1. A low-profile Universal-Serial-Bus (USB) device comprising:
- a printed circuit board assembly (PCBA) including;
a printed circuit board (PCB) including a relatively wide PCB handle section and a relatively narrow PCB plug section, the PCB having opposing first and second surfaces,a plurality of metal contacts disposed on the first surface of the PCB plug section,at least one integrated circuit (IC) mounted on the second surface of the PCB, the IC including means for processing USB signals, anda plurality of conductive traces mounted on the PCB, each conductive trace extending between an associated metal contact and the IC; and
a housing attached to the PCBA and including a cover plate extending over both the PCB handle section and the PCB plug section,wherein the cover plate includes a planar surface that is parallel to the PCB,wherein a first thickness measured between the first surface of the PCB and the planar surface adjacent to the metal contacts is substantially equal to a second thickness between the first surface of the PCB and the planar surface adjacent to the IC, andwherein substantially all of the housing is located between the first surface and the cover plate.

Abstract
A low-profile Universal-Serial-Bus (USB) device includes a PCBA in which all of the ICs are formed on a side of a PCB opposite to the metal contacts. The ICs include, for example, a USB controller chip and flash memory chip or communication chip. A housing is attached over the ICs and extends a minimum height above the metal contacts.

21. A method for manufacturing (Universal Serial Bus) devices comprising:
-
forming a first housing portion including a first cover plate and a peripheral wall extending from the first cover plate and defining a plurality of peripheral slots, a second housing portion including a second peripheral wall having a plurality of tabs extending from the peripheral wall, and a PCBA; and snap-coupling the second housing portion to the first housing portion such that each of the tabs is received inside a corresponding slot of the plurality of peripheral slots, and such that the PCBA is sandwiched between first and second housing portions with a first adhesive layer between a first surface of the PCBA and the first cover plate and a second adhesive layer between a second surface of the PCBA and the second cover plate.
