Abstract:
Disclosed is a package substrate, in which the plating area of a first plating layer formed on a layer which is to be connected to a motherboard is larger than the plating area of a second plating layer formed on a layer which is to be connected to an electronic part, and the plating thickness of the second plating layer is greater than the plating thickness of the first plating layer, thus balancing the plating volumes of the plating layers formed on the layers of the package substrate, thereby minimizing warpage of the package substrate which results from the coefficients of thermal expansion being different.
Abstract:
Disclosed is a package substrate including a solder resist layer having pattern parts and a method of fabricating the same, in which the pattern parts are formed on the solder resist layer, thus increasing heat dissipation efficiency and minimizing the warpage of the substrate.
Abstract:
A set-top box, which allows a user to input a key command in real time while displaying an animation sequence on an on-screen display (OSD) screen, and a method of outputting the OSD data of the set-top box. The set-top box includes a reception module that receives digital broadcast signals, a demultiplexer that extracts a broadcast signal of a channel selected by a user from the received digital broadcast signals, a decoding module that decodes the extracted broadcast signal using a predetermined method, an on-screen display (OSD) control module that divides OSD animation data into a plurality of subsets, loads each of the subsets in every operating cycle, determines whether a user has input a key command in every operating cycle, and selectively provides the loaded subsets based on the determination result in every operating cycle, wherein the OSD animation data realizes an animation sequence when displayed. The set-top box further includes a combination control module that receives the loaded subsets of the OSD animation data from the OSD control module and overlays the data onto the decoded broadcast signal and provides the overlaid result to a display device.
