Chapter 232 Turning On the Evaporation Machine

Compared with the lithography machine, the vapor deposition machine is very large in size, with a length of more than 100 meters. It is basically an assembly line. If it is a small workshop, it cannot be opened at all.

During the coating process, the panel will move back and forth in the entire evaporation machine, and when it comes out, the coating has been successful.

With the development of the times and the continuous updating of electronic products, our demand for OLED screens is also increasing, reaching an astonishing more than 5 million pieces in just one year. There is no doubt that as time goes by, this number will increase. will continue to rise.

Because we are very short of evaporation machines for making screens, the number of screens we can manufacture is actually very small, which cannot meet the needs of our market at all, let alone sell them to foreign companies.

In order to meet the needs of our huge screen, we can only import from abroad, resulting in a lot of money flowing out.

So far, there is only one Canon Tokki vapor deposition machine in our whole country. Even if this Canon Tokki vapor deposition machine is turned on 24 hours a day, it cannot meet our needs.

I seriously doubt that the purpose of selling us this Canon Tokki evaporation machine is to disgust us.

If we sell two of them, we can disassemble one for reverse analysis, maybe after years of research, we can perfectly manufacture the vapor deposition machine, and even in individual performance, we may surpass Canon Tokki vapor deposition machine. Plating machine.

But one, to be honest, are you willing to dismantle it?
What if it is disassembled and cannot be installed?

Call someone to fix it?

Everyone is in this industry, so you can understand what's going on at a glance. After knowing the whole story, what if the other party doesn't want to fix it for us?
Now the production of screens is basically dominated by Samsung, and Samsung is also proud of the screens they produce.

But this is only superficial, and the most terrifying thing is the island country, because they manufacture the key equipment for the production of the screen, and the materials for the production of the screen are purchased from the island country.

No matter how you look at it, it looks like the South Bangzi country found by the island country.

Although the words are not pleasant, Nanbangziguo will definitely not admit it, but the fact seems to be the case.

This time Zhang Xingchen wants to enter the vapor deposition machine industry, which is directly aimed at the high-end vapor deposition machine industry. For Zhang Xingchen, it is meaningless to manufacture low-end vapor deposition machines now.

In fact, Zhang Xingchen entered the screen industry and the vapor deposition machine industry not only because he wanted to make money, but of course making money is a very important factor.

On the other hand, it is to break the monopoly of other countries on the screen and the monopoly on the evaporation machine, so as to truly achieve independence and not be stuck by the other party. This is the most important thing.

Evaporation machines have very high requirements for materials and precision, but compared with photolithography machines, they are still a little bit worse, which is not difficult for Xiaobai at all.

Xiaobai directly mobilized the main force of the robots, and led a total of fifty robots to work together, busying around in a super-large workshop.

Strive to manufacture the vapor deposition machine in the fastest time.

The working environment of the evaporation machine must be in a vacuum state, and then the coating material is heated, and the island coating material is vaporized, and then the vaporized coating material is evenly attached to the substrate to form a thin film.

It's easy to say, but hard to do, and the truth is understood...

During this period, Zhang Xingchen naturally participated in it, in order to understand the products produced by his company.

After a month of hard work, and finally with the concerted efforts of everyone, they finally manufactured their own vapor deposition machine—the star vapor deposition machine.

"Compared with the Canon Tokki evaporation machine, our star evaporation machine has the following advantages. First, our length and volume are smaller. The Canon Tokki evaporation machine is 100 meters long. Our star Canon Tokki evaporation machine only has 70 meters long, concentrated is the essence."

"Secondly, our error is smaller, because we have manufactured a lithography machine, and we have diverted part of the requirements of the lithography machine to manufacture an evaporation machine. Our error can achieve evaporation of organic materials onto the substrate. The effective error on the panel is kept within three microns, which is equivalent to three percent of our human hair."

"As for the Canon Tokki evaporation machine that can only achieve five microns, don't underestimate the difference of only two microns, which is a qualitative difference."

"This represents the technological gap and technological generation gap. The islanders tried every means to improve the precision, but they all ended in failure. Now they can only achieve five microns."

The production is not finished yet, and the vapor deposition machine needs to be debugged, so that each part of the parts can be seamlessly matched with each other and reach the best state, just like the debugging of a car.

There is also the need to find out the shortcomings or defects of the current evaporation machine, and then improve and strive for excellence.

Strive to make the evaporation machine reach the best condition.

In the following week, Zhang Xingchen and Xiaobai were adjusting the vapor deposition machine, and finally in a week, the vapor deposition machine in front of them had reached the point where there was no air conditioning.

"This is the best evaporation machine we can make so far."

Zhang Xingchen wiped the sweat from his face. His eyes were already bloodshot. With Zhang Xingchen's physical fitness, his eyes were bloodshot and his face was exhausted. This shows how heavy Zhang Xingchen's workload is. .

But apart from the bloodshot eyes in Zhang Xingchen's eyes, there was also...excitement.

That's right, it is.

The vapor deposition machine is the mechanical equipment that Zhang Xingchen has participated in for the longest time. Zhang Xingchen wants to see with his own eyes how the vapor deposition machine is after he participated in the research.

"Carry out alcohol disinfection." Zhang Xingchen said, for the vapor deposition machine, it must be disinfected first to eliminate the bacteria inside.

"Proceed to the next step, prepare to open the inflation valve and inflate it."

Here is the air inside the bell jar.

"Turn on the water inlet switch and the water outlet switch."

The function of the water here is cooling.

Then it is necessary to pump air. What needs to be used is a vacuum pumping system, which needs to maintain a vacuum environment.

The entire vacuum pumping system is very complicated, consisting of pressure gauges, vacuum gauges, rough vacuum pumps, high vacuum pumps, valves and a series of pipelines.

The most important of these are rough vacuum pumps and high vacuum pumps.

Here, the high vacuum pump is DO2W molecular pump, and the high vacuum pump is turbo mechanical pump.

"Close the inflation valve."

"Close the high vacuum valve."

After the valve is closed, you can pump air.

Of course, the vacuum mentioned here certainly cannot reach the absolute vacuum in space. In fact, as long as the atmospheric pressure here reaches 10-2 power Pa, it can be declared over, and we believe that the vacuum state has been reached at this time.
