Coquettish Rebirth

"Mr. Jia, where do you... come from?" Guo Taiming obviously didn't know what Jia Hongjian was talking about. After all, this matter was just the result of a test in MS company. "After testing on our side, the solder joints of the display power modules you made for us are unstable, and after hundreds of hours of use, there will be false soldering! You Hon Hai is a world-renowned foundry, and you can have this kind of problem. ? You took money from others to play with me, right?" Jia Hongjian was so angry that he was not polite at all.

When Guo Taiming heard this, he was shocked at the time, "There is such a thing? Are you sure it is a power module? So, where are you now, Mr. Jia, I will send... No, I will fly over to see it myself!" Lao Guo arrived at this time Also surprised!He concentrates on making Hon Hai Precision as an OEM, and doesn't even do any of his own brands, in order to allow various upstream manufacturers to cooperate with them with confidence!To be honest, if they produce their own brand, the cost is of course low, and it is not impossible to do it, but this will form a competitive relationship with the upstream, so of course the upstream will not come to purchase their stuff!I won't let them come to OEM!For example, if HP asked Hon Hai to manufacture their server products, it didn't take long for Hon Hai to produce a similar product. If HP was fed up, it would let Hon Hai do the OEM!

It can be said that Guo Taiming chose to avoid the brand at all in order to avoid risks as little as possible, and continued to march directly into the risk-free foundry.However, if we continue to advance, we will have very high requirements for the craftsmanship and product quality of the foundry. After all, if the product is not well made, it will make the family popular, and the result will be no money to make!Hearing Jia Hongjian complaining about such things, how could he not be anxious?He is optimistic that ms company may become the second Dell or something in the future!If you exaggerate the brand of ms company, in addition to the uneasy conscience, it will also reduce the number of OEM orders in the future!After all, ms has become bigger, so the order should go to Hon Hai?

"Mr. Jia, don't worry about this matter. If I go to see it, it will indeed prove to be a problem on our production line. Don't worry, I will cover all your company's losses! We will eat this batch of goods ourselves! I will give it to you again. You start to do it, do you think it’s okay? If it’s okay, I’m going to fly over to find you right now!” This Guo Taiming is really an old ghost who has been in the mall for decades, and the solution he gave at this time is absolutely satisfactory. !

Hearing this, although Jia Hongjian was still a little worried that even if he handled it like this, it would delay the launch time, but there is obviously no better solution at present, and at the same time, he is already interesting enough.He also lost a lot of anger. "I'm in Boston now, how about this? I'll send my special plane to pick you up. You can arrive in Dawan within about 10 hours, and then fly over within 10 hours!" Jia Hongjian thought for a while, Simply do not save money.Directly use the fastest way!After all, the sooner this is resolved, the better! [

Hearing what Jia Hongjian said, Guo Taiming was stunned for a moment, "10 hours?" It's not that he has never done a private jet, and the business jets these days are basically subsonic!Normally, a supersonic plane can fly for more than ten hours. How can this subsonic plane fly for 10 hours?But no matter what, now is not the time to discuss this matter. Guo Taiming thought about it and said, "Okay, then I will bring a team of about 20 people over there. I will help you directly to see what is wrong with the product!" Well, okay!"

After hanging up the phone here, Guo Taiming looked unhappy, and he didn't know why this kind of problem happened!It is not the first time for them to help OEM LCD screen assembly!For example, there are quite a few laptops in the world that are manufactured by them. These laptops also use LCD screens!Although the size is not as big as the 20-inch screen of ms company, the overall craftsmanship is not too bad, so there shouldn't be such mistakes!Could it be because it was the first time to assemble a large-screen LCD display.And it's still independent.So there is something wrong with the machine setup of the production line?With decades of experience, Guo Taiming probably locked the wave soldering machine on the production line at that time.But I can't be sure about this until I see the product.While he hastily greeted the people from top to bottom of the company to prepare to go to the United States urgently together, he arranged for the people left behind in the company in Dawan to quickly take some samples of the products in the MS company's inventory and check them out!

After a few hours of hard work, nothing wrong with the stock sample was found, and everything was fine. Guo Taiming and his team of 22 people were about to pull out their hair!The 22-person team includes the company's technical talents, the technical directors, backbone technicians, and even the heads of the production workshops, production lines, and key workers who cooperate with the MS company's project.These [-] people can be said to have covered all aspects of the all-in-one product of ms company!Any quality problem in product details, as long as the team analyzes it, it should be able to be found directly on the spot!

They couldn't find out the results here, but on the other side, Jia Hongjian's special plane urgently reported the flight plan at Los Angeles Airport, then hurriedly checked and refueled, and finally took off in an emergency three hours later to Dawan.Then after another 5 hours, we arrived at Daiwan.When the plane landed, Guo Taiming and others held a continuous meeting in the company to analyze the problem of the product. After knowing the plane arrived, a group of people rushed to the airport by car, and then sat in this strange silver-white plane. All the way to America!

After the plane arrived in the United States, Guo Taiming, who had just got off the plane, saw Jia Hongjian, and before Jia Hongjian could speak, he said directly, "Mr. Jia, we have basically researched this problem theoretically. , don't worry, this matter is covered by Hon Hai, and we are responsible for all losses, now you can take us to see the real thing, okay?"

Hey!This old Guo is quite powerful!When Jia Hongjian heard this, his anger basically dissipated, "Okay, get in the car and leave quickly!" After getting in the car, he began to be curious about how Lao Guo and the others found the quality problem. It took nearly a month of 24-hour start-up experiments before they discovered these problems. This Lao Guo and the others can find out after a test in the warehouse of Daiwan? "Boss Guo, how did you discover the problem?"

"Hehe, Boss Jia, it's like this..." Guo Taiming began to explain their conjectures to Jia Hongjian - it turned out that these things happened because of the design problems of the all-in-one machine!Jia Hongjian and the others chose FL cold-cathode fluorescent tubes, which, to put it bluntly, are very thin fluorescent tubes.Although this kind of fluorescent tube generates less heat than incandescent lamps, it still has some heat.It is acceptable to make a 20-inch and [-]-inch notebook screen, but if it is made into a [-]-inch large screen, the overall heat generation will be much higher!Moreover, this is an all-in-one machine!There is also a computer motherboard and other things installed behind the monitor!The overall temperature is even higher!

Even, in order to adjust the brightness of this liquid crystal display, Jia Hongjian and his colleagues at Huaxia Hi-Tech adopted a simple method used by LG - to change the current through a variable resistor to change the brightness of the FL backlight fluorescent lamp.Household fluorescent lamps cannot change the brightness, but incandescent lamps can, why?It is because incandescent lamps, especially desk lamps, are equipped with variable resistors.That is, through different resistances, the current through the filament is different to cause different brightness.Also, this technique can actually be used in fluorescent lighting as well.But when such a variable resistor itself is controlling the current, it will also generate heat!

Hon Hai Precision has never made such a high-calorie combination before!You must know that even if it is a notebook computer, because these days, pus and graphics cards have low heat generation.And the display is still separated from the motherboard, so the heat is not so terrible.But if these things are integrated into a display, the heat will be a bit... so what.Although this all-in-one machine itself is designed with ventilation and heat dissipation, but the all-in-one machine can't increase the horsepower, large air volume and large-size fan to dissipate heat?At most, only a small fan can be used, and the result of a small fan is high noise, and high noise on an all-in-one machine is obviously intolerable to Jia Hongjian.So in the end, the overall design of this machine is still a bit of a heat sink, which means that the heat will accumulate!Where does this heat accumulate?It just happened to be stuck in the corner of the circuit board of the display power supply component!

etc!It sounds like this is Jia Hongjian's problem?Could it be that Jia Hongjian was wrong to blame others when he got angry before?Of course not!Because Jia Hongjian and MS company designed such a compact thing for the first time.They are inexperienced, and it is normal except for minor mistakes. Similarly, for an old Jianghu like Hon Hai, it is the first time to manufacture this kind of integrated thing, and they have no experience, so they have not found any problems!And Hon Hai has a little more responsibility. In order to complete this order as soon as possible, they chose a purely streamlined wave soldering machine to complete it!

And what is a wave soldering machine?To put it bluntly, this wave soldering machine is actually such a thing: for industrial welding of components and circuit boards.Manual welding cannot be used.So automatic welding.In this automatic soldering, a kind of wave soldering was born, that is, the solder such as solder is directly melted.The jet is then pumped into a wave-like crest.Then use a machine to "lick" the heated pb printed circuit board and the components mounted on it over the solder wave crest with almost zero distance. Something like that, it will hang on the melted solder, and then it will be soldered directly.Afterwards, just cut out a little bit of excess solder or something, and the board is ok!

However, it is impossible for all parts on a circuit board to require the same degree of soldering!Some components may require a slightly deeper soldering, that is, a deeper hole for the solder to enter around the pins, and some require a shallower one.And this kind of wave soldering machine is obviously impossible to be so precise - large-scale industrial production is naturally a mass production of ordinary quality!And this kind of wave soldering machine that relies on the solder wave to lick the pb board is even more one-size-fits-all for all pins!

The consequence of such a one-size-fits-all is that some components may not be soldered enough, and some components may be soldered too much!Therefore, it has always been a headache for the circuit boards coming off the wave soldering machine, and the solder joints of the components to fail later.The so-called late failure, which means that due to long-term use, and then continuous heating and oxidation, some components that were originally soldered shallowly are soldered!

Then, Hon Hai and the others have gone through technical and process improvements before, so that this wave soldering product can actually last for a long time. For example, if it takes four or five hours a day, it lasts for three years, which is about 5000 hours. , is no problem.After 5000 hours, there is a relatively large possibility of problems with this product, and at this time the product is almost out of warranty, and the manufacturer is eager to break it quickly at this time!Only when it is broken can it be repaired to make money, and it is easy to sell new products!After all, industrial electronic products, which are supplied to consumers, cannot be all guys with a combat power of 100. In fact, they are basically gadgets with a combat power of less than 5!No matter how conscientious a business is, it is impossible to make a product without any defects, because a product without defects is the rhythm of starving your company to death!If consumers don't upgrade, how can manufacturers survive?Is it possible to make a product for a lifetime, and then stop selling it after selling it?

Therefore, even the most demanding manufacturers turn a blind eye to this aspect. After all, electronic products are not works of art, and they cannot be perfect! (To be continued.
