Abstract
An electronic device includes a casing, a main circuit board, a detachable component and a flexible circuit board. The main circuit board is disposed in the casing. The main circuit board includes a processor and a memory, wherein the memory stores data. The detachable component is disposed in the casing. The flexible circuit board includes a first end portion, a second end portion, a middle portion and a first detection loop, wherein the first detection loop is disposed at the first end portion and the middle portion. The first end portion is electrically connected to the main circuit board and the second end portion is fixed on the detachable component. When the detachable component is detached from the casing, the middle portion breaks, such that the first detection loop is cut off. When the first detection loop is cut off, the processor erases the data stored in the memory.
