"Oh, hello! My name is Lu Jing. Lu Jing stretched out his hand, and Li Daqing changed the black metal camera to his left hand, and reached out to shake Lu Jing. There was Du Weicheng between the two, and when he saw that Lu Jing seemed interested in chatting with Li Daqing, he said to Li Daqing: "Let's change seats, so that it will be easier for you to chat." ”

Li Daqing hurriedly said: "Thank you, big brother!" As he spoke, he handed the camera to Lu Jing, "Come, buddy help me take it down, it's inconvenient for me to change seats." He unbuckled the safety buckle and switched positions with Du Weicheng.

Lu Jing took the camera with a smile, and the camera was still in the mode of taking pictures. Lu Jing unbuckled the safety buckle, stood up first, and gave up the space.

Li Daqing quickly changed positions with Du Weicheng, took the camera from Lu Jing's hand, and said to Lu Jing very enthusiastically: "Dude, what are you doing?" I see that you have a calm bearing, a bit like a leader, but your face is too young. ”

Lu Jing smiled: "How can it be a leader?" I'm in business, selling mobile phones. Tell me what direction you're studying. I'm interested in electronics. ”

Li Daqing smiled and hung the camera around his neck, "In the direction of microelectronics, professional knowledge is very boring and not interesting. ”

Lu Jing took out his mobile phone and said with a smile: "A mobile phone is an electronic product, assuming that we want to develop and design it ourselves in China, in your eyes, is it possible?" ”

Li Daqing's eyes lit up when he saw the mobile phone in Lu Jing's hand, and he took it and fiddled with it a few times, "It's a good mix." I'm not interested in circuit design, I'm working on process technology. It is a technology that uses micron-level processing technology to manufacture micro-miniature electronic components and miniaturized circuits on semiconductor material chips.

Microelectronics process technology is the technology inside the chip. Digital mobile phone chips are one of the main directions of the application of microelectronic technology, and I have learned about them.

A mobile phone chip is a group of chipsets based on the baseband chip of a mobile phone. The research and development of baseband chips for mobile phones cannot be developed in China for the time being. At present, there is not even a 35nm wafer production line in China, and there is no way to talk about baseband chip technology.

The baseband chip of the mobile phone includes the microprocessor (CPU) of the core component, the design of the microcircuit, the microcircuit process, and the wafer as the carrier, which are all basic parts. At present, there is still a long way to go from abroad. ”

Speaking of the knowledge related to his professional field, Li Daqing spoke very steadily, not like he just spoke, giggling and laughing.

"Yes." Lu Jing nodded, what Li Daqing said, he naturally knew. The most important core technology of mobile phones is the baseband chip. South Korea's Samsung has invested heavily in the research of baseband chips three times, and finally succeeded.

On the basis of the mobile phone baseband chip, the integration of power management chips, RF ICs and other auxiliary chips constitutes the mobile phone chip. A mobile phone chip is actually a collection of chips, and its core component is a baseband chip. Various models of mobile phone chips from various manufacturers differ in performance and functionality.

But just because you have a phone chip doesn't mean you can assemble a phone. The mobile phone chip should be integrated on the PCB board of the mobile phone, the peripheral circuit of the mobile phone chip, including chip capacitors, chip resistors, chip inductors, etc., and crystal oscillators, audio codecs, pickups (microphones/MIC), speakers, card slots (SIM cards), image processors (DSP), connectors (various terminals), TFT display (mobile phone screens) and other electronic components, so that the circuit board used to assemble the mobile phone is combined after combination.

These hardware technologies, together with the system software and functional software of the mobile phone, can be collectively referred to as the mobile phone platform solution.

Mobile phone platform solutions have always been a big killer for foreign mobile phone manufacturers. Foreign manufacturers will not open up their mobile phone platform solutions to domestic companies at all. Domestic mobile phone manufacturers can only explore and learn by themselves. Steal from others when they provide after-sales service and technical support.

In the early days of Unicredit, the domestic mobile phone was directly taken from the mobile phone circuit board provided by foreign manufacturers, and then assembled the mobile phone shell, battery, buttons, screen, and pasted its own brand to become a domestic mobile phone, and entered the market to make a lot of money.

"Do you have any friends who know each other and understand circuit design? At present, mobile phone chips are imported from abroad, and it is not possible to develop them for the time being, requiring a large amount of capital investment and talent reserves.

And the mobile phone design starts with the mobile phone chip at the beginning, which is too long, I think we can start with the mobile phone platform solution, and cut into the mobile phone field from the two directions of hardware and software. ”

Don't underestimate mobile platform solutions. In the future, the famous Apple company can even apply for technical patents for the rounded corner design of mobile phones, not to mention how many patents can be applied for on the design of electronic circuit boards.

If you want to become an excellent mobile phone manufacturer, relevant technology patent reserves are indispensable. I don't know how many pits there are waiting for the landing scene to jump down, it is very likely that a problem has been solved with great difficulty, and it turns out that foreign mobile phone manufacturers have applied for patents, either pay patent fees, or have to change the way.

In addition to the deep level of technical patents, from a technical point of view, it is also very difficult to develop a feasible mobile phone platform solution. Are there any defects in the functions of the software?

Problems such as crash, black screen, call quality, battery standby, size and thickness of the phone, screen display, running speed, etc., are all obstacles that need to be solved one by one.

Success doesn't happen overnight.

Li Daqing was stunned for a moment and said with a smile: "It turns out that you want to make a mobile phone." ”

Lu Jing smiled and stretched out his hand, "Reacquaintance, my name is Lu Jing, the person in charge of Jinghe Electronics Co., Ltd., and I am currently engaged in the agency work of Nokia mobile phones in Jiangzhou." I intend to set up a R&D team to develop mobile phone platform solutions based on mobile phone chips. ”

Li Daqing held Lu Jing's hand, shook it, and said with a smile: "I can't see it, I can't see it, you are too young." Okay, call me next time you go to Jiangzhou, and I'll introduce my classmates to you. Let's see if you can talk. ”

Lu Jing and Li Daqing exchanged phone numbers. Li Daqing pointed to the beautiful stewardess who was pushing the dining cart not far away and said, "Hey, I didn't expect the beauty to get her phone, so I got your phone first." Do me a favor, let's change seats, I'll sit outside, it's easier to talk. Help me take the camera. ”

"Okay!" Lu Jing smiled, took the camera, stood up, and saw that the stewardess who was pushing the food cart two meters away was the most beautiful stewardess in the entire crew. She turned around to get a drink in the dining car, and a pair of bright water pupils just saw Lu Jing looking at her intently, and she saw that the camera in Lu Jing's hand was facing her, and the smile on her face became lighter and fainter.

Lu Jing and Li Daqing changed positions and sat down again. The flight attendant's dining car also arrived at the front of the seat.

"What kind of drink do you need, sir?" The voice of the beautiful stewardess is like the cry of a nightingale, which is pleasant to the ear.
