Mingzhao picked up one of them, brought it close to his eyes, and carefully observed the packaging details of the die and the smoothness of the pins at the interface.
Her movements were natural and fluid, with a neat and graceful beauty.
Zhao Gang and Liu Mei relaxed a little as they checked the incoming materials one by one, confirming that they were within the scope of the reported list.
Then Mingzhao's gaze lingered for a barely perceptible moment at an extremely tiny seam in the package of that transistor, a spot that only a true expert and keen observer could notice.
Randomly, she put down this tube and picked up another tube of the same type.
At the same spot on the second tube, there was an extremely slight, almost imperceptible, difference in color between her fingertips and the surrounding area.
It felt like being lightly touched by some kind of high-precision laser pointer.
What is that? A mark? A defect?
Su Xuan held his breath instantly.
Mingzhao had already put down the second tube, his face still expressionless, as if he hadn't noticed anything.
She then picked up a precision capacitor from the side and examined it carefully in the same way.
But Su Xuan's heart sank.
He knows the quality control of electronic components all too well.
These top-grade military-grade tubes undergo extremely rigorous packaging processes, making such subtle color differences impossible! Moreover, they happen to be from the same model and in the same location!
This is no coincidence!
Su Xuan's back was instantly soaked with cold sweat.
Inside the laboratory, the surface remained calm. The green light of the oscilloscope flickered faintly.
Mingzhao picked up the welding torch and preheated it.
A buzzing sound of electricity rang out.
Her gaze calmly swept over the two seemingly identical high-frequency, high-power transistors in the tray.
One of them, at the seam of the packaging, had a barely perceptible abnormal color difference that, under the green fluorescence of the instrument, resembled a silent, grinning trap.
Su Xuan's back was soaked with cold sweat, and his fingertips trembled slightly as he adjusted the resistors.
He dared not look at the two high-frequency tubes in the tray, much less at Mingzhao's calm and composed profile.
Chen Songnian's words, "playing with fire," lingered in my mind like a venomous snake. This trap was too insidious!
Conventional methods simply cannot detect that subtle packaging anomaly! When the entire system is under high-power load during integrated testing, the stress concentration point inside this tube will inevitably fail. At best, it will burn out the core module; at worst, it will trigger a chain reaction that will cause the entire project to collapse!
At that point, all the blame will be pinned precisely on Mingzhao, the person in charge whose identity is questionable! He'll be doomed!
"Is there a problem with the materials?" Ming Zhao's cold and calm voice suddenly rang out, like ice water being poured over someone's head.
"Wh...what?"
Su Xuan was startled.
"I don't know..." His expression was hesitant as he pointed to the spot he had just noticed that was not quite right.
"Would you like to take another look around here?"
Mingzhao looked in the direction he was pointing.
Zhao Gang and Liu Mei, who were standing nearby, immediately became alert, their sharp eyes fixed on the parts in their hands.
"What happened?"
Mingzhao stared at the areas of color difference without saying a word.
Su Xuan glanced at Ming Zhao.
Something's not right here.
Liu Mei and Zhao Gang took the tube and examined it from left to right.
Zhao Gang said, "I'll take it to someone for a checkup."
Su Xuan nodded.
Mingzhao remained calm. He took out another tube and continued the experiment.
Su Xuan glanced at the tube, and only after confirming that there were no problems did he feel relieved enough to go about his other tasks.
He glanced at Mingzhao discreetly.
Liu Mei's gaze followed Ming Zhao the whole time.
I observed her movements.
How did you discover the problem?
She was asking about Mingzhao.
Mingzhao shook his head: "It was discovered by Engineer Su."
Su Xuan was called out, so he had no choice but to nod.
"Yes, it's me."
Liu Mei didn't believe such a thing; it was Mingzhao who had just spoken out.
Even if Su Gong's expression showed some doubt or something, Ming Zhao shouldn't have noticed it.
However, Liu Mei did not ask any further questions, but silently noted Mingzhao's unusual behavior in her mind.
Zhao Gang immediately contacted Zhang Mingyuan, presented the evidence, and demanded that Zhang Mingyuan release the test results immediately.
Zhang Mingyuan was still a little confused as he looked at the pipe.
"Impossible! The materials our research institute provided to Comrade Mingzhao couldn't possibly be wrong!"
Zhang Mingyuan could not believe that such a thing could happen within his jurisdiction.
Zhao Gang's face was cold and stern: "Is it possible or not? Dean Zhang requests your cooperation in the investigation."
Zhang Mingyuan's hands were trembling slightly when he took the transistor. After carefully observing the anomaly, he finally felt relieved.
"I'm going to get the lab tests done."
Zhang Mingyuan changed into a lab coat, entered a laboratory, took out the contents of the transistor, put them in a glass bottle, and conducted analysis and research.
Finally, Zhang Mingyuan walked out of the laboratory with a heavy expression.
Yes, that's right. That transistor was actually coated with a highly dangerous antimagnetic powder crystal.
Zhang Mingyuan is now focusing all his attention on controlling himself.
So much so that they had no idea that his face was as dark as if it were about to rain.
Or perhaps an even bigger storm is brewing.
What did you discover?
Zhao Gang stopped Zhang Mingyuan.
Zhang Mingyuan put the report he was compiling behind him.
"This is a matter for our research institute; I can handle it myself."
After saying that, he tried to avoid Zhao Gang.
But Zhao Gang stopped him.
"Dean Zhang, please cooperate with my work."
