Chapter 980 Plug-in machine

In the early morning of the second day, Duan Yun first came to the electronics factory.

"Master Zhao, good morning!" Seeing that Zhao Xuewu brought several new technicians to test the equipment in the workshop, Duan Yun greeted him immediately with a smile on his face.

"Morning Manager Duan!"

Seeing this, these people also greeted Duan Yun one after another.

"How is the modification of this rotor winding machine?" Duan Yun asked, pointing to the winding machine in front of him.

"I have redesigned a new circuit board. After the trial yesterday, the four shuttle heads can be started at the same time, but the speed stability is still not in place, and a frequency regulator needs to be installed..." Zhao Xuewu pointed at the back of the machine The newly replaced circuit board said to Duan Yun.

Zhao Xuewu's attainments in electronics are still very high. He has now figured out the principle of this camera and made a new circuit board. However, the new equipment requires repeated commissioning and experiments, which requires a certain amount of time and effort. process.

"Very good." Duan Yun nodded in satisfaction, and then asked: "How is the development of our new recorder going?"

"According to the idea of ​​single-motor drive proposed by you, Manager Duan, we have designed a new product plan in the past few days, but the production is very difficult. On the one hand, a new type of motor is required, and on the other hand, the design of the circuit board is relatively complicated. If It is very time-consuming and labor-intensive to produce in batches, and it is difficult to control quality problems..." Zhao Xuewu said with a frown.

"Quality control is more difficult?" Duan Yun asked.

"If we want to produce small tape recorders, we must strictly control the area of ​​the circuit board, but because of the use of a single motor drive, we need to design a new electronic servo control mechanism, which means that more electronic components need to be added to the circuit board. If there is no integrated In the case of chips, the layout of the electronic components on the electronic version of the small tape recorder will become very dense and compact. If it is assembled by hand, the process requirements are very high, but there are many electronic components that need to be soldered, which greatly reduces the assembly efficiency and is also easy. If you make a mistake, it is very complicated to check..." Zhao Xuewu said.

With the ability of Zhao Xuewu and others, it is not difficult to design a single-motor servo circuit board. The difficulty lies in how to produce a high-performance motor, and how to simplify the circuit design and improve production efficiency.

So some time ago, Zhao Xuewu and others met every day to study the design plan, and they had simplified the design drawings to the greatest extent, but they still could not reach the ideal level. It is no longer possible to simplify the design of the circuit board of the card recorder.

As for the high-performance tape recorder motor, it is also a problem that several old professors of the research institute have recently focused on solving. Through their hard work in the past few days, they have successfully made new circuit boards to replace the original "castrated" Japanese second-hand production line circuit boards. It's just that because of the inability to obtain high-performance chips, the performance of the device cannot be maximized.

It can be said that at this point, the objective condition that restricts the success of Duan Yun's new tape recorder production line is the backwardness of domestic electronics industry technology. Domestically produced chips have a low yield rate, poor quality, expensive price and a huge gap with foreign countries in performance, which is simply unbearable. Therefore, unless Duan Yun can obtain foreign high-end chips, otherwise, the production line he introduced will not be able to exert its maximum effect.

"Master Zhao, you can tell me what high-end parts and chips you need. It's best to make a list in the next two days, and I'll help you solve them." Duan Yun said after thinking for a while.

"Can you buy integrated chips?" Zhao Xuewu was stunned when he heard this.

In the 80s, although China and developed countries in Europe and the United States were in the honeymoon period, in order to maintain their technological advantages, it was impossible for developed countries to sell some advanced technical chips to China. Even if they wanted to buy some low-end chips, it was very difficult. , Zhao Xuewu still has a better understanding of this point, because when he was teaching at the Taiyuan Institute of Mechanical Engineering, he had to write an application and make a report if he wanted to obtain a chip for experimentation. Even so, most of his reports were like nothing. It can be seen how difficult it is to obtain an imported foreign high-performance chip.

"It's difficult to buy advanced chips in batches, but if only a small amount is used for our equipment circuit boards, maybe I can figure out a way." Duan Yun said with a spread of hands.

In fact, there is only one way for Duan Yun to obtain this high-end chip, and that is his office in Xiamen.

Duan Yun’s current Xiamen office has established a relatively stable business relationship with Xiamen Yuanfang Company. Before the high-end subwoofer speakers produced by their factory, some of the integrated chips were obtained through Xiamen Yuanfang Company, and the other part was obtained through Gao Lei’s side. Although Gao Lei may have gone to Hong Kong at present, this channel has not been broken. The company set up by Gao Lei in Guangzhou is currently being continued by his subordinates.

Duan Yun obtained two high-precision digital processing centers through Xiamen Yuanfang Company before. These two devices were obviously strictly prohibited from being sold to mainland China by developed countries, but Yuanfang Company still moved the two digital processing centers through Ant The processing center was successfully shipped back to China.

Since even such high-tech machine tools can be smuggled in, small chips should be no problem. Besides Xiamen Yuanfang Company, Zhao Changfeng has now found more gray channels in Xiamen. As long as the price is high enough, there will always be many People are willing to take risks and "bring goods".

"If I can really buy advanced integrated chips, I can guarantee that this production line will be refitted in advance!" Zhao Xuewu said confidently.

"Well, you have a meeting with everyone tonight, make a list of the chips and parts you need, and hand them over to me tomorrow morning." Duan Yun thought for a while, and then said: "By the way, where is Master Peng?" ?”

"Professor Peng is at the machinery factory now, what do you want to do with him?" Zhao Xuewu asked.

Peng Changming is five retired faculty members, and the only professor of the Department of Mechanical Engineering. After Duan Yun returned to Shenzhen this time, he devoted all his time and attention to the electronics factory and rarely went to the machinery factory to check, so when Duan Yun asked When he arrived at Peng Changming, Zhao Xuewu felt a little surprised.

"I have another plan..." Duan Yun pondered for a while, and then said to Zhao Xuewu: "Master Zhao, how much do you know about plug-in machines? Have you used this thing before?"

"Plug-in machine?" Zhao Xuewu was stunned when he heard the words, and asked repeatedly: "Do you want to develop a plug-in machine?"
