I've done whatever I want

Chapter 58
After leaving the office of FOL engineering department, Xin Tong walked into the working area of ​​the bonding workshop in high spirits!
There is no doubt that this is his main battlefield. On the basketball court, the young man has achieved unparalleled success. Now he needs to make great strides in the production field and create greater glories.

He appeared in the bonding workshop like a hero, and soon attracted everyone's attention.

"Our beloved MVP Xin Tong is here!"

"Although he is wearing static clothes, it can't cover up his good figure at all. He is so handsome today!"

"Everyone, stop fighting. Today he is the food in my girl's bowl! If you want to fight, just wait until tomorrow!"

Words of praise floated faintly in the workshop, which reached the young man's ears from time to time, which made him feel proud.

Since his rebirth, he has not been so glorious for a long time.

Xin Tong first walked around Area F. In this area, the bonding machines were generally in good condition after being shut down for maintenance on Christmas Eve.

The four female operators have been working very hard recently. After all, they ate barbecue and received careful guidance from the factory flower He Silian. They always have to pay something. There is no free lunch in the world.

During this period, the young man used his spare time to carefully study "the SIX SIGMA WAY", an improvement exercise book comparable to the Nine Yang Magic Skills, and became very interested in the SPC exercises. He heard that the quality department was using SPC analysis. Data, he strolled to the QA (Quality Assurance) inspection area.

A little girl in a pink static suit is busy, her eyes are staring at the microscope, and she is immersed in the thrust test of the gold ball of the chip. This test can evaluate the bonding strength between the gold ball and the chip pad.

The Nordson DAGE 4000 test instrument with metallic luster is specially designed with an ergonomic adjustable system that can help overcome repetitive strain injuries (RSI) of the human body, especially in relation to working height, optical field of view, elbow support and The location of the control unit.

Every time a chip is completed, the latest test data will be displayed on the display screen of the test instrument.

After the little girl finished the gold ball thrust test, she took a deep breath, turned her head, and took out a piece of the frame again, selected 5 of the chips that had been bonded, and hooked the gold wire with the hook of the Dage4000 test instrument. Do a tensile test.

After the experiment, the little girl entered all the collected data into the Minitab software on the computer. This software can automatically generate Xbar-R control charts.

On the control chart, all the data points swing back and forth in the narrow region between plus and minus three sigma.

The young man recognized it at a glance as the control chart mentioned in "the SIX SIGMA WAY". It was with this control chart that Shewhart won the honor of being the father of statistical quality control in the world.

The young man's eyes lit up, and his heart burst into ecstasy. Sure enough, the quality department was doing the SPC analysis of the product. The SPC in the real world, which he had been looking for so hard, was far away and close at hand.

"Are these data qualified?" This is the first time Xin Tong has seen a real SPC control chart. Before studying Six Sigma, he knew nothing about SPC exercises.

"Of course, if the data is unqualified, a red dot alarm will appear in the software, and we will issue a corrective and preventive action report to your technicians, allowing you to analyze the reasons and provide improvement measures!" the little girl inspector said in a long voice.

After all, he was a member of the regulatory department, so the inspector's tone was rather harsh.

"I feel that a lot of data exceeds two sigma!" The young man took a closer look. Although those data points fell within the qualified area, it was obvious that he still felt that the data in the control chart was not perfect.

"As long as it meets the SPC judgment criteria, it is qualified! Take a look at our "SPC Control Procedures", which contains detailed definitions!" This program file was handed over to Xin Tong.

The young man took the bound procedure document, flipped through it, found the "SPC Control Procedure", opened it, and it really defined the judgment criteria in detail.

The following situations are not acceptable:
1) Any point beyond the control limit;
2) 7 consecutive points are all above or below the center line;

3) The line connecting the 6 points rises or falls;
4) Other obviously non-random graphics.

It's amazing!
The young man has been studying the English original for the past few days. He always feels that this exercise is a little abstract. Today, when he saw it in practice for the first time, he couldn't help but sigh that the SPC exercise is really too powerful.

Witnessing the Dage4000 data collection, the use of Minitab software, and the judgment of the Xbar-R control chart, the young man suddenly became enlightened and understood. It was obvious that he had successfully mastered this set of techniques.

To surpass the technician Wu Lei, or to win the duel with the manufacturing engineer Shi Kaitian, tightening the control range of the golden ball push force and the golden wire pull force is the magic weapon to win.

For those devices that exceed the judgment criteria, the young man has already thought about it and must use the fishbone diagram of the seven techniques to make targeted improvements from the 4M1E perspective.

Looking back at the hero list, I now lead the pack with a yield rate of 99.67%.

Wu Lei, who has won three consecutive championships, has achieved the best result in his history with a yield rate of 99.66% after using the seven major techniques.

The battle for the title of Technician Heroes has reached a fever pitch.

It is only a week away from the end of the year. It is expected that it will not be easy for Wu Lei to break through himself. The young man does not want to use SPC exercises to push the yield rate to a new high, which will expose his own strength.

If the SPC method is used to increase the yield data to over 99.7%, then defeating Shi Kaitian will be an easy task.

If you expose your strength too early, you will become a clear card, which is not conducive to winning the final peak duel.

Manufacturing engineer Shi Kaitian seems to be aware of Xin Tong's threat. When he faced Wu Lei last year, he was lucky enough to win with a yield rate of 99.68%. Xin Tong is now very close to this result.

What is this young man doing in the QA inspection area of ​​the quality department?Is he looking for a way to defeat himself?
Full of questions, Shi Kaitian walked towards the chip inspection area.

Seeing his boss walking over quietly, the young man felt a faint murderous aura. The final showdown seemed to be coming ahead of schedule. He smiled faintly and walked away.

"Xiaoyan, what did Xin Tong come here for just now?" Shi Kaitian asked.

"Are you talking about the tall technician? He was just learning about SPC analysis!" the inspector replied.

SPC analysis?Shi Kaitian was stunned.

Is this the practice of Six Sigma?Could it be that Xin Tong has recently been studying the famous and decent martial arts Six Sigma in private?
In his impression, the Six Sigma series of exercises were extremely lethal. Someone once mentioned it to him. Unfortunately, due to his busy work schedule, the exercises were boring and involved a lot of knowledge of mathematical statistics and probability theory. He was discouraged and had been neglecting to practice. .

I really didn't expect Xin Tong to practice Six Sigma. For a person with a high school diploma, practicing the unpredictable Six Sigma is more difficult than reaching the sky. This greatly exceeded the expectations of manufacturing engineer Shi Kaitian.

This new technician is very extraordinary. Through comprehensive maintenance and seven techniques, he has reached the first place on the technician hero list. Now he is secretly practicing Six Sigma skills. If he is unfortunately defeated by this young man in the end, he will die. What a pity!

Fortunately, Xin Tong's current yield data is 99.67%, which is still a certain distance from him, and it is not so easy to surpass him in the short term.

While he was thinking, he saw a group of people walking into the bonding workshop from a distance.

Shi Kaitian's first reaction was that someone came in to visit!
Generally speaking, if a customer comes into the workshop for audit, people from the quality department will notify everyone in advance to do the 5S work in the workshop.

If you haven't received the notification, you must not be a customer, so who is it?The person walking in the front seemed to be hugging each other, very grand.

God!It’s Princess Li Aileen!Why did she come to the workshop to instruct today?When the group of people got closer, Shi Kaitian was shocked.

In the depths of his memory, this was the first time the princess went to the production workshop. What happened this year?
　Princess Mingyueguang left the workshop for the first time, who was she in love with?Family members, let's recommend tickets and collections!
