“Have the official reply been made?”

"Not yet, Mr. Wang."

It's been a month!

Wang Anran shook his head. He had made up his mind that no matter what the official attitude was, he must continue to do this matter and must be under his leadership.

He was mentally prepared that the lithography machine was a bottomless pit and might lose a lot of money in it.

But will Wang Anran care about money? In fact, Wang Anran is more prosperous than Ma’s father now, and he is really not interested in money.

Even if the house is full of money, there are only a dozen or so in the bank account, and there is no sense of accomplishment.

In Tianjin Port, three chip production lines from ibm have been declared and entered the port, and two of them have been directly pulled down to the newly built factories.

Another one, Huaxin Technology directly contracted the next warehouse, carried out dust-free and anti-static transformation of the warehouse, and brought the required equipment to functionally partitioned.

Here, this chip production line will be completely disassembled and drawn into drawings.

Chief Engineer Guo Haocheng said: "Mr. Wang, if this production line is removed, it may not be able to be used even if it is installed again.

Especially the lens group is dust-free and sealed. After disassembly, we cannot guarantee that it will not be contaminated."

There are more than twenty different concave lenses and convex lenses in the lens group, and the light filters the flat glass.

If these lenses are used to take photos, there is nothing wrong with them. 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 concerns, which made Wang Anran very dissatisfied.

"Professor Guo, why don't we take this opportunity to study the installation of the Chen Wu Assembly? Could it be that if we produce lenses in the future, we will ask foreigners to help us install them?"

This was a bit heavy, and Wang Anran said it a little annoyed. In front of so many people, Guo Haocheng was a little unable to get out of the way.

"Mr. Wang, I..."

Guo Haocheng is the chief engineer who was poached by Huaxin Technology from Shanghai Precision Manufacturing Instruments Company. Like many engineers, his language expression ability is their natural shortcomings.

Wang Anran looked at him and said, "Professor Guo, this time we are giving us a chance to learn, so each of us must be nervous. This is not what we say to you, but to everyone..."

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

Huaxin Technology has made sufficient preparations for the disassembly of the lithography machine this time, which are divided into seven major pieces and dozens of small items.

The first piece is disassembly, referring to the equipment instructions and maintenance manual provided by ibm. However, if you want to remove this equipment without loss, you still need to do a lot of homework.

The first thing the disassembly group needs to do is number the parts, start from the peripheral auxiliary parts, and take the whole process before and after the disassembly.

The second part is the measurement group. What you need to do is not only high-precision measurement of parts, but also spectral analysis of materials.

Most of the members of the optoelectronics group were drawn within Huaxin Technology and were responsible for analyzing and testing control chips, integrated circuits and sensor systems, which required corresponding photoelectric physics support.

There are also support from machinery, chemistry, and materials science.

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

This also made this task more difficult.

First of all, the disassembly plan was delayed, so Wang Anran held a special promotion meeting for this.

Guo Haocheng was under great pressure. This task not only disassembled the equipment completely, but also needed to be installed and restored after surveying and mapping. The test just now showed Mr. Wang's attitude, which made him even more nervous.

Think about it, this is a device worth tens of millions of dollars?

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

Zhou Dongjun, the leader of the disassembly team, said: "Mr. Wang, our disassembly team found in the combination of equipment and research related materials.

Some core areas are locked, such as pneumatic bearings and optical component assembly. We cannot disassemble the damage-free, and can only destroy some devices..."

Wang Anran said: "Find out the principles and functions, simulate them first, and there is really no way to violently disassemble them. We must see what it looks like inside!"

"Mr. Wang, then..."

"What I said just now is not that failure is not allowed. I mean, during the disassembly, let's ask more why.

Why do people design this way? What are the benefits and disadvantages of designing this way? We need to summarize our own ideas, whether it is design, manufacturing or installation, in all aspects."

Li Yuehua, the leader of the optoelectronics group, said: "Mr. Wang, we lack equipment to test control code for the control chip. If we can find 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 data and feeds the information back to the control chip through the data interface. Then the control chip transmits the control command to the mechanical control system according to the pre-written program. The mechanical presses and then follows the instructions, and then repeats this process.

Wang Anran understood very well that control chips and codes are not the key. After understanding the principles, Huaxin Technology can design control chips and compile relevant codes by itself.

The difficulty is the parameters, such as the driving lens moves by five millimeters, how much voltage is given by the corresponding servo motor, how to compensate for the chip deviation after moving, etc.!

This requires thousands of debugging and revision of parameters again and again.

This is hard skill, and it cannot be avoided in precision manufacturing.

"In terms of Canon, the company can coordinate and do not guarantee success. In the end, we still have to base ourselves on ourselves, and there is nothing to say!"

Each group raised many difficulties, and the core idea was: it was too difficult and it was not guaranteed to be broken.

Wang Anran is naturally not afraid of you breaking it. What he is afraid of is that after finishing it, he still knows nothing.

"Huaxin Technology has three such devices. Even if it is broken this time, it doesn't matter. We should pay the tuition fee.

If one is not enough, then we will dismantle the second one. If the second one is not enough, then we will dismantle the third one. But if the third one is finished, we still don’t know the design, manufacturing, and installation techniques, then I will ask everyone if they are careful..."

…………

At the same time as the disassembly task, Wang Anyran proposed a new task to Huawei Software.

This surveying and mapping is not just left on paper. Wang Anran’s idea is to install this chip production line into a computer.
