I've done whatever I want

Chapter 156 Process Solidification
The MPC5200 sample performance test was successful. The atmosphere at the summary meeting was good. Engineering Director Peter always had a smile on his face. Recently, whether it was the project progress or the MVP-level performance on the basketball court, the results were satisfactory. The foreigner was in a very beautiful mood.

According to the APQP process, the next work is the curing process and trial production of reliability samples.

As for the process solidification, the process group of the engineering department is in charge. Xin Tong is a Six Sigma black belt and has a lot of research on DOE. When the process engineer solidifies the process, he uses DOE analysis to find the best factor combination.

Both the return rate and the test yield are perfect, which means that the sample manufacturing process is impeccable. It seems that the DOE analysis can completely use the parameter data of dummy.

After the summary meeting, as the project manager of Mingyueguang Packaging and Testing Factory, Xin Tong came to the project team office and found Allan. He wanted to discuss the next action items.

"Hi Tong, you did great job!" Seeing Xin Tong walking in, Allan sat at his desk with a friendly smile.

After all, Allan is also the project manager of this project. The success of the project also means his success.

He had received the results of the test data via email. The Mining Moonlight packaging and testing factory had successfully trial-produced a sample of the car-grade chip in one go, which surprised and pleased him.

I really didn't expect that the young man in front of me had two brushes. I had only seen his superb skills before.

"Thanks for your guidance and support in this project!" Xin Tong said with a smile.

When communicating with foreigners, it is extremely necessary to maintain the unique virtue of modesty of the Orientals.

Allan nodded. To be honest, his efforts on this project were very limited. After receiving the email of the test results yesterday, he immediately reported it to Motorola headquarters: "I already sent the mail to HQ and reported the test result yesterday, the feedback is to go ahead!”

Go ahead? This means that the quality department of Motorola headquarters has approved the test results of Mingyueguang. Allan's words made him very excited.

Prototype trial production is a very important Milestone. It seems that the project can continue to move forward.

There is no doubt that this is a great joy!
"You know we still have some Dies on hand, can we move them to build the samples for reliability test now?" Xin Tong asked.

If we move forward with the production of reliability test samples now, the samples will be ready before the National Day, and then it will be delivered to the quality department for experimentation. I can go back to my hometown in Yuezhou to listen to the wind with my parents in this life. The sound of blowing rice waves.

"No, I think you need do DOE analysis!" Allan shook his head stubbornly and said.

This was far beyond Xin Tong's expectation.

At this time, Peter came over, patted Allan on the shoulder, and asked with a surprised look on his face: "Why?"

"Hi Peter, we need to follow up APQP procedure!" Allan said with a shrug.

According to the Motorola project transfer process, each node needs deliverables, and DOE analysis is not done, which means that some nodes are skipped and take risk is required.

If you want to take risk, you need risk assessment.Obviously, skipping this node is not consistent with the Motorola way of doing things.

"You know our testing result 100% pass, and the dummy DOE analysis finished, Cpk is OK!" When the fake film was trial-produced, he had already completed the DOE analysis. Xin Tong explained that if Allan could be convinced, the project time could be saved. .

The success of the project depends on time quality and cost, and time is an important assessment indicator.

"No! No! You must finish the DOE analysis with our Dies!" Allan said, spreading his hands.

It can be seen that he is a very principled person.

"Xin Tong, then arrange a DOE analysis immediately!" Peter turned around and said.

"OK!" Xin Tong nodded.

It is meaningless to fight a war of words with stubborn foreigners, so let's use the data to speak.

He immediately walked out of the project team office, hurried back to the production workshop, and first found Logitech: "Gaogong Luo, please arrange for a process engineer to do DOE analysis!"

"Aren't the test results very good? What else needs to be optimized?" Logitech was puzzled.

"The foreigner is very stubborn, and he must follow the procedure!" Xin Tong was also helpless.

"Okay!" Logitech nodded. The customer is God, and God's requirements must be met, even if they are unreasonable.

He asked the clerk to find the process engineer of the key process. In the conference room, everyone sat down to brainstorm and discussed the DOE analysis factors and levels of the bonding process and the plastic sealing process in depth, and soon a set of verification schemes was released.

This time, the bonding process was performed by Su Tianyi, and Xiao Xianrou Zhu Tao stood aside to guide.

After all, there are process parameters to refer to. Su Gong is just practicing his hands. For a veteran in the bonding process, once the window paper of the low-line arc process is pierced, it is a pediatric matter.

He concentrated and held his breath. After the parameter setting was completed, he watched the bonder squeak and bond. He thought to himself that the low-line arc technology was mediocre, because this technology was defeated by Zhu Tao, and he was too unwilling.

Not only did he lose to Zhu Tao technically, but Xiaoyu, the front desk beauty whom he had a crush on for a long time, was also hooked up by his kid. This period of time was definitely the darkest moment of life.

The samples were completed quickly, and Su Gong then sent them to the quality department for in-depth analysis. One day later, the analysis results came out, which were completely consistent with Dummy's parameters.

Xin Tong collected the test results and compiled them into a DOE analysis report. He emailed Peter and Allan immediately for their confirmation.

"Perfect!" Allan quickly replied to the email.

This set of parameters can guarantee a 100% performance test pass rate, what more can I ask for?

After Allan confirms, it means that the work of process solidification is completed, and now we can arrange the production of samples for reliability test!

According to the project conversion plan, after the production of these reliability samples is completed, they need to be couriered to Motorola's laboratory in the United States for testing.

The reliability test items of automotive-grade chips are implemented in accordance with the AEC-Q100 standard, which are mainly divided into environmental stress test, aging test, ESD and Latch up, and there are many experimental items.

Generally speaking, the aging furnace and temperature and humidity chamber for the reliability test are the same as the production order, and they need to be queued. If Motorola's laboratory cannot arrange it in a short time, the verification will be delayed.

Xin Tong has been to the reliability laboratory of Mingyueguang Packaging and Testing Factory. After understanding, experimental equipment will be available one after another in a few days. Time is money. It would be great if the verification can be completed in Mingyueguang!
Thinking of this, he went to the project team office and found the foreigner Allan: "For my suggestion, I want to do the reliability test in our lab, it will save one month for this project at least!"

"Hi Tong, it is a good idea, but..." Allan, as the project manager sent by Motorola, is also responsible for the progress of this project. He also wants to complete the project as soon as possible so that he can return to the United States to accompany Own wife.

Besides, the food in Huzhou is not to his liking. He eats less, and the weight loss effect is obvious, and his body has lost a lot of weight. If this continues, the wind will blow him away, so why play basketball?
Undoubtedly, after being out for a while, he began to miss the authentic Western food in his hometown.

It would be perfect if this project could be completed before Christmas.

"Hi Allan, our Lab is qualified by CNAS, that means our test result is accepted by ILAC!" Xin Tong could see the wavering of foreigners, and he thought it was time to move out of CNAS certification.

CNAS is the abbreviation of China National Accreditation Service for Conformity Assessment (CNAS). It is a merger and reorganization of the original China National Accreditation Board for Certification Agencies (CNAB) and the China National Accreditation Board for Laboratories (CNAL). Yes, this certification is mutually recognized by the International Laboratory Accreditation Cooperation (ILAC).

Passing CNAS certification means that the laboratory has been accredited by the China National Accreditation Service for Conformity Assessment, has the corresponding technology and testing capabilities, and the test results have a certain degree of authority.

After hearing that the test results of the Yueguang Packaging and Testing Factory laboratory can be recognized by ILAC, Allan nodded: "That is great! I need check with HQ!"

"Perfect!" Xin Tong gave a thumbs up, and Allan agreed. The headquarters really has no reason to refuse a CNAS-qualified laboratory to provide reliability testing services for the project.

　The project is advancing rapidly!
