Chapter 214 A Small Trial and Continuous Good News
At the beginning, Liang Xiaojun, Asia Pacific manager of HP's ICT testing division, received a call from the head of Flextronics' purchasing department, saying that a small company that provides after-sales service for PCB bare board testing equipment was going to visit him. He was a little surprised. Although PCB testing and PCB testing are only one word apart, the technical difficulty of the two industries is very different.
The test software for a model of PCB bare board circuit board needs to write in the parameters of all components. If there are integrated circuits and CPUs on the circuit board, it will be more complicated. It takes a professional programmer several days or even a week to write it.
After writing the program, making the test fixture, and putting it in the debug debugging and error correction link of the production line, it is even more complicated...
What is there to talk about with a small company that provides after-sales service for PCB bare board testing equipment?
It was really for the face of Flextronics, a big customer, that Liang Xiaojun reluctantly agreed to meet.
In the conference room, after Liang Xiaojun got Li Xiaofan's business card, he looked at the address of the company and found that it didn't look like a small company. It seemed to be quite powerful. He asked, "Mr. Li, do you have something to talk to me about?"
Li Xiaofan said directly, "Well, Manager Liang, I want to be your business partner for the ict test equipment hp3070..."
Liang Xiaojun smiled, "Mr. Li, do you know our hp3070 test equipment? Have you seen it when you went to the Flextronics factory?"
"Well, not only have I seen it, I can also use hp..."
After hearing this, Liang Xiaojun was a little curious, "Mr. Li, where did you study before?"
Li Xiaofan lied, "I studied in an electronics factory in the mainland and here at the Flextronics factory for a while..."
"Oh, now we have several hp3070 machines in the test laboratory next to our conference room. Now our engineers are debugging and correcting a model of test fixture. Are you interested in going to see it together?"
Liang Xiaojun thought that the young man in front of him was bragging to attract business, and wanted to scare him off.
"Okay!"
In the test lab, two engineers were debugging a complex large-size computer motherboard test fixture. One of them, Lin, was from HP, and the other, Huang, was from a HP partner company, helping customers like Flextronics to make test fixtures and write test software programs.
Since yesterday afternoon, the two have been busy for almost a whole day, and there are still dozens of false defects displayed on the computer screen, and each time the test is done, the false defects are different.
When Liang Xiaojun took Li Xiaofan in, Lin and Huang were sweating profusely.
"Mr. Li, you just said you can debug, why don't you try it?" Liang Xiaojun said to Li Xiaofan:
"Okay, please give me the circuit diagram, I'll try it..."
Seeing this, Lin and Huang gave up their seats, and they could just take a break from their busy schedule.
Li Xiaofan went up to the hp3070 machine, skillfully operated the keyboard, entered the unix system inside, typed out the unix command, and checked the test reports just now.
As the saying goes: An expert can tell the quality of a product with just one move.
Li Xiaofan's few simple operations stunned Liang Xiaojun, Lin Gong, Huang Gong and the other three: Oh, a veteran! Looking at the proficiency of operating Unix commands, it would be impossible to be so proficient without three to five years of experience...
HP3070 uses the Unix operating system. People who have not received professional training and systematic learning simply cannot understand it, let alone operate it.
The Unix operating system is a powerful multi-user, multi-tasking operating system that supports multiple processor architectures. According to the classification of operating systems, it belongs to a time-sharing operating system. It was first successfully developed by Ken Thompson and Dennis Ritchie at Bell Labs under AT&T in 1969.
The predecessor of the Unix system is the 1ICS system. In 1965, Bell Labs joined a plan jointly organized by General Electric and MIT to establish a multi-user, multi-tasking, multi-level MULTICS operating system. Bell Labs participated in the development of this operating system, but because the development speed was too slow, Bell Labs decided to withdraw from the plan in 1969. Later, Ken Thompson and Dennis Ritchie, engineers at Bell Labs, successfully developed the Unix system.
Then, Li Xiaofan tested it manually, opened the test fixture, and studied it carefully.
Li Xiaofan asked, "Manager Liang, do you have super glue and extra plastic blocks here?"
"Yes! Engineer Lin, please give it to Director Li..."
Li Xiaofan cut a few small pieces of plastic blocks with a knife and glued them to the three support positions under the test fixture with super glue.
He asked again, "Do you have HSS high-flow probes and GKS spring probes from Ingun, Germany?"
Engineer Lin replied, "Yes, there are some in the drawer!"
After opening the drawer, Li Xiaofan replaced about thirty probes.
Then press the start button to restart the test.
After pressing the button, there was a "puff" sound, and the air pressure valve locked the test fixture on the HP3070 machine. Then, the machine began to vacuum extract the air in the test fixture.
After the air was extracted, the upper and lower parts of the test fixture separated.
