Chapter 199 The First Batch of IGBTs
The production of the first batch of high-power IGBTs has already started. These days, Tang Fei visits the production site almost every day, and today he arrived at the production site early in the morning.

If all goes well, the first finished IGBT should be successfully manufactured.

Sure enough, Zhao Ke came over now, holding the first produced IGBT, and put it on Tang Fei's desk.

Seeing this IGBT, Tang Fei became dissatisfied. He looked at it happily, and after looking at it, he said with satisfaction: "Well, it's really good, at least the appearance quality is top-notch."

Zhao Kedao: "Boss, it's far more than just top-notch appearance quality, its comprehensive performance is even top-notch."

This is the fifth-generation IGBT. Looking at the world, it is only found here. It is two generations ahead of the mainstream IGBTs on the market. The difference between the two generations is not good. It is no wonder that the performance is not good.

Coupled with the addition of Tang Fei's quality +1 BUFF, the quality of the produced IGBTs is top-notch, and Zhao Ke's mood at the moment seems to be even higher than Tang Fei's.

The first high-power IGBT has been successfully manufactured, which also makes Jiuzhou Industrial Co., Ltd. the first company in China to master the complete industrial chain of IGBT chip design-chip manufacturing-module packaging-system application, filling the domestic market. Gaps in related technical fields.

News spread quickly.

In the afternoon, many employees of Jiuzhou Industrial Co., Ltd. knew that their company had accomplished a feat, successfully producing the first high-power IGBT. No, many people were discussing this matter.

"It has been manufactured successfully, our company is really amazing!"

"I heard that it is still a high-power IGBT. The DJ4 electric locomotive of Hongxing Factory needs such a thing!"

"We can produce this thing, and I feel that when I go out, my waist will be much straighter."

"..."

It can be heard from the words of the employees that they are full of pride and joy.Yes, the first high-power IGBT was produced and filled the gap in the country in one fell swoop. What a thing to be proud of!

When Tang Fei was happy, he ordered Zhao Ke and others to produce several other high-power IGBTs. These types of IGBTs are all needed by the rail transit industry.

After a while, other types of IGBTs will be produced. Try to use one or two years to achieve serialization and familyization of IGBTs, covering the entire range from 600V to 6500V.

His first batch of high-power IGBTs were manufactured. Tang Fei went to the Red Star Factory in person and brought samples of this IGBT with him.

First go to Xie Zhenhua's office.

When he knocked on the door and entered, Xie Zhenhua was not there, and the door of the office was ajar. Tang Fei knew that Chief Engineer Xie must have gone to the final assembly workshop, and he probably went to personally pay attention to the assembly of the DJ4 electric locomotive.

Xie Zhenhua is really in the assembly workshop.

He first watched the assembly progress of the first DJ4 electric locomotive. After so many months of assembly, this locomotive has gradually entered the final stage, and several major systems have been installed on the locomotive, such as the motor traction system, Control system, variable pressure variable flow system and so on.

Xie Zhenhua boarded the car himself, looked at it with satisfaction, and knew that there would be no problem getting off the car in about two or three months.

Then, he looked at the second DJ4 electric locomotive on the assembly platform next to it. This locomotive entered the locomotive a little later, and there was still a relatively long time before it finally got off the locomotive.

The assembly of the traction motor system is in progress today, which is a motor traction system developed and manufactured by Jiuzhou Industrial Co., Ltd.

"Everyone, be careful and slow down."

Seeing that the assembly workers were hoisting a traction motor onto the locomotive, ready to assemble the motor, Xie Zhenhua stood beside him and exhorted loudly.

A supervisor technician in charge of technical guidance said: "Mr. Xie, don't worry, we won't make any mistakes."

Xie Zhenhua looked at everyone's traction motor system assembly, and was about to go back to his office when his cell phone rang, and it was Tang Fei calling.

"Mr. Xie, I came to your office and brought you some good things. Are you interested in coming over to take a look?"

Xie Zhenhua suddenly became interested, and immediately said loudly: "Okay, I'm in the assembly workshop, and I'll be here soon."

Tang Fei waited for a few minutes, then Xie Zhenhua came back, and said loudly as soon as he entered the door: "Tang Fei, what good things did you bring me?"

Tang Fei smiled, took out the things he brought over, put them on Xie Zhenhua's office and said, "Take a look, what is this!"

Xie Zhenhua started to open the package enthusiastically. It was packed in a carton. When he opened the carton, there were foam and bubble film inside, which protected and packaged the contents very well.

Finally, Xie Zhenhua took out the contents and placed them on his desk. At this moment, Xie Zhenhua's heart beat faster invisibly, because he had already seen what it was.

He has seen IGBTs. The Red Star Factory once purchased a batch of imported IGBTs, and some of them have been installed on the two DJ4 electric locomotives that are currently undergoing final assembly.

The IGBT in front of me is a little different from the IGBT that Xie Zhenhua often sees. It seems to be more high-end and more advanced.

This is the fifth generation of IGBT!

Xie Zhenhua shouted excitedly: "This is the IGBT you produced, or a high-power IGBT, which is exactly what we need to use on our DJ4 electric locomotive."

"Yes!" Tang Fei said: "This is the first batch of high-power IGBTs we produced, and there is an instruction manual for this IGBT in the box."

Xie Zhenhua found the instruction manual, looked at it quickly, and after reading it, he gave a thumbs up, "Tang Fei, as expected of the fifth-generation high-power IGBT, the performance is really so good."

Tang Fei said: "In addition to this high-power IGBT, we will also produce several other types of high-power IGBTs. We will produce all the IGBTs needed for the DJ4 electric locomotive in the near future."

"Okay, that's great." Xie Zhenhua almost applauded happily.

After chatting with Tang Fei and learning about the production of IGBTs, he took the IGBT and said excitedly, "Let's go, let's go and announce the good news to Mr. Chang. He should be in the office."

Xie Zhenhua took the IBGT and strode ahead, and the two entered Chang Jinlin's office one after the other.

Chang Jinlin saw what Xie Zhenhua was holding in his hand at a glance, stood up all of a sudden, and said in an uncertain tone: "Old Xie, what is this, is it an IGBT?"

Xie Zhenhua nodded and said: "Yes, it is a high-power IGBT manufactured by Tang Fei and the others, and it is the fifth-generation IGBT. There is also an instruction manual here."

Chang Jinlin read the manual first, and after reading it, he looked at the real high-power IGBT with great interest. When he learned that Jiuzhou Industrial Co., Ltd. will produce several other high-power IGBTs in the near future , Chang Jinlin was excited.

In this way, all the IGBTs required by the DJ4 electric locomotive are available, and Chang Jinlin immediately feels relaxed.

After asking Tang Fei about the IGBT, Chang Jinlin said loudly: "I want to book a plane ticket, I want to go to the capital, and tell the leaders above that we have successfully produced the first high-power IGBT in China."

Xie Zhenhua agreed: "This is really worth a trip to the capital, Mr. Chang. Such a big happy event should also make the leaders above happy."

Tang Fei said that he has no opinion. The first batch of high-power IGBTs produced by him is destined to drop a blockbuster in the domestic rail transit industry, so it's okay to let the upper management know.

A few days later, the first batch of high-power IGBTs manufactured by Jiuzhou Industrial Co., Ltd. was successfully sent to Hongxing Factory.

Chen Guihong, the head of the procurement center, received the batch of IGBTs in person, signed the delivery receipt, and even saw the physical objects of the batch of IGBTs in person.

Yang Jun felt like he was in a dream, after quietly pinching himself, Yang Jun still couldn't believe it.

"Mr. Chen, this is really an IGBT, and it is exactly the IGBT that we need to use on our DJ4 electric locomotive. It's so exciting!"

After speaking, he picked up an IGBT in his hand, looking like he couldn't put it down.

The first batch of high-power IGBTs was sent to Hongxing Factory, all of which were qualified and there was no defective product.This incident also caused quite a stir in the entire Red Star Factory.

Some middle and high-level executives of Red Star Factory are talking about this matter, and their words are full of praise. Everyone knows that imported IGBTs that are stuck are no longer a problem, and they will no longer be stuck.

This is a quiet small building, which is the office of Siemens' staff in the Red Star Factory. In one of the offices, Cross is listening to his subordinate Joseph's report.

After listening, Cross asked, "Is this true?"

Joseph said with great certainty: "This matter is absolutely true. It has spread throughout the Red Star Factory. Jiuzhou Industrial Co., Ltd. has indeed successfully manufactured the first batch of IGBTs, and the things have been sent to the Red Star Factory. into the warehouse of the Red Star Factory."

This is really the case!

Cross pondered, he had also heard some, and now after listening to Joseph's report, he is more sure that this matter is absolutely true.

Now Siemens and Hongxing Factory are in a cooperative relationship, and Siemens will guide Hongxing Factory to manufacture DJ4 electric locomotives.

It’s just that to keep the technology secret, many core components are shipped from overseas, and the Red Star Factory just installs them on the electric locomotive.

High-power IGBTs are also the core and important parts of IGBTs. Siemens has its own stable procurement channels and can easily buy these things from the international market.

In their view, Red Star Factory should be able to buy these things relatively easily, so in the original agreement, it was stipulated that these IGBTs should be purchased by Red Star Factory itself, and Siemens only provided the model and quantity list of these IGBTs.

Unexpectedly, Red Star Factory had many difficulties in purchasing IGBTs. Cross saw all this and thought in his heart that Chang Jinlin would come to him in a short time, begging himself to help Red Star Factory purchase these things.

Chang Jinlin did not come over, but there was amazing news that Jiuzhou Industrial Co., Ltd. successfully manufactured the first batch of high-power IGBTs, and the things have now entered the warehouse of Red Star Factory.

Cross looked solemn, with his hands behind his back, and his brows were slightly wrinkled, walking up and down in the center of his own office.
