"Has there been an official reply?"

"Not yet, Mr. Wang. ”

It's been a month!

Wang Anran shook his head, he had already made up his mind, no matter what the official attitude was, he must continue to deal with this matter, and it must be under his leadership.

He is mentally prepared that the lithography machine is a bottomless pit, and he may lose a lot of money in it.

But does Wang Anran care about money? In fact, Wang Anran is even more wealthy than Ma's father, and he is really not interested in money.

Even if the house is full of banknotes and there are more than a dozen zeros on the bank account, there is no sense of accomplishment.

In Tianjin Port, three chip production lines from IBM have been declared for customs entry, and two have been directly pulled down from the newly built factory.

On the other hand, Huaxin Technology directly contracted a warehouse, carried out dust-free and anti-static transformation of the warehouse, and moved the required equipment together for functional partitioning.

Here, the chip production line will be completely disassembled and made into drawings.

Chief engineer Guo Haocheng said: "Mr. Wang, if this production line is dismantled, even if it is installed again, it may no longer be used.

In particular, the lens group is dust-free and sealed, so we cannot guarantee that it will not be contaminated after disassembly. ”

There are more than 20 different concave lenses and convex lenses in the lens group, and the light has been filtered through flat glass.

If these lenses are used for photography, there is no, and if they can be used for chip processing, a grain of dust may block hundreds of transistors, and the yield rate cannot be guaranteed at all.

If the yield rate cannot be guaranteed, the entire production line will have no meaning of production.

Guo Haocheng expressed his concern, which made Wang Anran very dissatisfied.

"Professor Guo, why don't we take this opportunity to study the installation of dust-free assembly, do we have to ask foreigners to help us install the lens in the future. ”

This is a bit heavy, Wang Anran was a little annoyed as soon as he said it, in front of so many people, this made Guo Haocheng a little unable to get off the stage.

"Mr. Wang, I ......"

Guo Haocheng is the chief engineer of Huaxin Technology from Shanghai Precision Manufacturing Instrument Company, and like many engineers, their language skills are their natural shortcomings.

Wang Anran looked at him and said, "Professor Guo, this time is to give us a chance, an opportunity to learn, so each of us must be nervous, this is not for you, it is for everyone......"

Wang Anran felt that he couldn't speak......

This time, Huaxin Technology has made full preparations for the disassembly of the lithography machine, which is divided into seven major blocks and dozens of small items.

The first part is disassembly, which refers to the equipment instructions and maintenance manuals provided by IBM, but if you want to disassemble this device without damage, you still need to do a lot of homework.

The first thing the disassembly team did was to number the parts, starting with the peripheral auxiliary parts, and then taking pictures before and after the disassembly.

The second part is the measurement group, which is not only to measure the parts with high accuracy, but also to analyze the spectral analysis of the materials.

Most of the members of the optoelectronic group are drawn from Huaxin Technology and are responsible for the analysis and testing of control chips, integrated circuits and sensor systems, which requires the support of corresponding optoelectronic physics.

There is also support in mechanical, chemical, and materials science.

Everyone is very unfamiliar with the chip production equipment with the lithography machine as the core, and many people have never seen it once.

This also makes the mission more difficult.

First of all, in terms of the dismantling plan, it was delayed for a long time, and Wang Anran held a special promotion meeting for this reason.

Guo Haocheng is under a lot of pressure, this task is not only to completely disassemble the equipment, but also to install and restore the function after surveying and mapping, and a tentative sentence just now has shown Mr. Wang's attitude, which makes him even more worried.

Come to think of it, this is tens of millions of dollars of equipment?

But does Wang Anran care about tens of millions of dollars?

Zhou Dongjun, the leader of the dismantling team, said: "Mr. Wang, we dismantled the group, and found it in the combination of equipment and research related materials.

Some core areas are locked, such as pneumatic bearings, optical component assemblies, and we cannot disassemble them without damage, and can only destroy part of the device......"

Wang Anran said: "Figure out the principle and function, simulate it first, there is really no way to violently disassemble it, we have to see what it looks like inside!"

"Mr. Wang, that ......"

"What I just said is not that failure is not allowed, I mean, in the process of disassembly, we ask why.

Why do people design like this, what are the benefits and disadvantages of such design, we have to summarize our own ideas, whether it is design, manufacturing or installation, all aspects. ”

Li Yuehua, the leader of the optoelectronic group, said: "Mr. Wang, we lack the equipment to test the control code of the control chip, and if we can seek the machine code from Canon, I think the progress will be faster." ”

The control chip is generally combined with sensors, machinery, etc. to form a system.

The sensor detects the data, through the data interface, the information is fed back to the control chip, and then the control chip transmits the control instructions to the mechanical control system according to the pre-programmed program, and the machine operates according to the instructions again, and then reciprocates this process.

Wang Anran understands very well that the control chip and code are not the key, and after understanding the principle, Huaxin Technology can design the control chip and compile the relevant code by itself.

The difficulty is the parameters, such as the driving lens to move five millimeters, how much voltage the corresponding servo motor is given, how to compensate for the deviation of the moving piece, and so on!

This requires thousands of debugging cycles, revising parameters again and again.

This is hard work, and there is no way to avoid it in terms of precision manufacturing.

"On the Canon side, the company can coordinate, there is no guarantee of success, and in the end we still have to stand on our own, which is nothing to say!"

Each group put forward a lot of difficulties, and the core idea is: the difficulty is too great, and there is no guarantee that it will not be broken.

Wang Anran is naturally not afraid that you will demolish it, but what he is afraid of is that after the demolition, he still doesn't know anything.

"Huaxin Technology has three such devices, even if it is broken this time, it doesn't matter, we should pay this tuition.

If one is not enough, the second one will be dismantled, and the second one will not be enough, so we will dismantle the third one, but if the third one is dismantled, we still do not know the design, manufacturing, and installation technology, then I have to ask everyone, are you careful......"

............

At the same time as the dismantling task, Wang Anran proposed a new task to Huawei Software.

This mapping is not just a piece of paper, Wang Anran's idea is to install this chip production line into a computer.

He needed a large CAD software for lithography machine design.
