Chapter 213 Night Back Beauty and HP3070

Li Xiaofan hurried over to help Daisha up and asked, "How are you, are you okay?"

"It's okay, it hurts a little!" Daisha pointed to her left ankle.

Under the moonlight, the instep of her left foot was slightly swollen.

Li Xiaofan knelt down and observed, "Maybe your ankle ligament is sprained. Can you still walk? No, why don't I send you to the hospital for emergency treatment?"

Daisha waved her hand and said: "No need to go to the hospital, it's not that serious! It just hurts a little when walking..."

Li Xiaofan checked that it was still about ten minutes' walk from here to the exit of the Night Zoo, and there were no tour buses passing by.

"How about I carry you to the exit?" Li Xiaofan suggested.

"Can you bear it? It's a long way..." Daisha took Li Xiaofan's arm and hesitated.

Li Xiaofan worriedly said: "If you walk for ten more minutes, I'm afraid your feet will become more and more swollen."

"Well, thank you for the hard work, Afan!"

Li Xiaofan knelt down behind him and said to Daisha: "Come up!"

"Then I'll get on it, be careful, I'm very heavy..."

Daisha, who is 1.72 meters tall, weighs about 110 kilograms. Riding on the back of Li Xiaofan, Li Xiaofan felt really heavy!

But Daisha's body is very elastic, soft, full and warm. Her body smells very good with body fragrance and light perfume, and there is also a slight smell of sweat.

It was the presence of the blond beauty that gave Li Xiaofan the motivation to grit his teeth and carry Daisha to the entrance of the zoo.

After putting down Daisha, he was already covered in sweat, and his back and chest were almost soaked.

"Afan, I'm so sorry. Thank you for your hard work. Wipe your sweat!" Daisha found a pack of napkins from her bag and handed it to Li Xiaofan.

Li Xiaofan wiped his sweat and asked, "Are your feet okay? Do you want to go to the hospital for emergency treatment?"

Daisha said: "It shouldn't be a big problem. There is medicine for injuries in my dormitory. You can go to the school infirmary tomorrow. In fact, for people like us who study dance, such minor injuries are commonplace..."

Judging from Daisha's appearance, it should be fine. Then, Li Xiaofan stopped a taxi and took Daisha to the school dormitory before going home.

It was already past one in the morning when he returned to the terraced house dormitory. After taking a shower and changing into clean clothes, as soon as he lay down, his cell phone started ringing.

Due to the time difference, there were several business consultation calls from all corners of the world in Europe and the United States. They all called after seeing the Yifan Company advertisement on the homepage of Yahoo.

After answering the phone, Li Xiaofan thought that this was really not an option. He would suffer a nervous breakdown from these midnight phone calls.

So, I picked up my cell phone and called Jerry Yang directly in Silicon Valley, USA, and asked him to help remove his mobile phone number from the Yifan company's website and just leave his email address.

After making the call, he simply turned off the phone and finally had a peaceful sleep.

After waking up the next day, Li Xiaofan's work plan for himself was to visit HP and Teradyne, the two largest ICT online test system equipment manufacturers in the world at the time.

The full name of ict in English is incircuittest, and in Chinese it is called online testing. It mainly refers to the testing process of the circuit board PCBA after all electronic devices have been assembled.

With the rapid development of the electronics industry, circuit board styles are becoming more and more complex, from single layer to double layer, and from double layer to multi-layer.

There are more and more electronic components and integrated circuit modules on the circuit board PCBA, which are becoming more and more sophisticated. There are often hundreds or even thousands of components on it, such as computer motherboards or server motherboards. Densely packed with various electronic components and integrated circuits.

In the production process of circuit board component mounting and plug-in production, whether it is a manual or automatic production line, it can be said that it is difficult to avoid missing parts, dropped parts, skipped parts, wrong parts, cold welding, misalignment or defective parts.

Moreover, during the production process, it is impossible to observe with the naked eye whether these electronic components and integrated circuits are damaged or whether their parameters have changed. Professional ict online testing equipment is required.

The circuit board PCB is called PCBA after SMT mounting and placement of all electronic devices. In the electronics assembly industry, the last PCBA ICT online test is very critical and important.

At that time, HP and Teradyne from the United States were the two largest ICT online test system equipment manufacturers in the world.

The machines of the two test equipment manufacturers have similar principles and consist of three parts: test machine, computer and power box.

The core test machine of the equipment has a test fixture. The test fixture is customized according to the PCBA model of the circuit board and is very complex.

During the test, the air pressure valve locks the test fixture on the machine table. During the test, a vacuum is used to extract the air in the test fixture, so that the test needles on the upper and lower plates of the fixture are inserted into the test points on the board. The control card inside is connected to the computer to control the test.

Its testing function is like using thousands of electricity meters to test PCBA at the same time. It can detect ordinary resistors, capacitors, inductors, transistors, relays, LEDs, amplifiers and other devices, and detect various shortcomings of PCBA circuit boards, such as: Short circuits, open circuits, missing parts, wrong parts, poor parts or poor assembly, etc. can accurately point out the location of defects to ensure p
