In terms of technology, Shen Li rarely obeys anyone, but he still admires Mr. Xu's technical ability, in his opinion, it is a waste to be the boss with Mr. Xu's ability, if he can concentrate on technology, maybe ten or twenty years later, he will be an Einstein!

Seeing the incomprehension on the drawings, Shen Li immediately asked, "Mr. Xu, what is the purpose of the thin iron in this place!" ”

Seeing that Shen Li didn't understand the role of the motherboard's protective layer on the drawing, Xu Hongwen pointed to the exploded view on the drawing and said with a smile: "Mr. Shen, I made this design to protect the parts on the motherboard, you can understand that it is the last protective layer of the motherboard!"

As a mobile communication tool, mobile phones are carried around after being carried in their hands, which also causes a lot of uncertainty to the use of mobile phones.

Because we can't prevent customers from using accidents in the use of mobile phones, so we must take these situations into account when developing them, after all, the value of a mobile phone is not a question, our mobile phones can not let customers fall once or twice on the scrap, we have to do more work in terms of drop resistance and waterproofing, I don't say to do King Kong is not a bad mobile phone, but it must be made into the most durable mobile phone in the industry! ”

After hearing the boss's request, the technicians present were dumbfounded, and said that Mr. Xu's requirements are too high, compared to some of the predecessors in the industry, their accumulation of technology is certainly not as good as those companies, if it is not so simple to make the most durable mobile phone, for example, there is no precedent in the international waterproof electronic products (of course, some military products must be excluded, that kind of waterproof is only sealed and waterproof), and mobile phone products cannot be completely sealed!

Drop prevention is also a big problem, the mobile phone is not heavy but not light, from a certain height or a certain strength to the ground, it will definitely cause a greater impact on the shell of the mobile phone, the parts on the motherboard, the screen, this external force damage is uncontrollable, because falling from different angles will cause different damage, so it is almost impossible to do the anti-fall task!

Shen Li saw that his subordinates on the left and right kept giving him a look, in fact, at this time he was also secretly bitter in his heart, when he worked at Motorola before, he didn't have a drop-proof and waterproof requirement, although he was willing to try it after listening to Mr. Xu's request, but Shen Li was still unwilling to accept it before he had a definite solution!

If you have difficulty mentioning it in person, don't agree to the boss but it will be really embarrassing to not be able to do it then, Shen Li immediately said: "Mr. Xu, what you said about waterproof and anti-drop requires our R&D department to be willing to try, and you also know that it will be difficult to meet your requirements, I am afraid it will be difficult for us to come up with a solution for a while!" ”

Xu Hongwen smiled, these requirements he put forward are actually a bit harsh, waterproof and anti-drop has always been a big problem for mobile phone products, in later generations in addition to Nokia in this side to do the best, other companies have also done some work in this area, but the effect is good and bad, in the future for a long time Nokia is almost synonymous with the god machine, Nokia mobile phone fell into eight petals after picking it up and using it correctly, after soaking in water, you can continue to use it, Compared to other brands of the same era, Nokia's durability is unquestionable!

It is Nokia's requirements for excellence in quality, which verifies the story of quality achievement brand with iron-like facts, and Nokia has built confidence in their products in the hearts of consumers by virtue of excellent quality, and Lu quality has also become the cornerstone of Nokia's world's first sales throne!

However, success is also Xiao He, too much pursuit of quality requirements of Nokia in the direction of the development of the big screen cautious, and blind confidence in the Symbian system, when the Android system came out after the behemoth is unwilling to make changes collapsed, the fall of the later generation of Nokia can be said to be too conservative in the company's decision-making, it can also be said that they are too insistent on quality!

Of course, now Xu Hongwen has not yet faced a dilemma, mobile phones in this era still belong to the rich people's things, and there is no zài mobile phone system dispute, so Xu Hongwen feels that now is the best period to establish a brand with quality, although he is now demanding, but it is not without solutions, for some Xu Hongwen specifically borrowed from a lot of successful technologies of Nokia in later generations, sometimes the technical aspect is like a layer of paper, and it feels difficult when there is no solution, But once you find the right direction, it doesn't feel so difficult!

Xu Hongwen said several solutions on the spot, for example, in terms of waterproofing, Xu Hongwen specially drew a short circuit protection circuit, wrote the circuit formula and explained the working principle of his circuit, the technical personnel present are talents in this area, before just did not study towards the aspect, now after seeing the circuit and the formula can not help but suddenly realize!

This circuit was something they had never seen before, and at this time an engineer asked curiously: "Mr. Xu, we have never seen a short-circuit protection circuit, did you invent this circuit?" ”

Xu Hongwen, who heard this, didn't think about being modest, and cheekily took this circuit as his own, and said with a smile: "Yes, I have been thinking about these problems for the past two days, so I have explored this circuit by myself, and I don't know if it is useful, I will try to use it later, and see if it works!" ”

Another technician patted his ass and said: "It must be okay, it is very perfect from the perspective of the operating principle and circuit formula of the circuit!" ”

Xu Hongwen smiled and accepted all those sycophants, what he wanted was this effect, Xu Hongwen not only wanted to let the people in other departments of the company worship him, but also let the people in the technical department admire him, Xu Hongwen continued with this calculation in his heart: "We can also work on the sealing of the shell, of course, I also know that the shell is impossible to be completely waterproof, but as long as we do the best in the tightness of the shell, it can also greatly reduce the danger of water seeping into the mobile phone!"

It is certainly not enough to rely on the short circuit protection circuit for waterproofing on the motherboard, we can seal the important parts on the motherboard, so that even if the water enters the motherboard, the parts and water can be well isolated, so as to protect the mobile phone from being burned out to the greatest extent!

And the sealing not only has the function of waterproofing, when the mobile phone is dropped, some parts on the motherboard will form a greater impact force, and the sealing also has the use of reducing the damage to the parts under the impact force, of course, this and the motherboard protective layer just now are the last protection!

The most important thing is the design of the mobile phone case, because the moment the mobile phone falls to the ground, the force first acts on the shell, if this force is not dispersed, it will be transmitted to the motherboard, so it will be easy to cause damage to the parts on the motherboard, so when we straighten the shell, we should consider the appearance at the same time, but also pay attention to the application of mechanics, as much as possible to let the mobile phone shell absorb this impact! ”
