Chapter 692 I know what to do
Wang Di lives not very far from here. She has to take a few bus stops to go back. Wang Yu gave her so much money. This is also the reason, because she sent Wang Yu here, but when she went back, no one was there. To deliver, you need to provide transportation, which is also an expense.
After Wang Di left, Wang Yu and Li Xiyan came to the presidential suite upstairs.
Due to the homework they had just done last night, neither of them had much to do now. They had to get up early tomorrow morning and drive a long distance back to the Magic City, so Wang Yu did not propose any special program tonight.
Li Xiyan had been waiting for Wang Yu to speak, but Wang Yu refused to say anything. Li Xiyan couldn't bear it any longer, so she asked, "Hey, don't you do that tonight?"
Wang Yu actually had that idea in his heart, but he was really not very interested in Li Xiyan's figure, and he was really tired in the past two days. He was worried that he would be distracted when driving back tomorrow, so he stopped thinking: "No, tomorrow Let’s sit down in Hui Modu, I want to think carefully about the acquisition of Xia Fei Group in Suzhou tomorrow!”
As soon as Li Xiyan heard this question, she immediately became interested. She believed Wang Yu's words for the time being and said, "Did President Gao send a message over there?"
Wang Yu said: "It's sent!"
After saying that, he took out his mobile phone and opened the WeChat interface with Gao Shoudong: "When we were buying shoes just now, he sent them. This company is pretty good, I think!"
Li Xiyan looked at the messages on Wang Yu's mobile phone. There were a lot of messages. She didn't read them in detail. She just read the introduction and the beginning of the message, and then said: "It's not bad!"
"This is an old military industrial enterprise in Suzhou. It used to be a state-owned enterprise, but later it was transformed into a private enterprise. It also introduced foreign capital and technology. I thought it would develop and grow, but later because of the conflict with France, the other party took it away. A lot of technology and capital, now Xia Fei Group has a nicer name, and the rest are all the existence of the Chinese military industry, if we go to acquire it, it will definitely be a word!" Wang Yu said.
Li Xiyan also thought of the original situation of her Xiyanwei, which was similar to that of Xia Fei Group. If it weren’t for Wang Yu’s financial intervention, Xiyanwei might have disappeared from the world now. Now Wang Yu wants to use the same Li Xiyan didn't know if she could succeed again in order to acquire Xia Fei Group, so she kindly reminded her, "You have never been in the military industry. Isn't this too risky?"
Wang Yu said: "No, when I acquired Xiyan Micro, did I do any chips? Didn't I do that too?"
Li Xiyan said: "At that time, you had chip technology, but you didn't have the military industry? You wouldn't tell me that you also had the technology to make aero engines, right?"
Wang Yu shook his head and explained: "Although it doesn't exist, did it exist shortly after I acquired Xiafei Group? This thing mainly relies on chips. Military electronics and mobile electronics are actually different types, and they are also things that change the soup without changing the medicine. , I know how to do it!”
The requirements for military-grade chips are -55°C~+150°C. They are mainly used in military fields such as missiles, tanks, and aircraft carriers. Electronic components in the military industry are the most stable, reliable, and anti-interference in any part. , high precision.
The requirements for aerospace-grade chips are -55°C~+150°C. Aerospace-grade components are the highest level of components. They are mainly used in aerospace fields such as rockets, spacecrafts, and satellites. The operating temperature is the same as that of military-grade, but on the basis of military-grade Add anti-radiation and anti-interference functions.
In fact, the protection of the chip by packaging is limited. High-energy particle flow can penetrate the packaging material of the chip and enter the inside of the chip to cause damage to the chip.
Radiation-resistant reinforcement mainly includes two reinforcement technologies: design and process, or a combination of these two technologies is used as needed. Broadly speaking, radiation-resistant reinforcement design includes material design, system design, structural design, circuit design, device design, packaging design, software design, etc. In a narrow sense, it generally refers to the method of mitigating the damage of ionizing radiation through circuit design and layout design.
Process reinforcement is a technology that uses special processes to perform radiation resistance reinforcement. Process steps can be proprietary to the manufacturer or military, or they can be added to a standard manufacturer's wafer fabrication process for ruggedization purposes. Radiation-resistant reinforcement process technology is highly specialized and complex.
Radiation-resistant reinforcement design can be carried out in the following ways from the aspects of system, structure, circuit, and device-level design technology:
One is to use a multi-level redundancy approach to mitigate radiation damage. These levels are divided into component level, board level, system level and aircraft level;
The second is a logic circuit design method that uses redundant or doubled structural components (such as three-module redundancy), that is, the voting circuit determines the output logic based on at least two votes;
The third is to use circuit design and layout design to mitigate the damage of ionizing radiation. That is, the use of isolation, compensation or correction, decoupling and other circuit technologies, as well as doped well and isolation trench chip layout design;
The fourth is to add error detection and correction circuits, or self-repair and self-reconstruction functions;
The fifth is to use circuit design and layout design to mitigate the damage of ionizing radiation. That is to say, circuit technologies such as isolation, compensation or correction, and decoupling are used, as well as chip layout design of doped wells and isolation trenches.
In addition, the use of ruggedized analog/mixed-signal IP technology and SIGE ruggedized design technology is also an effective way to improve the chip's radiation resistance.
Special processes for radiation-hardened chip reinforcement are increasingly used in conjunction with ruggedized designs. Because radiation-resistant reinforcement process technology has very high professional attributes and high complexity, only a few manufacturers can master this technology.
Chips of different grades and specifications have different requirements from design to packaging and testing, and their usage scenarios are also quite different. Generally speaking, the higher the specifications of the chip, the more redundant the chip design, the more rigorous the packaging, the more complex and strict the testing process, and the higher the difficulty and cost of research and development.
But these problems are not worth mentioning in the face of the powerful value system. Wang Yu only needs to press a few buttons to solve them.
"What about the medical equipment? Have you told the Han family? Aren't you in the capital now? Why don't you go talk to them tomorrow?"
Wang Yu said: "It's simple. I can just go to Miss Han's company in Shanghai. He also has equipment there!"
It's not like Wang Yu has never thought about going to Han's house before, but if he goes, he must disturb the other party. It's not good. If you agree not to disturb the other party, then don't disturb the other party.
While Wang Yu was talking, his hand came out of control and hit Li Xiyan on the thigh.
Li Xiyan watched Wang Yu's hand keep moving up, and it was about to reach the thigh. She didn't dodge, but looked at Wang Yu's face, meaning to ask him where to touch it.
