Chapter 149 Miracles
Chen Quan has never been in contact with mechanical drawing, so every time he draws a few strokes, he must close his eyes to "memory".

Fortunately, 'his' memory is complete.Under the surprised eyes of everyone, Chen Quan's technique quickly became proficient at a speed visible to the naked eye.

A clear three-dimensional view gradually takes shape on the drawing board.

Although everyone was very puzzled by the strange phenomenon in front of them, their eyes were gradually attracted by the content of the blueprint itself.

"Such a large quartz jar?"

Looking at the dimensions just marked on the drawing, Wang Qingshan started to have a headache again.

In MOCVD, since the workpiece in the cavity needs to be heated, the tank body is generally made of quartz material, which can be heated by infrared or electromagnetic means.

The biggest problem with quartz materials is that the processing performance is extremely poor. Conventional processing methods, such as vise washing, planing and grinding, cannot be used.In most cases, it must be cast in one shot.

"Can we do it? It feels so choking!"

As time passed, more and more technicians rushed over, and they all gathered behind Chen Quan to watch what was new. "No wonder this thing is embargoed. Only with this high-temperature-resistant large glass jar, there are not many domestic processing conditions."

"No, the tank can be made of stainless steel. No quartz."

Chen Quan marked it on the drawing.

"Stainless steel? How do you solve the heating problem of the workpiece in the chamber?" Wang Qingshan asked. "Electromagnetic or infrared methods are unusable, and metal will shield both types of radiation."

"Using the method of heating in the cavity."

Chen Quan quickly completed an enlarged section view.

"The cafeteria is ready. Do you want to eat first?"

Secretary Liu ran in.

"You go. I'm going to finish the picture."

Chen Quan's painting became smoother and smoother, and he couldn't bear to stop.Another reason is that I am afraid that the memory of 'him' will be fleeting.Although 'his' memory is very reliable, but who dares to bet that accidents will not happen?
"Go and inform the cafeteria, and the food will be served later." Liu Minxue ordered.

If Chen Quan doesn't leave, it's hard for others to leave either.

"What is this?"

As time went by, more and more details were added to the drawings.

"This is a rotary table. The workpiece is constantly rotating on the table. In this way, the uniformity of the surface of the workpiece is improved. This is a sub-cavity. The function of the sub-cavity is to create Create a small low temperature zone and reduce the heat resistance requirements for the mechanical transmission part”

Chen Quan kept explaining while drawing.

'His' MOCVD includes a large number of innovative designs: metal tank body, sub-cavity, self-heating workbench, rotating workbench, double nozzle structure, etc.

At two o'clock in the afternoon, when Chen Quan finally put down his pencil, an extremely complicated structural diagram was completely presented in front of everyone.

"I won't mark the tolerance or something. You can handle it yourself."

Chen Quan patted the pencil dust on his sleeves, stepped back in satisfaction, and looked up and down.

Cafeteria
Because of Chen Quan, the working meal was more than two hours later than expected. Everyone was starving, and they ate very fast.

When everyone was almost finished eating, Liu Minxue found a chance to speak.

"To be honest, when you didn't come, Chen Quan, I always thought that the reports about you were mostly propaganda. But after seeing it with my own eyes just now, I realized that those news reports were not exaggerated, but rather too modest. "

Although Liu Minxue was flattering, everyone nodded unanimously.

Although there are people from the sales department present, most of them are extremely proud senior intellectuals, such as Wang Qingshan from the technical department.In the eyes of these people, technology is technology, very simple.

In less than four hours, under the watchful eyes of everyone, Chen Quan completed the design of a large-scale international cutting-edge equipment.

Although the efficiency of the scientific instrument is not good, there are new college students assigned every year.When the new employees first came, they could only start by playing and dismantling some simple parts diagrams.It is impossible to get started with such a large-scale equipment design without ten years of basic skills.Not to mention, in the absence of a reference design at all.

In addition to the complexity of the equipment, there is also the degree of perfection.

Any new equipment requires multiple iterations and improvements before it can mature.But under Chen Quan's pen, all the dimensions are completed in one go, with very little rework and modification in the middle.

During the process of drawing the drawings, Wang Qingshan and others asked many questions, which were all answered casually by Chen Quan.It makes people feel that all the details of this design have been carefully thought out.

Not to mention the brand-new technology of MOCVD, it is just an ordinary equipment. It is not easy to achieve this.

If not everyone is a believer in materialism, I am afraid that someone will shout "miracle" on the spot.Chen Quan's name can be preceded by "Holy".

"Yeah yeah!"

Wang Zhan followed suit. "Although I don't know much about mechanical design, I know that just such a large zero-scale drawing can be copied by others, and it won't be able to be copied in a day."

When everyone heard it, they found that it was indeed the case.

Even if the technical difficulty involved is not taken into account, it will take 2-3 days for a drawing of No. [-] to be handed over to a dedicated tracer (to convert the white drawing into a sulfuric acid paper drawing, so that it can be subsequently printed into a blueprint).

"Yes, yes."

Section Chief Sun, who was in charge of sales, finally found the opportunity to speak. "This drawing of yours doesn't look like a drawing at all to me."

"Oh? How do you say it?" Someone cheered.

"How could this blueprint be designed by someone? It was created by magic!"

Chief Sun's eyes were wide open, and his expression was exaggerated.

"Don't believe it? Looking back now, do you think you are dreaming? Can such a complicated and advanced equipment be completed within a few hours? This is simply impossible!"

Section Chief Sun's actions made everyone at the scene laugh.

But after the laughter, everyone suddenly found out that Section Chief Sun was telling the truth!

Everyone here has at least a bachelor's degree and knows the level of college students, especially freshmen.

Chen Quan, a freshman who has never studied mechanical drawing for a day and never touched a drawing board, drew a complete MOCVD structure diagram under the eyes of everyone.

"Well, this drawing is detailed enough. Can you process the MOCVD I want?"

Chen Quan's words awakened everyone who was deep in thought and doubted their lives.

"Yes, yes! Absolutely no problem."

Wang Qingshan finally gave an affirmative answer.

Although Chen Quan only provided the general assembly drawing, there is still a long way to go before it can be processed in the workshop.But the follow-up demolition work is not so difficult.

After returning to the meeting room and sitting down again, Wang Zhan took the initiative to stir up the topic. "Chen Quan, you have been to many places, and you have seen more foreign equipment manufacturers than all of us. Tell me, what is the main difference between domestic and foreign equipment manufacturers?"

It is extremely rare for Chen Quan to be able to sweep all the equipment factories in Europe.Due to the nature of his work, Wang Zhan doesn't have many opportunities to go abroad, and he doesn't have the opportunity to visit equipment manufacturers in depth.

In addition, Wang Zhan had also vaguely heard of the magical legend of Chen Quan, that is, Chen Quan's eyes are more powerful than the camera.Chen Quan's eyes can penetrate the shell of the equipment and directly understand the advanced technology contained in the machine.

In the past, he dismissed such claims.But today, believe it or not.

That MOCVD can't be done well is where Chen Quan saw it.Otherwise there is simply no way to explain what happened today.Chen Quan was like a soul possessing a body, and suddenly changed from a layman in mechanical design to an expert in equipment design.

"Well. I've been to too many factories and seen too many things. I don't even know where to start." Chen Quan did not refuse.

"It's okay, just talk about it." Liu Minxue and others said it easily, but they all took out their pens and paper.

"Let me first talk about my feelings in general. Compared with foreign equipment manufacturers, domestic equipment manufacturers are two generations behind in technology. The main reasons are two points.

The first point is the condition.

As far as drawing and drawing is concerned, foreign equipment manufacturers have long popularized CAD/CAM.On each designer, their hardware investment is no less than $10.In our country, even a magnet-style drawing board with a level of seven or eight hundred yuan is still regarded as a treasure.

CAD/CAM software brings engineers and technicians not only convenient conditions, but also a way of thinking.For most of the parts, after the dimensions are input, the 3D model can be displayed on the computer in real time.This is greatly enhanced."

When Chen Quan said this, he suddenly stopped.

"What's wrong with you?" Qu Yanqiu poked him beside him.

"What Chen Quan said is very reasonable. The technology of our equipment manufacturers has lagged behind in recent years, most of which are due to the constraints of conditions and markets. And conditions and markets complement each other."

Wang Zhan thought that Chen Quan's thoughts were stuck, so he took over the conversation. "Without the market, there will be no profit to improve our own conditions. Without conditions, we will continue to lose the market. This time we have a meeting in Beijing, and we have realized the relevant problems. Domestic semiconductor equipment manufacturers have completely lost their ability to generate blood.

OK, you go on. "

"Oh. The second point is vision."

Chen Quan shook his head and cut off a sudden thought.

"For domestic equipment manufacturers, because their competitors are also domestic counterparts, their thinking and vision are limited. This time we went to Europe and brought back a lot of technical information."
