I like it. I've used sandpaper to solve some interesting problems in the past as well with great success. I suspect we are only seeing the beginnings here in a trend of high-tech applications of fine grit paper.

I expect it's much easier to acquire fine sandpaper, yet my inner child yearns for laser decapping. (Or I suppose more than "decapping", depending on the depth.)

  High power lasers are becoming more and more affordable. Laser ablation is definitely an option but you really want to have some proper fume extraction around that.

  Laser decapping will destroy the die, except if you have a rare package that does not mix glass in the epoxy. You could still compare the internal structure of the package and bonding, but the die itself is mostly destroyed.

I'm off to build an MCP so AI can control the sandpaper

  You may as well start off with one of these then: https://phillipscorp.com/india/phillipsgrinding/phillips-surface-grinder/ https://phillipscorp.com/india/phillipsgrinding/phillips-sur... All you need is a serial port and some G-codes.

    Surface grinders generally don’t use CNC, they are a simple machine.

      This is a fun playlist of a conversion of a manual machine to CNC: https://www.youtube.com/playlist?list=PLDlWKv7KIIr9rlCwZ9K43KoI_UZj36gOa https://www.youtube.com/playlist?list=PLDlWKv7KIIr9rlCwZ9K43...

      In the 1950's, yes. But these days they definitely are CNC based. https://www.rooy.nl/en/areas-of-expertise/surface-grinding/ https://www.rooy.nl/en/areas-of-expertise/surface-grinding/
