I've done whatever I want

Chapter 82 Half Engineer

Process engineer Su Tianyi said that DOE was a boring thing. Not only did this not persuade Xin Tong to quit, but it aroused his great interest.

All his life, he likes to do things that others don't want to do, and walks the road that others don't want to walk.What other people think is more boring, he finds it more interesting.

Leaving the bonding workshop, DOE has been hovering in the young man's mind, which is like a goshawk soaring over his vast grassland.

Judging from the tone of Su Tianyi's words, it was difficult to learn more about DOE. The young man had an idea. He thought of Sun Xiaolong, one of the four heavenly kings. If Sun Xiaolong didn't know DOE, Ming Yueguang closed beta test. It is very rare for people in the factory to know about this tool.

In the afternoon, Sun Xiaolong came over: "Xin Gong, if you encounter difficulties at work, please communicate with me in time!"

As one of the Four Heavenly Kings, his focus is mainly on the client. How is the development risk of new projects controlled?Has the root cause of the problem been found in customer complaint handling?Client review escorts and things like that.

If the client is satisfied, the boss is also satisfied, and there is hope for promotion and fortune.

"Sun Tianwang, I just went around the production line, and today's yield rate is normal!" Xin Tong replied.

"You should pay more attention to the MES system. If there is a Hold Lot (referring to defective products that are prohibited from flowing) exceptions, they must be handled in time! If it cannot be handled, please notify me." Sun Xiaolong said.

Xin Tong nodded.

"Is there anything else you don't understand?" Sun Xiaolong asked.

Xin Tong pondered for a moment and asked curiously: "King Sun, do you know DOE?"

"Of course I know that DOE (Design of Experiments) is a statistical analysis tool. In terms of product design, process optimization and quality improvement, it can help us find the optimal design scheme and the best combination of process parameters. The engineer at most is half an engineer!" Sun Xiaolong said with a smile.

"Half an engineer?" Xin Tong was very surprised.

From this point of view, I am at best half an engineer!I really didn't expect this DOE to be very important to an engineer.

"Xin Tong, let me tell you about the history of DOE, so that you know its importance. The germ of this tool can be traced back to the ancient Greek philosopher Aristotle more than 2000 years ago. In his rich practice In the process, he summed up the single-factor method, which means only changing one factor in each experiment."

"However, the founder of DOE that is recognized today is the British statistician Fisher. During the breeding process in the 20s, Fisher demonstrated variance analysis for the first time and applied it to experimental design. And the one who popularized and carried forward experimental design in the industry is none other than Dr. Genichi Taguchi from Japan.”

Regarding the origin of DOE, Sun Xiaolong is very familiar with it.

Xin Tong nodded while listening. There is no doubt that DOE can be regarded as the crystallization of the great wisdom of mankind.

"Xin Tong, at Mingyueguang Packaging and Testing Factory, when we launch a new product, we will do DOE analysis on the main process parameters!" Sun Xiaolong continued to introduce.

"Really?" Xin Tong was full of curiosity.

"Our wafer cutting process parameters, our bonding process parameters, and our plastic sealing process process parameters, these parameters are especially important for product quality, and we must do experimental design and analysis!" Sun Xiaolong is very familiar with packaging and testing control.

So DOE is by your side!

Be sure to master this tool well!You can't just be half an engineer in your life!

"Xin Gong, I believe that future equipment will have deep learning capabilities. Then, the equipment will do DOE analysis and self-optimize process parameters according to the differences between product batches!"

A great god is a great god, and his thinking is very advanced!
After Sun Xiaolong finished speaking and walked away, the young man opened the Minitab software in the computer, checked every menu in it curiously, and unexpectedly found that there was a DOE item in it.

He originally thought that this software only supports SPC analysis, but he did not expect that its function is very powerful.

The young man rubbed his eyes with his hands and stared at the computer screen with wide eyes, unbelievable!
So as long as you input the data in the software, you can do DOE analysis, and the software will prompt you what is the optimal experimental plan!

Xin Tong was full of curiosity and began to fiddle with the software in the computer.

After he proudly entered a set of data, after calculation and analysis, the optimal plan was indeed prompted!
God!It's so amazing!
At this moment, he really wanted to shout.

Turning his head, Xin Tong found that everyone in the office was working hard. He immediately covered his mouth with his hand, for fear that the creepy scream would slip out of control.

At this moment, it is not difficult for the young man to understand the dilemma Su Tianyi is facing. The Minitab software is not installed in his computer, so it is really not easy for him to do DOE analysis.

After an in-depth understanding of the techniques involved in Six Sigma, Xin Tong felt that the DOE (Design of Experiments) technique was the best choice for improving product yield.

If the DOE method is used to optimize the process, manufacturing is taken into consideration during process design, and the SPC method is used for statistical analysis and variation monitoring during the manufacturing process, then the product yield will be very stable.

After mastering the SPC exercises proficiently, Xin Tong began to aim at the experimental design DOE.

Back to the dormitory after get off work, I heard that Xin Tong is going to Xitang tomorrow to play. Xiang Gong, who enjoys a five-day and eight-hour work system, is very happy: "Very good, let's go forward together!"

"It's really fun for you to be engineers, but we as operators have to fight overtime pay, and can't go anywhere on weekends!" Zhu Tianli spread his hands, feeling infinitely emotional.

I’m so envious and jealous!Too much hatred!
"Damn Fatty, when I asked you to study, you skipped classes everywhere, and now you lament that it's useless!" Xiang Gong rolled his eyes at Fatty.

"Hmph, did you go to heaven after reading a few more sentences?" The fat man returned Xiang Gong with a big roll of his eyes.

Like every dormitory, Building 8, 519 is always full of fuss and neurosis.

The next day was Saturday. Early in the morning, the door of the dormitory was banged.

"Who is it!" The fat man rolled off the bed.

No reply!

Zhu Tianli rubbed his eyes with his chubby hands, walked to the door, and opened the door with a "squeak".

"Damn ghost, you've knocked on the door for a long time and there's no response?" Xiang Gong gave the fat man a look.

"You are the ghost, I slept soundly, and I was woken up by you!" The fat man yawned.

"If you don't get up, you will be late, do you want overtime pay?" Xiang Gong's voice raised an octave.

Xin Tong saw that it was Xiang Gong, who had agreed to go to Xitang yesterday, so he must have come to call him, turned over and climbed off the bed.

The fat man's eyes were very sharp. Seeing that Xin Tong got out of bed, he slipped into the bathroom like a dexterous mouse and didn't come out for a long time.

"Fatty man, get out of here!" Xiang Gong lost his temper.

"I'm sorry, I caught a cold last night and my stomach was so cold, I need to stay a little longer!" The fat man replied.

Xiang Gong shook his head, turned around and said to Xin Tong, "Hurry up and pack your things, we'll go over there early for lunch!"

"Xiang Gong, do you know how to get to Xitang?" Xin Tong nodded and couldn't help asking after putting on his clothes.

Today is an engineer for five days and eight hours. The young man can calm down a bit. There is no need for him to grab the toilet with the fat man as soon as he gets up.

"Xin Gong, don't worry, follow me, and I will never lose you!" Xiang Gong patted his chest and said.

"Okay! You are familiar with that side, I am relieved to go with you!" Xin Tong nodded.

The two were chatting, only to hear a loud noise coming from the toilet.

After a while, the fat man came out from inside: "It's so cool!"

"Fatty, has the toilet been flushed? Why is there still a strong smell in the air?" Xiang Gong frowned and shouted with his sharp nose.

"Xiang Gong, I've already flushed two buckets of water, what else do you want from me?" The fat man argued with his hands on his hips.

　It's the weekend again, as the old saying goes, happy weekend!Thank you all for your votes!
