Chapter 9 A bigger surprise

Along pointed at the back of Li Xiaofan who was wiping the test machine with everyone in the crowd:

"Report to the Officer, it was Afan who ran! Two people in our group took sick leave last night. Afan was borrowed by me from A Biao in the post-processing group..."

"Li Xiaofan?"

Looking at the data on the report, Lin Qianxue couldn't believe her eyes. It turned out that it was this young mainlander from the post-processing group who ran away!

"Really? Last night, during a late night shift on machine No. 8, a total of 7,265 circuit boards of nine models were run, almost reaching the highest record in the history of this machine! Along, tell me the truth, did Li Xiaofan really run alone?"

She opened her mouth wide, speechless with surprise. A mainlander who had basically not been trained in the test workshop actually ran out of the historical record! It was simply unimaginable for her!

After hearing the conversation between workshop director Lin Qianxue and team leader Along, people in the entire test workshop knew that Li Xiaofan had actually run out of the highest record of machine No. 8 last night.

Last night, due to the lack of two people, everyone was busy taking care of their own machines and ignored Li Xiaofan who was helping in the corner.

"Oh my God, 7265 pieces, even I, a five-year employee, have never run out of this number!"

"Oh my God, did Xiaofan really run out of it alone?"

"It should be true. I saw him working there alone last night. At first, I thought there was only one model, and the molds were all debugged by the team leader A Long. It turned out that he ran a full nine models last night! Oh my God, what a genius!"

Everyone was talking about it.

"Officer, it's true, I debugged the mold of the first model, and Afan did it all by himself. No one helped! If you don't believe it, ask everyone!" A Long vowed to Lin Qianxue.

"Yes, yes, Officer, we can also testify!" Several workers on the side also chimed in.

Aaron continued to say to Lin Qianxue: "Officer, I have a request. I want to apply to transfer Li Xiaofan from the second shift's post-processing team to our third shift's testing team. Our team really needs talents like him!"

"Aaron, let's put this matter aside for now!"

After Lin Qianxue finished speaking, she shouted to Li Xiaofan who was busy wiping the machine in the corner: "Li Xiaofan, come here!"

"Officer, do you have something to ask me?" Li Xiaofan turned around and said.

Lin Qianxue pointed to the two boxes of circuit boards that the post-processing team had just delivered and said: "Li Xiaofan, use machine No. 8 now to change this batch of newly delivered circuit boards for me to test!"

"Okay!"

Li Xiaofan put down the rag in his hand, came over to take out the flow list on the two boxes of circuit boards, and saw that they were American Seagate hard disk drive control circuit boards: SEAGATE11026.

In the 1990s, Seagate's hard disk business was in full swing, and Ximu Electronics Factory received sales orders. That era was the golden age for the beautiful saleswomen of the Ximu Electronics Factory. They spent most of their time sitting in the office and answering calls, receiving emails, and doing after-sales service. Although they were busy, they did not feel any pressure at all.

However, the test workshop was most afraid of seeing this type of circuit board: because this multi-layer hard disk control circuit board was not only small in size and thin, but also had a strange and irregular shape. The circuit board was covered with dense test points. There were more than 400 test points on one side alone. The probes on the mold were very thin and easy to break. And because the probes were very thin, if they were covered with a little dust, they would not be able to detect the solder joint, which could easily cause false alarms.

The workers in the test workshop usually walked around when they saw this type of circuit board being delivered, pretending not to see it, and usually threw it to the team leader A Long to deal with it.

Li Xiaofan had actually run this type of circuit board last night, so he was familiar with the operation now.

This time he didn't even need a flow sheet, and went directly to the mold warehouse next door to get the upper and lower test molds of SEAGATE11026.

After quickly adjusting the spacing of the loading and unloading tracks, click "UNLOCK" on machine No. 8 to unlock the air pressure switch and remove the original old mold.

After skillfully pushing the upper and lower test molds of SEAGATE11026, four small stainless steel columns for proofreading are placed on the four corners of the lower mold.

After gently pressing and completing the alignment of the mold, he took a sample circuit board and tested the pressure.

Under the light, Li Xiaofan used a magnifying glass to check whether the indentation of the probe was accurate.

Every time the mold is replaced, there will be a slight shift, and the circuit board also has errors during the printing process. There are differences in each batch of the same model, so this debugging process is very important.

Debugging is the core link of electrical testing!

Under the magnifying glass, Li Xiaofan found that the insulating paint of this batch of circuit boards was slightly shifted to the left, and the indentation of some probes was shown to be pressed on the insulating paint, which would form a false alarm.

He gently adjusted the upper mold slightly to the right and tested the pressure again. The probe indentation was almost in the center of the test solder joint.

After replacing five or six probes that had lost their elasticity, he powered on the power and tested it manually. The machine displayed "PASS"!

Finally, he put the circuit board into the sending box of the machine, pressed the start switch, and the No. 8 machine started running smoothly!

Lin Qianxue watched with her own eyes that the SEAGATE11026 circuit boards on machine No. 8 passed the test quickly and smoothly, and finally believed what A Long said was true.

She looked at the back of the busy mainland youth in front of her, feeling a little incredible.

"Li Xiaofan, how did you learn to test?"

"When I delivered boards to the test workshop before, sometimes everyone was busy, so they asked me to help a few times, and slowly I learned it..." Li Xiaofan replied with a smile.

In his previous life, Li Xiaofan was transferred from the post-processing group to the test workshop two years after he arrived at the Ximu Electronics Factory. The situation was indeed as he said. There were several smokers from West Malaysia in the late-night test workshop. They were particularly addicted to smoking. When they were addicted to smoking in the middle of the night, they often asked Li Xiaofan, who came to deliver boards, to help take care of the machine so that they could sneak out to smoke. For this reason, they often trained Li Xiaofan on some operating knowledge of the test machine.

After a few times, the smart and studious Li Xiaofan learned to operate the test machine, and the efficiency of the machine he ran when he helped was much higher than that of the Malaysian workers in the test workshop.

Gold always shines. In his previous life, he was finally appreciated by Lin Qianxue two years later and was transferred to the test workshop. Later, he was sent to PSB Academy for on-the-job training by Lin Qianxue and promoted to the leader of the test team of the third shift...

The facts are in front of us, which speaks louder than words. Li Xiaofan's answer made Lin Qianxue look at him with new eyes: Oh, this young man from the mainland is so attentive and hardworking! When she came to the workshop for inspection the night before yesterday, she was surprised to find that he could communicate with Uncle Suba in English.

Unexpectedly, this morning, Li Xiaofan gave her a bigger surprise!
