Guo Yonghe did not find anything strange about the situation introduced by Hu Changzheng.

In the 1980s and 1990s, those foreign high-tech companies always treated Chinese enterprises in this way, and did not respect them as real customers at all.

One famous example is that China Second Heavy Machinery Group Co., Ltd. located in Bashu Province imported a set of large-scale equipment from Germany. After installing it, it was discovered that a large crack appeared in the casting of a frame.

This crack is so huge that after the entire crack is cleared, a large adult man can lie inside without being crowded at all.

The leaders of Huaxia Erzhong were confused on the spot. This involves the entire production line and has a heavy responsibility.

The imminent Erzhong called urgently and asked the German manufacturer for support. The German manufacturer delayed for several months and finally sent a team of experts to China Erzhong to repair it.

The repair plan they proposed did not say that we would redo a frame for you, but instead used surfacing welding and argon arc welding to smooth out the large crack.

The German expert team welded for three months and used 20 tons of welding rods to finally smooth out the crack.

The German manufacturer then sent a professional team with ultra-detection and other instruments to conduct flaw detection on the flattened cracks, and finally issued a report requiring China Erzhong to restrict the use of the entire set of equipment. At most, it could only use the original design.

70% of the production capacity. Otherwise, China Erzhong will be responsible for all consequences!

The current treatment of Zhongtian Aluminum Plant by Texas Instruments and Siemens is nothing more than a repeat of China’s double story.

What made Guo Yonghe feel a little embarrassed was that Zhongtian Aluminum Factory requested that it be repaired within three days.

In his previous life, when he was the chief technician of a new energy automobile giant, if there was a printed circuit board of an industrial computer that needed to be repaired within three days, it would not be difficult for him.

Because he is a top master in repairing printed circuit boards and is even a member of the Precision Welding Branch of the International Welding Association. Not only does he have superb precision welding technology, he also set up his own precision welding laboratory to undertake some difficult printing tasks.

Circuit board repair business.

But now, when Guo Yonghe promised to repair a printed circuit board within three days, he really didn't dare to guarantee it.

Repairing printed circuit boards mainly relies on precision welding technology.

Precision welding is actually a fringe science. No matter how advanced the theory is in this field, it is useless. It mainly relies on a lot of practice to accumulate experience.

For Guo Yonghe, his personal precision welding laboratory repaired tens of thousands of printed circuit boards in his last life, creating economic benefits of hundreds of millions. His practical experience is at the top level in the country, otherwise he would not have been selected for the International Welding

The Precision Welding Branch of the association became a member.

But the problem is that no matter how rich the practical experience is, it still needs the support of professional equipment and instruments.

The precision welding laboratory he opened in his previous life was equipped with all kinds of advanced instruments and equipment, but now, he has nothing, not even a simple electric soldering iron.

Although he can rely on his rich practical experience to make some self-made equipment to replace the advanced equipment and instruments in his precision welding laboratory in the previous life, doesn't this also take time?

If the fault of the printed circuit board of the industrial computer in Zhongtian Aluminum Plant is not serious and he only needs to make some simple equipment to complete the repair, then three days will be enough for him.

If the fault of the printed circuit board of the industrial computer in Zhongtian Aluminum Plant is very serious, for example, the printed circuit is partially burned and the insulation is lost, the entire thickness is carbonized, or the integrated block on the printed circuit board is burned, and the separate capacitor element is burned.

If there is a serious failure such as "flying", then it involves cutting off the carbonized part of the substrate, inlaying a new double hydrogen epoxy resin board to replace the damaged substrate, installing a new integrated block, and may also involve separating the capacitor element and the integrated block.

Soft soldering, etc.

Guo Yonghe can make some of the complex maintenance equipment needed for this by spending a little more time. The problem is the burned integrated blocks and components on the printed circuit board. The procurement of these items is not under Guo Yonghe's control.

, In this case, let alone three days, let alone three weeks, Guo Yonghe did not dare to guarantee it.

"Chief Hu,"

Guo Yonghe naturally did not dare to talk nonsense on this issue, "There are various faults in printed circuit boards of industrial computers. It is definitely not difficult to repair minor problems within three days. If a major problem is encountered, the time limit is hard to say."

"So I can't guarantee anything to you now. I can only tell you after I go to the scene and see the actual situation."

What Hu Changzheng and Guo Yonghe said is the truth.

In fact, he came over to ask Guo Yonghe, and he didn't expect that Guo Yonghe would be able to repair it within three days. He mainly had the idea of ​​​​making a fool of himself. If Guo Yonghe could repair it within three days, he would naturally make a lot of money.

, my son will definitely be kept by Zhongtian Aluminum Factory.

Even if Guo Yonghe cannot repair it, his son Hu Dongqiang will not suffer any loss. At least he has shown to the leaders of Zhongtian Aluminum Plant his attitude of actively participating in factory affairs!

"It's okay! Technician Guo, no matter whether it can be repaired within three days or not, I will always remember your friendship!"

Hu Changzheng said: "In the future, whenever you need me for anything, just come to me. If I say no more, just slap me!"

Listening to Hu Changzheng's rude words, Guo Yonghe couldn't help but laugh.

If they hadn't heard it with their own ears, who would have thought that these words would come from the mouth of the head of the equipment department of a large provincial factory?

Soon, they arrived at Zhongtian Aluminum Factory.

Hu Dongqiang was standing at the gate of Zhongtian Aluminum Factory, waiting anxiously. When he saw the jeep from the Heavy Machinery Factory approaching, he immediately rushed to greet it.

"Dongqiang,"

Hu Changzheng pointed at Guo Yonghe and introduced: "This is technician Guo from the internal parts factory. He specially asked for leave to come over to help you repair the printed circuit board. Why don't you thank him quickly!"

"Thank you, Technician Guo!"

Hu Dongqiang looked at Guo Yonghe, who was about the same age as him. Although he was full of suspicion, he obediently thanked Guo Yonghe according to Hu Changzheng's words.

There is no way, who makes him want to stay in Zhongtian Aluminum Factory?

Regardless of whether the young technician Guo is reliable or not, there is no harm in giving it a try.

"Haha, we are all our own people, why are you so polite!"

Guo Yonghe waved his hand to Hu Dongqiang, "Let's go, take us to the scene and see what's going on!"

So Hu Dongqiang said hello to the guard, then jumped on the jeep and took them into the factory, to the equipment department on the first floor of the factory office building, and knocked on the door of Li Weijin, the director of the equipment department office.

"Director Li,"

Hu Dongqiang reported the report respectfully: "My dad invited expert Guo who repaired the printed circuit board."

Li Weijin is a fair and fat middle-aged man who looks like Maitreya Buddha.

He couldn't help but be startled when he saw Guo Yonghe standing next to Hu Changzheng.

Although Hu Dongqiang had already reported to him that Expert Guo was very young, he really didn't expect that Guo Yonghe was so young and seemed to be the same size as Hu Dongqiang who had not yet left school.

"Expert Guo, hello, I didn't expect you to be so young!"

Fortunately, he quickly came to his senses, stretched out his big fat hand, and greeted Guo Yonghe with a smile.

"How about you, Director Li! "

Guo Yonghe shook hands with Li Weijin and replied with a smile: "I just look young. I was actually born in 1969 and will be twenty-three years old soon!"

Li Weijin almost choked at Guo Yonghe's words.

You're not even twenty-three years old, how dare you say you look young?

Are all the young people of this generation so difficult to lead?

He stood firm and extended his hand to Hu Changzheng again, "Chief Hu, please worry about it!"

"Hi, Director Li, you are so polite!"

Hu Changzheng shook his head repeatedly and said: "Expert Guo and I have known each other for a long time, so inviting him here is just a simple task. But Dong Qiang works under you, which gives you a lot to worry about!"

After a few simple greetings, Li Weijin got to the point.

"Expert Guo, the situation is like this..."

Compared with the situation Hu Changzheng introduced to Guo Yonghe in the car, the situation introduced by Li Weijin had more content.

It turns out that the main product of Zhongtian Aluminum Plant is alumina, and the last process in alumina production is the roasting of aluminum hydroxide. When this process of Zhongtian Aluminum Plant was initially put into operation, it used an internationally advanced flash roasting furnace.

The industrial computer used was designed by Germany's Humboldt Wedak Company and produced by Honeywell.

A year ago, Zhongtian Aluminum Plant was preparing to invest in the construction of the second phase of the project. At this time, the model of the flash roasting furnace industrial computer equipment used in the first phase of the project was included in the list of obsolete equipment by Honeywell, and equipment maintenance services were not provided.

Therefore, Zhongtian Aluminum Plant decided to switch to Texas Instruments industrial computers for the flash roasting furnace production line of the first phase of the project, in preparation for the complete elimination of Texas Instruments industrial computers for the second phase of the project.

Unexpectedly, Texas Instruments eventually sold its industrial control department to Siemens of Germany. Zhongtian Aluminum Plant jumped from one big pit into another!

"Director Li, I understand the situation pretty much!"

Guo Yonghe nodded and said: "I'd better ask Director Li to take me to the scene. I have to see the damage to the printed circuit board in person before I can specifically judge whether it can be repaired and how long it will take."

"Okay, okay!"

Li Weijin nodded and led the way, preparing to take Guo Yong and the others to the Equipment Maintenance Department.

As soon as I walked into the corridor, I bumped into several people. The middle-aged man in the lead was wearing a long Pierre Cardin windbreaker, and he looked very impressive.

The middle-aged man caught a glimpse of Li Weijin and Hu Changzheng and his son and Guo Yonghe behind him. He couldn't help but stop and asked Li Weijin: "Old Li, what are you going to do?"

"Director Zhang,"

Li Weijin quickly laughed and said: "Isn't the printed circuit board of the industrial computer in the flash roasting furnace production line broken? The father of Xiao Hu, a college student who interns in our office, happens to know an expert who can repair printed circuit boards, so I asked him to repair it.

Please come here and see if this expert can help us repair the printed circuit board..."
