Extended COB-USB With Dual-Personality Contacts
First Claim
1. An extended Universal-Serial-Bus (EUSB) device comprising:
- a printed circuit board assembly (PCBA) including;
a printed circuit board (PCB) including a front edge, the PCB having opposing first and second surfaces and defining a plurality of openings extending between the opposing first and second surfaces and located adjacent to the front edge,a plurality of metal contact pads disposed on the first surface of the PCB and located between the front edge and the plurality of openings,a plurality of metal contact springs, each metal contact spring extending through a corresponding opening of said plurality of openings such that a contact portion of said each metal contact spring protrudes from said first surface;
at least one passive component mounted on the second surface of the PCB handle section; and
at least one integrated circuit (IC) mounted on the second surface of the PCB handle section; and
a single-piece molded housing formed on the second surface of the PCBA such that said at least one passive component and said at least one IC are covered by said molded housing, and such that substantially all of the first surface of the PCB is exposed.

Abstract
A dual-personality extended USB (EUSB) system supports both USB and EUSB memory cards using an extended 9-pin EUSB socket. Each EUSB memory card includes a PCBA having four standard USB metal contact pads disposed on an upper side of a PCB, and several extended purpose contact springs that extend through openings defined in the PCB. Passive components are mounted on a lower surface of the PCB using SMT methods, and IC dies are mounted using COB methods, and then the components and IC dies are covered by a plastic molded housing. The extended 9-pin EUSB socket includes standard USB contacts and extended use contacts that communicate with the PCBA through the standard USB metal contacts and the contact springs. The PCBA includes dual-personality electronics for USB and EUSB communications.
