Opening a TO-3 without damaging it

[Simon123]

I remember a YouTube video where a guy used acid and heat to remove the packaging from some chips. Didn't seem to affect anything inside, but acid could be messy to work with...

Proably they were sandwich like chips and the acid-hydrochloric eats cement or what that white stuf is. But it will also eat bond wires.

Nitric acid will not eat the bond wires but will oxidize the plastic very nicely. Most stuff that would eat the steel outside would eat the bond wires inside. I don't have any TO-3's to test it on otherwise I would see how well nitric works on the case. We just got a fresh bottle in at work.

TO-3 cases are solid metal. So it probably wouldn't work.
