Return to Singapore 1995

When listening to Manager Zheng Zaisheng's explanation and translation, some bosses nodded in praise, while others whispered to each other in private, expressing doubt.

"Really?"

"Is it really that amazing?"

Some bosses privately expressed dissatisfaction, especially the two bosses from the model factories of Osaka and Kyoto Group.

Because they felt that the data Zheng Zaisheng said seemed a bit too exaggerated...

At this time, the yellow warning light of the second-generation test machine No. 2 operated by Li Xiaofan lit up, and the word "FAIL" appeared continuously, which means that the tested circuit board failed.

If failures appear continuously, one possibility is that the tested circuit board PCB really has defects, and another possibility is that there are "false defects" in the machine test, and the circuit board PCB itself has no problem. The real reason may be, for example, the test fixture has problems, the probe is broken, and dirt is covered on the probe...

In the electrical test workshop, the most important factor affecting the test efficiency is how to quickly deal with "false defects" and quickly find the problem.

If the problem is not found, the machine stops there, time passes by, and what is lost is efficiency and money! The problem becomes a bottleneck.

Now machine No. 2 tests a HP motherboard PCB with more than 2,000 test points.

Li Xiaofan took a circuit board that was judged to be unqualified, and the machine test print result was: 567 points and 675 points were open. After taking a look at the circuit diagram of the circuit board, he quickly measured it with a circuit meter. The two points were connected intact and the resistance was zero. This means that the test result is a "false defect".

He immediately stopped the machine, and after pressing the OPEN button, the machine automatically opened, and the upper and lower test fixtures inside were covered with more than 2,000 densely packed probes. It was so dense that it gave people a kind of intensive phobia.

According to the circuit diagram, he glanced at the probe area where the two test points 567 and 675 were located. There were several probes with heads that were obviously shorter than the probes next to them. According to his experience, these probes were on the verge of fatigue. He quickly replaced all six probes in that area with new ones, blew the surface of the fixture probes with an air gun, and pressed the "RUN" button again.

The machine restarted the test, the "PASS" green light came on, and the circuit boards passed the test smoothly.

Li Xiaofan's maintenance actions were completed in one go, and the shutdown time and time did not exceed two minutes.

To make matters worse, Li Xiaofan had just finished working on machine No. 2, and the other second-generation test machine No. 1 began to light up with a yellow warning light.

This batch of circuit boards was the Western Digital WD hard drive PCB that stumped the engineer Haruma Haneda from the Tokyo TAIYO Electric Headquarters last time.

There were more test points with errors in the automatically printed test report.

Li Xiaofan quickly took out a magnifying glass from his pocket and observed the circuit board that was judged to be defective. It was the same old problem, caused by a slight displacement of the screen printing during the circuit board manufacturing process. The circuit board itself was fine.

After he paused the machine, he turned off two of the cameras. Haruma Haneda learned from his experience last time and reprogrammed the machine interface to add the function of turning off any of the cameras.

Then Li Xiaofan replaced the single-tip probes of several problematic test points with German hard crown probes, and slightly adjusted the aligment parameters of the test fixture to keep it consistent with the displacement of the screen printing.

After the No. 1 machine restarted the test, the "PASS" green light came on, and the circuit boards passed the test again.

This time, Li Xiaofan's maintenance action was still done in one go, and the machine was stopped for no more than two minutes.

"すごいですね!"

"Excellent!"

Meaning: Wow, it's amazing! Excellent!

Several big guys on the side exclaimed.

Then, someone started clapping. After watching Li Xiaofan's performance, the bigwigs from the branches of Westwood Electronics Group around the world applauded.

The few bigwigs who had expressed doubts in private just now fell silent.

The leading group president Koizumi asked MD Inabe Saburo and Manager Zheng Zaisheng in English: "Is this operator a local of yours in Singapore?"

"No, this young man is an operator we recruited from mainland China last year!" Zheng Zaisheng replied.

"Oh, that's right, it's excellent!"

President Koizumi said to Saburo Inabe and Manager Zheng Zaisheng: "I have seen some reports and data recently. Our group's factories in Osaka and Kyoto introduced the second-generation TAIYO electrical test machines at the same time as your Singapore factory. At present, the overall test efficiency of the electrical test workshop of your Singapore factory has exceeded that of the model factories in Osaka and Kyoto. Seeing is believing today. You must keep working hard!"

After hearing this, Saburo Inabe laughed heartily: "Thank you for the encouragement, President. We will continue to work hard!"

In the history of Ximu Electronics Group, the management efficiency of factories in Japan has always been the highest.

In the previous life, Li Xiaofan remembered that the same test machine could test 1,000 pieces per hour in the headquarters factory of Ximu Electronics Group in Japan, and the factory in Singapore was discounted to 800 pieces per hour, and only 600 pieces per hour when it was set up in the mainland.

This is often a problem of management and culture...

After the VIP visitors left, FORMAN Chen Zhenwei patted Li Xiaofan on the shoulder and praised: "Afan, you can do it. You really make our workshop and Singapore factory proud!"

Today, the workshop director Lin Qianxue took leave because of a foot injury and did not come to work.

Li Xiaofan pretended to be bitter and asked: "Brother Wei, can you give me a partner? I will be exhausted if I operate two machines for a long time!"

"I originally wanted to give you an assistant to operate the two machines together, so that you can relax, and let that employee learn from you, but the Officer specifically instructed yesterday that it would not be possible in the next few days. Wait until she returns from her sick leave!"

Hearing this, Li Xiaofan was speechless. Did Lin Qianxue deliberately let him perform in front of the group's big bosses and visitors today?

…

Before leaving get off work, Chen Zhenwei found Li Xiaofan: "Afan, why don't you work overtime recently? Your basic salary is so low, is this basic salary enough for you to spend?"

"Brother Wei, it's not that I don't want to work overtime, but I recently signed up for ITE's on-the-job electronic engineering certificate course in my spare time, so I want to concentrate on further studies during this period..."

"Well, if you have any academic problems, you can talk to me..."

"Great, thank you Brother Wei!"

After leaving get off work on time, Li Xiaofan came to the Orchid Village Market for dinner.

Today he ordered a serving of Singapore's Fujian fried noodles.

Fujian shrimp noodles are called Hokkein Mee in English. Yellow noodles and rice noodles are paired with seafood, and shrimp, squid, eggs, pork, bean sprouts and other ingredients are added and repeatedly stir-fried, and then stewed with pork bone and shrimp soup. The essence lies in the soup. The shrimp heads and shells are sautéed, and then simmered over high heat for half an hour, and crispy pork lard is added to make the layers richer. When eating, you can also add chili sauce to mix the noodles, which is very fragrant and delicious.

The fried Fujian shrimp noodles of Zheng's Fried Noodles in Orchid Village are cooked at a good temperature, and are springy when eaten. The noodles absorb the freshness of the soup and are fragrant.

Li Xiaofan likes to eat the fried noodles from this shop with local special sambal chili sauce and squeeze a little lime to enhance the flavor. It is delicious!

When eating happily, someone suddenly shouted from behind: "Afan, oh old man, I've been looking for you for a few days!"
