In the blink of an eye, it’s afternoon...

Yang Ziye in the laboratory called Cao Mang. The prototype was made and tested, and he asked Cao Mang to go to the laboratory to take a look at it when he was free.

Cao Mang had nothing to do, so he and Shi Hao went to the laboratory.

"Mr. Cao, are you satisfied with the prototype of the stand? The screen uses a 3.4-inch ASV screen, which is Sharp's most advanced technology at present, with a resolution of 480x854. The camera uses Sharp's 1.3 million pixel S, and the battery is mine. Wei Zhaosheng

Made for me, the capacity reaches 1600 mAh, the longest standby time is 30 days, and the continuous talk time is 13 hours. Because of the new battery and chip, the thickness of the whole machine is reduced by 4 mm, and the weight of the whole machine is reduced by 38 grams.

." Yang Ziye introduced.

Because the body is made of brushed aluminum alloy, the appearance of the entire mobile phone is silver-white. When you open the screen, you can see the buttons of the mobile phone, which are made of pure black buttons.

There is a 3.5CM headphone jack on the top of the flip cover. The battery can be removed by removing the back cover. Below the battery are the SIM card and memory card.

Cao Mang put the battery back and turned the phone on again.

The booting speed is very fast, and it takes only five seconds to enter the mobile phone system desktop.

Press the function key in the center of the keyboard to enter the system menu.

Cao Mang turned on Qilin Music to play...

"I'm looking at...the moon..."

The sound of the mobile phone speaker is loud and loud, just like the copycat phones of later generations.

While playing music, Cao Mang turned on the camera function.

"Pah~pah~pah~"

He took a few random photos of the laboratory and the results were pretty good.

"The speakers need to be improved. The popping sound is too serious. You can't just pursue loudness. The sound quality must also be guaranteed. In addition, the buttons on the mobile phone need to be replaced. These buttons are too uncomfortable to use. Replace them with floating buttons. The battery capacity can be reduced.

Let’s reduce it to 1200 mAh and see if we can reduce the thickness of the phone. This phone can’t play videos yet, so the screen resolution can be smaller, which can greatly reduce the cost.” Cao Mang said while playing with the phone.

Then he opened Qilin Chat. The overall smoothness was pretty good, and both sending and receiving messages were perfect.

"Mr. Cao, even if the battery is reduced to 1200 mAh, the thickness of the body will not be reduced much. It is better to keep it as a feature. We can design an ultra-thin mobile phone, which can enrich the product line. The speaker problem is not a big problem.

Yes, I can just replace it with a better one later. As for the keyboard problem, it can be easily solved. We can just customize it with the factory." Yang Ziye said.

"Design the battery to be non-removable, which can reduce the thickness of the fuselage." Cao Mang suggested.

"All mobile phones on the market have replaceable batteries. If we make them non-detachable, will it affect the user's use?" Yang Ziye asked.

"If I listen to music while chatting on Qilin Changchang, how long can the battery last?" Cao Mang asked.

"It can last for eight hours." Yang Ziye replied.

"It is impossible for users to play for a whole day. Eight hours of battery life is enough. The non-removable battery design can increase the internal volume ratio of the phone. You can redesign the circuit board and modify the shape of the battery. This will not only

Increasing the battery capacity can also reduce the thickness of the phone, and the integration can make the phone more refined in appearance." Cao Mang said as he handed the phone to Yang Ziye.

At present, it seems that there is no big problem, only small modifications are needed. As for the problem of the battery being non-removable.

Non-removable batteries are a major trend, which not only increases battery capacity, but also increases the safety of mobile phones and reduces the cost of mobile phone repairs.

Cao Mang drew a picture on the A4 paper and handed it to Yang Ziye and said, "You can refer to the design above."

The layout on the drawing surprised Yang Ziye. It turned out that a mobile phone could be designed in this way. He had never thought that if it was designed according to this method, the thickness could be reduced by another 5-6MM.

However, a new problem is coming. The accessories need to be re-customized, and communication with the factory is required, which will take at least a month.

"Mr. Cao, if we follow this design, we will need to re-customize the accessories, which will take at least a month." Yang Ziye said.

"Time is not a problem. You should also take this opportunity to practice hard. Open your mind and don't stick to the same old design plan." Cao Mang patted him on the shoulder and said.

"I understand, Mr. Cao." Yang Ziye nodded.

"Mobile phones will become more and more integrated in the future. You have to pay more attention to the level of integration. The work in the future will become more and more difficult," Cao Mang said.

Cao Mang felt his balls hurt when he saw the circuit board design done by Yang Ziye, it was like a piece of shit, but he had to comfort him and feed him chicken soup to make him work hard, otherwise he would have to do this kind of thing by himself.

The biggest headache for business owners is the inability to recruit and train good talents.

Yang Ziye and Uncle You Xin can only be regarded as interns to Cao Mang.

If the two of them can't keep up in the later stage, then Cao Mang will have no choice but to consider substituting.

...

Cao Mang had just returned from the laboratory when he saw Xia Guangmin in the corridor, and the two entered the office together.

Xia Guangmin put the documents in his hand on the table and said: "Mr. Cao, the bidding for the wafer factory has been completed. The total cost of factory construction and dust-free construction is 270 million."

Cao Mang opened the folder and looked at the contents of the file. The cost of factory construction was only 60 million, and the decoration of the dust-free factory was the major cost. A total of 210 million was spent.

The winner of the bid for factory building construction was China Railway No. 2 Bureau, and the winner of the bid for the dust-free project was a company in Shenzhen, Hongdi Purification Engineering Company.

"Approximately when can construction begin?" Cao Mang asked.

"As long as the municipal government's review is passed, the China Railway Second Bureau can start construction immediately," Xia Guangmin replied.

"You should keep an eye on it when Wuchen is decorating it. There can't be any mistakes in this matter." Cao Mang said after covering the document.

"I will keep an eye on it personally when the workshop is being renovated," Xia Guangmin replied.

Although this is Xia Guangmin’s first contact with dust-free decoration, after this period of research, he has a certain understanding of dust-free workshops.

Dust-free workshops have strict requirements for dust prevention, anti-static, and indoor humidity.

Especially those rooms where photolithography machines are placed. In order to ensure the accuracy of the equipment, this room must be in a vacuum state, and there are also strict requirements for shock resistance.

Even if there is just the slightest vibration, the lithography machine is likely to make errors, causing the chip yield to drop significantly, and ultimately causing immeasurable losses.
