Ye switched off the main power supply of the TV, unplugged the power plug, carefully turned the TV head, so that the electron gun firing part of the picture tube was facing the outside, and then put the remote control motherboard circuit next to the main board of the TV in a convenient position for observation, signaling that these onlookers could enjoy it up close. Pen, fun, pavilion www. biquge。 info

Because, the remote control circuit is still in the testing stage, so, many of the connecting lines between the two circuit boards look very messy, only the electronic components on the remote control circuit board are arranged very neatly, so the young man directly ignored the direction of those connecting lines, but looked at the circuit board arranged very neatly with a thirsty gaze, bowed down, turned the circuit board over, carefully looked at the copper foil lines and solder joints shining with solder on this side, and had to sigh in his heart: worthy of being professional.

The onlookers didn't speak, just silently looked at the circuit board in front of them, Ye Kai knew that people who generally came to Yaliao Street were either here to repair and purchase finished electrical appliances, or they were electronics enthusiasts, while purchasing the electronic components they needed, by the way, they learned about the current electronic technology and new electronic components, and only the latter kind of people would be interested in the inside of the disemboweling TV.

Ye Kai is not familiar with these people, but he also vaguely remembers that in his previous life, many of the bosses who opened their own electronics factories were themselves electronics enthusiasts, and Yaliao Street laid a solid foundation for their careers. There is no intention to use it on the technical level of the factory.

Therefore, although Ye Kai does not have a complete plan for the future now, he also looks down on what these people did in his previous life, and more importantly, these people's technical foundation is not good at all, and they have their own opinions, which will not be of good help to Ye Kai's future thinking at all.

However, no matter what, Ye Kai is still very happy to have peers to appreciate his technical achievements now, maybe this is because of a common language.

Therefore, Ye Kai also answered the young man's various questions more patiently, but as Ye Kai's explanation deepened, several onlookers left one after another, and in the end, only a middle-aged man and a young man remained, and in the end, the middle-aged man also left, leaving only the young man alone.

Ye Kai didn't care either, and continued to communicate with the young man.

With the deepening of the exchange, Ye Kai has a preliminary understanding of this young man, the young man is called Wu Aiguo, from the mainland, a native of Dongguang, studying at Huaqing University in Jingbei, previously majoring in electronics, and now studying for a master's degree in computer science.

Through the exchange, Ye Kai has a further understanding of the level of Wu Aiguo's professional knowledge, for professional knowledge, Wu Aiguo is very solid, which is also the general performance of people in that era of hard work, and the practice is very poor, you must know that in this era, the shortage of electronic components, and how many imported components can be used by these students to practice independently?

Only graduate and doctoral students are likely to come into contact with these advanced technical entities under the guidance of their supervisors, and most of them are only engaged in auxiliary work and cooperate with their supervisors' research. And those expensive instrumentation have absolutely no chance of operating alone.

Therefore, Ye Kai also selectively said something relatively shallow, but it was definitely the knowledge that could not be learned in mainland universities to popularize Wu Aiguo.

You must know that there are only two levels involved in an electronic product, one is hardware, and the other is software. Hardware is a collection of various electronic components and integrated circuits on the PCB board, which is inseparable from the basic resistance, capacitance, and inductance, and there are ready-made calculation formulas to calculate the proportion and parameters of these components in specific circuits; The software, on the other hand, is more complex.

Therefore, when communicating, Wu Aiguo was a bit like listening to a book from heaven many times, but he still listened to it with relish, and asked Ye Kai for advice on the problems he usually couldn't figure out and was embarrassed to ask for help, anyway, he was a stranger from a distance, and he didn't care about losing face.

In the end, Wu Aiguo once again looked at the workbench opened by Xia Ye, and was about to leave, but he didn't want to inadvertently scan a black and somewhat familiar long IC on the workbench, which immediately attracted Wu Aiguo's attention.

"Ye Kai, what kind of machine is that black IC on the table?" Wu Aiguo asked with some expectation and some excitement.

"Oh, that IC you're talking about?" Following Wu Aiguo's guidance, Ye Kai saw the IC and replied casually. "It's just a 16-bit computer processor."

"It's just a 16-bit computer processor?" Wu Aiguo, who confirmed his conjecture, almost bit his tongue and stammered, "You... You... Where did you get it? ”

"My dad made this work." Ye Kai continued to answer nonchalantly. "It's useless."

If there are only one or two pieces like this, it is really useless, Wu Aiguo thought in his heart, he can only use it for testing experiments, since it is useless, what are Ye Kai and they buying it for? And it seems that this kind of electronic components are restricted from purchasing, and the retail market can't buy them at all, not only can't buy them, but also belongs to the ranks of the embargo for Hong Kong, which is across the river, right?

With this kind of question, Wu Aiguo asked: "Ye Kai, such a high-end CPU chip shouldn't be retail, right?" ”

"Of course you can't buy it in retail." Ye Kai replied lazily. "This is a batch of purchases from my father's trust, and now I haven't found a place for it, so I can only sit idle."

"A batch?" Wu Aiguo's heart is about to jump out, these are all treasures! Babies who can't usually see their backs, but today they don't want to say a batch from a teenager's mouth, these precious treasures!

"Ye Kai, how many chips do you have?"

"Probably 。。。。。。" When Ye Kai heard this, his eyes rolled up, and he carefully calculated in his mind before he said. "About 100,000 pieces."

"What? There are 100,000? When Wu Aiguo heard this data, people were going to be dizzy, and his mind was full of overwhelming chips flying there.

At this time, he thought of following his mentor to participate in a project of the Ministry of Electronics Industry in the second half of last year, and he was busy for 2 months, and a lot of drawings were drawn, but because this black chip had no way out, he finally had to stop the project.
