"3 minutes and 21 seconds! haha...... Brother Jiang, it only took you 3 minutes and 21 seconds to completely replace the CPU of these 20 PCB boards, it's too fast!!"

When Jiang Ning put the last circuit board on the fan to cool down, turned off the air gun, and put down the tweezers, behind him, the little girl Shen Jia suddenly exclaimed, she pointed to the time on the phone with her little finger, and shouted. Pen, fun, pavilion www. biquge。 info

3 minutes and 21 seconds, it's ...... It's so fast, it's super-godly, it's incomparable!

Twenty PCB boards, twenty CPU chips, known as the most difficult CPU chip, were completed by Jiang Ning in just 3 minutes and 20 seconds, I have to say that this is a miracle!

The difficulty of replacing the soldering of the CPU chip can be said to be the part of the circuit board with the highest soldering difficulty coefficient, the time taken by the ordinary maintenance engineer to replace a CPU chip, generally takes more than a minute, 3 minutes and 20 seconds, and it is only enough for the ordinary maintenance engineer to replace 3 CPU chips, however, Jiang Ning has replaced as many as 20 pieces, what kind of efficiency is this?

The shout of the little girl Shen Jia almost frightened Zhang Chenglin, the maintenance supervisor on the other side, to throw away the air gun......

Isn't it just that the paralysis has been replaced? What is it called?

Zhang Chenglin was annoyed in his heart, but he didn't dare to be too distracted, because the temperature of the air gun in his hand was 400 degrees high, which was twice as high as the temperature he usually used for welding.

Although Zhang Chenglin has turned up the temperature a lot, and the speed of replacing the CPU has also accelerated a lot, however, after Jiang Ning completed it, he has also replaced six pieces on his side, and is working on the seventh piece, his speed is much faster than other engineers, but if you compare it with Jiang Ning, it is a piece of, and it is simply a data that has been crushed.

Hmph! What is the fast replacement? The replacement is fast, and when I test it later, there are a lot of problems, and it is also replaced in vain!

Zhang Chenglin gritted his teeth and shouted in his heart.

In fact, in the maintenance room, there are really a lot of people like Zhang Chenglin who think so.

Although, Jiang Ning's previous hand speed was unparalleled, which made everyone marvel, however, repairing the PCB board and replacing the CPU chip does not mean that it can be replaced quickly!

There are hundreds of solder balls under the CPU chip, each solder ball is a pin, if in the process of soldering, there is a solder ball, open circuit or short circuit, then, the entire CPU soldering is all scrapped, which has the highest requirements for the soldering technology of the repairer.

As we all know, speed and quality are a pair of contradictions, if the speed is too fast, it will inevitably lead to a decline in quality, which is an eternal truth.

And Jiang Ning's current situation is not like this? His welding speed is fast, almost comparable to that of an airplane, but at such a speed, how many CPUs can be soldered? Even, some people are thinking, Jiang Ning's 20 PCB boards that have replaced CPUs, it is estimated that none of them are good!

Because it's too fast, it's not good, and this has almost become a consensus among people.

Although Jiang Ning is leading the way in replacing the CPU speed, what is more important is the success rate! No matter how fast you are, there is no success rate, which is the same as 'no matter how many zeros there are, there is no non-zero number pressure field in front, this number is still zero'.

So, after Jiang Ning completed the replacement of the CPU of the 20 PCB boards at 'god speed', only the people in the hardware department cheered and cheered for him, while the people in other departments did not say much, they believed that Zhang Chenglin, the maintenance supervisor, would definitely 'work slowly and carefully'.

Even, the people in the maintenance department didn't have much worry on their faces, and they still firmly believed that their supervisor Zhang Chenglin would definitely be able to defeat Jiang Ning, win the other party's salary, and invite them to dinner at night.

In the midst of everyone's expectation, anxiety, ridicule, or indifferent waiting, finally, after more than seven minutes, Zhang Chenglin's side also replaced 20 CPUs.

Coupled with the previous three minutes, Zhang Chenglin's total time is enough for more than ten minutes, of course, someone also timed him next to him.

Now, if Zhang Chenglin wants to win, he can only hope for the success rate!

"Hoo ......"

After Zhang Chenglin completed the replacement of the last CPU, he couldn't help but sigh, such a high-intensity work, he was the first time in all these years, and what was even more speechless was that even if he played super long now, in terms of speed, he was still killed by Jiang Ning.

Thinking of this, Zhang Chenglin couldn't help but look at Jiang Ning's side, the 20 PCB boards that had been placed there for a while, "Deputy Director Jiang, high! It's really high! I didn't expect your welding speed to be so fast, Zhang Chenglin admired, hmm...... Now, let's make a rule for judging wins and losses, shall we?"

"Didn't the charter be said before? Whoever changes quickly and has a high success rate will win?"

Jiang Ning was a little confused.

I'll go, brother, I said that before, didn't I think that I can crush you in terms of speed and success rate, so there is no need to be so clear, and now, I have a high success rate, but I am left behind by you in speed, so if you don't have a charter, how can you judge whether you win or lose?

"Ahem...... Deputy Director Jiang, that's right, the criteria I said earlier to judge the winner are a bit general, well, for example, now you have 16 CPU soldering successfully, and I have 20 CPU soldering successfully, although my success rate is higher than yours, but the time I took is longer than yours, so I can't tell who is the winner, right?"

"So, in order to avoid this from happening, we should further refine this rule, well, Deputy Director Jiang, do you think this will work, if there is a piece of CPU soldering is bad, then, who should be given an additional minute of 'penalty time', so that in the end, we can all calculate the short time, and the short time will win, what do you think?"

In fact, when Zhang Chenglin said 'punishment time', he also has his own little Jiujiu, because, whether it is his welding speed or Jiang Ning's welding speed, the time required to replace a CPU is far lower than this time, his welding speed is about 30 seconds to replace a CPU, and Jiang Ning's only needs 10 seconds!
