"Lin Gong, you're quite on time!"

Guo Yonghe greeted him with a smile and said to Lin Wenhai: "You only spent fifty-nine minutes in the equipment maintenance department and came out. You must have repaired the printed circuit board?"

"Bah, schadenfreude bullshit!"

Lin Wenhai spat fiercely at Guo Yonghe, "If you have the ability, just go in and fix it for me! I don't believe it at all. Even I can't fix things, but you, a shitty little technician like you, can fix it!"

"hehe!"

Guo Yonghe smiled and shrugged, "There are so many things you don't believe! Since you are not convinced, just wait outside with your dog eyes wide open to see how I can repair the printed circuit board!"

As he spoke, Guo Yonghe turned around and said to Li Weijin behind him: "Director Li, let's go in first to see what's going on?"

"good!"

Li Weijin nodded.

Now that things have come to this point, he definitely has no reason to back down.

Anyway, it turns out that Zhang Jianshe’s nephew was not able to repair the printed circuit board of the industrial computer, so even if the Guo Yonghe he invited couldn’t repair the printed circuit board like Zhang Jianshe’s nephew, there would be nothing to be ashamed of!

"Chief Hu, you and Dong Qiang just wait outside for a moment. I'll go in with Expert Guo to see what's going on."

He told Hu Changzheng something.

Although Hu Changzheng really wanted to watch Guo Yonghe repair the printed circuit board live, he also knew that it was not appropriate for the father and son to follow him under such circumstances, so he pulled Hu Dongqiang to wait in the corridor outside.

"Expert Guo, let's go in!"

Li Weijin took a long breath to calm down his excitement, and this time he led Guo Yonghe into the equipment maintenance department.

In the Equipment Maintenance Department, Zhang Jianshe, Chief Tang of the Equipment Maintenance Department, and several engineers were sitting at the workbench, looking at the large printed circuit plug-in board placed on it, helpless.

"Director Zhang,"

Li Weijin walked up to Zhang Jianshe and asked for instructions: "Since the forest workers can't repair the printed circuit board, why not let the expert Guo I invited over give it a try?"

"Director Li,"

Zhang Jianshe sighed and said: "The maintenance and repair of equipment is originally your responsibility. If you want Expert Guo to try it, can I still stop you?"

As he spoke, he pointed at Guo Yonghe and said to Section Chief Tang: "Old Tang, this is Expert Guo who was specially invited by Director Li to repair printed circuit boards in our factory. Please introduce the situation to him in detail. Let's see.

Let’s see if the expert Guo invited by Director Li can do anything.”

Section Chief Tang looked at Guo Yonghe's overly young face and was filled with doubts.

You know, Zhang Jianshe's nephew is an engineer at Beijing Computer Factory No. 1. Even he is helpless with this large printed circuit board. How can the young expert Guo in front of him be able to repair it?

However, since Zhang Jianshe had confessed, and Expert Guo was specially invited by his immediate boss Li Weijin, Section Chief Tang, even if he didn't believe it, had to cheer up and introduce the fault situation of the printed circuit board.

"Director Li, Expert Guo, in fact, the cause of the failure of this printed circuit plug-in board has been found out."

Section Chief Tang said: "It is caused by the disconnection of the magnetic circuit below. In order to repair this fault, our factory currently faces two difficulties: first, it needs to be disassembled; second, due to the lack of welding required for the fine magnetic circuit.

Special micro-precision welding equipment and special solid soldering paste cannot complete the repair of the broken magnetic circuit even if they are disassembled!"

After he finished speaking, he stared at Guo Yonghe intently, preparing to see what kind of reaction the young expert Guo would make.

"hehe,"

After hearing this, Guo Yonghe laughed and said: "So you are stumped by such a simple problem? I originally thought it was some huge fault, but I didn't expect it to be such a simple problem!"

"What? You said this question is easy?"

Section Chief Tang's eyes widened in surprise.

"It can't be said that it's simple. The scorer depends on who is right!"

Guo Yonghe shrugged his shoulders and said: "For example, this question is not simple for me, but very simple."

"What? Very simple? What a shameless statement!"

Zhang Jianshe couldn't bear it any longer and said to Guo Yonghe: "Expert Guo, please tell me first and take it down!"

,stic leaded chip carrier is a plastic chip carrier with leads and is an integrated component that integrates a chip.

The printed circuit boards of industrial computers are large printed circuit plug-in boards, which are very dense, with very small distances between them, and are densely soldered to the circuit substrate.

It is almost impossible to remove it from the circuit board without damage. Before the mid-1980s, foreign countries usually used forced air convection heating to melt the soldered contacts and remove them.

This operation is extremely tedious and tests one's skills and patience. Except for some foreign master-level professional restorers, few people can do it.

Until the late 1980s, when disassembling and installing soldering equipment, the temperature control device in the equipment could be used to heat the soldering point to 210 degrees Celsius, so that it could be disassembled without damage.

However, this kind of special equipment produced by Wilo Company is not only expensive, but also has a very small output. It has not been introduced in China at all. In this case, can it be disassembled safely?

Zhang Jianshe had just heard Section Chief Tang give a detailed explanation, so it was very simple to listen to Guo Yonghe's explanation at this time, and he couldn't help but question Guo Yonghe.

"Haha, Director Zhang is really good at planning!"

Guo Yonghe sneered, "You didn't even discuss the maintenance fee, but you just wanted to get the maintenance plan out of me. Do you think I'm young and think I'm easy to deceive?"

"you you you!"

Zhang Jianshe was choked by Guo Yonghe and was speechless.

Conscience of heaven and earth!

He had no idea of ​​applying Guo Yonghe's repair plan at all, he just dismantled it safely!

"Okay, Expert Guo, don't get me wrong, Director Zhang definitely doesn't mean this!"

Li Weijin couldn't just watch Zhang Jianshe being so angry, so he quickly stood up to smooth things over, "As for the maintenance cost, what do you think is appropriate?"
