Rebirth of Northland 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, 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 terrifying figure of 2.1 million!

Such a large workload, 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 will not be possible to complete.

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

The industrial-related majors of the University of Technology, especially in the field of traditional mechanical processing, are very strong.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 the campus, people often greet him, but he does not know each other.

"Pork 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, 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?

"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.Not to mention, as long as the projects he participates in, without discussing 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, it is still unknown whether the paper can be published.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 been fully automated.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.

Automating 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, the detection accuracy of the sensor will be required to be less than micron.Traditional sensors of this level are costly!

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 cause of huge investment in the semiconductor industry.

With the point of view of later generations, Cheng Yongxing saw 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, which 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.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 lot of fixtures.Through the combination of manpower and fixtures, the purpose of low cost and high precision is achieved.Semi-automatic human-moving equipment replaces fully automatic operation 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.

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 in line with the current situation of the domestic equipment industry.

Since in the field of automation control, the domestic is more than one era behind the foreign countries, then the operation is carried out 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 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 ready 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 needed 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.
