Abstract:
1. A removably connectable Universal Serial Bus (USB) memory card comprising: rectangularly-shaped tube metal housing; Chip-On-Board (COB)-USB device; carrier substrate having a U-block disposed on one side thereof and protruding from a back side of the carrier substrate and extending partially above the bottom surface of the carrier substrate forming a U-shaped structure; a rectangular depression formed in the bottom surface of the carrier substrate, for receiving a thermo set adhesion tape that causes the COB-USB device to be thermally taped to the carrier substrate when heated, the carrier substrate and the COB-USB device forming a USB card sub-assembly, the USB card sub-assembly being securely located inside the rectangularly-shaped tube metal housing with the U-block serving to stop the COB-USB device from slipping out of the metal housing, wherein a light-emitting diode (LED) is disposed substantially on the top of the COB-USB device and on a side thereof that is below the U-block, a LED window made of transparent plastic disposed substantially in the middle of the back side of the metal housing; a cavity hole disposed substantially on the bottom center of the U-block, wherein the LED is housed inside the cavity hole when the COB-USB device is inserted into the carrier substrate, and the LED window allows emitting light from the LED to travel through the inside of the USB memory card sub-assembly thereby indicating that the USB memory card is active when lit, and inactive when not lit.
