Chapter 148 Formulating a R&D Plan
"High-definition camera, fast charging, large screen, fingerprint recognition." Qiao Ruida wrote these words on a piece of A4 paper. These are the development directions of smartphones in the next few years. If they can all be realized, it will definitely create a best-selling model. cell phone.

"Large screens are easier to solve. Foreign Four-Star, Sharp, and domestic BOE can provide large screens of 5 inches or more. It would be better if they can be made into hole-punch screens or water-drop screens. Fast charging is not difficult to achieve. You only need to design a fast charging chip and a relatively good charging head to realize the fast charging function. However, the current lithium battery energy density is too low and the internal resistance is too large, so it cannot achieve a very fast charging speed. Then first Let’s set the target for fast charging at 18W, which is much faster than the 5W charging of Apple phones.”

"For high-definition camera modules that can be installed in mobile phones, you don't have to rely on domestic manufacturers. You can only find them abroad. There are two ways to implement fingerprint recognition on mobile phones, one is under-screen fingerprints, and the other is installed on the back or side of the fuselage. An independent fingerprint recognition module on the side. Under-screen fingerprint recognition must be realized with an OLED screen, and the current OLED screen is still very immature and will not be mass-produced within a few years. There are no mature products on the market to provide an independent fingerprint recognition module. , the R&D department needs to establish a project for research and development.”

"In terms of core hardware, the main control SOC and radio frequency chip are Snapdragon MSM8260 or MSM8660. The early version of Android is relatively small, with 1G of memory is enough, and the storage is 4G to 8G. It supports memory card expansion, which is enough for use. The screen is at least For LCD screens of 5 inches or above, the larger the screen-to-body ratio, the better, and it is best to make it a full screen. The battery is above 2500mah and supports 18W fast charging. The front camera is at least 500 million pixels, and the rear camera is above 800 million pixels. The higher the better. Okay. Forget about dual cameras and multiple cameras. After all, this is a first-generation product. You can’t go too far and leave room for upgrades for future products. The middle frame of the phone is made of metal, and the back panel is made of plastic or glass. Just block the signal.”

Qiao Ruida wrote and drew on a piece of white paper and initially formulated a smartphone configuration list. Then based on this list, he compiled a detailed mobile phone research and development plan.The current R&D department still has too few manpower to fully launch a smartphone research and development plan. It can only conduct preliminary research and development on individual components, such as fast charging chips.

Ten years from now, there will be a proliferation of various fast charging protocols, such as PD, QC, PE, FCP, SCP, PPS, etc., and various fast charging chips will also be easy to buy. Fast charging of 11 or 5W will not be difficult to achieve. .But it’s only been 5 years now, and smartphones are in their infancy. Apple phones still use 2W charging heads, and other brands of smartphones also charge very slowly. 18V[-]a is already fast charging.Qiao Ruida wants to develop an [-]W fast charging protocol and fast charging chips. There are almost no finished chips for reference, so she can only lead the chip research and development team to start from scratch.

In the next few days, Qiao Ruida concentrated on chip research and development, leaving early and returning late, working extremely diligently.At the same time, Ruida Technology launched a new round of recruitment plan. Recruitment information for hundreds of positions and thousands of employees suddenly appeared on major online recruitment platforms, attracting the attention of countless job seekers. Every day Thousands of talents submit their resumes through online channels.Liu Jiayu organized a team to screen resumes and interview candidates.

Recruitment teams from Reda Technology Company have also appeared in major talent markets in the Beijing area.The threshold for recruitment this time is relatively low. Whether they are experts and professors, veterans with certain work experience, fresh graduates, or newcomers who have just entered the workplace, they are all included in the recruitment category.Even if you are a wage earner who has come out to work after graduating from high school, you can still find a grassroots job with good pay at Reda Technology.

As the recruitment work continues, the manpower of the R&D department has gradually become sufficient. The number of people has rapidly expanded from more than 100 to more than 500, and it is still increasing. There is a new atmosphere of strong troops.Qiao Ruida divided these R&D personnel into several groups according to their interests and areas of expertise, and then split the smartphone R&D plan and assigned them to each group in the form of tasks.With sufficient talent and a large amount of capital investment, smartphone research and development has finally entered the fast lane. Small results can be produced in three or two days, and big tasks can be completed in ten and a half months.

The chip R&D team led by Qiao Ruida personally came up with the first version of the fast charging chip design in just one week.After getting the chip design submitted by his subordinates, Qiao Ruida conducted a tape-out test in the dimensional space.As a result, the chip produced has basically realized the fast charging function, but the conversion efficiency is too low. The chip will heat up like crazy as soon as it is powered on. If a heat sink is not installed on the chip, it will burn out in a few minutes.Such a chip has too many defects and cannot be used in mobile phones at all.

After further research and analysis, Qiao Ruida found dozens of design flaws in the first version of the fast-charging chip design, and had no choice but to send it back and have the chip R&D team overhaul it.

During this time, Du Qingqing was busy looking at houses again, and occasionally asked Liu Jiayu or Li Xiaoshuang to help her with reference.On this day, after get off work, Qiao Ruida drove Du Qingqing back to campus. During the drive, the two talked about buying a house.Du Qingqing said: "This morning, the agent took me to see a courtyard house. The location is very good and the area is large. But the price is too expensive, more than [-] million. When I heard the price, I was attracted on the spot. Scared away."

As soon as she heard that there were courtyard houses for sale, Qiao Ruida immediately became interested. You must know that courtyard houses in the capital are scarce resources. They are small in quantity, high in price, and appreciate in value quickly. It is quite difficult to come across them. "Tell me quickly, where is the courtyard you are looking at? How far into the courtyard is it? Can it be renovated?"

"That courtyard house is in Shijia Hutong. It has three courtyards. It covers an area of ​​more than 600 square meters and has more than 50 rooms. It is quite large and has a good layout, but the price is too expensive. As for whether I can get the renovation permit, I I’m not too sure. Why, Ruida, you really want to buy a courtyard house. That’s more than [-] million, which is really an exaggeration.”

At an intersection ahead, the red light was on. Qiao Ruida stepped on the brakes and stopped the Mercedes-Benz. While waiting for the red light, she turned to Du Qingqing and said: "That is a courtyard house covering an area of ​​more than 600 square meters. Shijia Hutong, known as the best housing in the school district, is not too expensive to sell for more than [-] million. Ruida Technology Company still has several billions of idle funds in its account. It is worried about where to invest. It buys a courtyard house for fun. Not bad."
