Ye Jinhuo rushed to search for ancient books.

Ye Jinyu and the others were anxious and anxious, and they were in no mood to care about this matter, and when they were about to ask for another call to urge them, the mobile phone rang, and at a glance, it was Lu Yuwei calling.

"Boss, it's really rare, this time I can get through with a single dial." Xu Ye Jinyu has been absent from this time and space for a long time, and Lu Yuwei was surprised that she could dial his phone directly.

"What's the matter?" The boss who just ate a bold fire at Zeng Jianguo's place is not so easy to flirt.

"Uh-huh...... what, boss, I've negotiated the agricultural machinery factory, waiting for you to sign the contract." If there is time today, if there is any, we will go and end this matter by the way. ”

This is good news, Ye Jinyu immediately got interested and asked, "Yes, the efficiency is quite high!" ”

was praised by the local tyrant boss, Lu Yuwei was very useful: "That is, you want to buy it and you are not short of money, they are in a hurry to sell; When the dry wood and fire meet, there are countless victories in the world. The efficiency can't be slow, now there is a phone call a day, it depends on when we go to sign the contract and pay. ”

On the contrary, it was Boss Ye, who was a little uneasy when the contract was about to be signed at the end: "You said that they are in such a hurry to sell, will there be any problems?" ”

Lu Yuwei said: "There must be a problem, not to mention anything else, the efficiency of this factory is very bad, and the county financial subsidies are needed all year round, and when you receive it, you have to be prepared to lose money; Do you also know that if it is a hen that lays eggs, the local political axe will be willing to sell it? ”

Speaking of this, she hesitated for a moment, and then lowered her voice and said: "Boss, anyway, I was against it when you proposed to buy it, but the boss you insisted repeatedly, so I will talk to them." ”

"It's not that you can't buy it, I mean that this sale, and whether there will be traps in the contract or something."

It turned out that it was for this, Lu Yuwei said: "You can rest assured that this boss, I have been to see the venue, and I have also learned about the village, the community and the county, basically from the village to the town and then to the county, they all agreed to sell the factory for money." As for the contract, didn't you find Huang Yujie as the company's legal counsel? Pull her to accompany the whole process, although she is more sassy, but the professionalism is still okay. With her, you can put a hundred and twenty-four hearts in terms of contracts. ”

People are more sassy? Somehow, Ye Jinyu suddenly thought of the graceful Huang Yujie in the night of the first day......

Shaking his head, he shook all these miscellaneous thoughts out of his head.

Lu Yuwei put all the words to this point, and Ye Jinyu no longer hesitated: "Okay, sign it; But I'm going to have something to do, and I'll need to leave a little later; When the time comes, I'll call you, and you'll pick me up. ”

"Okay, you're the boss, you have the final say." Lu Yuwei is really used to it: "Then I'll wait for your news." ”

Just as he was about to hang up the phone, Ye Jinyu suddenly thought of something again, and hurriedly said: "By the way, does that factory have the ability to process circuit boards?" ”

Lu Yuwei was stunned for a moment, and paused for a while before saying, "Circuit board? I don't know, why don't I call and ask the person in charge of their factory? ”

Ye Jinyu couldn't, so he could only hang up the phone and wait.

A few minutes later, Lu Yuwei called back again.

"Boss, the agricultural machinery factory doesn't process circuit boards, but some of their products will use some small circuits, so there is a way to purchase circuit boards, if needed, they can provide the supplier's phone number, you contact them yourself."

This answer is not what Ye Jinyu wants, since the agricultural machinery factory does not provide it, then forget it.

"Okay, I see, you go and get busy; When I'm free in the afternoon, we'll go to the agricultural machinery factory to sign the contract. ”

After hanging up Lu Yuwei's phone, Ye Jinyu began to think about how to achieve mass production of circuit boards. The fastest way is to find a processing plant with a production line and let them do the processing; But this is a big problem for the secrecy of the runes.

After thinking about it, Ye Jinyu simply didn't want to, and waited for Zeng Ziguo to create a rune board to test whether it could be used and then have a headache.

It has been an hour since I went to the copy shop from China.

There were a lot of things in the big packets, tools like soldering irons, drills, resistors, capacitors, substrates and other parts, and even sulfuric acid and hydrogen peroxide. These are all Zeng Ziguo's harvests in the Electronic City, and he bought them out of his own pocket, waiting for Ye Jinyu to reimburse them.

The first time he saw Ye Jinyu, he grinned and shouted: "Brother Ye, Huozi, I'm here, have you eaten?" ”

There was no food to eat, and Ye Jinhui was so excited that he couldn't eat because he wanted to complete a big business; Ye Jinyu was so anxious that she didn't want to eat.

"Don't be in a hurry to eat, when the circuit diagram is ready, go to the restaurant!"

Zeng Ziguo also wanted to put the 10,000 yuan in the pocket as soon as possible, and agreed:

"Then let's get to work! Brother Ye, what about the circuit diagram? Where is it? ”

Circuit diagram?

Looking at Ye Jinyu's blank eyes, Zeng Ziguo knew that there was something big about it, and explained:

"To make a circuit board, we need to have a circuit diagram first, and we generally use PROTEl to design a circuit schematic and package it according to our needs; With this circuit schematic, we can generate the PCB net. With this network in place, the next step is to place the individual components according to the size of the PCB panel, ensuring that the leads of the individual components do not cross. After the components are placed, a final check is carried out to eliminate the pins or wires crossing errors of those electronic components during wiring, and all errors are eliminated before the final circuit diagram is determined. ”

There is no circuit diagram, but the runes are still stored in the computer.

Calling up a rune of a hanging talisman from the computer, Ye Jinyu said: "I want to print this on the circuit board, no problem, right?" ”

After studying the ghost drawing talisman repeatedly, Zeng Ziguo turned his head to Ye Jinyu to confirm: "Brother Ye, are you sure you want to print this into a circuit board?" There's nothing here, it's going to be short-circuited. ”

Ye Jinyu nodded affirmatively and said, "Just print this, you can say if you can print it." ”

Zeng Ziguoxin said that this time the 10,000 yuan seems to be going to be in vain, and even the tools he bought with money have to be smashed in his own hands;

I complained bitterly in my heart, but looking at Ye Jinyu's expression, I gritted my teeth and said, "Okay, let's start!" Print out this picture first. ”

Printing must be done on special carbon paper, but fortunately, these things have been prepared in advance. And there is no shortage of printers in Ye Jinyu's copy shop. The runes were quickly printed on the paper, and just in case, Ye Jinyu printed a few more.

After the pattern was output, Zeng Ziguo pressed the side printed with the circuit diagram against a copper plate. Then it is stuffed into the superplasticizer for hot printing, and the circuit diagram ink on the carbon paper is glued to the copper plate under the high temperature of the superplasticizer.

At this point, Ye Jinyu found that making circuit boards is quite similar to offset printing. The offset printing machine should make the rune diagram of sulfuric acid paper, and then cover the aluminum plate with ultraviolet light to leave a pattern on the aluminum plate, and finally transfer the pattern to the paper through the offset printing machine.

This is how the seals that were previously printed in batches were done.

I didn't expect to make a rune board now, it's quite similar; The rune pattern is printed on carbon paper, and then hot-printed onto the copper plate by a plastic machine. I just don't know what's next.

I saw Zeng Ziguo take out a few glass bottles from the bag.

"This is H2SO4, which is called sulfuric acid by the Jianghu people; This is H2O2, the scientific name is hydrogen peroxide, commonly known as hydrogen peroxide; Both of these things are very corrosive. ”

Ye Jinyu resisted the urge to slap him and said, "Don't be poor, I've only graduated from high school for a year, I remember these things, hurry up and take the next step." ”

Zeng Ziguo said with a smile: "Just kidding to liven up the atmosphere, hehe, Brother Ye, my brother's temper is a little stubborn, don't be like him." ”

"Ah, I don't have that time to talk to him, hurry up and move on to the next step." Ye Jinyu only wanted to know the result of the rune board now.

After all, it was dangerous goods, Zeng Ziguo stopped laughing, and began to prepare the solution, he was very careful to modulate the sulfuric acid and hydrogen peroxide according to 3:1; Then put the copper plate containing the ink in it, wait for about three to four minutes, and wait for all the places on the copper plate except the ink to be corroded, then take out the copper plate and rinse the solution with clean water in the toilet. A complete rune plate appeared in front of Ye Jinyu.

"Brother Ye, the board is ready!" After Ye Jinyu took it, he said: "Your circuit diagram is very simple, and you don't need electronic components; Therefore, there is no need to punch through the pins, let alone the time-consuming and laborious soldering of the pins. I just don't know what this kind of board can do. ”

The fabrication of the circuit board turned out to be as simple as that. The world's first rune board was so easy to complete!

After Ye Jinyu took it carefully, he didn't look at Zeng Ziguo, his attention was all focused on the rune board, and he just said on his mouth: "Xiao Zi, didn't you make a few carbon papers just now, why don't you help me get a few more boards, and I'll test this one." ”

To test this kind of metaphysical product, Ye Jinyu was supposed to go to Datang, but the power on Datang's side was not enough, so he avoided the cubicle first.

"Okay, Brother Ye, I bought five substrates, and I just made them all for you." Zeng Ziguo responded in one bite.

Ye Jinyu couldn't wait to walk to the cubicle with the newly produced rune board, and when he arrived at the door, he turned around and said, "By the way, Xiaozi, how much did you spend on buying things?" I'll give you the money later; Add another WeChat, and I'll transfer you 10,000 yuan. ”

As soon as he heard that Ye Jinyu took the initiative to mention the money, Zeng Ziguo's mouth opened and said, "Brother Ye, don't worry, I'll help you make the rest of these boards first." As he spoke, he energetically handed down a board.

As long as you are willing to give money, you can do whatever you want; Scrap a few boards for nothing!

In the cubicle, Ye Jinyu suddenly found that there was no hole in the pins of the rune, and it was a flat and neat board, which was not easy to wiring. I wanted to go out again and let Zeng Ziguo drill a hole, but seeing his busy figure, Ye Jinyu retreated to the compartment again.

Let's just test it on rune paper.

Connect the line, fix it with tape, and the power supply is also simple, Ye Jinyu still has a lot of electric car batteries in his compartment, and you can try it when you pick it up. Let's start with the low-voltage test.

With the mood of pilgrimage, Ye Jinyu suddenly turned on the battery.
