At noon, after a simple meal with a working meal, the meeting continued.

When the control system was discussed, Li Mingliu and others from Yuanxin's side also joined in. And then it was over, and what was supposed to be a discussion of statistical requirements was turned into a purely technical discussion.

During this period, Zheng Zhenchuan wanted to remind these people not to go off topic, but when he saw Su Yuanshan, he listened to it with relish, and even picked up his notebook and kept writing and drawing.

Just as the engineer on Chengguang's side was about to go to get the drawings for the second time, Su Yuanshan raised his wrist and looked at the time.

"Ahem...... Why don't you stop for a moment?" Su Yuanshan raised his notebook and said with a smile: "Teachers, brothers and sisters, I have roughly written down that in order to achieve the ideal alignment system scheme, in addition to micromotors, it seems that many models of optical diodes are needed, right? ”

"Of course, I don't know about lithography machines, but I know from my technical intuition that lithography machines will definitely be the key to restricting the chip manufacturing process in the future - we are EDA developers, and we know that the upper limit of the process that Yuanxin EDA can design is far beyond the current fab process. Based on this, we must use new technologies and new circuits, after all, circuit boards are also maturing through trial and error. ”

"Especially for precision instruments such as lithography machines, it takes a long time to verify the heat dissipation and anti-interference. Zheng Gong, do you say yes?" Su Yuanshan said and asked Zheng Zhenchuan with a smile.

Zheng Zhenchuan smiled meaningfully and nodded: "That's right." Lao Zhou, you and Master Li don't fight. ”

Lao Zhou is an old engineer about 40 years old, and has been responsible for the design of various circuits of the alignment system here. Frankly speaking, he was quite complaining about Zheng Zhenchuan for asking a private company like Yuanxin to come over to help...... And he almost completely denied his previous work, which was really hard for him to accept. So in the past two months, he and Li Mingliu's team have been running in, striving to innovate and iterate on the basis of the original circuit design.

It's just that he didn't expect that Li Mingliu would bring up the old words again after the little boss came today, how could he bear it?

Lao Zhou snorted lightly: "Director Zheng, it's not a matter of whether to fight or not. The thickness of the circuit board will affect the overall accuracy of the lithography machine, so how can it be possible to rebuild all of them? It is better to start the design of the entire machine from scratch. ”

"That's fine. Li Mingliu confronted each other: "Zhu Jianting's mechanical CAD has been working on it for half a year, and the beta version can be taken out in the second half of the year at the latest, and then it can be redrawn - Chen Gong, your design team doesn't have to take a magnifying glass to look at the drawings every day." ”

The middle-aged man named Chen Gong coughed.

Su Yuanshan couldn't cry or laugh, and he also covered his mouth and coughed.

He knew that Li Mingliu was the kind of existence that had nothing to do even in T University. After entering the remote core, he was finally surrendered by himself and Xi Xiaoding, but it doesn't mean that he is really not arrogant - others are instantly stunned when they hear that the Institute of Optics of the Chinese Academy of Sciences is estimated, but it depends on what field.

Not to mention the mechanical and optical parts, that's someone else's field, and this person is awesome. But the IC and circuit part is Li Mingliu's field, and Li Mingliu also participated in the development of EDA simulation tools throughout the process, and he is a well-deserved expert in this area.

Seeing Su Yuanshan's reminder, Li Mingliu also knew that he had spoken sharply, and immediately said earnestly: "Old Zhou, really, listen to me." You're worried about the size, we can leave a blank space, but the previous thing really didn't work - I designed the VCD board of the far core myself, and it was drastically reduced from the size of a dinner plate to the size of a dictionary, and you said I was awesome! That's a lie!"

His last sentence made Lao Zhou's face look a little better.

"Our design is all based on EDA simulation, you say, how do you design the board to simulate, can you catch up with the simulation tools of the telechip?"

Lao Zhou opened his mouth, and when he found that he really couldn't refute, he began to sulk.

Su Yuanshan looked at Zheng Zhenchuan, and saw that Zheng Zhenchuan smiled like no one else: "It's okay, it's all for work, just get used to arguing." Don't look at Chen Gong drinking tea over there, when he first designed the drawings, he was louder than anyone else. ”

Zheng Zhenchuan said with a straight face: "Okay, today, while Mr. Xiao Su is also here, we will make up our minds completely." All circuits redesigned. ”

The person in charge of the statistical requirements on the side immediately asked, "Will there be any changes to the components, do you need to purchase new ones?"

"Let's design it first, and today you sort out what we urgently need at this stage. ”

Zheng Zhenchuan waved his hand, which can be regarded as a summary of today's meeting.

Su Yuanshan refused Zheng Zhenchuan's retention and farewell, and only let Li Mingliu and a few people send him to the parking lot. Here, Shen Haoran has decided to join Yuanxin, so several of them are all his own people.

"Mr. Shan, have you seen it?" Li Mingliu smiled bitterly: "When I was a child, I thought that the Academy of Sciences was mysterious and great, but I found out after getting close...... Alas!"

Shen Haoran smiled and stepped down the steps for the lithography machine department and said: "The tube technology that the military industry has been walking in before is mature and reliable after all. Although we are now making great strides to the semiconductor industry, the lithography machine is now mainly in demand for civilian equipment, so the investment is relatively small, and we are used to buckle the cord. ”

You can't say that you have built a powerful abacus that can be calculated 100 times per second under difficult conditions, and you don't need to use a calculator that can calculate 10,000 times per second, saying that it is your hard work! ”

This metaphor made Su Yuanshan laugh.

"Alright, stop whining. Help them get this lithography machine up and down well, and they will have more money for the next one. ”

Li Mingliu pouted: "How much more can it be?" I heard that Nikon Canon costs hundreds of millions of dollars in research and development every year. ”

"Hehe, take your time, you have to have an understanding, as long as the lithography machine they are studying can achieve yield on a certain line width, then there must be a market - can't make high-end, can't you make low-end? In the future, with the development of the semiconductor industry, it will also drive a large number of electronic and electrical equipment, and all kinds of low-end ICs will definitely be in short supply. ”

"This is the lowest demand of the reason why we help Chengguang. ”

After getting into the car and waving goodbye to everyone, Su Yuanshan asked Zhou Xiaohui to show him the needs here.

I don't know if I don't look at this list, and I'm shocked when I see it.

Chengguang is really poor and crazy, in addition to high-precision parts such as motors and capacitors and inductors, which must be imported, even chip diodes have to be purchased by Su Yuanshan.

"Did we say there was no money today?" Su Yuanshan turned his head to look at Zhou Xiaohui.

Zhou Xiaohui pursed her lips and shook her head with a smile.

Su Yuanshan smiled: "Remember all the pens for them, don't miss a diode, when they dare not give money, we will directly pull the machine back." ”
