Placing disassembled screws on double sided tape is such a great idea, I am going to try that next time I disassemble my electronics (as opposed dropping everything in a container and spend time finding the original size screws during reassembly).
I’ve also seen a clever technique of drawing a diagram of whatever you’re working on on cardboard, and stabbing the screw into the cardboard to keep track of where everything lives
Roughly in the layout of the way they came out. Top to bottom, in layers, as it comes apart.
A habit from working on laptops in a warranty center. I might have to try some tape.
