Abstract:
1. A flash memory card, being a structure that uses a rigid flexible board to connect a flash memory card unit and a universal serial bus unit, said flash memory card unit is disposed at an end of said flash memory card, said flash memory card unit comprises a flash memory card communication interface and a flash memory card memory chip set, and said universal serial bus unit is disposed at another end of said flash memory card, said universal serial bus unit comprises a universal serial bus communication interface and a processor chip, wherein a rigid flexible board is provided for connecting an electric signal between said flash memory card communication interface and said universal serial bus communication interface, and said rigid flexible board comprises two rigid printed circuit boards and a flexible printed circuit board thermally pressed and attached with each other, wherein said two rigid printed circuit boards are wholly thermally pressed and attached on said flexible printed circuit board, and said flash memory card communication interface and said universal serial bus communication interface are disposed on said rigid printed circuit boards, and said processor chip and said flash memory card memory chip set are disposed on said flexible printed circuit board, and a bending characteristic of said flexible printed circuit board is used to maintain a height difference between a planes of said flash memory card communication interface and said universal serial bus communication interface, so that said flash memory card is configured to concurrently have said universal serial bus communication interface and said flash memory card communication interface, and enhance the applicability of said flash memory card, wherein a side panel mounted adjacent to the universal serial bus unit is movable.
