Abstract:
Systems and methods for communicating using various protocols through the Secured Digital (SD) physical interface are disclosed. The invention covers, among others, single-mode and multi-mode hosts, single-mode and multi-mode devices, as well as techniques for initializing these hosts and devices in order to facilitate the aforementioned communication.
Abstract:
A portable memory device includes a molded housing and a printed circuit board assembly (PCBA) encased with the molded housing such that a plug connector extends from one end. A lower housing portion is produced by injection molding using a first apparatus, and then the lower housing portion is transferred to a second molding apparatus. The PCBA is mounted onto the lower housing such that the plug connector is received in a protected region. The second molding apparatus is then closed, and an upper housing portion is injected molded over the PBCA and exposed peripheral edges of the lower housing portion such that the upper housing portion becomes fused to the lower housing portion. Multiple lower housing portions connected together by plastic tethers to form a plastic strip, which facilitates efficient transfer to the second molding apparatus as a unit. The tethers are subsequently removed (e.g., singulated) to form individual memory devices.
Abstract:
A PC card frame kit for housing a printed circuit board assembly (PCBA) including a board (PCB) and a connector mounted on a back edge of the PCB. The frame kit includes a frame including first and second parallel side rails and an end rail extending between first ends of the first and second side rails. The frame defines an open end and a longitudinal slot for slidably receiving the PCB. Side panels of the PC card frame kit are then snap-coupled onto the frame.
Abstract:
A PC card frame kit for housing a printed circuit board (PCB) assembly including a PC board and a connector mounted on a back edge of the PCB. The frame kit includes a frame including first and second parallel side rails and an end rail extending between first ends of the first and second side rails. A pair of panels is connected to opposite sides of the frame by substantially identical (e.g., male-type) connection structures that are provided on both panels. A pair of ground contacts is provided on opposite sides of the PCB assembly connector that respectively contact the two panels. A metal support (shroud) is incorporated into the frame to receive the ends of the connection structures extending from both panels.
Abstract:
A light-weight flash hard drive includes a printed circuit board assembly (PCBA) mounted in a housing formed by a plastic frame and a pair of metal panels that are mounted on the plastic frame over the PCBA. The PCBA includes a PC board and a plug connector that is mounted on a front edge of the PCB. The plastic frame includes first and second parallel side rails and a back end rail extending between back ends of the first and second side rails. The frame defines an open front end and a longitudinal platform for receiving and supporting the PCBA such that the plug connector is exposed through the open front end. The metal panels are either snap-coupled to the plastic frame or to each other. Alternatively, or in addition, an adhesive or insulating film is provided between the metal panels and the IC devices mounted on the PCBA.

Abstract:
A removable Flash integrated memory module card has a plastic shell and an integral Flash memory module. On the backside of the card, there are exposed contact pads. When the card is inserted into a card-hosting device, the card can communicate with the device through the exposed pads. The manufacturing method includes manufacturing of the memory module and utilizing plastic molding techniques for making the card outer body. The method involves preparing the substrate, mounting the components, testing the module, preparing the molding device, and molding the card body.
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.
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.
Abstract:
A memory card having thirteen contact pads arranged on a PCB in a manner that supports an integrated SD/MMC system. Eight contact pads form a front row, four contact pads form a second row behind the front row, and a thirteenth contact pad is located between the front and back rows adjacent to a chamfer formed on the PCB. An L-shaped gap region is provided between the first and second rows, and between the second row and side edge of the PCB. An optional alignment notch is defined along the side edge adjacent the second row. An optional alignment hole is defined between adjacent contact pads of the second row that receives an alignment pin passing between two covers of a two-part housing. The memory card electronics are compatible with either the MMC or SD protocols, and the housing is consistent with either the MMC or SD mechanical form factors.
