Abstract:
mp3 플레이어, 휴대폰, 게임기와 같은 포터블 기기에서 재생 목록을 자동으로 생성하는 파일 관리 방법 및 장치가 개시되어 있다. 본 발명은 소스 서버와 연결하여 소스 서버의 재생 파일들을 폴더 단위로 복사하여 파일 시스템에 저장하는 과정, 재생 파일이 복사되면 파일 시스템을 체크하여 추가된 파일의 유무를 판단하는 과정, 추가된 파일이 있으면 상기 파일 시스템의 파일 경로 정보에 따라 상기 폴더 단위의 파일들을 재생 목록으로 생성하는 과정을 포함한다.
Abstract:
A method and an apparatus for managing files for a portable device are provided to manage media files effectively by generating the play lists without the need of additional work of a user. Reproduction files of a source server are copied by the unit of folder and stored in a file system. When the reproduction files are copied, it is checked whether files are added in the file system(542). If there are added files, play lists for the files are created according to file path information of the file system(574). The portable device is connected to a source server(510). The song files for play lists are created by the unit of folder from the source server. A media folder of the portable device is searched by a searching program. The song files are copied in the media folder and the file information is stored in the system(548).
Abstract:
PURPOSE: A probe card is provided to be capable of preventing pad damage of a semiconductor chip, reducing set-up cost, and restraining the damage of a bump pad ball. CONSTITUTION: A probe card is provided with a disc type PCB(Printed Circuit Board)(40) having an opening portion at the center portion, a plurality of Ag patterns(42) formed along the edge portion of the PCB, and a plurality of bump patterns(46) formed along the opening portion of the PCB. The probe card further includes a rubber part(48) electrically connected with the bump patterns and an anisotropic conductive metal wire installed at the predetermined inner portion of the rubber part. At this time, the rubber part is made of silicon. At the time, the rubber part has a predetermined size as large as that of a wafer pad.

Abstract:
PURPOSE: A poly(imide-siloxane) compound useful as a passivation layer for tapeless LOC packaging is provided, thereby the poly(imide-siloxane) compound has higher adhesive strength to both silicon chip and lead frame, and good photoresist wetting so that it can be used in lithography processes. CONSTITUTION: The poly(imide-siloxane) compound is produced by reacting diamino siloxane compound represented by formula (1), diamine compound represented by formula (2), and aromatic tetracarboxylic acid anhydride represented by formula (3) in a polar solvent, in which R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are aromatics, aliphatics, halogenated carbohydrate, hydroxy or ether; m+n is an integer of from 0 to 1000; and the polar solvent is n-methyl-pyrolidine. An electric element containing the poly(imide-siloxane) as a passivation layer can be adhere to both silicon chip and lead frame without using adhesive agents or adhesive tapes.
