Assignee:
Super Talent Electronics, Inc. - San Jose CA
International Classification:
H05K 7/02
US Classification:
361737, 361752, 439945, 235492
Abstract:
A socket having thirteen contact springs arranged in a manner that supports existing MMC and SD form factors, and also supports a combination SD/MMC flash memory card. The combination memory card includes a PCB assembly that is consistent with existing 13-pad MMC mechanical form factors, and a housing that is consistent with the SD mechanical form factor, thereby providing a single PCBA and housing arrangement that can be used to produce both MMC and SD memory cards. The thirteen contact pads support all MMC and SD contact pad patterns, but are modified to facilitate a write protect switch. The contacts springs of the socket are arranged to make contact with the modified pad pattern, but to also be backward compatible with existing SD and MMC form factors. A system including the socket and combination SD/MMC flash memory card is also disclosed.
Manufacturing Method For Memory Card
US Patent:

Assignee:
Super Talent Electronics, Inc. - San Jose CA
International Classification:
H05K 3/30
US Classification:
29841, 29830, 29842, 29855, 29412, 29417, 361737
Abstract:
A portable memory card including a molded plastic casing formed over a memory device and other circuits mounted on a substrate such that the molding material extends over side edges of the substrate to provide accurate width and thickness dimensions. Contact pads are formed on a lower surface of the PCBA substrate, which is exposed through a bottom of the casing. The PCBA is fabricated on a substrate carrier, then positioned inside of a mold assembly. During the molding process, a rod extends from an upper portion of the mold assembly and pushes the substrate against the lower surface. A vacuum is then applied to hold the substrate against the lower surface of the mold, and the rod is subsequently withdrawn from the mold cavity during injection of the molten molding material. A single cavity mold assembly provides molding material extends over front and back edges of the memory card.

Assignee:
Super Talent Electronics, Inc. - San Jose CA
International Classification:
H01L 21/98
US Classification:
438107, 438126, 257E217
Abstract:
Plastic casings are simultaneously molded onto several PCBAs attached to a carrier in a closely-spaced arrangement. All edges of each PCBA have integral connecting segments that extend through grooves formed in the associated mold assembly, and are pinched when the molds assembly is closed to precisely and reliably position the PCBA inside of an associated cavity during the molding process. In one embodiment, the PCB substrate is positioned in a bent arrangement to accommodate the use of inexpensive memory devices. Write-protect switches are provided.

Assignee:
Super Talent Electronics, Inc. - San Jose CA
International Classification:
G06K 19/06
US Classification:
235492, 235441
Abstract:
A memory card including a PCB assembly that is consistent with existing 13-pad MMC mechanical form factors, and a housing that is consistent with the SD mechanical form factor, thereby providing a single PCBA and housing arrangement that can be used to produce both MMC and SD memory cards. The thirteen contact pads support all MMC and SD contact pad patterns, but are modified to facilitate a write protect switch. The housing includes an enlarged window (or windows) that exposes two or more contact pads in each of the multiple rows, thereby facilitating slidable insertion of the memory card into a socket of a host system. Alignment notches are formed in the side edges of the PCB, and/or alignment pins are utilized for properly aligning the PCBA within the housing.
Card-Type Electronic Apparatus Assembly Using Ultrasonic Joining

Assignee:
Super Talent Electronics, Inc. - San Jose CA
International Classification:
H05K 5/00
US Classification:
361752, 361800
Abstract:
A card-type electronic apparatus such as an SD card, a CF card, a Memory Stick card, or a USB flash drive is formed from an upper and lower cover that are bonded together at an interior seam formed using ultrasonic joining. Lower sidewalls on the lower cover create an installation pocket for the upper cover. The installation pocket not only simplifies alignment between the upper and lower covers, but also contains any bonder material overflow that might otherwise affect the external dimensions of the apparatus housing. The lower sidewalls can completely surround the upper cover, for drop in installation. Alternatively, the lower sidewalls can partially surround the upper cover, so that the upper cover can be slid into place during assembly.
