I've done whatever I want

Chapter 172 Seventy-seven forty-nine days
Early that morning, Xin Tong took the bus from the train station in Huzhou. After getting off the bus, he bought two steamed buns at a roadside stall and ordered a bottle of mineral water. Headed towards Mingyueguang Integrated Circuit Factory.

After entering the factory, before going to the office to drink Anji white tea, I went straight to the reliability laboratory.

During the seven-day National Day holiday, in his hometown in Yuezhou, he was thinking about the reliability test in the furnace all the time.

Counting on fingers, the MPC5200 chip completed seven days of experimental verification in a high-temperature aging furnace, and no bad news came out, proving that these chips have broken the 168-hour curse of life and death.

According to the theory of chip design madman Yuan Chengxu who died young, these chips are robust.

There is no doubt that the MPC5200 chip has entered the second stage of the bathtub curve, the occasional failure period.

Entering the workshop, he took off his shirt and put on a white electrostatic suit. He looked in front of the mirror in the dressing room. Fortunately, he had no dark circles after taking the night bus all night yesterday.

Passing through the air shower, the workshop with a constant temperature of 25 degrees brings a touch of coolness.

The laboratory is at the other end of the workshop, and he has to walk through the entire production workshop.

After not taking a few steps, he stopped, and the operators there were all whispering about Han Huhu's departure.

Jiang Hua was right, Han Leng dropped a thermobaric bomb in the bright moonlight!

However, he was concerned about the reliability test, and he had no time to think about it too much. He shook his head and continued to walk forward.

When I arrived at the reliability laboratory, I looked up and saw the CNAS logo posted on the door of the laboratory, which was very conspicuous.

CNAS is the English abbreviation of China National Accreditation Service for Conformity Assessment, and the Chinese name is China National Accreditation Committee for Conformity Assessment.

Being able to obtain CNAS certification shows that the management level and technical capabilities of the laboratory have reached the international advanced level. The reliability test report issued by the laboratory is authoritative and can be recognized by the national and regional accreditation bodies that signed the mutual recognition agreement.

Bright Moonlight's reliability laboratory is built in strict accordance with CNAS standards, and successfully passed the CNAS certification.

As far as the domestic integrated circuit packaging and testing industry is concerned, there are no more than three laboratories that have obtained CNAS certification, and Mingyueguang is one of them.

The hard-core strength has won the respect of the technology giant Motorola. They agreed to Ming Yueguang's request without hesitation and put the MPC5200 reliability test at Ming Yueguang.

In this way, the project cycle can be shortened by one or two months, which has a huge impact on the project progress.

Xin Tong was very fond of this laboratory that shortened the project schedule. When he walked into the laboratory, he saw an experimenter recording the temperature and humidity data of the environment.

It's the details that determine success or failure!
Laymen watch the fun, and insiders watch the doorway. The control of the environment is an important part of the 4M1E exercise!
He was slightly surprised. It seemed like a paradise, very quiet, and the experimenters were carrying out their daily work in an orderly manner.

Xin Tong let out a long breath, thank God, the evil wind raging in the production workshop was fortunately not blowing in.

Ming Yueguang's reliability laboratory is under the management of the quality department. The departure of production manager Han Leng did not cause any waves here. It is common for people to come and go in foreign factories.

What's more, the production department and the quality department have always been at odds with each other. Han Laohu left, and the people in the quality department didn't set off firecrackers to celebrate each other, which is enough.

At this time, Ouyang Xiaoxiao, the person in charge of the laboratory, came over and greeted him warmly: "Manager Xin, good morning!"

"Good morning, Xiaoxiao, is the MPC5200 reliability test going well?" Xin Tong asked with concern.

"Everything is very normal, but Manager Xin's martial arts are world-class!"

"A little too much for the prize! It's the horoscope and there's not even a single stroke!"

"Manager Xin, come here! Come here!" Ouyang Xiaoxiao said as he led Xin Tong to an aging stove.

"This is the furnace for our HTOL reliability test. It is a high-end product bought from the United States. The temperature difference of this integrated circuit high-temperature dynamic aging system will not exceed one degree Celsius after heating up!"

"Not bad!"

"Without this advanced reliability equipment, whether this chip can be made in our laboratory will be a question mark! Don't underestimate it, it can be used in analog, digital, and digital-analog hybrid integrated circuits in various packages. , including high-temperature dynamic aging screening and life testing of IC devices such as memory and VLSI." Ouyang Xiaoxiao touched the clean testing machine with his hands wearing electrostatic gloves, full of pride.

"Okay! Very good!" Xin Tong nodded, and through the glass window, he saw the chip being tested inside.

According to JEDEC standards, HTOL needs to test a batch of 77 pieces first.

The full name of the JEDEC standard is Joint Electron Device Engineering Council Soild State Technology Association, which mainly defines the standard of semiconductor hardware. The association consists of 50 committees and subcommittees, and is the leading standard organization of the international microelectronics industry.

77 chips are distributed on 7 test boards. Each test board is connected to an external power supply and the test program is fed externally.

Xin Tong stopped and stared. These chips, which are undergoing aging tests, have been tempered at a junction temperature of 150 degrees and are safe and sound!

He suddenly and inexplicably thought of Sun Wukong, the image of the stone monkey being tortured in Taishang Laojun's Bagua furnace, and how he came out of the Bagua furnace after 49, 1000 days and more than [-] hours. Instead of being burned to ashes, he developed a sharp eye.

Obviously, these chips are monkeys that are immune to flames. Once they jump out of the furnace, they will become famous all over the world!

"How long will the reliability experiment last?" Xin Tong asked after a while.

"According to JEDEC Standard No. 22-A108, it needs to be tested for one thousand hours and 42 days!" Ouyang Xiaoxiao replied.

"Based on this, it's almost 49 days!" Xin Tong said with emotion.

In Chinese traditional concept, Qiqi 49 days is a very special day!

It is said in the myth that it took seven days for God to create man and the world. Every time God felt dissatisfied with the creation, he destroyed it and recreated it. He was only satisfied after a total of seven creations. Therefore, it takes seven to seven days to complete one thing.

"49 is a symbol of catastrophe, 81 is a disaster, catastrophe will make you rich, and difficulty will make you happy! Without going through the test of seven seven 49 days, how can this chip sweep the world?" Ouyang Xiaoxiao said.

"It makes sense! It makes sense!" Xin Tong nodded.

I was hurt by the core in my previous life, and I am determined to build a core in this life, so why not experience disaster?

Looking at the chips in the aging furnace, Xin Tong was full of joy and curiosity: "Xiao Xiao, how do you know that these chips are not Fail?"

"Manager Xin, this is our test current monitor. A single MPC5200 chip consumes a lot of power. By monitoring the current change curve, we can know whether the chip is damaged!" Ouyang Xiaoxiao said, pointing to the test The monitoring instrument next to the machine said.

Xin Tong looked up, and saw a curve displayed on the monitor, like a breeze blowing across the water, causing layers of ripples.
