はじめに
In this guide, the repair that is demonstrated is of a loose black negative electrical wire of the solar cell in the SHARP EL-520X series of calculator, and the guide gives you step by step instructions on how to re-solder it back to the calculator's circuit board.
Sometimes the wiring of an electronic device can get loose from something as simple as a light knock and then fall out of place and the factory soldering is very thin on the circuit board.
You don't need to be too shy on how much solder you use as there is enough empty space in the calculator casing to accommodate a bit extra solder if you feel it will provide more security to keep the wire in place.
