What is the difference between ceramic, high frequency and ordinary PCB boards?

Ceramic substrate is a kind of special PCB board with good thermal conductivity, insulation performance, and high dielectric constant. It is widely used in terminal products in the field of heat dissipation. Commonly used ceramic-based materials include aluminum oxide, aluminum nitride, zirconium oxide, ZTA, silicon nitride, silicon carbide, etc. FR circuit board refers to a circuit with epoxy glass fiber cloth as the main material. So, what is the difference between ceramic circuit board and ordinary PCB board

The difference between ceramic substrate and PCB board

Different materials. Ceramic substrate is an inorganic material, and the core is aluminum oxide or aluminum nitride; ordinary PCB board uses FR4 glass fiber board, which is an organic material. Ordinary PCB board can be laminated in multiple layers. LTCC is the mainstream of ceramic multilayer circuit board. The ceramic multilayer process currently being developed by Hitech Circuits Co., Ltd. is different from the traditional method. It uses magnetron sputtering technology to grow a layer of ceramic medium on the ceramic circuit board that has been metallized, and then re-metallizes this layer of medium to make the second layer of circuit.

b. The performance and application of ceramic substrates are different. The thermal conductivity of ceramic substrates far exceeds that of ordinary PCB boards. The thermal conductivity of alumina ceramics is ≧25W(m·K), and the thermal conductivity of aluminum nitride ceramics is ≧170W(m·K). They are used in industries with large heat dissipation requirements, such as high-power LED lighting, high-power modules, high-frequency communications, and track power supplies. The thermal expansion coefficient of ceramic substrates is more compatible with silicon wafers, and the product stability is higher. Ordinary PCB boards are widely used, mostly in private commercial products.

The difference between ceramic substrates and high-frequency boards

Different materials. Ceramic substrates are made of aluminum oxide or aluminum nitride, while high-frequency boards are mostly made of Rogers, Yalong, polytetrafluoroethylene, etc., with low dielectric constants and fast high-frequency communication speeds.

Different performance. Ceramic substrates are widely used in cooling sheets and systems, high-power modules, automotive electronics and other fields. High-frequency PCB boards are mainly used in high-frequency communications, aviation, high-end consumer electronics, etc.

3. In the field of high-frequency communications involving heat dissipation requirements, ceramic substrates are usually required to be combined with high-frequency PCB boards, such as high-frequency ceramic PCBs.

Better Neutron Mirrors Can Reveal the Inner Secrets of Matter - Technology Org

Better Neutron Mirrors Can Reveal the Inner Secrets of Matter - Technology Org

Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the ESS, which is being built outside Lund.

The improved mirror has been developed by researchers at Linköping University by coating a silicon plate with extremely thin layers of iron and silicon mixed with boron carbide. Their study has been published in the journal Science Advances.

“Instead of increasing the power on the neutron source, which is extremely expensive, it’s better to focus on improving optics,” says Fredrik Eriksson, researcher at the Thin Film Physics Division at Linköping University.

Together with protons, neutrons form atomic nuclei. Depending on the number of neutrons in a nucleus, the properties of the element can differ. In addition, neutrons can also be used to analyse different materials at a very detailed level. This method is called neutron scattering.

Advanced materials science

Such measurements are carried out at special neutron research laboratories called neutron sources. One such laboratory, the European Spallation Source, or ESS, is now being built outside Lund. This is an investment of EUR 2 billion.

Fredrik Eriksson explain how the measurements of reflectivity works. Image credit: Olov Planthaber/Linköping University

The ESS and other neutron sources can be compared to advanced microscopes that allow scientists to investigate various materials and their properties down to the atomic level. They are used in everything from studying atomic structures, material dynamics and magnetism, to the functions of proteins.

It requires enormous amounts of energy for the neutrons to be released from the atomic nuclei. When the neutrons are released in the neutron source, they must be captured and directed toward their target, that is, the material to be investigated. Special mirrors are used to direct and polarise the neutrons. These are known as neutron optics.

Polarising optics

Although the ESS will have the world’s most powerful neutron source, the number of neutrons available in the experiments will be limited. To increase the number of neutrons that reach the instruments, improved polarising optics are required. This is something researchers from Linköping University have now achieved by improving neutron optics on several important points to increase efficiency.

“Our mirrors have better reflectance, which increases the number of neutrons that reach their target. The mirror can also polarise the neutrons into the same spin much better, which is important for polarised experiments”, says Anton Zubayer, doctoral student at the Department of Physics, Chemistry and Biology and lead author of the article published in Science Advances.

He continues:

“Also, as this no longer requires a large magnet, the mirror can be placed closer to the samples or other sensitive equipment without affecting the samples themselves, which in turn enables new types of experiments. In addition, we have also reduced the diffuse scattering, which means that we can reduce background noise in the measurements.”

High reflectivity

The mirrors are manufactured on a silicon substrate. Through a process called magnetron sputtering, it is possible to coat the substrate with selected elements. This process makes it possible to coat it with several thin films on top of each other, i.e. a multilayer film. In this case, iron and silicon films are used, mixed with isotopic enriched boron carbide. If the layer thicknesses are of the same order of magnitude as the neutron wavelength, and the interface between the layers is very smooth, the neutrons can exit the mirror in phase with each other, giving a high reflectivity.

Fredrik Eriksson believes that every neutron is precious and every small improvement in the efficiency of the neutron optics is valuable to improve the experiments.

“By increasing the number of neutrons and also reflecting higher neutron energies, opportunities are opened for pioneering experiments and groundbreaking discoveries across disciplines including physics, chemistry, biology and medicine,” says Fredrik Eriksson.

The study was funded by the Swedish Research Council, the Royal Swedish Academy of Engineering Sciences, the Royal Swedish Academy of Sciences, the Hans Werthén Foundation, the Knut and Alice Wallenberg Foundation, the Swedish Foundation for Strategic Research, and through the Swedish Government’s strategic investment in new functional materials, AFM, at Linköping University.

Facts: Neutron analysis makes use of the neutrons’ ability to behave both as a wave and as a particle. These neutrons, in turn, can have two different spins. It is important mainly for magnetic studies to be able to use polarised neutrons, i.e. neutrons with only one specific spin.

Butterfly-inspired films create vibrant colors while passively cooling objects

The new films, which don’t absorb any light, could be used on the outside of buildings, vehicles and equipment to reduce the energy needed for cooling while preserving vivid color properties. “In buildings, large amounts of energy are used for cooling and ventilation, and running the air conditioner in electric cars can reduce the driving range by more than half,” said research team leader Wanlin Wang from Shenzhen University in China. “Our cooling films could help advance energy sustainability and carbon neutrality.” In Optica, Optica Publishing Group’s journal for high-impact research, the researchers show that the films they developed lower the temperature of colorful objects to about 2 °C below the ambient temperature. They also found that when left outside all day, the blue version of the films was approximately 26°C cooler than traditional blue car paint. This represents an annual energy savings of approximately 1377 MJ/m2 per year. “With our new films, excellent cooling performance can be achieved, no matter the desired color, saturation or brightness,” said Wang. “They could even be used on textiles to create clothes of any color that are comfortable in hot temperatures.” Inspired by nature A car with blue paint appears blue because it absorbs yellow light and reflects blue light. The large amount of light that is absorbed heats the car. Morpho butterflies, however, produce their highly saturated blue color based on the nanostructure of their wings. The design of the cooling nanofilm mimics these structures to produce vibrant colors that don’t absorb light like traditional paint. advertisement To create their Morpho-inspired nanofilms, the researchers placed a disordered material (rough frosted glass) under a multilayer material made of titanium dioxide and aluminum dioxide. They then placed this structure on a silver layer that reflects all light, thus preventing the absorption of solar radiation and the heating associated with that absorption. The film’s color is determined by how components within its multilayered structure reflect light. To create blue, for example, the multilayer material is designed to reflect yellow light in a very narrow range of angles while the disordered structure diffuses the blue light across a broad area. Although this type of passive photonic thermal management has been accomplished before, it has only been used with white or clear objects because it is difficult to maintain a wide viewing angle and high color saturation. Passive cooling of colorful objects “Thanks to the layered structure we developed, we were able to extend the passive cooling method from colorless objects to colorful ones while preserving color performance,” said Wang. “In other words, our blue film looks blue across a large range of viewing angles and doesn’t heat up because it reflects all the light. In addition, high saturation and brightness can be achieved by optimizing the structure.” To test the new technology, the researchers created blue, yellow and colorless films, which they placed outdoors at Shenzhen University, on surfaces such as roofs, cars, cloth and cell phones, from 9 a.m. to 4 p.m. in both winter and summer. Using thermocouple sensors and infrared cameras to measure temperature, they found that the cooling films were more than about 15 ? cooler than the surfaces they were placed on in the winter and about 35 ? cooler in the summer. The researchers point out that replacing the silver film with an aluminum film would make the films less expensive and manufacturable by a scalable fabrication method such as electron beam evaporation and magnetron sputtering. Now that they have demonstrated the cooling and color performance of the films, the researchers plan to study and optimize other properties such as mechanical and chemical robustness.

Obninsk Research and Production Enterprise, a subsidiary of Rostec, has developed a new Su-57 fighter canopy glass to provide better stealth resources.

The design solution allows you to improve by 20% the characteristics of the cockpit windows of aviation complexes, including reducing the visibility of combat vehicles in radar range, Rostec said in a statement.

The special properties of stealth glass are given by the thinnest films of metals and metal oxides deposited on its surface by sputtering of magnetron in a vacuum installation. The configuration update increased the peak spray values of the magnetron by more than three times, making it possible to depose films with a much lower surface resistance. The engineering solution significantly improves the quality of the coating applied to aircraft glazing products in series, thanks to which the cockpit canopy receives improved optical characteristics and low radar visibility. These factors increase the combat potential and survivability of "stealth birds".

"Today, the samples produced with updated equipment have proven their characteristics calculated during measurements and tests. The new technology will be used to create structural optics for advanced aviation systems. This will reduce the radar signature of the aircraft and increase its combat capabilities," Rostec Vice President Vladimir Artyakov said, according to the press office.

ONPP Technologies has unique experience in the independent development and mass production of structural optics products with multifunctional thin film coatings applied. Today, the engineering and software solutions implemented by the company's experts allow you to create metal-optical structures composed of 200 or more layers, each with a thickness of 0.25–0.3 nm.
