When the visitor saw that Tang Fei had a guest, he immediately gave an apologetic look, immediately retreated, and closed the door gently.

At first glance, it may seem unfamiliar. But soon Tang Fei knew who it was, and he was happy in his heart, and it was okay to see the other party withdraw, so he didn't say anything. Anyway, everyone has already arrived, and there is no hurry for this time.

Of course, Xie Zhenhua didn't know this middle-aged woman, he said: "Mr. Tang, you have a guest coming, delaying you." ”

Tang Fei waved his hand and said, "No, no, you just asked when the DJ4 control system of the second car will be trial-produced, right?"

"Yes, yes, that's it. ”

This is Xie Zhenhua is very concerned, the first car control system trial production, definitely not used to deliver to the Red Star Factory, because the first control system has gone through many tests, including a variety of harsh environment tests, and the final destructive test.

After so many tests, no matter how good the quality of this control system is, it cannot be installed and used, and it must wait for the second or even the third.

With such an excellent and excellent control system, Xie Zhenhua wanted to get it as soon as possible and install it on his electric locomotive as soon as possible.

Tang Fei thought for a moment and said: "Well, it will probably take about a month, and in the next month, we will improve the design data and process data according to the problems exposed in the trial production process of the first vehicle control system." ”

"It is estimated that it will take about a month, after these are all perfected, we will start the control of the second car control system, and strive to use about two months to trial produce the control system of the second car, and in the second half of this year, we strive to enter the small batch production of the DJ4 control system, and enter the official mass production next year. ”

The trial production of the control system of the first car took more than four months, because it was necessary to cross the river by feeling the stones, to accumulate experience, and to rectify problems encountered in the encounter.

With the trial production experience and foundation of the control system of the first car, the second car will be much faster, and the production and manufacturing cycle of the third will be shortened, and when it enters the small batch manufacturing, at that time, the technology is relatively stable and mature, and the manufacturing cycle of each control system will be greatly shortened.

Xie Zhenhua is engaged in technology and knows all this.

He just didn't think about it, Tang Fei and they only needed a month, and then they could start the trial production of the control system of the second car, he thought it would take at least two or three months.

He believes that after the trial production of the control system of the first car is completed, there must be many problems that need to be rectified, and the design data and process data need to be greatly improved, at least two or three months.

"Mr. Tang, you only need a month!"

Xie Zhenhua's tone was full of surprise, especially when Tang Fei said that he would enter small-batch production in the second half of this year.

In this way, the DJ4 electric locomotive produced and manufactured by the Red Star Plant in small batches can be equipped with a completely localized control system, because the small batch production and manufacturing of the DJ4 electric locomotive by the Red Star Plant is also around the second half of this year.

After talking to Tang Fei, Xie Zhenhua seemed to have taken a reassuring pill, and he knew that Tang Fei still had guests, and he didn't want to delay Tang Fei's time.

He got up and said goodbye: "Mr. Tang, then I'll go back first, and I want to make a detailed report to Mr. Chang about what I have learned." ”

Tang Fei got up to see him off, sent Xie Zhenhua to the door of the office, and then returned to his boss chair and sat down.

Not long after, there was another knock at the door.

The capable middle-aged woman knocked on the door just now and said respectfully, "Hello boss, Hao Hongxia reports to you." ”

Tang Fei's guess is completely correct, this is the technical expert in the field of microelectronics and chips he called, Hao Hongxia, a researcher at a famous microelectronics research institute in China.

"Expert Hao, you came so fast, among the four of you, you were the first to arrive. ”

Hao Hongxia said: "Boss, I am in China, I will resign immediately, and I will come here by plane, I hope to devote myself to work as soon as possible and develop our first mobile phone chip as soon as possible." ”

It's a good thing to be motivated.

Tang Fei felt in his heart that he was worthy of being an expert summoned by himself, with a strong sense of professionalism and loyalty to himself, and as soon as he was called, he immediately came to report.

After chatting with Hao Hongxia and understanding some basic information about her, Tang Fei called Wang Hailong over, and he arranged for Hao Hongxia to settle down temporarily, and then go to Shenhai City together after the other three arrived.

The first car's DJ4 control system was successfully trial-produced, and not long after, the DJ4 control system designed and developed for Nie Qingshan's factory also fully completed the trial production preparations and began trial production.

Because of the technical basis for the successful trial production of the first DJ4 control system for the Red Star Factory, the preparation for the trial production of this DJ4 control system was much smoother and much faster.

Hearing that the trial production was completed and the trial production was about to begin, Nie Qingshang was very happy, although others did not come, they specially called over and expressed their gratitude to Tang Fei.

Nie Qingshan's words were full of gratitude.

Jiuzhou Industrial Co., Ltd. has done them a great favor, after completing the trial production preparations, will usher in the formal trial production, and their factory will be able to use the domestic electric locomotive control system in the future.

They are also promoting the work of increasing the localization rate, and the goal is also to achieve the localization rate of the DJ4 electric locomotive to more than 80%, with the localization of the electric locomotive control system, they have no problem to achieve this goal.

As Hao Hongxia was the first to report, the other three people appeared one after another, reporting to Tang Fei, and in just a few days, all four of them arrived.

There are a total of three technical experts in the field of chips, and one expert in enterprise management, with rich advanced management experience in large enterprises.

After the people arrived, Yang Chenglin and Wang Xingkui also rushed back from Shenhai City.

As soon as the two of them returned to Jiuzhou Industrial Co., Ltd., the first thing they did was to stride into Tang Fei's office and report to Tang Fei.

Seeing that the two of them were back, Tang Fei was very happy.

"It's all hard work, please sit down, if you want tea, do it yourself. ”

Yang Chenglin was familiar with the situation in Tang Fei's office, and he was familiar with it, so he made three cups of hot tea by himself, Tang Fei, himself and Wang Xingkui, one cup each.

After brewing the tea, he sat down on the sofa again, and first introduced the latest situation of the chip base in Shenhai City to Tang Fei.

After listening to the report, Tang Fei felt very relieved that the first phase of the project of his chip base began to be built last year, and it took about half a year to basically complete and be put into use. Even the chip design and R&D center with the largest amount of engineering volume and the largest construction area is about to be completed.

Wang Xingkui also took the initiative to report his work, he has set up a technical team of more than 100 people in accordance with Tang Fei's instructions, including several doctoral students, more than a dozen technical personnel with master's degrees, and the rest of the lowest academic qualifications are key universities, undergraduate students in related majors.

Yes, yes, the technical team has been basically formed.

Wang Xingkui also reported on the selection and procurement of chip production and manufacturing equipment, as well as related scientific research and test equipment.

Some of the equipment is about to arrive, and some of it has already been loaded abroad and is being shipped to sea. Speaking of these equipment purchases, especially the procurement of imported equipment, there is a small story in the middle.

Chip research and development, production and manufacturing, need to use several relatively high-end imported equipment, Wang Xingkui contacted a foreign manufacturer, but people do not sell.

After he reported the situation to Tang Fei, Tang Fei only needed a phone call to get it, and Demark Machine Tool Group acted as an intermediary.

At the beginning, there was an agreement that Demark Group purchased IGBT products and servo motor products from Jiuzhou Industrial Co., Ltd., and when Jiuzhou Industrial Co., Ltd. encountered difficulties in importing equipment, Demark Group had the obligation to help.

Demak Group also did what it said, and after their senior management received Tang Fei's call, they immediately took action and contacted the chip equipment manufacturer.

Maybe it's all the same equipment manufacturers, maybe it's the Demark Group that states the pros and cons, maybe it's the IGBT products and servo motor products of Jiuzhou Industrial Co., Ltd. that play a role.

The chip equipment factory loosened, and then changed its strategy, fully agreeing to sell the equipment to Jiuzhou Industrial Co., Ltd.

In this way, all the equipment required for the first phase of the project, including scientific research and test equipment, was completed, except for the most critical lithography machine.

This thing is not simple, it is not easy to buy it, fortunately, Tang Fei did not propose the need to import lithography machines at all.

Wang Xingkui also thought that when the chip was manufactured, the large lithography machine in the Qingjiang factory area might be used.

Wang Xingkui said: "Boss, all the equipment is done, and it will arrive one after another, and then it can be installed and debugged, but there is a lack of wafer production and manufacturing equipment, and there is also a lack of key lithography machines." ”

Tang Fei smiled and said lightly: "These equipment are already in place, especially the lithography machine, we already have a second large-scale lithography machine with advanced performance." ”

"That's great. Hearing this, Wang Xingkui was relieved for a while, and reported some of his other aspects of work.

After listening to the work report of the two, Tang Fei said: "I called you all the way back from Deep Sea City, do you know what is going on?"

The two shook their heads slightly, they really didn't know what was going on for the time being, anyway, it was definitely not to listen to their work report in person.

If you want to know the situation of the chip base in Shenhai City, Tang Fei can completely use the phone, besides, Yang Chenglin will take the initiative to call to report the latest progress of the chip base every once in a while, and Tang Fei knows more about the situation of the chip base.

There was no need to go through any trouble to get the two of them back from Deep Sea City.

The two looked at Tang Fei and waited for Tang Fei to continue.
