Patent number: 8567050Abstract: A dual-personality extended USB (EUSB) system supports both USB and EUSB memory cards using an extended 9-pin EUSB socket. Each EUSB device 101 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. A single-shot molding process is used to form both an upper housing portion on the upper PCB surface that includes ribs extending between adjacent contact pads, and a lower molded housing portion that is formed 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.Type: GrantFiled: October 14, 2011Date of Patent: October 29, 2013Assignee: Super Talent Technology, Corp.Inventors: Siew S.

Patent number: 8254134Abstract: A Secure Digital device including a PCBA having passive components mounted on a PCB using surface mount technology (SMT) techniques, and active components (e.g., controller and flash memory) mounted using chip-on-board (COB) techniques. The components are mounted only on one side of the PCB, and then a molded plastic casing is formed over both sides of the PCB such that the components are encased in the plastic, and a thin plastic layer is formed over the PCB surface opposite to the components. The molded plastic casing is formed to include openings that expose metal contacts provided on the PCB, and ribs that separate the openings. The molded plastic casing defines a pre-molded switch slot that facilitates an insert-in switch assembly process for mounting a write protect switch. The write protect switch includes a movable switch button engaged in the switch slot, and a switch cap secured over the switch slot.Type: GrantFiled: January 8, 2010Date of Patent: August 28, 2012Assignee: Super Talent Electronics, Inc.Inventors: Siew S.

Patent number: 8240034Abstract: According to certain embodiments of the invention, a flash memory card is manufactured using COB processes on a PCB panel with multiple micro cards PCB substrates. These micro memory cards are laid out in an array of 3×5 matrixes of micro cards PCB substrates. A method of molding over a PCBA is utilized, contrary to a conventional method of having two or more pieces of package components to tape together. This results in a simpler structure without the notch which enables easier singulation process and the package is moisture resistance. The final product is a single piece versus two or three pieces glued up pieces and would not separate from pieces. The final product has high water and moisture resistance, low cost and fast manufacturing throughput, no seam and aesthetically more appeasing, can stack more layers of flash memory die, and be maximized XY spaces to accommodate larger size flash memory die.Type: GrantFiled: May 28, 2008Date of Patent: August 14, 2012Assignee: Super Talent Electronics, Inc.Inventors: Siew S.

Patent number: 8141240Abstract: A method for fabricating MicroSD devices includes forming a PCB panel having multiple PCBs arranged in parallel rows, with each PCB connected to its neighboring PCBs in each row by relatively narrow connecting bridge pieces, and separated from PCBs of adjacent rows by elongated stamped out blank slots. Passive components are attached by conventional surface mount technology (SMT) techniques. IC chips, including a MicroSD controller chip and a flash memory chip, are attached to the PCB by wire bonding or other chip-on-board (COB) technique. A molded housing is then formed over the IC chips and passive components using a mold that prevents formation of plastic on the upper surface of each PCB. The connecting bridge pieces are then cut using using a rotary saw. A front edge chamfer process is then performed.Type: GrantFiled: December 28, 2007Date of Patent: March 27, 2012Assignee: Super Talent Electronics, Inc.Inventors: Siew S.

Patent number: 8102662Abstract: A USB device including a bistable mechanism that serves to bias a plug connector into one of two stable states, where the first stable state is associated with a retracted position in which the plug connector is fully retracted inside a housing, and the second stable state is associated with a deployed position in which the plug connector extends through the front opening for coupling to a host system. Movement of the plug connector form the retracted to the deployed position is performed by manually applying a force to a handle portion that protrudes through a slot defined in the housing. The bistable mechanism resists the deploying force until an equilibrium point is reach, after which the bistable mechanism releases stored potential energy to complete the deploying process and to maintain the plug connector is the deployed position.Type: GrantFiled: September 1, 2009Date of Patent: January 24, 2012Assignee: Super Talent Electronics, Inc.Inventors: Siew S.
