Improved my method for decapsulating chips better.
I used a Mr coffee, coffee pot heat plate. With expendable metal plate on top. Used my drill press as a mill with a tungsten carbide drill bit making a small pocket in the chip for the acid to sit in.
I heated up the chips first on the plate then applied a drop of nitric acid. Rinsed with water, heated again then a drop of sulfuric acid water rinse. Then repeated till the dies were exposed.
Some previews of some of the custom chips in the xbox 360 decapsulated.
Still trying to get the best focus and image quality from this new cheap Chinese usb microscope.
