The adult version of the kids’ game, Operation, where you remove “organs” from a patient is the game of smartphone repair.
I just replaced the battery on an old iPhone 7. I probably spent half my time just trying to seat the microscopic screws so I could put them back in.
Also at that size a Y000 screw is almost indistinguishable from a PH000 screw. The Y has a 3-way pattern and the PH is the Philips 4-way pattern. They both look just like dots to the naked eye.
Getting the case open and getting the screws back in was the hardest part of doing my own battery replacement.
@sysop408 Do you have one of those lights with a magnifying glass in it? Sounds like an ideal application for that kind of gear.
@Wyatt_H_Knott as hard as it is to see, even worse is that manipulating the screws is like trying to arrange splinters in a pattern. I need to have hands the size of a rat’s paws.
At that size, a magnetic screwdriver tip is both a blessing and a curse. I need it because I can’t manipulate the screws with my fingers, but with screws that tiny, the slightest bump and the screw disorients and sticks to the screwdriver sideways.
I’m sure the pros have some specialized tools to make this easier including those wearable jeweler loupes and clamp mounted loupes, but tiny tools is my issue.
@sysop408 I have seen tiny screwdrivers with spring clamp fingers to hold the heads against the tip. there is surely also a tiny collar keeper that works the same as the full sized one - basically a tube around the shaft of the screwdriver that just clears teh head, so the screw is fully retained in the correct orientation for the entire screwing-in.
