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

When it came to the discussion of the control system, Li Mingliu and others from Yuanxin also joined in. Then it was over. The discussion of statistical needs was originally turned into a purely technical discussion.

During this period, Zheng Zhenchuan wanted to remind these people to be careful not to go off topic, but when he saw Su Yuanshan listening quietly and interestingly, he even picked up his laptop and kept writing and painting before giving up.

Just as the engineers from Chengguang Institute were about to go to get the drawings for the second time, Su Yuanshan raised his wrist and looked at the time.

"Well...why don't you stop first?" Su Yuanshan raised his notebook and smiled: "My teachers and seniors, I have roughly remembered that in order to achieve the ideal alignment system solution, in addition to micromotors, it seems that there are also many models of optical diodes required? In addition, I heard from Lao Liu that I would also need to redesign the PCB of the control circuit."

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

"Especially, precision instruments like lithography machines require long-term verification just for heat dissipation and anti-interference. Zheng Zheng, do you think so?" Su Yuanshan said and asked Zheng Zhenchuan with a smile.

Zheng Zhenchuan smiled meaningfully and nodded: "That's right. Lao Zhou, don't argue with Mr. Li."

Lao Zhou is an old engineer in his forties and has been responsible for various circuit designs of the alignment system here. To be honest, he has a lot of complaints about Zheng Zhenchuan calling private companies like Yuanxin to come and help... and he almost completely denied his previous work, which made him really unacceptable. So in the past two months, he and Li Mingliu's team have been working together, striving to innovate and iterate based on the original circuit design.

But he didn't expect that Li Mingliu would reiterate the old words after the boss came today. How could he tolerate this?

Old Zhou snorted softly: "Director Zheng, it's not a matter of whether to fight or not. The thickness of the circuit board such as a lithography machine will affect the overall accuracy. How can it be done again? It's better to start the design of the entire machine again."

"It's OK." Li Ming and Liu Zhengfeng said to each other: "Zhu Jianting's mechanical cad has been in operation for half a year, and the beta version can be produced in the second half of the year at the latest. Then you can take it over and draw it again - Mr. Chen, your design team will not have to use a magnifying glass to look at the drawings every day."

The middle-aged man who called Mr. Chen coughed.

Su Yuanshan was so amused that he covered his mouth and coughed.

He knew that Li Mingliu was a kind of person who was completely arrogant even at T-U. After entering Yuanxin, he was finally subdued by himself and Xi Xiaoding, but it did not mean that he was really not arrogant. Others were afraid of hearing the Institute of Optics of the Chinese Academy of Sciences, but it depends on what field it depends.

I won’t talk about the mechanical and optical parts, that’s their field, which is awesome. But the IC and circuit parts are Li Mingliu’s field, and Li Mingliu still participated in the development of EDA simulation tools throughout the process. In this part, he is a well-deserved expert.

Seeing Su Yuanshan reminding, Li Mingliu also knew that he was a little sharper and immediately said earnestly: "Old Zhou, really, listen to me. If you are worried about the size, we can leave a blank space, but the thing before was really not good - Yuanxin's vcd board was designed by me personally, and it was reduced from the size of the plate to the size of the dictionary. Do you think I'm awesome? Tell me! That's a cheating laymen!"

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

"Our design relies entirely on EDA simulation. You said, how do you design the board? Can you catch up with the simulation tool of Yuanxin?"

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

Su Yuanshan looked at Zheng Zhenchuan and saw that Zheng Zhenchuan smiled like nothing happened: "It's okay, it's all for work, just quarrel. Don't watch Chen drinking tea over there, when he first designed the drawings, he was more quarrel than anyone else."

Zheng Zhenchuan said and said with a straight face: "Okay, today we will make a complete decision while Mr. Xiao Su is here too. All circuits will be redesigned."

The person in charge of statistics on the side asked immediately: "Will there be any changes in the components? Do you need to purchase new ones?"

"I'll design it first. Today you can sort out what we need urgently at this stage."

Zheng Zhenchuan waved his hand and gave a summary of today's meeting.

Su Yuanshan refused Zheng Zhenchuan's retention and farewell, and only asked Li Mingliu and others to send him to the parking lot. Shen Haoran had decided to join Yuanxin here, so the few were all his own people.

"Mr. Shan, did you see it?" Li Mingliu smiled bitterly: "When I was a child, I thought the Academy of Sciences was so mysterious and great, but I realized it after getting close... Alas!"

Shen Haoran smiled and took the lead for the lithography machine department and said: "The electronic tube technology that the military industry has been following before is mature and reliable. Although we are chasing the semiconductor industry, lithography machines are now mainly in greater demand for civilian equipment, so the investment is relatively less, and we really have no money, so we are used to QQ Sosuo."

"It's because of poverty that you have to think about change! You can't say that you have worked hard to create a powerful abacus that can calculate 100 times a second under the difficult conditions. You just need to put a calculator that can calculate 10,000 times a second. You say that it's your hard work! That's not a big deal."

This metaphor made Su Yuanshan laugh.

"Okay, don't complain. Help them get this lithography machine well and do it better, and they will have more funds for the next one."

Li Mingliu pursed: "How much more can you do? I heard that Nikon Canon costs more than 100 million yuan per year, or is it still US dollars."

"Haha, take it slowly, you need to have an understanding. As long as the lithography machine they are studying can achieve yields on a certain line width, there will definitely be a market - you cannot create high-end ones, can't you still create low-end ones? In the future, with the development of the semiconductor industry, it will also drive a large number of electronic and electrical equipment. At that time, various low-end IICs will definitely be in short supply."

"This is the lowest demand for us to help Cheng Guangshu."

After getting in 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 read this list, and I’m shocked when I see it.

Chengguang Institute is really crazy. In addition to high-precision components such as motors and capacitor inductors that need to be imported, even chip diodes, Su Yuanshan needs to help purchase them.

"We said there was no money today?" Su Yuanshan turned his head and looked at Zhou Xiaohui.

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

Su Yuanshan smiled and said, "Remember all those pens for them. Don't miss a diode. If they dare not give money, we will just pull the machine back."
