Isola Develops Halogen-Free Material for PCBs

Isola Group S.a.r.l. has developed a halogen-free, ultra-low-loss laminate and prepreg material for RF, microwave, and high-speed applications. The TerraGreen halogen-free materials for multilayer printed circuit boards (PCBs) target high-performance designs including power amplifier boards for 4G LTE base stations, Internet infrastructure, and cloud computing. Isola Group, a material sciences company, manufactures copper-clad laminates and dielectric prepreg materials used to fabricate advanced multilayer PCBs.To get more news about Halogen Free PCB, you can visit pcbmake official website.

"Electronics manufacturers have long-expressed the need for halogen-free, ultra-low loss, lead-free assembly material for high-speed digital and RF/microwave markets," said Tarun Amla, executive vice president and chief technology officer, Isola, in a statement. "Isola's investments in R&D have successfully resolved this issue with our proprietary TerraGreen resin system."

The TerraGreen portfolio consists of a full offering of cores and prepreg that use spread-glass fabric. The dielectric constant (ranging from 3.00 to 3.45) and dissipation factor (ranging from 0.0030 to 0.0035) remain stable over a wide range of frequencies and temperatures, according to Isola. Core thicknesses are available from 0.002" to 0.018", 0.020", 0.030" and 0.060".

The lead-free assembly material is said to be easy to process. The high-performance and halogen-free material uses a short-lamination cycle; is easy to drill, and does not require plasma desmear. The prepreg shelf life is similar to FR-4 materials.

TerraGreen is suitable for high-layer count, high-speed digital, backplanes, and is compatible with Isola's FR-4 materials for hybrid designs.

RF circuit PCB design processing skills(on)

Because the radio frequency (RF) circuit is a distributed parameter circuit, it is easy to produce skin effects and coupling effects in the actual work of the circuit. Therefore, in actual PCB design, it will be difficult to control the interference radiation in the circuit, such as digital circuits and analog Interference between circuits, noise interference from power supply, interference caused by irrational ground, etc. Because of this, in the PCB design process, how to weigh the advantages and disadvantages to find a suitable compromise point, minimize these interferences, and even avoid the interference of some circuits, is the key to the success of RF circuit PCB design. From the perspective of PCB layout, this article provides some processing techniques, which is of great use to improve the anti-interference ability of RF circuits.To get more news about Cavity PCB, you can visit pcbmake official website.
1.RF layout
What is discussed here is the component location layout of the multilayer board. The key to the component location layout is to fix the components located on the RF path. By adjusting its direction to minimize the length of the RF path and keep the input away from the output, separate the high-power circuits and low-power circuits as far as possible. Keep the signal away from high-speed digital and RF signals.
The following techniques are often used in layouts.
1.1 Glyph layout
The components of the RF main signal are arranged in a zigzag pattern as much as possible. However, due to the space constraints of the PCB board and the cavity, many times cannot be arranged in a zigzag shape. At this time, an L-shape can be used. It is better not to use a U-shape layout. Sometimes it can not be avoided. The distance between them should be at least 1.5cm. In addition, when using an L-shaped or U-shaped layout, the turning point is best not to turn just after entering the interface, but to turn after a short straight line.
1.2 Identical or symmetrical layout
The same modules are made as much as possible or symmetrical.
1.3 Cross layout
The feeding inductance of the bias circuit is placed vertically with the RF channel, mainly to avoid mutual inductance between inductive devices.
1.4 45 degree layout
In order to use space reasonably, the device can be laid out in a 45-degree direction to keep the RF line as short as possible.
2. Cavity treatment
For the entire RF circuit, the RF units of different modules should be separated by a cavity, especially between sensitive circuits and strong radiation sources. In high-power multi-stage amplifiers, isolation between stages should also be guaranteed. After the tributary of the entire multilayer PCB circuit is placed, it is the treatment of the shielding cavity. The handling of the shielding cavity has the following precautions:
The whole shielding cavity is made into a regular shape as far as possible to facilitate the casting. For each shield cavity, try to make it rectangular, avoid square shield cavity.
The corner of the shield cavity is arc-shaped, and the shield metal cavity is generally cast-molded. The arc-shaped corner is convenient for drafting during casting.
The periphery of the shielding cavity is sealed. The lead-in of the interface is generally a strip line or a microstrip line. The different modules inside the cavity are microstrip lines. For 3mm, the microstrip line goes in the middle.
3mm metallization holes are placed at the corners of the cavity to fix the shielding shell. The same metallization holes should be evenly placed on each long cavity to strengthen the supporting effect.

Father-daughter stare down egg-cracking record

The staccato, rapid-fire cracking of eggs is a ubiquitous sound in the kitchen of the Oak Table Café.To get more news about Egg cleaning machine, you can visit dinneregg official website.
On an average day, owner Ross McCurdy says the Silverdale restaurant can go through 2,000 eggs. And with hungry customers waiting, time is imperative.All that repetition led to McCurdy being crowned the fastest one-handed egg-cracker in the world by Guinness World Records in 2009. And now his skills that will be tested when he takes to the set of celebrity chef Gordon Ramsay’s show “The F Word,” in June.
Ramsay, the British chef known for his profanity-laced tirades, will host McCurdy and his daughter, Mira, for a special live Father’s Day episode. The pair will compete against Ramsay and his daughter, Tillie, for a new world record: The most eggs cracked one-handed in one minute by a team of two.The F Word” features celebrities and families in cook-offs with Ramsay. A producer for the showrunner reached out to McCurdy after finding his current world record and seeing his family online, he said.
To be named champion, the teams must adhere to a specific set of rules. Eggs must be cracked into separate containers and the shells disposed of cleanly with one hand held behind the back. Officials from Guinness World Records will be on hand to enforce the parameters and declare a winner.“I’m nervous that I’m going to say something weird,” Mira McCurdy laughed. Still, she said, “It’s kind of cool,” to be meeting an A-list celebrity.
McCurdy’s eldest daughter grew up in the kitchen alongside her father, learning to crack eggs and make her own breakfast dishes. In preparation for the competition, the 12-year-old has been going to the restaurant and cracking hundreds of eggs after school with her dad.

China plots ‘rectification’ drive to bring Jack Ma’s Ant Group to heel

Beijing is accelerating plans to bring Jack Ma’s Ant Group more closely under its control as part of a “rectification” drive that would make it difficult for one of China’s richest men to fully rebuild his online empire.To get more latest ant group news, you can visit shine news official website.

Ant’s consumer lending unit and other fast-growing parts of the financial technology group will be carved out into a new financial holding company to be regulated by the People’s Bank of China, according to people briefed on discussions between the central bank and the company.

The reorganisation would bring Ant directly under the thumb of the regulators Mr Ma has long brushed up against, with public critiques that irked authorities and officials at China’s state-owned banks. The PBoC issued a public rebuke of Ant at the weekend, calling on the company to be overhauled and accusing it of “turning a blind eye to compliance requirements”.

One former regulator said: “The best solution is to break up Ant into a finance unit for its online lending, brokerage and insurance businesses that will be under full regulatory oversight, and a less regulated technology and data unit.”

The plan under consideration for Ant involves shifting its financially-licensed businesses — which include its payments, lending, insurance and wealth management ventures — into a new holding company, the people familiar with the matter said. However, they cautioned that the discussions with regulators were continuing.

“Ant has repeatedly emphasised it’s a technology company and the market valued it as one, but if it’s remade into a financial holding company, it will become a financial institution at heart, and the market will need to revalue it,” said He Zhisong, a lawyer at Zhong Lun, a law firm. “To head off antitrust concerns, Ant may also need to spin off some of its business lines.”
