorless and transparent liquid under its own pressure. It is soluble in oil and insoluble in water, and it is an energy-saving and carbon-reducing environment-friendly non-toxic refrigerant, but it is flammable and explosive!

  

  6. Refrigerant status

  

  Saturated refrigerant: Vapor-liquid conversion in saturated refrigerant is in transport equilibrium, and liquid and gas at this time are in saturation.

  

  There is a one-to-one correspondence between saturation temperature and saturation pressure, and the saturation pressure increases with the increase of saturation temperature, and one of them will change and the other will change accordingly. In the system, the refrigerant in the evaporator absorbs heat and the refrigerant in the condenser releases heat, where the refrigerant is saturated.

  

  Superheat: Under a certain pressure, the temperature of superheated steam exceeds the saturation temperature.

  

  Overheating: the temperature of refrigerant vapor in superheated refrigerant is higher than the saturation temperature under the corresponding saturation pressure, and the liquid refrigerant will overheat after evaporation. In the case of overheating, there is no one-to-one correspondence between the temperature and pressure of refrigerant gas.

  

  Near the outlet of the evaporator, the refrigerant continues to absorb heat after complete evaporation and becomes superheated refrigerant with a temperature higher than the saturation temperature. The refrigerant enters the compressor through the suction pipe in case of overheating.

  

  Supercooling: The liquid temperature of the supercooled refrigerant is lower than the saturation temperature at the corresponding saturation pressure, and supercooling will only occur when there is no steam in the fluid refrigerant. In the case of supercooling, there is no one-to-one correspondence between the temperature and pressure of refrigerant liquid.

  

  Between the outlet of the condenser and the throttle valve, the refrigerant may continue to cool exothermically and become supercooled after condensing into saturated liquid.

Kim Jong_un continues to guide military training of the Korean People_s Army

In order to grow rapidly, cnc milling services Do not hesitate to change the strategy and rearrange the products, so as to obtain unexpected results. https://www.ultirapid.com/services/cnc-machining/

Seoul, March 14. KCNA reported on the 14th that Kim Jong-un, General Secretary of the Workers ‘Party of Korea and Chairman of the State Councilor, directed the People’s Army Tank Corps Joint Force to conduct a confrontation training competition on the 13th. KCNA public reports show that Kim Jong-un has guided the People’s Army’s military training on site many times this month.

KCNA said that the confrontation training competition aims to test the tank soldiers ‘actual combat capabilities and be proficient in tactics. North Korea’s new main tank participated in the competition.

The report said that Kim Jong-un expressed great satisfaction with the combat performance, strike capabilities and mobility of the new main tank. He also boarded the new main tank and drove it himself.

The report said that Kim Jong-un emphasized the important role of tank soldiers in modern warfare and called for increased efforts to organize and hold practical training and training competitions to improve combat effectiveness.

According to previous reports from KCNA, Kim Jong-un also guided the People’s Army’s artillery training earlier this month, and visited training facilities and guided actual military training at important combat training bases in the western region.

Air conditioning 26℃ is the most reliable Should I turn off the air conditioner when

  01As we all know, solar heat and air conditioning The emergence of the market is worthy of many people’s attention, which has aroused the waves of the whole market. https://puremind.com/product-category/puremind-air-conditioner/solar-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.
