I PERFORMED IC SURGERY on an analog amplifier, custom dip-16. Removed the gold cover. Pretty huge 1980s stuff, gold-on-ceramic hybrid. But still. This was a custom IC, a patchclamp front end with a peltier- cooled discrete amp, with a tiny peltier block, thermistor, and a three-jfets diff amp. And a large piece of a dessicant pellet. The thermistor had gone crazy from old age, shutting down their -30C cooling.

I've never had leadbond chips open before. I mean, besides looking inside those ancient Western Digital 6805-type microcontrollers with the eprom window.
Mantis inspection microscopes: still NOT cheap on eBay.
