摘要:
A cooling system for an electronic component on a component carrier is provided. The system includes a frame, a spray manifold, and a sealing member. The frame has an opening and is connectable to the component carrier so that an annular area is defined between the opening and the electronic component. The spray manifold is sealed over the opening to define a spray area over a back surface of the electronic component. The spray manifold sprays a cooling fluid on the back surface. The sealing member seals the annular region so that input/output connectors on the component carrier are isolated from the cooling fluid.

In using Ni(P) and Sn-rich solders in Pb free interconnections, the prevention and control of the formation of intermetallic compound inclusions, can be achieved through a reaction preventive or control layer that is positioned on top of an electroless Ni(P) metallization, such as by application of a thin layer of Sn on the Ni(P) or through the application of a thin layer of Cu on the Ni(P

摘要:
Improved interconnects are produced by injection molded solder which fills mold arrays with molten solder so that columns that have much greater height to width aspect ratios greater than one are formed, rather than conventional flip chip bumps. The columns may have filler particles or reinforcing conductors therein. In the interconnect structures produced, the cost and time of a subsequent underfill step is reduced or avoided. The problem of incompatibility with optical interconnects between chips because underfills require high loading of silica fillers which scatter light, is solved, thus allowing flip chips to incorporate optical interconnects.
摘要:
An interconnection structure suitable for flip-chip attachment of microelectronic device chips to packages, comprising a two, three or four layer ball-limiting composition including an adhesion/reaction barrier layer, and having a solder wettable layer reactive with components of a tin-containing lead free solder, so that the solderable layer can be totally consumed during soldering, but a barrier layer remains after being placed in contact with the lead free solder during soldering. One or more lead-free solder balls is selectively situated on the solder wetting layer, the lead-free solder balls comprising tin as a predominant component and one or more alloying components.

The present invention relates to an image signal transmission method in a network camera system, and more particularly, to a network camera system and an image signal transmission method in which a low resolution image formed by down-scaling a high resolution image photographed by a high resolution camera is displayed via a display means of a DVR system, and the high resolution image is compressed to be stored in a memory means of the DVR system, thereby preventing overload on the system that may occur due to compressing, transmitting, or decompressing a plurality of high resolution image signals. The network camera system including: a high resolution image photographing unit photographing an object to generate a high resolution image signal; an A/D converter converting the high resolution image signal into a digital image signal; an image signal compression unit receiving the digital image signals from the A/D conversion unit and generating a first image signal by compressing the digital image signal in high resolution; a network interface unit connected to a predetermined network cable, for transmitting the first image signal to a predetermined DVR system connected by the network cable; a down-scaling unit receiving the digital image signal from the A/D conversion unit and generating a second image signal by down-scaling the digital image signal; an image signal encoding unit converting the second image signal into an analog signal to be encoded to a second analog image signal; and an interface unit transmitting the first image signal and the second analog image signal to the DVR system.
