As Galaxy Technology's stall grows, Wang Donglai has more and more things to deal with.
Although a project leader will be established, many decisions can only be made by Wang Dong.
For example, it is the processing of packaging technology, such as the development of artificial intelligence medical auxiliary diagnosis system and other issues.
Compared to the founders of other companies, Wang Donglai is the absolute soul of Galaxy Technology.
At present, many technologies of Galaxy Technology were developed by Wang Donglai, or played a major role.
It can be said that without Wang Donglai, there would be no Galaxy Technology today.
Not only Wang Donglai knows this, but other employees of Galaxy Technology also know this.
In terms of semiconductors, although Zhang Rujing rejected Wang Donglai's solicitation, he still showed his goodwill and was willing to help in some matters.
Wang Donglai had actually expected this. It can only be said that he was neither very happy nor very disappointed.
If the packaging technology test is passed, then the next thing will be very simple.
Utilize domestic semiconductor technology and then use packaging technology to produce qualified chips.
Whether it is drones, artificial intelligence medical auxiliary diagnosis systems, etc., a large number of chips are required.
These chips do not necessarily require the most advanced chips.
Through more advanced algorithm programs and packaging design solutions, the performance of the chip is improved.
The only disadvantage of doing this is that the cost will be higher.
And this point is not a problem at all for Wang Donglai.
Because whether it is drones or other products, they are all products with high net profit margins. Just increasing the cost of the chip will not have much impact at all.
After handling this matter, Wang Donglai continued to study artificial intelligence software.
At this moment, an email from an overseas bald eagle made Wang Donglai stop.
“Professor Wang, congratulations, no one in our country has ever won the Adams Prize in Chemistry!”
Yao Qizhi congratulated Wang Donglai with excitement.
Wang Donglai’s expression was very calm and calm, and he was not proud of winning the award.
“Not winning an award does not mean that we are inferior to white people, it just means that our academic voice is not high.”
“This award is actually average!”
Wang Donglai's tone was calm and he didn't mean to take this award seriously at all.
The smile on Yao Qizhi's face faltered. He didn't expect Wang Donglai to react like this.
This is also because the two of them don’t spend much time together and don’t know each other well enough.
If it were everyone at Tangdu Jiaotong University, they would not say this when they learned about this award.
After a brief silence, Yao Qizhi said with some emotion: "You guys born in the 1990s are indeed young people. The generation gap between me, an old guy, and you is too big."
"The Adams Chemistry Award is an important award in the field of chemistry. Do you not know the information about this award?"
Hearing what Yao Qizhi said half-jokingly, Wang Donglai immediately said: "How could I not know this? The Adams Chemistry Award is an award of the Bald Eagle Chemical Association, sponsored by Bald Eagle Organic Synthesis Co., Ltd., Bald Eagle Organic Reaction Co., Ltd. The company was jointly established in 1959 and is co-sponsored by the two institutions and the Bald Eagle Chemical Society's Division of Organic Chemistry, named after Bald Eagle organic chemist Roger Adams. "This award is awarded every two years since 1995 to scientists who have made outstanding contributions in the field of organic chemistry."
"So far, nearly half of the 24 winners have won the Nobel Prize in Chemistry."
Wang Donglai said this information in one breath without even pausing. .
Hearing Wang Donglai’s story, Yao Qizhi was also a little surprised.
"Since you know that nearly half of the winners of this award will win the Nobel Prize in Chemistry, aren't you excited?"
"You know, this is the Nobel Prize!"
Yao Qizhi looked at Wang Donglai curiously and asked aloud.
Shaking his head, Wang Donglai acted very calmly and said: "To be honest, I am a little excited, but I hope that such an authoritative award can appear in China."
Yao Qizhi showed a wry smile on his face and said: "Then this will be difficult!"
"Nothing is difficult in the world, as long as there are people who are willing. In fact, as long as domestic scientific researchers can change their mentality, it may not be difficult to achieve this. You must know that our number of highly qualified people is one of the best in the world. If domestic scholars work together If so, no If you mention anything else, the value of these awards in the West will plummet, and it will be a farce in the end.”
“It’s just that it’s too difficult to do this!”
Wang Donglai said with some emotion.
Yao Qizhi also nodded silently and said, "I understand your patriotism, but academic matters cannot be solved by patriotism alone."
< br>"Development is the last word. As long as our country's technology becomes stronger and more talented, the academic voice will naturally transfer to us. At that time, it will be us who will formulate industry standards."
"Then are you going to Bald Eagle to attend the award ceremony?"
Finally, Yao Qizhi asked.
Wang Donglai also thought for a moment, then nodded and said: "Go."
The reason why he chose to go to Bald Eagle to receive the award was because Wang Donglai wanted to recommend him well. Phosphorus batteries, and more products from Galaxy Technology.
As for his own safety, Wang Donglai is not worried.
"Well, if you go and receive this award, you will break the domestic record again. It will bring glory to the country and it will be good for you."
Yao Qizhi nodded and said.
……
May 27th.
It is time to set a time to go to Bald Eagle. This time Wang Donglai is not going alone, there is also a professor from Tianjin University.
This professor from Tianjin University is named Ruan Wei. The reason why he went to the capital with Wang Donglai was because he took the initiative to contact him. Because Professor Ruan specialized in filter chips, Wang Donglai agreed that the two of them would go to Bald Eagle together.
Actually, Wang Donglai knew that Professor Ruan was probably here for him.
Either he is looking for his own money, or he wants to use his mathematical knowledge to help him with project research.
Airport.
At the agreed location, Wang Donglai met Professor Ruan.
“Professor Wang is so young!”
As soon as Professor Ruan saw Wang Donglai, he took the initiative to say hello enthusiastically.
"Professor Ruan is so polite. You look very young and feel like you are only in your thirties."
The sedan chair was carrying people, Professor Ruan took the initiative to express his kindness, and Wang Donglai naturally would not refuse. People are thousands of miles away.
After exchanging pleasantries, they all sat down.
Unlike Wang Donglai, Professor Ruan did not go to Bald Eagle alone, and was accompanied by his lover Fan Lili.
After a brief introduction, Professor Ruan took the initiative to chat with Wang Donglai and said: "Professor Wang, I heard that you are going to the Bald Eagle to receive the Adams Award for Chemistry, which is amazing!"
" Professor Ruan is so polite, I am also a little surprised by this award!" Wang Donglai responded calmly! After answering, he asked aloud: "What happened to Professor Ruan going to Bald Eagle?"
Ruan Wei showed a smile on his face and said: "There is an international microwave academic exchange here in Bald Eagle. He invited me to attend, and my wife and I happened to come over to take a look.”
"Oh, by the way, I study filters. I founded Novus Systems Co., Ltd. with my friends. The main product is FBAR filters."
"Professor Wang, you are a genius in the field of mathematics. , I heard that you are also very interested in semiconductors. If you don’t mind, we can talk more.”
“To tell you the truth, we are working on it. When doing research, I often encounter algorithmic problems. It would be great if a mathematical genius like Professor Wang can give me some advice. I wonder if Professor Wang can give me some advice occasionally when he is free? "
Ruan Wei's posture was very low, and he did not show off in front of Wang Donglai because of his own achievements and age.
This time he took the initiative to find Wang Donglai and went to Bald Eagle with Wang Donglai, just to build a good relationship on the road so that he could ask for help when he encountered mathematical algorithm problems later.
Sometimes, top mathematicians can play a great role and can be said to be an excellent assistant.
The filter chip looks small, but it is actually used in a wide range of applications. Filter chips are used in the mobile phones we use in our daily lives. In addition, there are also various electronic products that need to receive signals.
The principle is also very simple, which is to filter radio signals and reduce external interference to ensure communication quality.
It plays an extremely important role in communication.
"Professor Ruan is too polite. Let's communicate and learn from each other. To be honest, I am also quite interested in filter chips." Wang Donglai said this humbly instead of being arrogant.
Ruan Wei breathed a sigh of relief when he heard Wang Donglai's answer.
Seeing that Wang Donglai was so young, to be honest, he was a little worried that Wang Donglai would be difficult to talk to, so he refused his proposal and made it difficult for him to step down.
Fortunately, such a thing did not happen.
“I didn’t expect that Professor Wang is also interested in filter chips, so I will talk to Professor Wang about it.”
Ruan Wei started to talk to Wang Donglai with some excitement.
"First of all, we need to know what a filter chip is? In order for sound to be transmitted thousands of miles away, it must first be converted into high-frequency radio waves. The information is encoded into sinusoidal waves with billions of crests per second. The opponent's mobile phone can receive and restore them without any flaw. Chaos, this is the nature of radio frequency devices, and the core component of radio frequency devices is the power amplifier Chip, also called radio frequency chip. ”
“Another core component of radio frequency devices is filters. Filters can be mainly divided into surface acoustic wave (SAW) and bulk acoustic wave (FBAR/BAW) technologies. Filter, the filter can remove signals outside the target frequency band and is a very basic electrical circuit device. ”
“The high-end filter uses the principle of piezoelectric effect and introduces sound waves to work. Its substrate and coating use some new materials, and the processing precision is very high, involving thin film deposition and micro-electronics. Mechanical process. ”
“Bulk acoustic wave filter performance compared to surface acoustic wave It has obvious advantages in allowing mobile phones and other communication equipment to filter radio signals to improve call quality. It is mainly used in mobile electronic devices such as mobile phones, tablets and GPS. "
"At present, it is used in many high-end domestic devices. The filter chip I developed is used! ”
When he said this, Ruan Wei looked proud.
Wang Donglai also praised the venue and praised it a few times. Ruan Wei was not so easy to get carried away, but in the face of Wang Donglai's praise, he couldn't help but feel proud.
After all, Wang Donglai’s academic achievements are extremely extraordinary.
Not only in the field of mathematics, but also in computers and other fields, he has achieved amazing results.
So, being praised by Wang Donglai naturally made Ruan Wei feel proud.
"High-end filters have very high technical requirements in terms of center frequency, cutoff frequency, linearity, sensitivity, etc., so they have always been monopolized by foreign RF device giants such as Qorvo. However, this is history. Domestic filtering The equipment has been developed."
Wang Donglai looked thoughtful after hearing this. He said subconsciously: "Professor Ruan, this technology should also be used in military and national defense communication technology. Then this should be considered a sensitive technology involving secrets. Will it have any impact?"
Ruan Wei He waved his hands indifferently and said, "Professor Wang is right about this, but it has nothing to do with my company. I The products we produce are provided to enterprises.”
“Professor Wang, I’m afraid you don’t know how important a filter chip, which is less than one square millimeter, is to smartphones. , it can be said that without this chip, whether it is a smart phone or an old-fashioned mobile phone, it will become a brick and lose its communication function."
“Most of the country’s annual demand for more than 10 billion units must be imported from abroad. In particular, high-end filter chips are completely dependent on foreign imports. One chip costs dozens of yuan, but the cost is less than one yuan. Even high-end chips only cost five or six yuan. Just because we can’t produce them, we sell them at such a high price.”
Wang Donglai didn't expect that Ruan Wei would have such thoughts. He was stunned for a moment and then reacted.
Chinese people are not fools and are willing to be taken advantage of by foreigners.
Chips are sold abroad at high prices and harvested in China. No one is willing to accept it. It is just that the situation is weaker than others, so they can only endure it forcefully and dare not speak out.
But once a breakthrough is achieved, naturally one is not willing to bear it.
So, Ruan Wei’s emotions are completely understandable.
Nodding, Wang Donglai changed the topic and said: "Professor Ruan, you might as well talk about the filtering algorithm. I'll see if I can help you, so that you won't encounter problems later. I don't understand this algorithm yet."
< br> Ruan Wei showed a smile on his face and said: "There are not many filtering algorithms, including limited amplitude filtering, median filtering, and arithmetic. Average filtering method, recursive average filtering method, median average filtering method, limiting average filtering method, weighted recursive average filtering method, debounce filtering method, limiting debounce filtering method, first-order lag filtering method, etc... …”
From the departure hall to getting on the plane, Ruan Wei excitedly and enthusiastically introduced his major to Wang Donglai.
Wang Donglai is also very studious. Not only can he keep up, he can also discuss things with Ruan Wei from time to time, which makes Ruan Wei even more happy. (End of this chapter)
