Inside an LM3886

Denis.BR · 23rd March 2007, 02:26 AM

Unfortunately, I literally burned 2 ICs, so I took a sandpaper to see how it is inside, and took some pics in the digital microscope:

The upper part is under the silicon, I sandpapered it too much.

The National N

This is another IC. The black part in the V+ bus is where the S$hit happened.

cool pics!

Very neat. At least you know it was an authentic part.

holy fu#@!%g sh!*!!! i had seen one that i blew up and then opened but didnt see that. i guess i didnt investigate enough. amazing technology these days man, amazing.
nice shots thanks.

oh my god now that i read your post im even more amazed. no wonder i didnt see that, you need a microscope.

Denis.BR · 23rd March 2007, 03:26 PM

yep, no microscope, no sight. At naked eyes you an only see a tiny silver square with no details.

Maybe a good magnifying glass can help.

if this IC, that can be a mid end IC, is this complex, I was wondering how a Intel Dual Core can look like

pretty damn complex, just think how long it would take to find the bit that say 'Bill gates sucks'

BILL GATES IS CHILL, YOU MUST BE AN APPLE GUY HUH, APPLE GUYS ALWAYS HATE ON US PC'ERS.

BUT YEAH AN INTEL PROCESSOR ONLY HAS SOME 2-3 "MILLION" TRANSISTORS.

Is that all? how about a modern graphics card like the nvidia 8800 gtx? Have a guess how many transistors are just in the core...

It is more than 3 million..

But more than 10 million?...

681 million

i correct myself. i just read that as of 2006 a microprocesser can have as much as "1.7 BILLION" transistors. (MOSFETS!)
