Chapter 202
Wu Hao's words caused an uproar in the conference room.
Not only the people from Ziwei Optoelectronics were questioning, but even several team leaders from the Military Research Institute jumped up.
They had learned about Ziwei Optoelectronics' detector.
We also know the detector levels of the Institute of Semiconductors and Qinghua Purple Light.
That is already the top level in the country.
Although it is not at the top level in the world, it is still among the advanced ranks.
None of this works.
Want to increase it three times?
Let alone China, not even the United States and Europe.
Jiang Hongfeng couldn't help teasing:"Director Wu, do you really understand photoelectric detectors? Didn't you graduate in the field of high-power lasers? If the indicator is increased three times? Then there is no need to carry out the project of the Military Research Institute"
"That's right, if you improve it three times, no one in the world can do it."
"Not to mention increasing it by three times, it is difficult to increase the growth time of a single chip alone."
"Yeah, I don’t think it’s possible"
"He was just looking for an excuse to kick Ziwei Optoelectronics, right?"
……
People below were talking a lot.
Liu Xiyao also turned a little pale.
She also couldn't figure out whether Hao really didn't want to give face or if he had other hidden agendas.
Judging from the indicators proposed by Wu Hao, it really seems unreasonable, because it is simply impossible to achieve.
But judging from his usual behavior, he doesn't feel like someone who is unreasonably making trouble because of his past experiences and wants to avenge his private revenge.
Is there... another miracle?
The conference room was noisy.
Wu Hao remained silent.
Yu Tao didn't speak either.
After staring at Wu Hao for a long time, he suddenly reached out and knocked on the table:"Quiet, what are you yelling about? Let Director Wu finish what he said."
"I didn't accept anything he said."
Jiang Hongfeng couldn't help but said
"Whether you accept it or not is your business. As I said, Director Wu is solely responsible for the control of this project in the institute. It's up to him to decide whether you accept it or not."
Yu Tao glanced at him impatiently and motioned for him to sit down.
Then he looked at Wu Hao:"Director Wu, can you briefly explain what you just said?"
"No need to explain, it’s just what it means literally.
Wu Hao pointed to the parameters on the projection screen and said,"All parameters have been increased three times." Without achieving this level, guidance devices cannot stand out."
"But this parameter……"
"can do"
"How to do it? Is it difficult to meet your standards for dynamic response? Wu
Hao looked back at him:"Improve the dynamic response index and change the core chip to an avalanche photodiode.""
"However, the output current of avalanche photodiodes is large, so bias voltage control is required. The ones with low external bias voltage are photodiodes. Liu
Xiyao also asked doubtfully.
"Redesign the bias voltage circuit, like this."
Wu Hao casually started writing and drawing on the small blackboard.
Only halfway through the drawing, the conference room became quiet.
Everyone was dumbfounded.
This specially appointed expert actually knows electricity?
Although they say that light and electricity are inseparable, Good optical engineers all know electrical knowledge.
But it is unique for someone like Wu Hao to start rewriting the diode bias voltage design circuit directly in the conference room, right?
After ten minutes, a complex circuit system was completed.
Wu Hao Circle the dots on it with a pen and say at the same time:"The bias circuit is the bottleneck, but this circuit system can reduce the bias voltage and also use avalanche photodiodes."
"Manager Liu, take a look."
Jiang Hongfeng was a little surprised.
His professional knowledge was limited, so he quickly looked at Liu Xiyao
"This... design has changed a lot. Might have to go back and test it out. However, it seems that no one has ever made such a change. Very...novel. Liu
Xiyao looked fascinated and murmured back.
"Also, regarding long-term stability issues, avalanche photodiodes are not as good as ordinary diodes. Therefore, the detector packaging needs to be redesigned."
Wu Hao continued
"Is the packaging also changed? Doesn’t that mean the cycle is longer? Yu Tao said doubtfully
"No, it's just one more process. The material of the detector package is modified to a temperature-insensitive carbon-sulfur alloy. And change the photosensitive material to perovskite material."
When they heard the name, everyone was surprised.
Wu Hao knew about perovskite and said that he was a truly knowledgeable person.
Because the world is currently developing perovskite photodetectors using perovskite as the material, which is definitely the forefront. The most high-end level of Yuan.
Jiang Hongfeng was speechless.
He sat down on the chair, like a defeated rooster.
But Yu Tao became excited, sat up straight, stared at the technical indicators displayed by Wu Hao and murmured:" If we can really reach this level, our guidance accuracy will surpass that of any other country in the world."
"That's right, that's what it's about. Otherwise, what is the point of asking me to be a specially appointed expert?"
Wu Hao took back his mobile phone.
With black technology in hand, how can he still get a mere detector?
Everyone in the conference room has been discussing in low voices and buzzing non-stop.
Yu Tao was excited for a while, then looked at the others and said loudly :"Everyone, be quiet."
The conference room became quiet.
Yu Tao looked at Jiang Hongfeng and said,"Mr. Jiang, you understand what Director Wu means, right? Your product indicators still need to be improved. So let’s forget about this cooperation."
"……"
Jiang Hongfeng was speechless.
Come with full confidence, but return with failure.
If it is for other reasons, it can even operate at night.
Eat a meal, drink wine, soak in a hot spring and sing K.
There are many methods.
But facing Wu Hao, he couldn't think of anything.
I fined him 7 million yuan and made him bankrupt. How can I still give myself a good face now?
Thinking about it, I blame myself.
At the beginning, it was because Wu Hao and the others were small businesses, and they temporarily lowered their prices during the bidding process, which messed up the relationship they had established privately with another company.
That time, he was originally able to get nearly eight points of rebate.
In the end, I didn't even get anything.
Therefore, when there was a problem with Wu Hao's delivery date, Jiang Hongfeng didn't give him any face. He fell out without saying a word and directly fined him.
There will be judicial proceedings without a fine.
Now comes retribution.
A big deal fell through just in front of my eyes.
"Okay, that’s it for today’s meeting, let’s break up."
Yu Tao waved his hand.
Then he stood up and walked to Jiang Hongfeng and said,"Mr. Jiang, I won't give it away."
"OK, OK."
Jiang Hongfeng nodded, packed her things and walked out with the four of them.
Before leaving, Liu Xiyao looked back at Wu Hao.
Wu Hao happened to also look up at her.
Liu Xiyao stopped for a moment and looked at Wu Hao blinked.
Wu Hao shook his head slightly.
Then, Liu Xiyao withdrew her gaze, turned around and followed out.
After everyone left, Yu Tao returned to Wu Hao:"Director Wu, the detector you mentioned Can the solution be released?"
"Can"
"Can we appoint a company to use your solution to improve the design of the detector?
Wu Hao turned his head and glanced at him:"Does Director Yu have a goal?""
"Yes, an emerging company in Yanjing, Beidou Optoelectronics Technology Co., Ltd."
"New business? Do you have the strength?"
"good. In fact, it is a company started by a teacher from the Institute of Semiconductors. It has a large factory in northern Hebei.
Wu Hao nodded:"Is it related to the institute?""
"Yes, both have advantages in terms of price."
"Okay, if you think it makes sense, find a time to make an appointment with the three parties. After passing my level, I can sell them the detector solution."
"Okay, okay, Director Wu. so perfect"
"Okay, I'm leaving first. When you get back in touch, give me a call."
After saying that, Wu Hao stood up and left the conference room, walking away leisurely.
