Chapter 1653 Evidence of Domestic Packaging
Under the "ridicule" and "enthusiastic advice" of the barrage, he decided to carefully disconnect the several cables covering the top of the battery, and then completely remove the entire motherboard module from the body frame.
The tip of the tweezers slid across an area below the memory particles, which was covered with gray thermal grease and a small amount of adhesive for fixing. It looked unremarkable.
But Thor's voice suddenly rose.
"Fuck!"
And with the excitement of discovering a new world:
"So it's hidden here! Playing 'Jenga'! The SOC is underneath the memory, no wonder I can't find it from the front!"
He took a deep breath, picked up the heat gun and a finer, sharper pry bar, and his tone became more serious than ever:
"Brothers, tonight's most hardcore and 'extravagant' moment has arrived! Beneath this 'veil' lies the world's first and currently only 5nm mobile SoC with an integrated 7G baseband—the HiSilicon Kirin 9X! Once this layer of protection is removed, the chip is completely scrapped, with no possibility of repair. But to satisfy your curiosity and to uncover the truth, we're going all out today!"
He turned up the heat of the heat gun slightly and applied extremely precise and localized heat to the edge of the gray adhesive covering the SOC area.
The hot air gun nozzle is only a few centimeters away from the motherboard, and the airflow is concentrated and stable.
After heating for about half a minute, he used the pointed spudger to try to insert it into the tiny gap between the adhesive and the metal heat sink cover below very slowly and gently with the smallest contact area.
The atmosphere in the live broadcast room froze instantly, the number of barrages dropped sharply, and all the viewers held their breath, staring at the tip of the crowbar, waiting for the final exposure of the dirty "core".
Hammer was concentrating so much that beads of sweat appeared on his forehead, and he muttered to himself:
“Be careful… be careful…”
"It feels like it's going in... a little loose..."
“Okay…it’s open!”
With an extremely slight "pop" sound that was almost drowned out by the background noise of the live broadcast room, the silver metal integrated heat sink cover covering the Kirin 9X chip was finally pried off the motherboard completely and intactly.
The inside of the cover was covered in gray thermal conductive material, and underneath it, the "core" that touched countless people's hearts finally revealed its true appearance -
A rectangular green substrate with a dark gray square silicon chip embedded in the central area. The gap between the chip and the substrate and the surface of the chip are covered with a layer of bright silver liquid metal thermal conductive material with a texture like mercury, reflecting a bright luster under the light.
"It's done!"
Hammer heaved a sigh of relief, his voice trembling with a hint of relief, thinking that he almost had a car accident tonight, and decided that he must not be stingy with the money next time. He must buy two at a time and take them apart once to practice before the live broadcast.
But no matter how calm he was, he didn't stop his hands at all. Instead, he quickly used a corner of the dust-free cloth to carefully wipe off the excess liquid metal on the inner surface of the IHS and the edge of the substrate.
"Brothers, the chip in a cell phone's SoC is too small, only slightly larger than most people's fingernails. It's impossible to see the circuit clearly. Even if you want to see key information, you need a microscope!"
He first put on a monocular magnifying glass, then aimed the high-magnification mobile phone external macro lens that had been prepared in advance at the chip area, and adjusted the camera's focal length and lighting angle.
The live broadcast was instantly magnified more than ten times, and the surface of the substrate was presented to all viewers:
Surrounding the central die are thousands of tiny round or square pads densely and neatly arranged in gold or silver, like precisely paved micro roads. They are the channels for the chip to interact with the outside world for data and power.
The core is the dark grey square silicon wafer in the center, with a surface as smooth as a mirror, and even extremely subtle manufacturing textures visible under a macro lens.
This is where the "brain" of HiSilicon Kirin 9X lies.
The center of the substrate is not completely smooth either. It is etched with several lines of character information using extremely fine lasers that are difficult to discern with the naked eye but are clearly readable under high magnification.
"Look here!" Hammer used the tip of an ultra-fine anti-static tweezer and, like an archaeologist cleaning cultural relics, extremely gently pushed aside part of the liquid metal thermal conductive material covering the character area on the surface of the Die, carefully revealing the etched words underneath.
He was operating and interpreting in real time, his voice slightly low due to concentration:
"The most prominent one on the top row: HISILCON – Haisen Semiconductor, a chip design company under the Ju Factory. This one is the real one."
Move the tip of the tweezers slightly downwards, pointing to the second line of characters:
“第二行：Hi25A1。按菊厂海思麒麟芯片一贯的命名规律，带集成5G基带的麒麟9X内部代号就是Hi25A1，那我猜如果是标准版不带5G基带的4G版麒麟9X，代号应该是Hi25A0，不过这个日后咱们再说。”
The tweezers continued downward, clearing away more liquid metal, revealing the third and fourth rows of longer character combinations:
"The third line reads: HXDQ-7N-P1. The fourth line reads: Rev. A02. These two lines appear to be internal production batch codes, tape-out version numbers, or design revision identifiers. The alphanumeric combination is complex, and it's difficult for outsiders to decipher its meaning. They're likely internal production line batch codes and design revisions within the foundry."
Some seemingly professional speculations also floated in the barrage, but they were quickly drowned out.
"The most critical part is the last line, which usually contains the batch number of the production information!"
The tweezers pointed to a line of smaller characters near the corner of the edge of the Die. Hammer raised his head and began to interact with the audience:
"According to common rules in the chip industry, the first two digits of the batch number represent the last two digits of the production year, and the next two digits represent the week of production that year. We know that the Kirin 9X chip was released along with the Mate SX series at the end of last year, and for well-known reasons, the chips installed in the phone should have been produced in 2014."
As a veteran digital blogger, Hammer knows that some sensitive topics cannot be brought up openly.
But the audience certainly knew what reason he was referring to.
As expected, a barrage of comments condemning the ban floated across the screen.
However, Hammer didn't respond, but continued to popularize science:
"So, theoretically, the first four digits of this batch number should be 14XX. For example, 1448 means it was produced in the 2014th week of 48..."
While explaining industry practices, he lowered his head again and began to concentrate on identifying the line of characters that still appeared tiny under the macro lens.
Suddenly, he seemed to be paused.
His body was stiff and his breathing seemed to have stopped.
For three or four seconds, the only sounds in the live studio were the low fan noise of the equipment and his heavy breathing. The comments were instantly flooded with question marks:
【? ? ? 】
[Is the game stuck? Is the internet down?]
[What did you see? Tell me quickly! I’m so anxious!]
【Brother Hammer, don’t scare me! 】
A moment later, the anchor suddenly raised his head, his face filled with extreme shock and blank confusion, his voice completely distorted by disbelief:
"Brothers, this batch number is... 1515?!"
The screen image refocused on the center of the substrate, and the first four digits of 1515 were clearly visible.
"Week 15 of this year..." he muttered to himself, "So that's last month, right?"
Amidst a screen full of question marks, a conspicuous, expensive paid comment forced its way across the center of the screen: "Brother Hammer! I can't see the last digits of the batch number! There's liquid metal residue in the lower right corner! Clean it up!"
This comment was like an electric current that struck the stunned Thor.
He suddenly came back to his senses, suppressed the dizziness caused by his pounding heart, and said with a barely perceptible tremor in his voice: "Sorry, brothers, it was a little unexpected."
Then pick up a small piece of brand new dust-free cloth, pinch a corner with tweezers, dip it in a small amount of high-purity isopropyl alcohol, and gently wipe the bright silver liquid metal and fine traces of thermal grease remaining on the edge of the batch number area with almost embroidery precision.
Every time I wipe it, I am very careful, for fear of damaging the fragile marks.
As the stains were completely removed, the complete batch number was revealed without reservation under the macro lens of tens of millions of pixels:
1515-CN19 F3
"what?"
Hammer's right hand holding the tweezers shook violently and uncontrollably as if it was hit by high voltage electricity!
The tip of the tweezers made a crisp "clang" sound and hit the metal heat sink cover that was removed next to it heavily, almost flying out of the hand!
"I...fuck!"
His voice became sharper due to shock:
"Brothers! I think... I discovered something incredible! This Kirin 9X! Its... its production information..."
According to industry standards, if the chip is manufactured by TSMC, it should start with TW, basically TW01-01.
Because the "CN" in the batch number only represents the Chinese mainland.
in other words……
Thor realized that he seemed to have accidentally discovered something extraordinary.
He suddenly raised his head, wanting to tell the audience in the live broadcast room this shocking news.
However, the live broadcast screen that appeared in front of him was only pitch black.
In the lower right corner of the streaming software, an emotionless white prompt box popped up:
