    • An electronic device includes an FPC, a circuit chip arranged on the flexible flat cable, a heat sink arranged on the circuit chip to release a heat of the circuit chip, and an elastic member arranged on a lower surface of the FPC. The upper surface of the FPC is large enough to cover a contact surface of the circuit chip. The elastic member does not overlap with an apex portion of the circuit chip, but overlaps with the circuit chip at an inner side of the apex portion. Therefore the elastic member does not press the FPC against the apex portion of the circuit chip. Accordingly, the FPC at a position corresponding to an apex of the circuit chip is suppressed from being distorted, and there is no fear of breaking of wire and exfoliation of the circuit chip.
    • 电子设备包括FPC,布置在柔性扁平电缆上的电路芯片,布置在电路芯片上以散发电路芯片的热量的散热器,以及布置在FPC的下表面上的弹性构件。 FPC的上表面足够大以覆盖电路芯片的接触表面。 弹性构件不与电路芯片的顶点重叠,而是在顶部的内侧与电路芯片重叠。 因此,弹性部件不将FPC压靠在电路芯片的顶点部。 因此,抑制了与电路芯片的顶点对应的位置处的FPC的失真,不会发生电线断线和电路芯片的剥离。
