Chapter 7, the motherboard cannot be repaired

In this era, the city that girls yearn for the most is not Yangcheng, Shenzhen, or even Suzhou and Hangzhou, but rather the capital of the motherland—Yanjing

I have continuously examined several motherboards, all exhibiting the same issue: a sudden surge of massive current through the motherboard has caused numerous capacitors to be damaged, and some components have instantaneously reached high temperatures, directly melting certain positions of the motherboard's components

Su Qiao's family is well-off; in addition to having a dedicated English tutor, he frequently participates in English summer camps. English is indeed his strongest subject

Last month, the 1999 Olympic Mathematics Winter Camp was held at Yanjing University. Su Qiao's family went to great lengths and spent a considerable amount of money to ensure his participation. Su Qiao also took a week off from school and employed certain strategies to win the second prize, all of which were advantages offered by Yanjing University.

On the contrary, before the English exam, Su Qiao subtly expressed her disdain for Chen Xiao during a conversation with Shen Wei.

He no longer spoke and focused on eating.

Su Qiao bought two bottles of Sunrise Iced Black Tea, handed one to Shen Wei, and said, "Shen Wei, which university are you planning to apply to?"

Although Chen Xiao's integrated circuit diagram is large in size, its principles are simple, making it easy to maintain

However, this matter was originally conducted behind closed doors, and even if Su Qiao is excited and agitated, she cannot speak out

Upon hearing Shen Wei's words, Su Qiao's eyes lit up as she said: "Yanjing University and Shuimu University each have a few designated spots in Jiangyang Province every year. The requirements include a recommendation from the school and a comprehensive assessment by the institution. Having competition experience would be even better. It seems that both Yanjing University and Shuimu University will come to our school for recruitment this time. With your outstanding grades, the school might just recommend you!"

While she said that, Shen Wei still harbored some small expectations in her heart

Chen Xiao is not a child and can understand the last dignity that Chen Qiang, as a father, holds in front of his child

In the summer of 1999, due to the rise of the VCD, DVD industries, and the CNC machine tool industry, there were already many integrated circuit foundries. However, their level still showed a significant gap compared to overseas counterparts

There is not much to say about the comprehensive science; it is Chen Xiao's strong suit

Chen Qiang poured the wine on the table into his stomach, "But this matter is already beyond your capabilities, https://m.hetushu.com. CNC machine tools are high-tech products, and they are imported from Germany. Even your teachers at school might not know how to operate them. Do you?"

Jiang Wei and Deng Chao continued to request Chen Xiao to submit the answers, and Chen Xiao was certainly willing to do so

In the morning, there is comprehensive science, and in the afternoon, there is English

Chen Xiao discovered that most of the motherboard was burned. Repairing it on the original motherboard would be extremely difficult

Chen Xiao is currently unable to explain much to the two individuals, and can only let them worry for a few days. Once the factory here processes the mainboard, the matter will be resolved.

"Chen Xiao, you mustn't be so stubborn!" Chen Qiang felt quite distressed, thinking that he was truly a pathetic father: "I know you want to help bear some responsibilities for the family, and you don't want me to..."

Chen Qiang said: "You are about to take the college entrance examination, so you don't need to worry about this matter; I know how to handle it"

You asked these factories to design an integrated circuit, which is quite challenging. However, for some simpler integrated circuits, they can still manage to replicate them successfully.

Su Qiao felt quite displeased when her conversation with Shen Wei was interrupted. Little did she know that Shen Wei, looking at the bottle of mineral water handed over by Chen Xiao, hesitated for a moment, put down the Xuri Sheng Binghuo tea, and accepted the Nongfu Spring from Chen Xiao

This batch of machines is from DMG Germany, produced in 1995. The size of the motherboard is significantly larger compared to later generations, and the machine tool motherboard is matched with specialized chips.

He took out the mainboard of the CNC machine tool and studied it in detail

The motherboard cannot be repaired, but it can be reproduced

Chen Xiao should simplify the circuit as much as possible; having a slightly larger number of circuits is not a concern. This way, the factories in Jiangcheng or Jiangzhou should be able to proceed with production

Having finished all of this, it is already one o'clock in the deep night

Watching Chen Xiao's departing figure, Su Qiao couldn't help but sarcastically remark: "There is an English exam in the afternoon; some people should be careful not to fail again"

Shen Wei took the Rising Sun iced black tea, thanked him, and said: "I haven't decided yet, but I might go to Yanjing."

Shen Wei hesitated for a moment, clearly unaware of such a matter, and said: "It shouldn't be me, right..."

In other words, whether or not the machine tool has a grounding wire should be questioned

Chen Xiao took out the notebook and began designing the mainboard of the machine tool

It is absolutely impossible to replicate the signal mainboard of Demag according to the craftsmanship of Xia Country on the current m.hetushu.com.

The next day is the final day of the first diagnostic examination

Therefore, Shen Wei is currently unaware of what kind of university she will be attending

Chen Xiao is quite perceptive. Upon hearing Su Qiao say this, he probably already knew the outcome. He handed Shen Wei a bottle of slightly sweet farmer's spring water with a pointed nozzle, saying, "The Xuri Sheng iced black tea contains aspartame and acesulfame, both of which are artificial sweeteners. It is better to drink less of it; mineral water is healthier."

This type of specialized chip motherboard will be accelerated to obsolescence in the coming years. Subsequently, after the CNC machine tools in Xiaguo adopt general-purpose chips, they have embarked on a path from imitation to innovation alongside the development of the national integrated circuit industry

However, Chen Xiao could completely modify the circuit, enlarging the motherboard, simplifying the design of the intricate circuits while increasing their quantity, as long as it ensures that the machine tool can operate automatically

After dinner, Chen Xiao returned to the room

The college entrance examination system in 1999 involved first taking the exam, then estimating one's own score, followed by filling out the application preferences. After the application preferences were submitted, the scores were released.

At this point, Su Qiao was on the verge of exploding with anger

In principle, the machine tool operates on a three-phase 380V voltage, and the control transformer neutral line needs to be grounded. However, Chen Xiao went to the factory today and found that the wiring was in complete disarray.

Chen Qiang, feeling troubled in his heart, continued to drink in silence

Shen Wei did not actually say that her dream university is Yanjing University

From simple to complex, Chen Xiao designed a total of three blueprints. If production is to be carried out based on the blueprint that is the simplest yet has the most circuits, then more than ten CNC machines will need to have a "big belly" patched underneath them, as the original motherboard position of the machines will certainly not be sufficient.

Su Qiao's father, Su Desheng, also stated that there is no issue with attending Yanjing University

In fact, Su Qiao wanted to say that if there are no unexpected circumstances, the point of admission recommended by the school this time should be herself

The lights in Chen Qiang and Lin Hui's room are still on, and the two of them will definitely not be able to sleep tonight

Chen Qiang was determined to take action; at worst, he would go and make a scene, report it, or petition. He did not believe that there was no justice left in this world

Alas! It is truly difficult not to show off

To gain admission to a university of your choice, it is not only essential to perform well in examinations, but also to fill out your application preferences appropriately, and ultimately, a significant element of luck is required

English was difficult for Chen Xiao in the past, but it has become much easier for Chen Xiao now
