Chapter 525 Trial-produced PHS mobile phone (1) [seeking subscription]
The decision of Bai Yulin and Sun Kangmei made Zhu Chengxia hesitate.
Suddenly she faced two choices. One was to immediately transfer to the General Affairs Office of Nan'an University of Technology, and the transfer orders had been down; the other was to be promoted to a senior regiment official of Nan'an University of Technology and enjoy the treatment of section-level leadership.
Happiness came so suddenly that she didn't know how to choose, so she had to call student Xu Zhenming.
Xu Zhenming is currently busy trial-manufacturing the PHS project, and indeed he cannot be cloned."Nan'an Technical School will be annexed by Nan'an University of Technology sooner or later! Teacher Zhu, which path do you think is more appropriate?" He thought for a moment and told Zhu Chengxia the direction of education reform.As for how to choose the path of life, let Zhu Chengxia choose.
Hearing this kind of news, Zhu Chengxia was shocked and surprised that Xu Zhenming could grasp such confidential information.
"I'll go to Nan'an University of Technology! Just to help you manage the 10 million yuan donation fund!" After thinking about it, she decided to follow Xu Zhenming's pace, and the progress should be faster.
On this side, Xu Zhenming hung up the phone and called Zhang Guoli's team together to prepare for a meeting.
Zhang Guoli and others have returned from Wanwan and brought back PHMA base station chips, Abis communication interface chips, TTDMA communication baseband chips, ADPCM chips, PHS host chips... etc.
With these chips, Yiming Group can immediately trial-produce a set of experimental mobile communication systems such as PHS base stations, base station consoles, and PHS mobile phones.
Once this system is successfully tested, it marks that the country has immediately stepped into the G2 era and is in line with international standards.Moreover, the PHMA communication method has the same signal strength as GSM, and it can be promoted nationwide.
Therefore, Xu Zhenming attaches great importance to the development of this set of mobile communication systems, and specially convenes a technical meeting and discussion meeting.Those attending the meeting included Ma Jimin, Zheng Cheng, Sun Ziliang, Xiao Guohong, Liu Yangde and Zhang Guoli.
"Everyone! In order to speed up the tape-out of the chip, I deliberately chose to tape out the MPW mode and took back dozens of sets of PHS system chips. Now, the PHS system chips have been tested and there is no problem. The following is how to try this product Up!"
After everyone sat down, Xu Zhenming presented tasks to everyone present.
Ma Jimin’s team is responsible for opening molds for PHS mobile phones and making electrical box enclosures for communication base stations, base station consoles and other equipment.
"Report to Mr. Xu, we have no problem here! The parts processing workshop specially prepared for Chaoming Company has been completed. Injection molds, punching dies, cutting molds... etc. have all been made, ready for trial production!" Xu Zhenming just said After that, Ma Jimin took the notebook and began to report the production progress of the spare parts of the PHS system.
His spare parts are the foundation to ensure the progress of the development of the PHS project.
"Um...very good! Minister Liu, how about the procurement of spare parts on your side?" After hearing Ma Jimin's report, Xu Zhenming nodded with a smile, and then asked Liu Yangde about the procurement of electronic components.
Yiming Group is responsible for the research and development of the PHS system, so the purchase of accessories is not very large.Therefore, it is relatively difficult for Liu Yangde to purchase spare parts, and many international brand-name companies simply don't like him.
"Report Mr. Xu! Spare parts such as capacitors, resistors, transistors, etc. are not bad. We used to purchase frequently and have already stocked them. However, there is a problem with the PHS mobile phone battery, and it has not yet arrived!"
Liu Yangde smiled bitterly and told Xu Zhenming that the battery factory that supplies Motorola mobile phones is not very interested in Yiming Group's orders and that the delivery time is not guaranteed.
Upon hearing this, Zhang Guoli and others frowned.He suggested to Liu Yangde: "Minister Liu, if you go to Wanwan, there are many electronic spare parts factories, and you should be able to find suitable mobile phone batteries."
In order to save trouble, Zhang Guoli’s team directly chose the mobile phone batteries of Motorola’s Big Brother and 8900, and standard nickel-cadmium batteries for the PHS system.He didn't expect that there was a big problem in this link. What if the mobile phone battery is not available for mass shipment in the future?
Regarding this issue, other personnel are not very professional, and can't think of a good countermeasure for a while.
Xu Zhenming vaguely remembered that there was a cell phone battery king in Pengcheng, Eastern Guangdong Province.This person was also from Anhui Province and later founded the BYD Automobile Company.
Thinking of this, he looked at Liu Yangde and frowned slightly and said: "You are ready to go to Pengcheng on a business trip and find a cell phone battery company named Biati! The bosses of their company seem to be Wang Chuangfu and Lu Xianyang. After finding them, invite them to Nan'an City to discuss the supply of mobile phone batteries!"
"Yes!" Liu Yangde recorded BYD's information and contacted their company after preparing for the meeting.
On this side, Xu Zhenming and others have discussed how to produce the PCB circuit board of the PHS mobile phone, the PCB circuit board of the PHS base station and the PCB circuit board of the PHS base station console.
"Report to Mr. Xu! The PCB board automatic production line and PCB automatic assembly production line have been installed and ready for trial production!" At this time, Zheng Cheng, who was responsible for installing the two production lines, reported the results to Xu Zhenming with a relaxed expression.
The production of PCB boards requires professional CAD software to design circuit diagrams. The CAD software provided by the automatic production line is used to transform drawings, typeset survival circuit diagrams and typeset files, and finally input to the light plotter to produce the film of the circuit diagrams.
The CAD software of the imported PCB production line is all in English, which is a bit cumbersome to operate.
As a result, Xu Zhenming turned his face sideways, and his eyes fell on Xiao Guohong's face."Do you have any questions?" He asked Xiao Guohong with a serious expression.If Xiao Guohong has difficulty, Xu Zhenming is going to ask Zhang Guoli's team to support him and train several operators for the CADCAM system of the light plotter.
"Report to Mr. Xu! I have already trained two operators for the CADCAM software of the light plotter! Hey... Mr. Xu, the principle of this light plotter is actually very simple. Our company can imitate it, and it should not be difficult!"
However, Xiao Guohong grinned and said about his process of exploring the principle of the light plotter.
"Report to Mr. Xu! Our team also thinks that the principle of the light plotter and the film exposure machine is very simple!" At this time, Zheng Cheng, who was responsible for the installation of the equipment and the imitation production line, also reported the situation with a smile.
"Huh?" Xu Zhenming put down the pen in his hand and looked at Zheng Cheng with interest, letting him continue to report on the experience he had gained.
"The light plotter is a CAM device, and the principle is very similar to our company's computer cutting machine! It can be driven by our company's CNC system."
"The cutter of this equipment is a laser beam. The CNC system of the photoplotter converts the processed CAD drawings into raster data. The raster data drives the laser beam to irradiate the printed circuit board graphics onto the film and expose the film. , Leave the image of the circuit board!"
"The principle is actually very simple, but there are three major difficulties. First, the laser light source needs to be developed; second, the sealing of the film exposure chamber must be handled well; the third is very important, the CAD software is converted into the Gerbei format light drawing data algorithm and raster data The development of processor chips!"
"As long as the above three problems are solved, our group company can manufacture high-precision light plotters!"
Zheng Cheng held a notebook, reporting and analyzing one by one.
"The raster data processor chip is just an ASIC code algorithm chip, and our team can solve it!" At this time, Zhang Guoli stated on behalf of his team that he was ready to undertake this task.
The rest is to develop mechanical architecture systems for gas lasers and photoplotters.
The mechanical structure system is very simple for Yiming Group, and its machining accuracy is second to none in China.Otherwise, Xu Zhenming would not dare to establish a five-axis linkage CNC machine tool, a national key project.Therefore, this issue can be directly handed over to Zheng Cheng.
As for the laser light source, Xu Zhenming is going to hand it over to the Jiangxia Optical Research Institute of Changgong Group.This unit can manufacture laser defense equipment and develop a civilian gas laser. It should not be difficult.
In this way, after such an analysis, the localization of light plotters is just around the corner.
"Okay! Let's set up a project to develop a light plotter today, and the Zhengcheng team is responsible for hosting it!" Thinking of this, Xu Zhenming decided on the light plotter project on the spot.Therefore, this product must be localized many years in advance.
Having said this, Xu Zhenming glanced at Zheng Cheng again and motioned him to continue reporting on the film exposure machine.
"Let me talk about the principle of the film exposure machine! The principle of the film exposure machine is very similar to that of the printing machine. The circuit diagram is printed on the copper foil circuit board coated with photosensitive material with an ultraviolet light source!"
"The first step is to coat a layer of photosensitive material on the copper foil substrate; the second step is to turn on the ultraviolet light source to project the circuit diagram film onto the substrate, and the photosensitive material is irradiated with light to dissolve; the third step, the non-photosensitive part of the resin is in the developer It does not polymerize or dissolve under the action of the light-sensitive part, and the resin in the photosensitive part remains on the substrate to form an image."
"The film exposure machine is a CAM device that integrates electronic optics, electrical, mechanical, vacuum, and computer technology. It is slightly less automated than our computer cutting machine."
"For us, the most critical component of this equipment is the control of the ultraviolet lamp light source and the control of preventing ultraviolet radiation. As for the positioning of the copper foil substrate, the movement of the copper foil substrate, etc., it is very simple!"
All of you present here are experts in CAM equipment. Therefore, Zheng Cheng's introduction is very simple, only to introduce the difficulties of the film exposure machine.
Hearing what he said, Xu Zhenming felt that this kind of equipment is the easiest to manufacture. UV lamps can be purchased as finished products. For other mechanical structure systems, Yiming Group can modify the design according to the frame of the computerized embroidery machine.
"Mr. Xu! We can produce this kind of equipment!"
"Mr. Ma is right! As long as we can buy the same type of UV lamps, the film exposure machine we produce will definitely not be worse than that of foreigners!"
After listening to Zheng Cheng’s explanation, Ma Jimin, Sun Ziliang, Xiao Guohong and others all expressed their opinions, believing that the group company can immediately establish a project to develop a film exposure machine.
As a result, Xu Zhenming immediately announced the establishment of a PCB automatic production line research and development team, with Zheng Cheng as the team leader, and began to develop a PCB automatic production line including a light plotter and a film exposure machine.
As for the production of the PHS system circuit boards, Sun Ziliang and Xiao Guohong are responsible.
