What is the concept of doubling the temperature?

That almost a minute, the board will be 'burned' rhythm, in this way, the board and components, won't they have to be reimbursed? Even if Jiang Ning replaces the CPU, then this PCB board can't be used at all? As I said before, the success rate of PCB maintenance is the most important, no matter how short the time you use, but if you don't repair the board, it won't have the slightest effect!

Sure enough, haha...... Sure enough, this Jiang Ning is still a fancy shelf! I saw him wielding the air gun with his two hands just now, and I thought there were two brushes, but it turned out to be just an empty shelf, and I didn't even know how much to adjust the temperature, and I had to repair the PCB board and replace the CPU?

People from other departments around couldn't help but think of it. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

At this time, not only them, but even Zhang Min and Bi Zhonghua, who stood on Jiang Ning's side, were also a little stunned, for maintenance, Zhang Min, Bi Zhonghua, Cao Jianwei These people are naturally familiar with the road, and they are naturally familiar with the temperature of soldering CPUs, but now, seeing Jiang Ning come up, the temperature is so high, suddenly, they are all a little dumbfounded.

Is this the rhythm of 'making waste boards'?

For a while, everyone couldn't help but be confused by the second monk, and fired the air gun to such a high temperature, not to mention the components, even if it was a synthetic PCB plate, it couldn't withstand this high temperature, and soon, they would all break down at this temperature, so that not only could not repair the PCB board, but on the contrary, the board was completely scrapped?

In the eyes of Zhang Min, Bi Zhonghua, Cao Jianwei, Liu Yunlong, Shen Jia and others, if Jiang Ning followed the method of soldering the PCB board yesterday and came step by step, there should be no problem in defeating Zhang Chenglin, but now he suddenly came up with such a 'stupid move', what is the purpose of this?

Hey, that's not right!

Just now, Zhang Min saw her little boyfriend Jiang Ning adjust the temperature of the air gun so high, and the first reaction in her mind was also the above, but after a few seconds, this thought in her mind immediately stopped, because she saw that after Jiang Ning aimed the muzzle of the air gun at the CPU chip, just a few seconds later, the tip of the tweezers in the other hand quietly touched the CPU chip.

This is......

After a moment of doubt, Zhang Min's beautiful eyes suddenly burst out with a dazzling brilliance, because she had already vaguely guessed Jiang Ning's intentions at this time!

Sure enough, in the next moment, her little boyfriend Jiang Ning was controlling the tweezers and trying to pick up the CPU chip.

After touching it twice and making sure that the solder under the CPU had completely melted, Jiang Ning's fingers moved dexterously, and the tweezers in his hand accurately clamped the edge of the thin chip that was only about a millimeter, and then, Jiang Ning's palm was slightly forced.

Swish!

Suddenly, the CPU chip was taken off the board at once!

Immediately afterwards, Jiang Ning did not pause at all, put down the CPU in question, and instead, with an extremely dexterous clip, he clamped a good piece of CPU next to him on the tweezers, and then quickly put it under the muzzle of the wind gun and heated it up!

Due to the very high temperature of the air gun, so, only one or two seconds later, the solder ball on the CPU was completely melted, and the speed in Jiang Ning's hand was called a gallop, only to see that he smacked, it was a good CPU chip, extremely lightweight, and accurately placed on the soldering position of the PCB board!

Next, Jiang Ning moved the air gun in his hand and continuously heated it to complete the welding of the entire CPU.

Hiss......

The people who saw this scene couldn't help but gasp at this moment, because the few hands that Jiang Ning played just now made them all a little dazzled, too fast!

From blowing off the CPU chip, to putting another good CPU chip on the board, and heating and soldering it with an air gun, the whole process is only a few seconds!!

A few seconds, what can you do in a few seconds? It's just a few blinks of your eyes, however, it is in this fleeting time that Jiang Ning actually completed the picking, replacement, and re-soldering of the CPU chip, I have to say, this is really a scene that makes people look at it and feel a little shocking!

At this time, not only those who had a good relationship with Jiang Ning, but even those who were on the opposite side of the field, other departments, and even the maintenance department, they were deeply impressed by Jiang Ning's hand just now.

Not to mention whether the CPU effect that Jiang Ning soldered out in the end is good or bad, just Jiang Ning's picking, replacing, and soldering steps, among the people present, no one can do it so far!

Sure enough, this little ginger is really ......

Seeing Jiang Ning's actions, at this time, Zhang Min had already determined what he had just thought.

That is, the reason why Jiang Ning turned the temperature of the air gun so high was not because he lacked welding experience and was doing nonsense, but because he had a purpose, and his purpose was...... To speed up the whole welding process!

If you replace the CPU by soldering step by step according to the conventional method, although Jiang Ning has some advantages, it will definitely not be too big, after all, Zhang Chenglin on the other side is not a vegetarian, and his welding speed is also extremely fast, and even, I am afraid it is very close to the limit.

But Jiang Ning is doing the opposite, what he is doing now is to greatly 'expand' this 'limit value'!

The one asked, since it's the limit, how can it be expanded? Just kidding, right?

Actually, this is not the case, the limit value just mentioned is under the 'conventional conditions', so what are the conventional conditions?

The so-called conventional conditions are actually at the temperature of the air gun, at a 'balance point', that is, the temperature that Zhang Chenglin is now using, to replace the CPU step by step.

And now, Jiang Ning has doubled the temperature all at once, and one of the qualitative changes it has brought is ...... The melting speed of the solder is greatly accelerated, so that the time taken to pick the CPU, replace the CPU, and solder the CPU will be greatly reduced, which also greatly expands the 'limit value'!

However, this has a great disadvantage, and its disadvantage is that baking components and PCB boards at such a high temperature will cause irreparable damage to the PCB board and components for a slightly longer time!

However, what Jiang Ning is doing now is that he took advantage of such a 'lost' time to quickly complete the CPU replacement!
