I Took Apart A PIC18

(1/4) > >>

Lance:
Following the motto of this site, I didn't turn it on! I tried to turn it on, discovered it was burnt out, and then took it apart. The component in question is a PIC18. I just sanded the top off until I got down to the lead layer. I didn't have a proper sander available to me, so I just went at it with a sandpaper bit on a drill. A few times the drill got traction and pulled around, so some of the pins got wrecked. All things considered it came out rather well. Not a neat job by any means.

Did I destroy the IC? Or can I lightly remove some more to get at it?

Time:
Why did you sand the solder mask off?

armandas:
Dude, picture cropping - use it!!

Back to topic: interesting picture, thanks for sharing. I have extracted the silicon parts by torching ICs. It's not too fascinating without a microscope though.

Jon Chandler:
SparkFun has had a few recent columns on dissecting ICs.  The first, a few months ago, was looking at SD cards.  The second was a counterfeit ATMEL part. Lots of awesome pictures and a discussion about how the pros do it.

Time:
Oh, nevermind I see whats going on here.  This is an IC, I thought it was PCB for some reason.
