Rebirth of Northern Technology

And 1.25 million LEDs are just an ideal situation. Because the brightness of the three-color LED is not exactly the same. In this case, a combination is required.

For example, one pixel may need a combination of one red light, two green lights, and two blue lights. In this case, the total number of LED lamp beads has reached a horrible figure of 2.1 million!

Such a large amount of work, if you don't use some simple crafts and equipment to assist, I am afraid that everyone is really busy to vomit blood, and it is impossible to complete.

Cheng Yongxing also plans to outsource the design and processing of these simple process equipment.

The industry-related majors of the University of Technology, especially in the field of traditional mechanical processing, are very powerful. This makes a lot of work have support.

As soon as the message for help was sent out, there was an immediate response.

————————

"Xiaocheng!"

A young man broke into the office of photoelectric research.

"you are?"

Cheng Yongxing knew this unexpected guest, but he just couldn't remember who it was. Walking on campus, people often greet him, but he does not know each other.

"Pork wrapped in a pot, don't you remember?"

"Boiled meat?"

Cheng Yongxing was stunned. Why would anyone call this name? You can pack meat in a pot, and I still boiled fish!

"I asked you to eat pot meat, don't you remember me?"

This young teacher has been reminding carefully.

"Last time you ate with a group of classmates, it was in the small restaurant under the mechanical building."

"Ah! Come to think of it, you are... Tian..."

Cheng Yongxing finally remembered such a man. At that time, he invited his classmates to dinner, and this guy came to give him food. But why did he give away food at the time?

"I am Tian Xu. I didn't expect that we would meet again so soon."

Tian Xu looked at the young man in front of him with emotion. Time flies quickly, and the student in front of him has created the name of Connaught University in a blink of an eye. If nothing else, as long as the projects he participates in and don't talk about economic benefits, publishing papers is a piece of cake.

Time flies slowly again. Tian Xu's life is very difficult, and his thesis problem has not been solved yet. So as soon as he heard the news, he simply ran over by himself.

"Don't you need someone to help you design the fixture? This is my strength!"

Fixture design is a basic skill in the mechanical profession. With this design, it is generally impossible to publish a paper.

But the LED project is different, LED is now the outlet of the paper.

The white LED paper, to put it bluntly, is a phosphor application paper. Without the subject of LED, whether the paper can be published is still unknown. But with the LED attached, it became famous in one fell swoop.

Therefore, Tian Xu had high hopes for this project. He did not expect that the mechanical profession would have a day to be linked with semiconductors!

"Oh, I see. Let's go to the meeting room and talk."

In later generations, the equipment on the LED production line has achieved fully automated production. Cheng Yongxing once watched a video introduction, in the workshop, hundreds of fully automatic machines are working day and night. But in the entire workshop, there are only a few staff members who are constantly cruising and checking.

At present, it is obviously unrealistic to achieve such a high degree of automation. The prerequisite for a high degree of automation is highly developed image acquisition technology, image analysis capabilities, and high-speed computing capabilities.

These three conditions are not met now.

Automation in this era is a thankless process. For example, in the absence of image recognition technology, how to determine the absolute or relative position of the workpiece or manipulator?

If a traditional sensor is used, the sensor needs to be in contact with the workpiece, not to mention the possible pollution, but also puts forward extremely high requirements on the accuracy of the sensor.

For example, when chip cutting, if the cutting accuracy is micron level, then the detection accuracy of the sensor will be required to be less than micron. Traditional sensors of this level are expensive to counterfeit!

But in the semiconductor industry, it has become everyone's instinct to keep pace with automation. Without automation, how can high technology be reflected?

Another reason why manufacturers pursue high automation is that the production of semiconductor products is also relatively delicate. Any human factors will cause fluctuations in product quality.

This pursuit of a high degree of automation is also a major reason for the huge investment in the semiconductor industry.

With the point of view of later generations, Cheng Yongxing sees the so-called high precision now, with less awe and more calmness.

He intends to adopt a reactionary method used by BYD in later generations in the field of semiconductor production, that is, the manual fixture production line.

————————

BYD's starting point was the production of mobile phone batteries. Before BYD entered the market, the battery market was basically monopolized by Japanese manufacturers.

In that era, only Japanese manufacturers had complete automated production equipment. These devices are developed by Japanese manufacturers and rarely sold outside. Even if it is sold outside, the price is relatively high.

This kind of expensive automated production equipment brings high equipment depreciation costs. In addition, the actual operation of this equipment also places relatively high requirements on the technical level of the operators. Under these two points, the cost of battery production is almost the same everywhere in fact. It can't be done because skilled workers are hard to find and the cost is higher than in Japan!

But at this time, BYD suddenly emerged. The method they use is to use a large number of fixtures. Through the combination of manpower and fixtures, low cost and high precision are achieved. Semi-automatic human-moving equipment replaces fully-automatic operating instruments.

This method is more meaningful in the current era.

First, the cost of automation equipment is even higher. And labor costs are not cheap in general.

BYD can use this method to overtake Japan's battery industry and put it in the current semiconductor industry. Maybe it will also have a chance.

————————

In addition, the manual production line assisted by fixtures is also more in line with the status quo of the domestic equipment industry.

Since in the field of automation control, China is more than one era behind foreign countries, then we will operate in a different way. To bridge the gap in manufacturing process with more advanced design concepts.

This is similar to the original development idea of ​​the first generation of MOCVD. Through the process equipment and process flow of new ideas, the effect similar to that of the advanced or even two generation process equipment can be achieved.

After this, the industry chain can make itself blood, upgrade itself, and slowly climb the technological tree.

Optoelectronics research is preparing to establish such an anti-automated human production line in its own laboratory 15 years in advance. Its purpose is to produce the LED samples required by the large screen, and the other is also for mass production of the semiconductor industry in the future, to accumulate experience and find the possibility of overtaking in a curve.
