A Universal-Serial-Bus (USB) device has a USB plug that is centered over a center-line of a circuit board. The circuit board with flash memory and a USB flash controller has metal pads that a USB connector is soldered to. The USB connector has a rear step that is about half the height of the USB connector plug. Contacts on the rear step are soldered to the metal pads on the circuit board so that the USB connector is centered around the edge of the circuit board. The overall height of the flash device can be reduced since the bulky USB connector is not attached off-center to the circuit board, but is attached at the half-height rear step. Both the USB connector and the circuit board share the same center line, allowing a printed-circuit board assembly (PCBA) to be symmetric around the center line.
