God-level industrial master

Chapter 192

To make IGBT, in addition to the technology research and development team, it also needs funds and related manufacturing equipment.

For the time being, Tang Fei already has the first two items. He has set up a research and development team, and the funds on the company's books are temporarily sufficient. What is lacking is related manufacturing equipment.

It is not enough to have a lithography machine, but also an IGBT assembly line and a series of related equipment.The lithography machine is only the core equipment, which is mainly used to make chips and large-scale integrated circuits. What is really needed to make IGBTs is an assembly line to assemble chips, integrated circuits, and various accessories to form an IGBT module.

Since he wanted to do IGBT, Tang Fei listed his plan.

准备用2年左右时间，打造一个具备年产50万片8英寸IGBT芯片生产规模、年产100万只以上大功率IGBT封装及测试能力的产业化基地，产品电压等级从600伏到6500伏全覆盖。

Tang Fei will be the first company in China to master the complete industrial chain of IGBT chips from design-chip manufacturing-module packaging-system application.

The lithography machine has its own, and it is still a very advanced lithography machine. At present, there is a lack of an IGBT assembly line.

Tang Fei also knows what the IGBT production and assembly line looks like.After thinking for a long time, I said in my heart, if there is really no way, then design an assembly line by myself.

In addition to the assembly line of IGBT modules, other related production equipment is needed, which Tang Fei does not have for the time being.

At present, it is very difficult, even almost impossible, to purchase IGBT process equipment in China.In the production and manufacturing process of IGBT, each production process is equipped with special equipment.

Some of them are not available in China, or the technical level is not up to it.For example, the German vacuum welding machine can control the void rate of chip welding to less than 1%, while the void rate of domestic equipment is as high as 20% to 50%.Foreign equipment may not necessarily be sold to China, such as sheet processing equipment.

Another example: the surface blasting equipment produced in Japan is not allowed to be exported by the Japanese government.Good imported equipment is very expensive, and cheap equipment is not applicable.

In addition, automated test equipment is essential but expensive.If manual testing is used instead, human factors will be added, and the test data will have large errors. The IGBT production process is very demanding on the environment.Requires high-standard air purification system, world-class high-purity water treatment system.

Thinking about this, Tang Fei felt a little dizzy.

I even thought in my heart, am I being too reckless? IGBT manufacturing is indeed too difficult. Even if I design the first IBGT with the technical knowledge in my mind, it is estimated that it will be very difficult to manufacture.

Unless you have relevant and supporting production equipment.

Standing in front of the window, looking at the two large factories in the distance that were basically completed and ready to be used for IGBT production and manufacturing, Tang Fei remained motionless and frowned.

After a long, long time, Tang Fei sighed and comforted himself, taking every step counts, there must be a way for the car to reach the mountain, maybe it will be bright.

Well, first design the first 6500V IGBT and complete the task of the system first. Two months is really urgent.

Fortunately, my brother has a full head of technical knowledge and built the framework of the design. Otherwise, it would be almost impossible to complete such a difficult task within two months.

After setting the goal and designing the first IGBT first, Tang Fei's dull mood was much relieved.

Sun Xu and Tang Zhonghua are also very capable, leading several professional and technical personnel, everyone works hard together, and sometimes even work overtime until very late.

The progress of the design is also very good, basically within Tang Fei's expectations. Sometimes, Tang Fei works with everyone to design it himself.

Days pass by.

The batch of IGBTs purchased by Hongxing Factory arrived, which did not affect the assembly of the first DJ4 electric locomotive.With IGBT, the DJ4 traction motor system and control cabinet of Jiuzhou Industrial Co., Ltd. were successfully trial-produced.

Hongxing Factory is in the process of assembling the first DJ4 electric locomotive, and Jiuzhou Industry is also developing rapidly. With the guarantee of sufficient funds, the office building changes almost every day, and the height is being raised layer by layer.

During this time, an interesting thing happened.

Tang Fei received a package from Donghai City. After seeing that the signer was Britt, Tang Fei was still a little curious when he received the package.

What's in it?

He hurriedly opened it, and there were small paper boxes inside. Tang Fei was overjoyed when he saw the package. He guessed what it was, and quickly opened one of them.

That's right, it's really a USB flash drive, a USB flash drive with a storage capacity of 2G.From our current point of view, the storage capacity of 2G seems a little small, but when everyone generally uses 1.44M floppy disks, the storage capacity of 2G is already very large.

Such a USB flash drive is almost worth fifteen hundred [-]-inch floppy disks.Tang Fei became excited all of a sudden, picked up the USB flash drive and inserted it into his computer, and stored some files in the USB flash drive.

The reading and writing speed is fast, and there is no mechanical clicking sound like a floppy disk. Well, this thing is really good.With its advent, the currently widely used [-]-inch floppy disk will be phased out soon.

This Britt is really a caring person, and actually sent me ten USB flash drives.Tang Fei thought in his heart, um, keep a few for himself, and give the others away.

So, not long after, Wang Hailong, Zhao Ke and others all had such a USB flash drive, and even Li Xueyan had one, and it was a pink USB flash drive.

Tang Fei specially picked out the USB flash drives in many colors, knowing that girls like pink, and sure enough, Li Xueyan was very happy to receive this gift.

When I was in the office, Sister Zhang had an electronic file to copy to Li Xueyan, but the file was several megabytes, and it was obvious that a [-]-inch floppy disk could not fit in it. Sister Zhang was worried.

Li Xueyan took out her USB flash drive, plugged it into Sister Zhang's computer, and copied the file easily, leaving Sister Zhang stunned.

After reacting, Sister Zhang seemed to have discovered a new continent, and hurriedly chased Li Xueyan curiously to ask what it was.

Li Xueyan took out her USB flash drive and happily introduced it to Sister Zhang. Immediately, all the colleagues in the office knew that Li Xueyan had this strange thing.

Some colleagues even asked where they bought it, and they also wanted to buy one.However, this kind of thing should not exist in China for the time being.

This is just a small episode.

In the twinkling of an eye, it was November, and the first DJ4 electric locomotive in Hongxing Factory has been in the car for more than two months. The assembly is progressing well, and several major systems are being assembled, such as the traction motor system on the locomotive, the control system, Variable pressure variable flow system and so on.

Xie Zhenhua was very busy, leading his technicians to guide the workers to assemble together with those from Siemens, and also trying to absorb and digest the technology on the DJ4 electric locomotive, hoping to lay the foundation for future independent research and development.

He didn't have time to pay too much attention to Jiuzhou Industrial Co., Ltd., and even in his impression, it seemed that he hadn't seen Tang Fei for a long time.

Sometimes, Xie Zhenhua also wondered what happened to the DJ4 traction motor system of Jiuzhou Industrial Co., Ltd., and what happened to their control cabinet.

Tang Fei seems to be working on an IGBT. He hasn't seen anyone else for so long. Is he really working on an IGBT? Thinking about it, Xie Zhenhua would shake his head. He knows that it is too difficult to make an IGBT. Give up the plan to do IGBT.

During this period of time, Tang Fei was really immersed in the research and development of his first IGBT. Two months will pass in a blink of an eye.

The design work finally came to an end. Sun Xu and Tang Zhonghua personally delivered the final design materials to Tang Fei's desk.

The chief designer of this 6500V IBGT should be Tang Fei, and some important design technical materials will also be handed over to Tang Fei for final review.

Picking up the pen, Tang Fei carefully reviewed the technical documents. Sun Xu and Tang Zhonghua retreated quietly and closed the office door gently.

After more than an hour, Tang Fei finally reviewed this part of the technical information, and found nothing wrong with it. Sun Xu and Tang Zhonghua really had two brushes, and they fully implemented their original design intentions.

This is a veritable fifth-generation IGBT, and it is still at the 6500V level.Generally speaking, the higher the voltage level, the greater the technical difficulty.

After the review, Tang Fei picked up a pen and signed his name, and the design and development work of this IGBT basically came to an end.

In other words, the design is basically complete.The production and manufacturing process data can be compiled. If there are supporting production and manufacturing equipment, then the production and manufacturing can be carried out.

It's just that these production equipment are missing now.

The moment Tang Fei finished signing his name, he let out a long sigh of relief. At the same time, a "ding" sounded in his mind, followed by a system voice.

"Congratulations to the host, you have completed the task, please pay attention to check the reward."

Then there was the sound of gold coins arriving in the account. After completing this task, a total of 1600 gold coins will be rewarded, in addition to a mysterious gift bag.

It seems that the system has fully approved Tang Fei's design, otherwise, the task would not have been completed the moment Tang Fei finished signing.

Haha, a total of 1700 gold coins, you can summon another technical talent.The current system is the third level. There are two summoning quotas at the first level, four summoning quotas at the second level, and eight summoning quotas at the third level.

Seven have been used up before, and there is still one summoning quota.

What Tang Fei wanted to do the most was not to summon an elite subordinate, but he couldn't wait to see what was in the mysterious gift bag!
So, Tang Fei immediately checked the mysterious gift bag. After seeing the contents clearly, Tang Fei yelled "Ah". At this moment, Tang Fei completely lost his composure!

Today is the third update, and the first update is here!
