Title: Partially patterned lead frames and methods of making and using the same in semiconductor packaging
Inventor: ISLAM SHAFIDUL
IPC: H01L21/68
Filed: 2004-01-15
Abstract: A method of making a lead frame and a partially patterned lead frame package with near-chip scale packaging (CSP) lead-counts is disclosed, wherein the method lends itself to better automation of the manufacturing line as well as to improving the quality and reliability of the packages produced therefrom. This is accomplished by performing a major portion of the manufacturing process steps with a partially patterned strip of metal formed into a web-like lead frame on one side, in contrast with the conventional fully etched stencil-like lead frames, so that the web-like lead frame, which is solid and flat on the other side is also rigid mechanically and robust thermally to perform without distortion or deformation during the chip-attach and wire bond processes, both at the chip level and the package level. The bottom side of the metal lead frame is patterned to isolate the chip-pad and the wire bond contacts only after the front side, including the chip and wires, is hermetically sealed with an encapsulant. The resultant package being electrically isolated enables strip testing and reliable singulation without having to cut into any additional metal. The use of the instant partially patterned lead frame in making ELP, ELPF and ELGA-type CSPs is also disclosed.

Title: A production method and structure of blinds slat capable of changing visual effects with lights
Inventor: CHEN SHUI-HU
Filed: 2004-01-27
Abstract: This invention relates to a production method and structure of blinds slat of which the visual effects can change with light. The method comprises the following steps: preparing a semi-transparent base-sheet, spreading a number of scenic-pieces such as dry flower or leaf flakes evenly on the base-sheet, and using a surface-sheet with higher transparency to cover atop the scenic-pieces. Then adhere the surface-sheet with the base-sheet so as to fix the scenic-pieces in between the surface- and the base-sheets. Due to the different transparencies of the surface-sheet and the base-sheet, the scenic-pieces embedded in the slat can present different visual effects when the lights from the two sides change; and this, therefore, will increase the beautifulness of the blinds.

Abstract: A backlight driving circuit is controlled by a timing controller and execute on/off control of the backlights. The timing controller detects, using the synchronous signal, change in a blank period which is of one frame period for display of one screen and during which the image signal is not transmitted. Upon detecting the change in the blank period, the timing controller adjusts on-periods of the backlights in order to make brightness of the backlights equal to one another. Consequently, the backlights have equal brightness with one other in spite of the change in the blank period. This makes the lives of the backlights equal to one another. In a case where the plural backlights constitute a backlight unit, it is able to prevent reduction in life of the backlight unit. Further, it is also possible to prevent brightness of the backlights from being differentiated even through a long-term use.
