Enjoy!

A treat indeed!

"It's really pleasing to watch this kid draw PCB diagrams!"

Not only Jiang Ning himself was immersed in enjoyment, but the buddy next to him also felt this way, the smooth operation, the hearty wiring, and the fascination of this buddy was fascinated. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As a result, Jiang Ning's wiring was completed, and this buddy realized that he was on the machine to investigate, and his work was not completed, so he hurriedly turned around and drew his own PCB diagram.

Twenty minutes!

The total time it took for Zhang Min to calculate Jiang Ning was only twenty minutes from the ornament to the completion of the wiring!

You know, a skilled worker who has worked for about two years basically takes nearly an hour to draw this PCB diagram, but Jiang Ning, who has just graduated for only half a year, only took one-third of the time to complete the PCB diagram of the power module, which has to be said to be a miracle!

At this time, there were already four applicants, including Jiang Ning, who had completed the drawing work, but the others took about half an hour longer than Jiang Ning.

After a while, the time for the one-hour on-board inspection arrived, and Director Zhang stopped a few people who continued to draw PCB diagrams, and within the specified time, several of them did not complete their work and were eliminated first.

Next, the remaining six completed PCB drawings are checked.

If you can't just finish the drawing, who knows if you have a problem with the drawing, so you have to check to confirm the accuracy of your PCB drawing.

Speed and accuracy are the two most important indicators of this on-board inspection, and both are indispensable!

The inspection work is naturally completed by the supervisor and the director, Gan Song is responsible for the personal inspection, and Zhang Min helps to check and fill in the gaps in the back.

Both of them are experts in this way, and the inspection is naturally very fast, and in a blink of an eye, the PCB drawings of the five people in front of them have all been checked.

It's a little funny, five PCB diagrams, four of them, more or less have some errors in it, and the only PCB diagram without errors is sitting next to Jiang Ning, the guy who forgot his work when he watched his wiring before, this guy hurriedly completed his work in the remaining ten minutes or so, and there were no mistakes, and he was also a talent.

After the PCB drawings of the first five people were checked, Gan Song and Zhang Min came to Jiang Ning, which was the last PCB drawing.

At this time, whether it was the candidates who were eliminated before or those who wanted to stay in the company, none of them left, they all gathered around Jiang Ning's seat, watching the PCB diagram drawn by Jiang Ning, everyone wanted to see how this young boy who dared to argue with Director Gan drew it.

There are many people, so naturally it is crowded, and everyone is surrounded here, so that the person concerned, Jiang Ning, is squeezed out......

There was no way, Jiang Ning had to roll his eyes helplessly, then pulled over a chair and sat behind everyone waiting for the test results.

According to Jataman, there is still a lot of time left, and the last PCB drawing must be checked 'well'.

"Small, it's strange that the drawing is so fast, and there are no mistakes, and if you catch a mistake in a while, you will be beaten back to your original shape!"

With this thought, Gan Song sat in Jiang Ning's position, clicked the mouse, and first skillfully opened the automatic detection program of the PADS software (the software for drawing PCB diagrams) and began to self-check.

This self-test program is a set of programs that come with the PADS and can automatically detect simple errors such as 'line spacing' or 'electrical short circuit'.

With the rapid running of the progress bar, everyone around them was staring at the screen without breathing, and they seemed to think that this kid, who had only graduated for half a year, must have made many mistakes in the PCB diagram completed in less than half an hour.

However, the final test result was disappointing to them, not to mention the 'error', not even some innocuous little 'warning'!

This couldn't help but make everyone gasp, it's too perverted, how did he do it?

Gansong, who inspected it himself, couldn't help frowning slightly, but after a while, he turned off the self-test program, and then operated the mouse and keyboard to start the manual inspection.

For the inspection of PCB drawings, manual inspection is the most important link, which will start from the layout, wiring, rationality and other aspects of the PCB for a comprehensive inspection.

At this moment, Gan Song checked extremely carefully, even more carefully than when he was doing the most important projects in the company, the reason was naturally that he wanted to find errors or loopholes in this PCB diagram, and then he could deal with Jiang Ning.

In addition to Jataman, the many candidates crowded here also widened their eyes, carefully examining the PCB diagram, hoping to pick out one or two mistakes from it, so that their minds were balanced.

Otherwise, a kid who has only graduated for half a year has no mistakes in the PCB diagram drawn in less than half an hour, and they have been working for two or three years, and it took nearly an hour, and the news of the error spreads, where will their faces go?

However, to the disappointment of these people, the eyes of Jatamançon and the applicants were a little sour, and they did not find a single error on this PCB drawing!

From the most central power management chip, to the surrounding diodes and transistors, from capacitors and resistors, to inductor beads, etc., I completely checked the changes, and there were more than a dozen pairs of eyes staring at it for a moment, and I didn't find a single error!

"Ahem, I'll look at that transistor again, I didn't pay attention to it just now. ”

"By the way, I have to take a good look at the grounding pin of the power management chip. ”

"Well, I didn't seem to have looked at this line very seriously. ”

……

After checking it completely, he didn't find the slightest mistake, and the jatamansong who was sitting there had long since lost the posture he had before, he blushed his face, found some excuses, and rechecked it by himself.

As time passed, one of Jataman's faces turned a little green......

As a director of the hardware department, he was very embarrassed to bet with a candidate who had just graduated for half a year, and now, he couldn't check the slightest mistake in the other party's PCB drawing, and he was about to lose, and he lost in front of his favorite director Zhang Min and so many applicants, he was naturally unwilling.

"How can it be right, it can't be, it can't be right......" Gansong roared in his heart.

The red-eyed Jamanson searched the PCB diagram over and over again, and at one point, his eyes suddenly lit up, and then he burst out laughing, and the laughter was full of the pleasure of discovering a new continent.

"Hahaha...... Found it, finally found it, Jiang Ning, take a look for yourself, you are missing an important information on this PCB drawing, as a sketchboard engineer, this is an unforgivable mistake!"
