- Component Refurbishment: Technicians re-solder damaged connections, replace malfunctioning microswitches, or repair harmed transponder coils.
- Shell Replacement: Because the original housing must be cut open, specialists usually house the repaired circuit board inside a brand-new, beautiful plastic shell.
