I've done whatever I want

Chapter 165 Chip's Bathtub Curve

Returning to his hometown in Yuezhou, the sight of ruined walls and ruins in front of him made people feel rather desolate, but he didn't feel cold.

You can make a lot of money by manufacturing chips in Shanghai, and the poverty and misery you see before you is temporary.

For Xin Tong, who earns over [-] yuan a month, there is nothing worse than this situation. When the situation is at its worst, it means that it will get better in the near future, and everything is full of hope.

From the moment he stepped into his hometown, rebuilding the old house was already in his plan!
Although the value of houses in Shanghai is appreciating very quickly, and the return on buying a house in Shanghai is extremely high, Xin Tong can save a few more months to collect the down payment, enough to meet the threshold of buying a house, but his hometown is the root, and the living conditions of his parents are need to improve!
Limited funds need to be invested first in the reconstruction of old houses.

So will Xin Tong still buy a house in Shanghai? The answer is yes!
On the hottest days in real estate, getting in your car anytime is the right thing to do.

On that day, the enthusiastic Xin Yang left Jiang Hua and Xin Ba behind, and the richest and most powerful person in the village came to visit him, and he felt his face was radiant.

Usually he walks with his head down, but today he held his head high and walked lightly. Xin Yang sharpened the kitchen knife, turned around to the corner, and took the bloated capon out of the coop. It was slaughtered, and it was thrown on the ground with a "pop".

The rooster, who was lucky enough to escape the disaster, sang triumphantly beside him.

That day, under Xin Tong's fierce offensive, Jiang Hua and Xin Ba were both drunk when the city gate fell!

After drinking the wine, Xin Tong felt a sense of emptiness!
When he didn't go home, he always longed to return to his hometown and his elderly parents. But when he really returned to his hometown, Xin Tong still felt that something was missing in his heart. Yes, his My heart still remains in Mingyueguang Integrated Circuit Factory.

For a workaholic who aspires to make cores, he feels uncomfortable all over without working for a day.

Before leaving, the MPC5200 chip had already been put into the burn-in box. In order to catch up with the progress of the Motorola project, the laboratory arranged for the experimenters to work overtime during the National Day to do the high-temperature working life test HTOL.

Speaking of the reliability test of HTOL, the conditions are quite harsh. The experimenter bakes the chip in a furnace at a high temperature of 150 degrees Celsius, and then energizes the test board to make the chip work. It is just like a person working with a hoe under the scorching sun. It is easy. Death suddenly.

Sun Wukong developed his piercing eyes in Taishang Laojun's Bagua furnace. After the chip is smelted in the aging furnace, it will wear the aura of AEC-Q100 certification, win the respect of the market, and earn a lot of RMB.

Before returning home, Xin Tong went to the reading room to borrow some reliability technical materials, such as the JEDEC standard and the AEC-Q100 Failure Mechanism based stress test qualification for integrated circuits standard. In his spare time, he would sit down and study carefully.

Wang Dongmei saw her son studying hard on his business knowledge and was very happy in her heart.

She just looked at her son from a distance, afraid that she would disturb him if she got close.

Xin Yang wanted to pour a glass of water for his son, but she grabbed him by the corner of his clothes: "Old ghost, please don't bother your son, please!"

Wang Dongmei said while giving the man a fierce look.

In the early morning of the next day, Xin Tong took time to go to Yuezhou City alone.

He always felt that there was a strong pulling force in Yuezhou City, pulling him there. The minibus bumped on the rural road for more than an hour before he arrived in the city.

This city, which exudes the light of profound history, has many attractions. There are places to visit everywhere. Some people like to rent a boat and go around Yuezhou City on the moat. Some people like to go to Shen Garden to watch Yue Opera. Some people like to climb Kuaiji Mountain. Some people like to go there. Visit Sanwei Bookstore.

Xin Tong likes to climb Fushan Mountain in the center of the city. This mountain was called Wolong Mountain in ancient times. It has lush forests and many places of interest. Wen Zhong, who made great contributions to the victory of the King of Yue against the King of Wu, is buried on this mountain. His tomb is halfway up the mountain. , quietly overlooking the thousand-year-old city of Yuezhou.

The most prominent building on Wolong Mountain is a majestic building called Yuewang Terrace, and the mountains and forests exude an imperial atmosphere.

Under the mottled city wall, art lovers gathered together and sang the Yue Opera "King Gou Jian of Yue".

"I am waiting with you. I will taste the gall of hardship, lie down and stab the enemy, gather together again, secretly launch an army, a million-strong army, overwhelming the mountains and seas, destroy the Wu Palace, avenge the humiliation, and plant the flag high on the Gusu Tower."

Gou Jian lay down on the firewood and tasted his courage, and three thousand Yue Jia could devour Wu. For such a majestic event, the libretto of Yue Opera is clear and graceful, soft yet strong, and full of character.

Whenever he hears the Yue opera "King Gou Jian of Yue", Xin Tong feels his blood boiling all over. Xi Shi flashes before his eyes, the genre flashes, a peerless sword that represents the pinnacle of Wuyue's bronze sword-making technology flashes, and the period 1000 years ago flashes Fiery history.

Who said that Yuezhou is just a place where masters can be born?

There is no shortage of Qiu Jin, the heroine of Jianhu, in Yuezhou, and there is no shortage of Gou Jian, the martial arts master!

Facing the refreshing river breeze blowing from the Qiantang River, standing on the majestic Yuewang Platform, Xin Tong couldn't help but think of the packaging and testing project of the MPC5200 chip that he led. He is now doing reliability verification, according to the HTOL 1000-hour experiment Calculating the time, it turned out to be almost December.

Why!Two months, what a long wait!

But compared to the mother's ten-month pregnancy, what is the two-month test time?

If the result of the test is Pass after two months, all the waiting is worthwhile. If the result of the test is Fail after two months, everything has to start all over again, then it will be a sad reminder.

What's even more frustrating is that I don't know whether Motorola will give Mingyueguang a chance to start again!
If you miss this project, you will miss out on the international giant Motorola, and you will miss out on a lot of RMB banknotes.

For Mingyueguang, this project is a starting point for Motorola. If successful, there will be many opportunities for cooperation in the future.

A gust of autumn wind blew over, and Xin Tong suddenly remembered the bathtub curve of product failure rates.

It's a great idea to associate the reliability of a product with a basin for bathing.

The life of the chip does follow this great law.

If the chip is improperly designed, if the materials are defective, and the packaging process is poorly selected, the defects of the chip will be quickly exposed in the aging furnace.

Once the chip has been tempered in the early failure period, the failure rate will drop to a low level. At this time, the chip is like a young and middle-aged man, and ordinary diseases cannot invade it. The chip failure is caused by accidental factors. The accidental failure period This is the main working period of the chip!

After the accidental failure period, it is the wear and tear period, just like a person entering his twilight years, unable to withstand the intrusion of disease, and there is a risk of failure at any time.

As long as the reliability test of the chip has passed the early failure period, it can basically be concluded that the life of the chip is not a big problem.

If only we could know the early stages of chip failure!Xin Tong thought to himself.
