Molding method for COB-EUSB devices and metal housing package
First Claim
1. A method for producing an Extended Universal-Serial-Bus (EUSB) device comprising:
- producing a printed circuit board (PCB) including opposing first and second surfaces, a plurality of input/output contact pads disposed on the first surface, a plurality of first contact pads disposed on the second surface;
mounting a plurality of contact springs onto the first surface of the PCB such that said contact springs are electrically connected to corresponding input/output contact pads of said plurality of input/output contact pads, wherein each of the plurality of contact springs includes a raised contact portion that protrudes above the first surface of said PCB;
attaching at least one integrated circuit (IC) to the first contact pads; and
forming a single-shot molded housing only on and entirely covering the second surface of the PCB such that said at least one IC is encased by said housing, and such that said PCB is disposed between an entirety of said housing and said contact springs, to produce said EUSB.

Abstract
A dual-personality extended USB (EUSB) system supports both USB and EUSB devices using an extended 9-pin EUSB socket. Each EUSB device includes a PCBA having four standard USB metal contact pads, and several extended purpose contact springs disposed on an upper side of a PCB. A single-shot molding process is used to form a molded housing over passive components and IC dies disposed on the lower PCB surface. The passive components are mounted using SMT methods, and the IC dies are mounted using COB methods. 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 EUSB device is optionally used as a modular insert that is mounted onto a metal or plastic case to provide a EUSB assembly having a plug shell similar to a standard USB male connector.
