What is halogen free PCB(HF PCB) substrate
According to jpca-es-01-2003 standard: PCB CCL with chlorine (C1) and bromine (BR) content less than 0.09% wt (weight ratio) is defined as halogen-free copper clad laminate. (at the same time, total CI + br ≤ 0.15% [1500ppm])To get more news about Halogen Free PCB, you can visit pcbmake official website.
2. Why should halogen be banned in PCB
Halogen refers to the halogen group elements in the periodic table of chemical elements, including fluorine (f), chlorine (CL), bromine (BR) and iodine (1). At present, flame retardant FR4 substrate, FR4, CEM-3, etc., flame retardant is mostly brominated epoxy resin. In brominated epoxy resin, tetrabromobisphenol A, polybrominated biphenyl, polymerized polybrominated diphenyl ether and polybrominated diphenyl ether are the main blocking fuel for copper clad laminates, which are low cost and compatible with epoxy resin. However, studies by relevant institutions have shown that halogen containing flame retardant materials (polybrominated biphenyl PBB: polybrominated diphenyl ether PBDE) will emit dioxin dioxin (TCDD) and benzfuran (benzfuran) when they are burned on fire. They have a large amount of smoke, bad smell, high toxic gases, carcinogenic, and can not be discharged after ingestion, which is not environmentally friendly and affects human health. Therefore, the EU initiated a ban on PBB and PBDE as flame retardants in electronic information products. According to the same document issued by the Ministry of information industry of China, the electronic information products put into the market shall not contain lead, mercury, hexavalent chromium, polybrominated biphenyls or polybrominated diphenyl ether. Six substances, such as PBB and PBDE, are prohibited by EU law. It is understood that PBB and PBDE are basically not used in the copper clad laminate industry. Bromine flame retardant materials other than PBB and PBDE are mostly used, such as tetrabromobisphenol A, dibromophenol, etc., whose chemical formula is cishizobr4. There are no laws and regulations on this kind of copper clad laminate containing bromine as flame retardant. However, this kind of copper clad laminate containing bromine will release a large amount of toxic gas (brominated type) during combustion or electrical fire. When PCB is used for hot air leveling and component welding, the board will also release a small amount of hydrogen bromide due to the influence of high temperature (> 200); whether dioxins will also be produced is still under evaluation. Therefore, FR4 board containing tetrabromobisphenol A flame retardant is not prohibited by law and can be used, but can not be called halogen free PCB board.
3. Principle of halogen free PCB(HF PCB) substrate
At present, most of halogen free PCB materials are mainly phosphorus and phosphorus nitrogen series. When the phosphorus containing resin is burned, it will decompose into metapolyphosphoric acid, which has strong dehydration property, forms carbonization film on the surface of polymer resin, insulates the burning surface of resin from contacting with air, extinguishes the fire and achieves flame retardant effect. The high polymer resin containing phosphorus and nitrogen compounds produces non combustible gas during combustion, which helps the resin system to be flame retardant.

ADVANCED AND NON-STANDARD PCB MANUFACTURING CAPABILITIES
There was a time when the PCB manufacturing industry included a fair number of bucket shops, so called because much of their processing was done in small portable tubs filled with etchants, solvents, and other mysterious solutions. They cranked out very basic, low-cost, low-complexity PCBs, using equipment and methods that were questionable at best. Their business and environmental practices were often similarly questionable.To get more news about Cavity PCB, you can visit pcbmake official website.
The good news for circuit board customers is that bucket shops are a thing of the past. Those fabricators who remain viable can execute all basic production steps repeatedly, with a low likelihood of scrap, on printed circuit boards that would have been considered insanely complex just a few years ago. Still, there are higher-end processes that not every supplier is equipped to do.
It is important to be sure that the circuit board you are about to order is going to a PCB manufacturer that can handle several difficult design features simultaneously. Otherwise your order could be scrapped, or it could show up on your dock with undetected manufacturing errors that will complicate assembly, installation, or function. The following post explains what some of the more difficult processes are, so that you can be sure to identify an appropriate fabricator for your order.
Controlled Impedance
There was a time when many small to medium shops were not able to support impedance testing, but those days have passed. Controlled impedance PCB designs are now so common that the ability to check impedance results has become a basic requirement for remaining in business. It is now possible to have your order tested no matter where it is built. If you supply the necessary information at the beginning of your project, your boards should arrive with a report of the results. Expect to pay a small up charge per PCB. The up charge covers the cost of setting up and performing the test, which is not done on the same machine as the one used for checking basic continuity. It also covers the potential small increase in fallout for boards which fail impedance testing, despite being free of other manufacturing errors.
Wraparound Edge Plating
Occasionally, it is desirable to form a connection by wrapping the plating around the PCB edge, rather than by means of a standard via hole, so that the edge can serve as a conductor. The fabricator accomplishes the wrap plate by performing an extra primary routing operation immediately after drilling. The purpose of this routing step is to expose the PCB sidewall so that it can be coated with electroless base copper (or an equivalent) in the same manner and at the same time as it is applied to the drilled holes.
After the photographic circuit image has been applied and developed, the electroless layer provides a conductive surface onto which the thicker, more durable electrolytic copper can adhere. If the artwork includes a pad or other shape that defines the routed area as a plated feature, the electrolytic copper plating will coat the routed channel to form the desired connection. While this process adds steps, plus a small amount of complication in the planning of array setups and machining processes, it is not overly difficult to arrive at a good result.

It was a shocking, unexpected but perfectly reasonable answer.Who else except the queen of the Imperium could boast the capabilities to crush Li Lingfeng the moment they met and forced him to escape in desperation?
Li Yao was full of curiosity for the queen of the Imperium who was suspected to be his foster father’s “lover” in the past.
He knew that ever since Wuying Qi, a man of the time, rose unstoppably a thousand years ago and established the Imperium of True Human Beings, there had never been an emperor as dominating as “Blackstar the Great” in the Imperium.
The emperors that followed were worse and worse. Also, because of the natural restraints of the vastness of the universe, the imperial authority had been collapsing the whole time.
Today, the emperor had already been marginalized, and the warlords were rising and almost dissecting the Imperium.The emperors had to be elected by the four “Kurfürsten”. Naturally, they were under the control of the powerful warlords as puppets.
Li Linghai, as the queen of the Imperium, was naturally a tool for the four Kurfürst families to monitor and control the emperor.However, from Li Lingfeng’s lines, it was not hard to tell that the queen of the Imperium did not seem willing to submit to her fate as a “surveillance tool”, and she had her own ambitions!
Also, if the emperor were only a puppet of the warlords, how could he have commanded the army to secure such a strategic triumph in the frontline against the Covenant Alliance?
Even if it was part of the Covenant Alliance’s scheme of “retreating for a better attacking position”, as Li Yao and the deputy commander of the Black Wind Fleet had speculated before, the emperor’s leadership over the army of the Imperium was certainly unquestionable. In the enormous counterattack of the Imperium that lasted years, what kind of role had Queen Li Linghai been playing, and what was she up to exactly?

China Has A Theory About Its New COVID-19 Cases
China now reports few to none domestically transmitted COVID-19 cases — only 12 cases were reported on Dec. 15.To get more news about shanghai coronavirus cases, you can visit shine news official website.
But a flurry of recent cases has Chinese public health officials worried. They claim that the cases stemmed from workers who had contact with imported food and packages.Beijing has now banned nearly 100 suppliers from 20 countries and at one point recommended travel restrictions in at least two cities where frozen food handlers contracted the coronavirus.
There's a problem with this theory. The cases directly contradict international health guidance, which says such transmission is highly unlikely. Emanuel Goldman, a microbiologist at Rutgers University's New Jersey Medical School, wrote in the Lancet this summer that "the chance of transmission through inanimate surfaces is very small," adding that objects not "in contact with an infected carrier for many hours do not pose a measurable risk of transmission in non-hospital settings." Since then, Goldman told NPR that more research has come out to corroborate his claim.
What is going on? Here's what we know about the subject of transmission via fomites — objects contaminated with viral particles.Why so unlikely? First, you'd have to touch a freshly contaminated surface, Goldman explains. Like a doorknob. Or food packaging.
Then, "you have to touch your face" without having washed your hands. And specifically, the mouth, nostrils or eyes — the entry points for the virus.
The World Health Organization uses the phrase "highly unlikely" to describe the chances of contamination from food packaging — but with an abundance of caution urges that the food industry "reinforce personal hygiene measures" for employees.
The Chinese Center for Disease Control and Prevention has said there is a "very low risk" of infection from frozen foods.
But it doesn't agree 100%. China's CDC claims that it has identified one case in which live viruses were carried into China via the cold surfaces of imported items and later infected workers. The organization warned workers handling foods stored in refrigerated conditions that they are at "a relatively high risk" of getting the coronavirus and should increase their efforts to protect themselves.China has reported at least four clusters of cases since this summer that it attributes to virus-contaminated objects that have traveled from virus-stricken countries and regions.
In November, Shanghai health authorities stated that seven cases were linked to the city's Pudong International Airport. They claim that the source is a shipping container from North America, which two of the seven patients entered to clean without masks. The other five infected individuals include those who also worked in the airport freight section as well as their spouses.
The port city of Tianjin also identified two new COVID-19 patients earlier that same month. A Tianjin CDC official, Zhang Ying, said both individuals, a warehouse loader and a truck driver, had been in physical contact with a shipment of hog heads from North America. According to CCTV footage, officials said the truck driver, not wearing any personal protective equipment, picked up a hog head when it fell out of the warehouse.
The frozen meat and its package have yet to be tested to this day, but Zhang said samples taken from the spot where the pig head fell on the ground came back positive for the coronavirus. There was also a genetic match to the samples taken from the two patients.

The Chinese Center for Disease Control and Prevention has said there is a "very low risk" of infection from frozen foods.
But it doesn't agree 100%. China's CDC claims that it has identified one case in which live viruses were carried into China via the cold surfaces of imported items and later infected workers. The organization warned workers handling foods stored in refrigerated conditions that they are at "a relatively high risk" of getting the coronavirus and should increase their efforts to protect themselves.China has reported at least four clusters of cases since this summer that it attributes to virus-contaminated objects that have traveled from virus-stricken countries and regions.
In November, Shanghai health authorities stated that seven cases were linked to the city's Pudong International Airport. They claim that the source is a shipping container from North America, which two of the seven patients entered to clean without masks. The other five infected individuals include those who also worked in the airport freight section as well as their spouses.
The port city of Tianjin also identified two new COVID-19 patients earlier that same month. A Tianjin CDC official, Zhang Ying, said both individuals, a warehouse loader and a truck driver, had been in physical contact with a shipment of hog heads from North America. According to CCTV footage, officials said the truck driver, not wearing any personal protective equipment, picked up a hog head when it fell out of the warehouse.
The frozen meat and its package have yet to be tested to this day, but Zhang said samples taken from the spot where the pig head fell on the ground came back positive for the coronavirus. There was also a genetic match to the samples taken from the two patients.
At Sihl City, the landmark shopping center planned by architect Theo
Hotz of Zürich, Jakob AG was able to implement several installations
that play a key role in the design of the facility. They clearly
illustrate that the company’s products not only inspire aesthetic
innovations but also offer cost-effectiveness benefits.To get more news

Inaugurated in the spring of 2007 and stretching over an effective area of approx. 100,000 m2, Sihl City in Zürich Wiedikon is one of Switzerland’s largest and most advanced shopping and leisure complexes. Planned by architect Theo Hotz and built at a cost of approx. CHF 620 million, the large facility on the premises of a paper mill on the Sihl river attracts 20,000 visitors a day, offering a broad range of shops, restaurants, entertainment venues, and cultural events. Jakob AG participated in several facets of this project which also represents a landmark from an architectural point of view. The eastern façade of the parking garage with a capacity of 850 cars was equipped with a “green wall” planned by Jakob AG, and the southern façade of the same building was covered with a stainless steel net across a large surface. In addition, Webnet structures were prominently used in the hallways of the shopping center.
With a height of 23 meters and a width of 25.5 meters, the green wall of the parking facility at Sihl City represents a category of façade greening projects whose sheer size and resulting loads make it impossible to apply standard solutions. Jakob AG designed the training systems in cooperation with the planners of Raderschall, a Meilen-based landscape architecture firm, and implemented this façade greening task as a subcontractor. The scope of delivery included the planning and supply of the training systems but also their installation on site by experienced Jakob technicians. The relatively wide-meshed training structure, formed by vertical and horizontal ropes of various thicknesses, is suspended at a distance of 70 cm in front of the eight-stories high, sectional-glass lined eastern façade of the parking facility in order to provide sufficient growing space for the plants which comprise in this case mainly Chinese wisteria and birthworts. Especially designed, rugged steel spacers permanently connected to the supporting structure of the building ensure safe anchorage of the ropes. The distribution of the spacers, mounted to the slabs of the second, fourth, sixth, and eighth floors, follows a clear-cut grid pattern that matches the facility’s façade design which is characterized by a vertical strip pattern. The same applies to the vertical ropes of the training structure which optimally matches the graphically strong aspect of the façade.
While the green wall on the eastern façade of the parking garage is particularly remarkable for its sheer size, the curtain over the building’s southern façade with Webnet represents a hitherto unique application of this product. It is impressive with regard to both design and cost-effectiveness. For this façade, architect Theo Hotz wanted a “skin-like”, large-area structure that would preserve the original character and aspect of this sober and practical building to the greatest possible extent. A fine-meshed stainless steel net turned out to be the optimal solution of this task. Viewed from a distance, the Webnet appears here like a film tightly stretched over the edges of the fairfaced concrete building. Only a close view reveals the fine-meshed structure of the stainless steel net which is very unobtrusively attached to the front surfaces of cantilevered floor slabs. A unique visual effect is also created by the Webnet on the internal façade of the parking garage. Here, the visitor is offered a largely unimpeded view which prevents the claustrophobic feeling that many people experience inside parking facilities. And to comfort more anxious souls, the external perimeters of the floors are additionally secured by a solid railing arranged in front of the Webnet curtain. Thanks to Webnet, Theo Hotz was able to design a façade that is not just architecturally unique. The solution, implemented at relatively low cost, is also convincing from the cost-effectiveness point of view – not least because of the low maintenance costs of the stainless steel net.
Almost as remarkable as the Webnet façade of the parking facility is the design of the stairways inside Sihl City, where stainless steel nets replace the conventional banisters. This applies especially to the spiral staircases whose cores are secured with net stockings. The stockings are attached to the concrete ceiling of the staircase with a metal hoop and held in shape by vertically arranged stainless steel ropes running along the internal surface and fixed to the lateral surfaces of the slabs and steps. The seamless nets, finished at the factory, were installed on site in record time by Jakob AG technicans. Cost considerations also influenced the choice of Webnet at Sihl City, but in addition to the price advantage, the architect was fascinated by the possibility of securing a flight of stairs with a minimum amount of material without compromising the lucid and pure appearance of the architectural assets. Quite to the contrary: the tightly stretched stainless steel stocking visually emphasizes the cylindrical form of the central core, an effect that could not be achieved with a conventional banister.

MAD Architects, led by Ma Yansong, has created a "living green wall" for
its Beverly Hills' residences in Los Angeles, which is the first
completed project of MAD in the USA.To get more news about stainless steel green facade, you can visit boegger.net official website.
Named Gardenhouse, the project, located at 8600 Wilshire Boulevard in California’s Beverly Hills, is a mixed-use scheme consisting of 18 residential units above ground floor commercial space. MAD first released design for Gardenhouse in 2015 and then resealed construction images in 2018. MAD's design evokes the lush landscape of Beverly Hills, MAD wanted to create a “hillside village” with residential units “growing” from the building’s living green wall.
The design supports the studio's architectural approach like in other projects increasing the inhabitants' emotions like living in the nature.Peaking above the landscaped envelope, a cluster of white façaded, irregular-shaped windows, and gabled-roof structures create a dynamic neighborhood, and a playful, witty, though simple homage to the iconic hillsides of Los Angeles.
The design is described as "one of the largest living green walls in the USA" upon completion. "This defining envelope is covered in lush plantings of native, drought-tolerant succulents and vines, whose familiarity to the local climate negates the need for extra irrigation and maintenance," said MAD in its project description.
"The result is a unique texture forming an organic, natural, seasonal addition to the neighborhood streetscape."Covering a total of 4,460-square-metre area, "hillside village" offers a variety of different housing typologies: two studios, eight condominiums, three townhouses and five villas.
As the studio highlights, "this healthy mixture results in a high sense of
