Listening to Lin Xiao's words, everyone present couldn't help but look at each other.
Does that seem reasonable?
Even machinists like them, who have been engaged in manufacturing such high-precision mechanical instruments for countless years, have to admire Lin Xiao's eight-point structure.
In particular, the machinist in front of Lin Xiao who looked to be in his fifties was called Huang Yaping. He was trained by an eighth-level fitter.
In China in the last century, eighth-level fitters were all boss-level people. But later, more sophisticated machine tools replaced the role of eighth-level fitters, so now these names are basically unknown, but if you have these
Technical people are still rare talents in the industry.
Huang Yaping, who was once an eighth-level fitter apprentice, later studied various machine tools carefully, and has now been awarded the title of researcher-level senior engineer, which is a senior at the same level as a professor. He is very skilled.
He was solid, so he was able to be selected by the X-ray plan and responsible for the main assembly work of the X-ray lithography machine.
And even he admired Lin Xiao's original eight-point structure. This achievement alone was enough to make Lin Xiao a great figure in their mechanical world.
However, they are still a little worried.
Although the eight-point structure is indeed very powerful, can Lin Xiao really work as a machinist?
The eight-point structure is about R&D capabilities, but their current assembly work is about hands-on capabilities.
In their opinion, the best thing for people like Lin Xiao to do is to do mental work at the desk, and then develop a methodology that can solve the problems they face. Then they, the working people, follow the instructions in his methodology.
, and finally solved the problem.
Seeing that everyone present still looked unbelieving, Lin Xiao rolled up his sleeves and said, "It seems I have to show it to you once."
He turned around and looked around, and saw a square metal block next to him. Then he picked up the metal block, pinched it, and squinted his eyes to look at it carefully.
People around him couldn't help but wonder, what is he doing?
After a while, Lin Xiao said: "This thing is 3.234 centimeters long, 2.251 centimeters wide, and... 1.324 centimeters high. Well, the error should be about three strands."
After hearing the data reported by Lin Xiao, everyone present was stunned.
Lin Xiao, can you directly tell the length, width and height of this piece of metal?
Of course, seeing the length, width and height is nothing. Huang Yaping himself can tell the length, width and height of this metal block with his naked eyes.
However, the extent he can distinguish is to one decimal place of a centimeter, which is the extent of millimeters.
He can distinguish a difference of up to 1 millimeter, while some more powerful people can distinguish a difference of less than 1 millimeter, or even 0.5 millimeters.
But Lin Xiao, what is this?
Three decimal places?
This is down to one hundredth of a millimeter!
It is equivalent to the level of "silk".
A thread refers to 10 microns, which is one hundredth of a millimeter, and Lin Xiao said that the error is about three threads. In other words, he can distinguish things of 30 microns?
Are these... still human eyes?
Everyone around him showed doubtful expressions. Even Yang Kaiping looked unconvinced. If Lin Xiao hadn't been the chief designer, they would have said he was bragging.
And Huang Yaping shook his head directly and said: "Impossible, absolutely impossible!"
"Chief Master Lin, we know that you can draw very accurately, but you are so silk-like, the human eye can't do it, right?"
He has been working in the machinery industry for who knows how long, and he has seen a lot. He has seen people who can directly distinguish 0.1 mm, which is 10 wires, with the naked eye. There are also many experienced machine tool workers who can rely on the feel of their hands.
Directly cutting or erasing one or two strands, he himself can control it to a few strands with the feel of his hand, but the feel of the hand and the naked eye are completely different. The latter tests the limits of the human eye, and it is also difficult to distinguish with the naked eye.
Experience required.
Lin Xiao is not an experienced technician who has been immersed in their machinery industry for many years. How could he be able to distinguish three threads with the naked eye?
Lin Xiao said with a smile: "The human eye can see things at a minimum of about 10 microns, which means that the human eye can theoretically directly distinguish every strand. I have only reached three strands."
Then he handed the metal block in his hand to Huang Yaping and said, "You should have a micrometer caliper here, right? Just test it."
Huang Yaping still couldn't believe it. When he saw Lin Xiao handing it over, he took it, then picked up the digital micrometer caliper next to him and started measuring.
The first is length.
Fortunately, the metal block did not exceed the measuring range of the digital micrometer caliper in his hand, so it just fit in.
And soon, because it was a digital display, the result came out directly, "It's...32.32 mm!"
As soon as this number came out, people who had just shown expressions of disbelief were shocked. They all came up and took a look at the displayed number. It was indeed 32.32 millimeters, which is 3.232 centimeters!
What Lin Xiao just said was 3.234 centimeters, and the error was only... 2 wires!
Even though they are all well-informed, they couldn't help but smack their lips at this moment.
Isn't this really too perverted?
Huang Yaping took a deep look at Lin Xiao, then lowered his head again and continued to measure the width, "The width is...22.52 mm."
There is only a slight difference from the 2.251 centimeters that Lin Xiao just said.
If the first time can be said to be luck, then can this second time be said to be luck?
the third time.
"The height is 13.21 mm."
Huang Yaping quickly measured his height.
It's three inches off from the 1.324 centimeters Lin Xiao said, but it's still within the error Lin Xiao said.
For a moment, everyone was silent.
But Lin Xiao quickly broke their silence: "Is the head office now?"
Huang Yaping smiled bitterly, then extended a thumbs up to Lin Xiao and said: "General Master Lin, I have never convinced anyone before. Today you have completely convinced me. I read on the Internet that you are almighty. I used to say that you are almighty."
I didn’t believe it, but now I see that you are really all-powerful.”
Lin Xiao laughed and said: "It's not enough to be omnipotent. For example, in biology and informatics, I haven't made any achievements yet."
"You don't have to be modest." Huang Yaping waved his hand and said: "Now if you are sure to stay, then I will definitely have nothing to say. With your eyes that can distinguish three silks, I don't know how many measurements we will be saved in the future.
The time it took was originally early September, but now I estimate it will be fine in mid-August."
Measurement is a time-consuming thing, but it has to be done, especially their current work, which inherently requires a lot of measurement work.
And now that Lin Xiao is here, I don’t know how much effort it can save them. Although Lin Xiao’s visual discrimination error is still about three strands, it is still very helpful to them.
So now Huang Yaping is confident that it will be completed more than ten days ahead of schedule.
Lin Xiao also smiled and said: "Okay, this time has satisfied my requirements, let's start working now?"
Seeing that General Master Lin was so active, Huang Yaping smiled and said, "Okay."
Then, Lin Xiao directly joined their work, and after that, his amazing naked eye resolution played a huge role in the future, unless it was the kind of work where the accuracy must be below three wires.
They also need to use professional instruments to measure. Other times, Lin Xiao basically does what he says.
Suddenly, their speed also increased a lot.
As for Yang Kaiping, who came with Lin Xiao, he was full of helplessness. He didn't expect that their chief engineer Lin would do this kind of manual labor himself, but there was no way. Top mechanics like Huang Yaping were really hard to find.
They do have some shortages in manpower.
However, Yang Kaiping was still a little confused, why was Lin Xiao in such a hurry?
Seeing Lin Xiao entering work, he asked this question.
Lin Xiao replied: "I hope we can use our photolithography machine to manufacture our chips during the National Day."
Yang Kaiping was stunned, National Day?
Then he understood what Lin Xiao meant, and it was indeed something worth doing to send this gift to the country on National Day.
So he said: "I know, I will tell other people, as well as the people in the software department, about this news and ask them to speed up."
"Um."
Lin Xiao nodded, then said no more and continued to do his work.
And Yang Kaiping no longer stayed here, and went to inform Lin Xiao that he planned to officially manufacture the chip during the National Day.
Especially the software department.
The software department is working hard to develop their lithography machine operating system.
It's not enough to build a lithography machine, you still have to develop an operating system.
So, now we just wait for these two carriages to reach the terminal together.
…
Time passed in an instant.
Looking back at the proof of Hodge's conjecture, it seems like it was still in the previous chapters.
As a prover, Lin Xiao brought along a Fields Medal winner. The time after the International Congress of Mathematicians was originally the period when interest in him was at its strongest.
However, people discovered that at this time of the limelight, Lin Xiao was completely missing.
If it were another person, how about a don't laugh challenge first?
Or you can directly bring goods through live broadcast and come to Pangajiao.
However, Lin Xiao never appeared and the media could not be contacted. Except for CCTV's interview with Lin Xiao, which added a famous scene to the Internet, other media who wanted to interview Lin Xiao had no choice but to give up.
As a result, this period of heat gradually subsided.
The day has also arrived in August.
August 15th.
…
In the dust-free workshop of the Dingguang Research Institute, five boxy instruments stand in the middle. Each instrument occupies an area of about 5m*2m and is 4m high. Compared with the occupied area of Asmail's EUV lithography machine,
The area is smaller, but the height is higher, because compared to the complex optical path of the EUV lithography machine, the X-ray light source optical path is simpler. After all, X-rays cannot be refracted like EUV light, so the X-ray source is straightforward to install.
In the past, it was just that the X-ray source generator needed to be installed on it, so the height was much higher.
At this time, a technician was operating the machine and installing the last aluminum plate wrapped with a lead plate.
At this point, all five X-ray lithography machines were born.
At the same time, every X-ray lithography machine has a shell with an "X" printed on it.
Simple, but it makes people feel the cutting-edge technology hidden in it!
