Ceramic Substrate Series - The main applications of alumina ceramic substrates

Ceramic substrates are widely used in various fields such as power electronics, electronic packaging, hybrid microelectronics, and multi-chip modules due to their excellent thermal conductivity and airCeramic Substrates tightness. Among them, alumina ceramic is the most commonly used ceramic substrate material, favored for its overall good performance. The advantages of alumina ceramic substrates include excellent insulation performance, exceptional high-temperature resistance, high strength and hardness, outstanding chemical stability, and good processability. They effectively isolate circuits, withstand high temperatures, resist chemical corrosion, and meet complex processing and high-precision dimensional requirements. The main applications of alumina ceramic substrates are as follows:Get more news about Alumina Ceramic Substrate,you can vist our website!
Alumina ceramic substrates for resistors offer advantages such as small size, light weight, low coefficient of thermal expansion, high reliability, high thermal conductivity, and density. They greatly improve the reliability and wiring density of circuits, making them an ideal carrier material for chip resistor components.

Hybrid integrated circuits involve packaging multiple components, with at least one of them being active. These complex circuits are created by installing the components on metal conductor-insulator sheets produced through thick-film or thin-film processes. The substrate provides mechanical support for the circuit, serves as the deposition site for dielectric and resistance materials, and offers mechanical support for all passive and active chip elements. Alumina, beryllia, silicon dioxide, and aluminum nitride are commonly used substrates for hybrid integrated circuits. However, considering cost and performance, alumina substrates with smooth surfaces are widely used. The quality and grades of alumina substrates vary depending on the alumina content. Common options include 99.6% alumina for thin-film circuits and 96% alumina for thick-film circuits. Multilayer co-fired alumina ceramics generally use alumina green sheets with alumina content ranging from 90% to 95% as the base material.

Substrates for power devices

For packaging power electronic devices, substrates need to provide not only basic wiring (interconnection) functions but also high thermal conductivity, insulation, heat resistance, pressure resistance, and thermal matching capabilities. Metal-ceramic substrates such as DBC (Direct Bonded Copper) and DPC (Direct Plated Copper) have superior performance in terms of thermal conductivity, insulation, pressure resistance, and heat resistance. They have become the preferred materials for power device packaging and are gradually gaining market recognition. The most common substrate material for device packaging is alumina (Al2O3), typically with an alumina content of 96%. Alumina substrates are mature in terms of technology and have low cost.

Alumina ceramic substrates for LEDs

High-power LED heat dissipation substrates are primarily composed of ceramic substrates. The most commonly used high-power ceramic substrates in the market are LTCC (Low-Temperature Co-Fired Ceramic) and DPC (Direct Plated Copper). Ceramic materials such as alumina and aluminum nitride are used. Alumina ceramic substrates for LEDs possess high heat dissipation and air tightness, which improve the LED's luminous efficiency and lifespan. Their excellent air tightness also provides high weather resistance, allowing them to be used in various environments.

The Best Motorized Blinds for Your Home or Studio Space

SMART BLINDS USED to be an overtly expensive luxury, with a big, clunky remote and needing an installation company to come over and set it up. But now, you can buy smart, motorized blinds off-the-shelf (or online) to install yourself – even customized ones. No matter if you’ve got pull-down shades or tilt-blinds, you can either purchase them to install, or snag add-ons to make the existing blinds in your home “smart.” Ready to control your blinds via your phone or preferred virtual assistant? Read on for our shopping guide.Get more news about motorized blinds,you can vist our website!

Smart Blinds Buying Guide
Here’s what you need to know about how the addition of motorized curtains or smart blinds to any smart home work, the different types you need to know, as well as features you need to consider before purchasing them.

Tubular motor: This is typically the most common, most affordable option. It’s a basic motor that can work with a remote, is relatively quiet, and adds the ability to roll up and down existing shades without needing to buy whole new blinds. One of the big issues you’ll notice right off is that these often need to be plugged directly into a wall outlet, and there aren’t commonly outlets around where shades go. Plus even with an extension cable, you’ve still got unsightly power cables hanging down all over the room (which also might be a safety hazard). They do have the ability to connect to WiFi, but usually can handle only a few commands.
Solar/Battery: This one makes way more sense if you’re connecting to WiFi, as you’ll need to be consistently hooked up to a power source, and solar is a pretty good one since it’s right next to a window. They give you local control, wirelessly, and a single remote also has the ability to control all the shades in the house too, making it really convenient for bedtime and mornings. The downside though, is that these are typically more expensive, and with each as its own individual unit, you’ll need one per window, which can really add up.

Add-on: This one’s the best option for renters who can’t change what’s already there, or people who don’t want to mess with their current setup too much. An add-on piece is pretty simple, with a motor inside that can twist open blinds or roll up shades. They also work great with apps and integrate well into smart-home systems like Alexa and Google Home, though Apple HomeKit wasn’t as common (but that’s changing).

Don’t get too wrapped up in the smartness of it all and forget about the quality of the shade itself. These still should be able to block out light (if that’s what you’re going for) and made from a strong, often waterproof, material. Measure your windows too – most regular windows are going to be about 34-36 inches wide, but if you’ve got odd-sized ones, you may need to do some DIY resizing to make it fit.
What Are the Best Smart Blinds?
Here are the top motorized curtains and smart blinds to add to your living room and around your home this season, plus one device that’ll let you turn your curtains into a “smarter” version.

1. SwitchBot Blind Tilt Motorized Blinds

This bot has the power to push open curtains that weigh up to 17 pounds, and through the app you can set an opening/closing schedule based on time or the amount of daylight. Give it a slight pull, and it will do the rest, or control it with the remote (sold separately) as well. The overall operating system is simple to get the hang of, and even easier to install.

What makes electrical cables suitable for outdoor use?

When selecting the best electrical cables suitable for outdoor use, there are a few factors to consider. This article will look at the characteristics that make electrical cables appropriate for outdoor use, as well as some of the aspects to consider when purchasing. The following factors make electrical cables suitable for outdoor use:Get more news about Electric Cable,you can vist our website!

On the wires, the type of insulation used.
Electrical cables are typically made with three types of insulation: PVC, polyethylene, and cross-linked polyethylene. PVC is the most common type of insulation, as it is durable and resistant to sunlight and moisture.

However, PVC is not as flexible as polyethylene, making it less suitable for use in cold weather. Polyethylene is a more flexible alternative that is also resistant to moisture and chemicals. Cross-linked polyethylene is the most expensive type of insulation, but it is also the most durable and can withstand extreme temperatures.

When choosing an electrical cable for outdoor use, it is important to consider the environment in which it will be used. For example, if the cable will be exposed to sunlight, it is important to choose a cable with UV-resistant insulation. If the cable will be used in a wet or humid environment, it is important to choose a cable with water-resistant insulation.

The type of jacket or covering protecting the wires.
Electrical cables are used in a variety of settings, both indoors and out. While most applications don't require special considerations, those that will be exposed to the elements require a different type of cable. Outdoor electrical cables must withstand exposure to sunlight, moisture, and extreme temperatures.

They also need to be durable enough to resist abrasion, chewing, and other forms of damage. The type of jacket or covering protecting the wires makes electrical cables suitable for outdoor use. The most common materials used for outdoor cables are polyvinyl chloride (PVC) and polyethylene (PE).

PVC is more flexible than PE, making it easier to route through tight spaces. However, PE is more resistant to sunlight and chemicals, making it the better choice for buried applications. When selecting an outdoor electrical cable, it's important to consider the environment in which it will be used. This will ensure that the cable can withstand the elements and continue to perform as expected.
The gauge or thickness of the wire.
Most electrical cables are made of copper or aluminium wire, which is wrapped in plastic insulation. The gauge or thickness of the wire makes electrical cables suitable for outdoor use. In general, the thicker the wire, the lower the gauge number. AWG stands for American Wire Gauge, which measures the thickness of wire. As wire thickness increases, AWG decreases.The thicker the wire, the lower the AWG number.

For example, AWG 10 is thicker than AWG 12. Electrical cables are typically made with either solid or stranded wire. Stranded wire is made up of a group of thin wires that are twisted together to form a larger cable. Stranded wire is more flexible than solid wire and is less likely to break if it is bent.

Electrical cables are also rated by their voltage and amperage capacity. Voltage is a measure of the difference in electrical potential between two points, and amperage is a measure of the flow of electric current. Electrical cables that are used outdoors must be able to withstand higher voltages and amperages than those that are used indoors.

Outdoors, electrical cables are also exposed to weather conditions that can damage the insulation, so they must be able to withstand UV radiation, extreme temperatures, and moisture.

AI drone 'kills' human operator during 'simulation

It turned on its operator to stop it from interfering with its mission, said Air Force Colonel Tucker "Cinco" Hamilton, during a Future Combat Air & Space Capabilities summit in London.Get more news about Drone Simulator Company,you can vist our website!

"We were training it in simulation to identify and target a SAM [surface-to-air missile] threat. And then the operator would say yes, kill that threat," he said.

"The system started realising that while they did identify the threat at times the human operator would tell it not to kill that threat, but it got its points by killing that threat. So what did it do? It killed the operator. It killed the operator because that person was keeping it from accomplishing its objective."He went on: "We trained the system - 'Hey don't kill the operator - that's bad. You're gonna lose points if you do that'. So what does it start doing? It starts destroying the communication tower that the operator uses to communicate with the drone to stop it from killing the target."

"You can't have a conversation about artificial intelligence, intelligence, machine learning, autonomy if you're not going to talk about ethics and AI," he added.His remarks were published in a blog post by writers for the Royal Aeronautical Society, which hosted the two-day summit last month.

In a statement to Insider, the US Air Force denied any such virtual test took place.The Department of the Air Force has not conducted any such AI-drone simulations and remains committed to ethical and responsible use of AI technology," spokesperson Ann Stefanek said.

"It appears the colonel's comments were taken out of context and were meant to be anecdotal."While artificial intelligence (AI) can perform life-saving tasks, such as algorithms analysing medical images like X-rays, scans and ultrasounds, its rapid rise of has raised concerns it could progress to the point where it surpasses human intelligence and will pay no attention to people.

Sam Altman, chief executive of OpenAI - the company that created ChatGPT and GPT4, one of the world's largest and most powerful language AIs - admitted to the US Senate last month that AI could "cause significant harm to the world".

New Battery Storage Capacity

When you predict the future, one thing is almost guaranteed — that you will be wrong. Nonetheless, people want to know what the future holds, and some people have methods or insights to get closer to that future than others. The electric vehicle revolution depends on one thing more than any other — the scaling up of battery production — and this is where there’s quite a bit of uncertainty, so take any forecasts with a grain of salt. That said, this is such a big matter that we like to explore any decent looking forecasts we find, and we’ve got another one to look at today.Get more news about Battery Energy Storage,you can vist our website!

This battery energy storage forecast comes from Rystad Energy. The prediction is that energy storage installations will surpass 400 GWh a year in 2030, which would be 10 times more than current annual installation capacity. Today’s energy storage installations may seem minimal compared to what they are expected to be in 2030, but they have been growing fast already. New energy storage capacity in 2022 was 60% higher than in the year before. 43 GWh were added last year. This year, 74 GWh are expected to be added, which would be 72% more than last year.
The growing energy storage market is largely being attributed to dropping battery storage costs as well as “incentives in North America, governmental funding programs in Europe, coupled with robust renewable capacity expansion in mainland China.”

Naturally, GWh concerns energy storage capacity, while GW represents power capacity. While Rystad Energy projects energy storage capacity rising above 400 GWh by 2030, they expect power capacity to rise to 110 GW by then. That is “almost equivalent to the peak residential power consumption for France and Germany combined,” the company adds.
Regarding the expected growth in North America and Europe, Rystad Energy writes: “Government policies are playing an important role in incentivizing investments and capacity expansion. Last year’s US Inflation Reduction Act has catalyzed renewable and clean tech expansion, boosting expected solar and onshore wind capacity by 40% and expecting to add more than 20 GW battery capacity compared to before the Act. As result, the US battery capacity will exceed 130 GW by 2030.

“The European Green Deal Industrial Plan aims to accelerate the transition to a sustainable and low-carbon industrial sector in Europe, and gradually supports the BESS development in addition to the local fundings for BESS developers – for example, a £32 million energy storage funding program in the UK. China is committed to peaking its emissions by 2030 and sees battery developments as a steppingstone to achieving that goal. The country’s clean energy development will accelerate in the coming years, increasing the share of renewables in its power mix.”

Liquid-filled optical fiber designed for more robust data transmission

Although optical fibers are highly effective at data transmission, they're also relatively brittle. An experimental new type of optical fiber addresses that limitation, by incorporating a core made of liquid glycerol.Get more news about Optical Cable Filling,you can vist our website!

Ordinarily, optical fibers are made of either solid glass or a solid transparent plastic. The former is able to carry light pulses over a longer distance, but will break fairly easily if bent or stretched. The latter – which is useful over shorter distances, such as within buildings – stands up better to bending, but stretching it will still cause it to break.
Seeking an alternative, researchers at Switzerland's Empa institute have developed an optical fiber consisting of a continuous liquid glycerol core contained within a transparent fluoropolymer sheath.

"The two components of the fiber must pass through our spinneret together under high pressure and at 200 to 300 degrees Celsius [392 to 572 ºF]," says the lead scientist, Dr. Rudolf Hufenus. "So we need a liquid with a suitable refractive index for functionality and with the lowest possible vapor pressure to produce the fiber."

The resulting fiber's ability to transmit data in the form of light pulses is approximately equal to that of solid plastic optical fibers, but it has much higher tensile strength – in other words, it's significantly better at withstanding stretching.
As an added bonus, if the fiber is being stretched, its color will change. This is due to the fact that the same amount of glycerol will still be present within the fiber, but because the liquid is being spread out over a longer distance, red dye particles within it will be farther apart from one another. As a result, the color of the light that's emitted through the sheath will subtly change. That color-change could be measured using an optical sensor, letting users know that the fiber – and thus a device incorporating it – is lengthening or being subjected to a tensile load.

All of that being said, won't the glycerol just leak out when the fiber is cut to the desired length? "Under normal conditions, the liquid core is kept inside the fiber due to capillary forces; however, when a pressure is applied on the fiber, the liquid can be pressed out of the fiber tip," Hufenus tells us. "This can be prevented by sealing the fiber end with a hot blade."

Gaskets - How do they work and why do we need them?

The scope of this presentation is to present basic information and understanding of the ASME code for the design of pressure vessels for the chemical and process industry as applicable in the United States and most of North and South America.Get more news about Flange Metallic Gasket,you can vist our website!

Gaskets – How do they work and why do we need them?
If you are a fabricator, one of the last things on your list is ordering the gaskets. If you are an Engineer, the last thing on your list is specifying gaskets. If you are an owner and you hare having a problem sealing flanges, the number ONE thing on your mind is gaskets.

Many times, they look like a sheet of paper. They can have metal or graphite rings. They can be carbon steel or stainless steel. They can be big or small. But if you don’t have them, it is a tough life in the refinery, chemical plant or in the field.

The cost of leaky joints in industry today is staggering. Out-of-pocket costs run into billions of dollars annually in lost production, waste of energy, loss of product and, most recently, impact on the environment. These problems are increasing, not decreasing. It behooves all of us to consolidate our knowledge and experience to solve or at least minimize these problems. Too often we find insufficient time and attention has been given to:

Selection of the optimum gasket material required to solve a particular sealing problem.
We will endeavor to outline those areas we believe to be essential in a properly designed, installed and maintained gasketed joint.

We believe most people involved with the design, installation, and maintenance of gasketed joints realize that no such thing as “zero” leakage can be achieved. Whether or not a joint is “tight” depends on the sophistication of the methods used to measure leakage. In certain applications the degree of leakage may be perfectly acceptable if one drop of water per minute is noted at the gasketed joint. Another requirement is that no bubbles would be observed if the gasketed joint was subjected to an air or gas test underwater. A still more stringent inspection would require passing a mass spectrometer test. The rigidity of any test method would be determined by:
Care in these areas will ensure that the best technology and planning goes into the total package and will minimize operating costs, pollution of the environment and hazards to employees and the general public.

Why Gaskets are Used
Gaskets are used to create a static seal between two stationary members of a mechanical assembly and to maintain that seal under operating conditions, which may vary dependent upon changes in pressures and temperatures. If it were possible to have perfectly mated flanges and if it were possible to maintain an intimate contact of these perfectly mated flanges throughout the extremes of operating conditions, a gasket would not be required.
As a consequence, relatively inexpensive gaskets are used to provide the sealing element in these mechanical assemblies. In most cases, the gasket provides a seal by utilizing external forces to flow the gasket material into the imperfections between the mating surfaces. It follows then that in a properly designed gasket closure, three major considerations must be taken into account in order for a satisfactory seal to be achieved.

I was mightily impressed with the amount of design thought that went into Wyrmwood's Modular Gaming Table. The dining table can be easily transformed into a tabletop gaming center or crafting workstation, with a seemingly endless variety of useful accessories that slide into magnetic slots.

I was also in awe of their massive Kickstarter haul for the project (close to $2 million at press time) and their claim that they could produce 100 of the seemingly complicated tables each week. And with the release of this video below, I now see how the latter is possible.

Wyrmwood has two production facilities—one for fabrication, the other for assembly—manned by craftspeople using incredible automated woodworking machines. And while the machines themselves are blindingly cool, what really shines through is that the MGT, as well as all of the processes at the factory, were very carefully designed for production. It's not often that I can sit through a 17-minute video and be impressed by segment after segment, from wood sorting right down to the final packaging:

Indian soldiers get light weight Bullet Proof Helmets

The Indian Army soldiers are now protected against 9 mm carbine bullet strikes with the new `Made in India’ Bullet Proof Helmets. The new helmets were the first major contract for modern composite helmets placed under Make in India initiative, and the contract between Kanpur based MKU Ltd and the Ministry of Defence was signed during the tenure of the then defence minister Late Manohar Parrikkar in 2016. The contract was for 1, 58.279 Bullet Proof Helmets (BPH).Get more news about Bulletproof Helmet,you can vist our website!

Vaibhav Gupta, Director and Head of Domestic Operations, has confirmed to Financial Express Online on Friday that “Contract has successfully been completed by the company earlier this year in April. And the helmets supplied are already in use by the Indian Army in critical operation areas and are also being used by the Indian Navy.”
“Around 55,000 of the 1.58 lakh BPHs are equipped with communication systems to be used by commanders. And these have been completely designed and manufactured in India by MKU,” Vaibhav Gupta added.

According to him the helmets were selected after undergoing extensive user and ballistic trials by the Indian Army in all types of terrains and firing trials. “Our ongoing and continued investment in R&D has facilitated major breakthroughs.”

“We at MKU have successfully executed export orders for helmets from Chile, Philippines, Singapore, Egypt and Nepal in the recent past,” he says.

In stiff competition from the Chinese company, the export order from Nepal was the first for an Indian company.According to the company officials the new Bullet Proof Helmets will be replacing the ‘bulletproof patka’ that the soldiers in the Indian Army have been using since the 1990s. This was a sheet of armoured steel which was wrapped in canvas and was circular in shape.

The new helmets are capable of protecting the soldier from the 9 mm carbine bullets which flies at twice the speed of sound, and the kinetic energy it delivers causes huge trauma on those who are wearing body armour and helmets.

The new technologies used in these light weight helmets will ensure that the soldiers are protected against the impact of such bullets.

The Indian Army has got these new hi-tech helmets after over two decades. The delivery of the order was completed over a span of three years.
In the 90s when the Army was deployed to fight insurgency in J & K, the soldiers were equipped with 1974 model fiberglass helmets. These were not adequate enough to protect the soldiers against flying bullets and splinters.

The `Patka’ like helmets designed by former Major General VK Datta in the early 1990s, was the low cost option used for protecting the soldier wearing it. It was not enough in preventing injuries due to blunt trauma and the top portion was open.

She altered lottery tickets and kept the winnings

When a Florida Lottery vendor noticed “micro-scratches” on $50 and $10 scratch-off tickets for sale at a convenience store last June, the discovery led investigators to a cashier clerk arrested in a scheme to steal winning tickets and pocket the cash.Get more news about custom lottery tickets,you can vist our website!

That’s according to a criminal investigation launched June 14, 2022 by special agents with the Florida Department of Lottery into Christine Nicole Fenton-Gilbert, 39, who was formerly employed at the Rebel Store in Jensen Beach.

In court Monday, Fenton-Gilbert was ordered to 18 months in prison on charges related to altering more than a dozen scratch-off Florida Lottery tickets, including one worth $20,000 that she admitted buying because she knew it was a winner.
Circuit Judge William Roby found Fenton-Gilbert guilty of 16 counts of forging lottery tickets and imposed a prison term of 18 months on each count, all to be served at the same time.

Roby also ordered her to serve 13 years of probation for one count of grand theft and to pay $20,000 to the Florida Lottery and $1,196 to the Rebel Store in restitution.Fenton-Gilbert had faced a maximum term of 95 years in prison before she struck a deal with the state on Feb. 9, requiring she plead no contest to 17 felonies. Prosecutors then dropped one count of organized fraud, records show.

Fenton-Gilbert said nothing before she surrendered to deputies. She had been free in lieu of $115,000 bond, according to court filings.After court, Assistant State Attorney David Lustgarten called Fenton-Gilbert’s sentence “a fair resolution” and said the plea terms noted how she cooperated with law enforcement and had little criminal history.

“The plea deal involved a sentence which was more than the minimum,” Lustgarten said. “In a nutshell, she's going to prison on her first felonies and that doesn't happen too often.”
