"Jiang Ning, you, you fart! How can the schematic diagram drawn by my Li Jian be wrong? You are simply unbelievable!"

When he heard Jiang Ning say that the problem of this project might be in the schematic, Li Jian, a senior hardware engineer of Feituo Company, suddenly jumped out and pointed at Jiang Ning and scolded angrily. Pen % fun % Pavilion www.biquge.info

On the other side, Shen Jia, who was standing in the crowd, did not tremble, because the PCB diagram of this project was drawn by her, and if something really went wrong, she didn't dare to think about the consequences......

I, my PCB diagram, but Director Zhang and Lao Bi have checked it before, it should be, there shouldn't be any problems, right?

The little girl Shen Jia's heart couldn't help but beat the drum, at this time, she had no time to think about why Zhang Min and Jiang Ning were so close before, if there was really a problem with her PCB drawing, then, in the past few days, everyone has worked overtime without rest, but it's all because of her? This is something that the little girl can't bear.

"Jiajia, it's not decided yet, you don't have to worry too much, even if there is a problem, just change it, this is not a trial production circuit board? ”

Jiang Ning comforted Shen Jia, who was so frightened that his little face turned white, but he didn't take care of Li Jian of Feituo Company.

This, this is determined? It's a little too fast, isn't it? How did Jiang Ning determine it?

At this time, everyone in the laboratory couldn't help but be suspicious, especially Zhang Min, Lao Bi, Cao Jianwei, these people with excellent hardware technology, they were extremely curious about what method Jiang Ning used to solve the problem so quickly, but Jiang Ning was in SH City at that time, and they were not fortunate enough to see it.

Now, there is also a thorny problem in their company, and it coincides with Jiang Ning coming, so these people are staring at Jiang Ning one by one, to see how he solves this problem that they have not solved for several days.

However, he didn't want to, Jiang Ning came here, just asked people to power on the circuit board, and then pressed the power button, only carried out these two simple actions, and then determined the problem.

Moreover, the conclusion Jiang Ning said was very different from what everyone had suspected in the past two days!

Previously, everyone came to the conclusion that the problem of this project may come from the CPU itself, which is caused by the defective rate of this external component, but now Jiang Ning ruled out this possibility as soon as he came up, and said that the reason may come from the schematic diagram or PCB diagram, which makes everyone a little unbelievable.

For the schematic diagram and PCB diagram, in fact, everyone has also checked in the past two days, especially the PCB diagram drawn by Shen Jia, because it was drawn by their own people, so everyone held the attitude of not making mistakes on their own side, and carried out a comprehensive three-dimensional cross inspection of the PCB diagram drawn by Shen Jia, and found that there was no problem.

As for the schematic diagram drawn by Li Jian of Feituo Company, although everyone did not check the PCB diagram as carefully as Shen Jia, several people also checked it several times, and they didn't see anything wrong.

Now that Jiang Ning has come, he has overturned everyone's previous inferences, and there is no doubt that this can't help but make everyone feel a little unbelievable.

"Little brother Jiang Ning, this ...... I've seen that everyone has looked at the schematic and PCB diagram many times, and the results are all fine, right......?

Although Xiao Tiansheng didn't know much about technology, he had been staying with these engineers every day in the past few days, and he had seen what the engineers were doing, and now when he heard that Jiang Ning had denied the conclusions reached by the previous engineers in the past few days, he immediately raised his doubts.

Bi Zhonghua, Cao Jianwei, Zhang Min and others, although they did not speak, but their eyes were obviously full of doubts, thinking that Jiang Ning had made this conclusion so simply, which was a little rash.

On the other side, Tang Haotian snorted even more coldly, and said: "Hmph, Jiang Ning, I think you are just playing tricks, just turn on the power, turn on the machine, it's so simple, just determine the problem of the board, then what do you need those sophisticated instruments for? Why do you need so many professional hardware engineers? You want to be so capable, what to hand over to you, let you take a look?"

Speaking of this, Tang Haotian suddenly turned his head to Xiao Tiansheng and said: "Xiao Dong, see it, he Jiang Ning came to our company to make trouble, we don't have much time, he is purely delaying our time, just through a dog-fart test, he came up with a dog-fart result, it's just a dog-fart, Xiao Dong, such a person, I think it's better to kick him out as soon as possible!"

Tang Haotian's proposal was immediately responded to by Li Jian, and he had already seen Jiang Ning unpleasantly, "Yes, Boss Xiao, Jiang Ning's series of actions just now, let alone solving the problem, his unprofessionalism is not even as good as an intern, at his level, you still expect him to be able to solve the problem? is such a person, it is a waste of everyone's time for you to let him stay here!"

"Guys, is there anyone who has better soldering skills and can fly wires on the CPU? Can you do me a favor?"

Jiang Ning didn't bother to pay attention to Tang Haotian and Li Jian, the two clowns who jumped off the beam, he directly said his requirements, he thought, first prove his conclusions through facts, and then deduce what went wrong.

Flying on the CPU? This is a difficult technical job!

The so-called 'flying wire' is a professional term in the mobile phone solution company, in fact, it is a measure to draw out a wire on the circuit board.

This 'flying wire' measure will generally occur often on the trial production board, because there will generally be such and such problems on the trial production board, because the circuit is fixed, so when adjusting these problems, only the wire can be drawn from the circuit board to be adjusted.

The situation of the flying line is varied, the most difficult of which is naturally this direct flying line from the CPU, the reason is that the CPU pins are dense, there are hundreds of them, and the distance between each pin and the pin is pitifully small, in the process of the flying line, either the tin is not conductive, or the tin is slightly more, it will make the other pins short-circuit!

In addition, the soldering of the CPU, the most complex component with hundreds of dense pins, also requires extremely high soldering technology.

Combining the above two points, the technical difficulty of the action of flying out of the CPU is simply too high, and the average engineer is not competent at all, however, at this time, everyone's eyes can't help but look at Cao Jianwei, because, before he served as a hardware engineer, he was an extremely powerful maintenance engineer, he said that his welding technology is the second, and no one dares to say that he is the first.
