Decapping an IC Without Acid - Sonic the Hedgehog Edition

- Here is another video of me opening up a plastic encapsulated part, the ADSP-2181BST-115 from Analog Devices. While browsing the Silicon Zoo's website, I came across this part. The website stated that Sonic was found deep inside this chip, so a listing for some parts on Ebay and wanted to see for myself. As you can see, Sonic does indeed live on this chip!
Like always, to open this part I am using hot air from my hot air rework station to open these parts. I have both the air speed and temperature knobs cranked to 11 ( temperature is set to 480 degrees C). After about 30 seconds or so on each side, I carefully nip away at the plastic, which almost falls apart from what the heat has done to the material. When enough of the die is exposed, I gently push on it (while still heating it) until it breaks free. Sometimes this can be risky though, as the tool I use to push can easily leave a mark on the die, or there is always a chance that the epoxy will stick to the die and come with it. This part was one of the easiest times I've had opening part though.
I hope you enjoy seeing Sonic as much as I did!

It's really beautiful how such a microscopic system is implemented in rows. It's like a farm field from a bird's eye view, or a tanker gas plant. Or some other industrialized plant in bird's eye view all micro.
Just what I was looking for, calm and clear chip decapping and analysis. Thanks.
Stuff like that is such an amazing peak into the astounding achievements of humankind.
That is the single most amazing thing ive ever seen.
Wow, really clean decap. Nice job!
It's beautiful what a work of art
Great work and fantastic part.
Nice. This is definitely the best way to go about decapping without the need for any dangerous acids. What temp did you have the heatgun on? I'm finding that a lot of the time the glue on the carrier frame melts before the epoxy releases, which ends up cracking the die.

Nice work! I used to work for the guy who outed these chip signatures.
I wonder if it was some easter egg or some joke that is both put for humor and garenteed product confidence for speed and performance. Still cool. What was the chip designed for?
I came here from a instagram post.
Bro this is so awesome. But what is this and what does it?
this answer is a bit late but whatever... This IC (integrated circuit) is belonging to the family of DSP (digital signal processing). To put in very easy words. It transforms analog signals (like temperature e.g. 39°C which is measured and then put into a specific voltage) into a digital signal (which then is changed from a specific voltage to a string of ones and zeros). You can find a more complex answer on wikipedia. Hope that helps a little. :)
What type of microscope do you use? Also what is your highest magnification.
Increible !!
this is how you get blast processing, you put Sonic inside™
TAAM
TADA DADAM!
Nice...!
Ho to know it is "sonic edition"? Does the ADSP-2181 KS-160 (PQFP) have it?
I would speculate that any ADSP-2181 part will have it, regardless of the package type. That being said, I have only opened up this specific part. 😁
@@EvilmonkeyzDesignzMore than likely they would have the same die inside and just the package is different.
Man I wish I had one of those metallurgical microscopes but they’re so expensive
What do you do if some of the package does not separate from the top of the die
I'll have to do a video on the process, but essentially the easiest method is to boil the chip in pine gum rosin. I have some videos of the process on Instagram, but nothing comprehensive.
We do a small bit of tomfoolery
I have tried decapping ICs like this and I have't had great success, i usually break the chip or the encapsulation remains stuck to the chip.
Когда-то давно я по TV смотрел передачу про фотографа который фотографирует чипы и находил изображения ракеты или ещё чего-то. Оказалось, что это что-то типа графити, так разработчики микро чипов оставляли свой след.
Shouldn't be too hard to replicate this chip with a breadboard.
wow
I subd so hard
I decap ic with fire
