Chen Zhouyi also urgently convened an internal meeting when he returned to the factory to discuss the attitude of Jiangxia Electronics Factory to deal with this wave of foundry.

Similar to the mood of the Jiangxia Electronics Factory, the cadres of the radio factory also expressed considerable hostility towards the Jiangxia Electronics Factory, believing that the recent poor efficiency of the radio factory was the fault of the Jiangxia Electronics Factory, and that the radio factory must take advantage of this opportunity to slaughter the Jiangxia Electronics Factory.

"We must set the OEM price to the highest, the highest!"

More than one person shouted so.

……

At the same time, in the semiconductor laboratory of Jiangxi University of Science and Technology, the test experiment on VCD chips has come to an end, and Li Xing told Zheng Nan that the best chip designs and corresponding decoders have been selected in theory, as well as the configuration of limited amplitudes.

"It can ensure that it can work normally in most cases, even if there is a slight short-circuit damage, etc., and it can also ensure that the main function is not affected."

Zheng Nan took the chip from Li Xing's hand, which was a palm-sized integrated circuit with a logic circuit composed of hundreds of copper wires densely arranged on it.

Although it is not quite the same as the top-notch high-tech chips that later generations understood, this is the chip of this era.

Li Xing kept introducing the partitions on the chip to Zheng Nan, explaining which partition corresponds to what function, Li Xing told Zheng Nan: "Although this chip can be installed on a VCD for use, I personally suggest that it is best to produce precision instruments." ”

Li Xing spoke very carefully, he didn't know what Zheng Nan talked about with Chen Zhouyi, and even he didn't know if Zheng Nan would accept to cooperate with Chen Zhouyi, after all, he couldn't accept a villain like Chen Zhouyi if he wanted to change it.

Zheng Nan reassured Li Xing: "Don't think so stingy as I think, I have already talked to Chen Zhouyi, and cooperation can be reached in principle." ”

Li Xing breathed a sigh of relief, at this time Xiao He came over to inform that the first VCD prototype had been assembled, Zheng Nan was very active to see Li Xing, and Zheng Nan was still running in front of Li Xing.

Walking into the office in the middle of the room, Zheng Nan saw a boxy gray-red iron box placed on the table.

Zheng Nan scratched his head, he could only say that Professor Zhou Minde and Li Xing deserve to be sisters and brothers, and this rough aesthetic is definitely the same teacher.

Zhou Minde connected the VCD to the TV, handed over a big brother-like square box to Zheng Nan, and told Zheng Nan to equip the VCD with an infrared remote control as required.

Zheng Nan took this thing as thick as his forearm, and was really dumbfounded: "Professor Zhou, does this remote control have to be so big?" Can you make it smaller, like a calculator? ”

Zhou Minde nodded and said that it could be reduced, but it couldn't be so small: "Because of the volume of the infrared emitter, the smallest is also a quarter of the size of this." ”

Zheng Nan made a slight comparison, although he still couldn't reach his ideal appearance, but considering this era, it could only be like this.

Then Zhou Minde opened the VCD and put it into the disc, Zheng Nan found that he actually used the clamshell type, so he immediately asked Li Xing if he could make it into a throughput type, and the production of the disc was not troublesome.

Li Xing replied that these two points are not a problem, the throughput type and the clamshell type are just a difference in design, the production of comparison chips is a small problem, the production of discs requires a special recorder, and you can use the recorder on the market.

Zheng Nan was relieved, and the subsequent test work was also very smooth, due to Zheng Nan's requirements, this VCD function is no different from the market in later generations, not only has the basic functions of the left and right channels to cancel the original sound and the on-demand menu through the remote control, and even added reverberation, bass and applause cheers and other functions.

is worthy of being a professor in a semiconductor laboratory, this ability is really not enough.

Li Xing took out a piece of hand-drawn paper and handed it to Zheng Nan, telling Zheng Nan that the chip design structure had been determined and could be handed over to the radio factory for production samples.

Zheng Nan took the drawings and hesitated for a moment, he asked Li Xing if the chip was not easy to be reverse-engineered, or leaked.

Li Xing told Zheng Nan that he had made a special design for the chip: "For example, this one, this is the circuit we used for testing, we still keep it for him, and these redundant circuits are also easy to mislead, I am confident that even if the other party uses laser scanning to violently copy, it will take at least three months to crack." ”

Zheng Nan nodded silently, he knew that the semiconductor technology in these years was not complicated, but it was easy for a senior engineer to reverse engineer it, otherwise the original VCD would not have been launched in less than two months, and it would have been flooded everywhere.

It can be said that Li Xing's ability to achieve such a guarantee is already the limit.

Taking away the chip drawings, Zheng Nan and Li Xing went straight to the radio factory, Chen Zhouyi personally greeted him at the gate of the factory, and Zheng Nan followed Chen Zhouyi to the lithography workshop.

The lithography workshop is a nesting doll structure, the outside is an ordinary electronics workshop, and there is a special isolation room inside as a chip workshop, Chen Zhouyi explained to Zheng Nan that this is to ensure the quality of production and not let a particle of dust enter as much as possible.

Zheng Nan nodded in understanding, and he handed the drawings to the engineers of the radio factory.

The engineer's surname is Liu, a middle-aged man in his fifties who looks very serious, he took the drawings and looked at them a few times, then frowned and looked at Zheng Nan: "Director Zheng, is this the final design draft?" How do I feel that there are a few areas where the circuit design is strange? ”

He also looked at Li Xing, obviously questioning the level of this peer.

It must be said that the radio factory has a lot of technical accumulation, and from this glance alone, this engineer Liu is capable.

Zheng Nan told him with a smile: "This is the final draft, you don't have to change it, just make it according to it." ”

Liu Gong looked back at Chen Zhouyi, Chen Zhouyi nodded and told him that everything was according to what Director Zheng said.

"Well, if the results I make do not meet the requirements, I suggest that Director Zheng should reconsider the design issues."

Although he accepted the drawings, Liu Gong still warned Zheng Nan, which shows that he is a principled person.

Chen Zhouyi smiled and asked Zheng Nan not to be surprised, saying that this Liu Gong is a dead brain, with a very strange temper, and no one in the factory can get a piece with him, but Chen Zhouyi also emphasized: "But Director Zheng, don't worry, Liu Gong's technical level is not to be said, it is the best master of our radio factory, and the satellite chips that went to the sky were made by him!" ”

Zheng Nan smiled and said that he could understand: "It's normal for people with skills to have a weird temper." ”

In fact, Liu Gong tinkered with the drawings on the workbench for a while, and then made a mask.

According to the lithography process introduced by Chen Zhouyi, the mask is equivalent to a template, and the template can be used to mass produce chips.

Liu Gong cautiously came over with the mask, and finally confirmed it with Zheng Nan before changing into a special dustproof suit and walking into the chip workshop inside with the mask.
