    摘要: A substrate, an alignment plate, a heat sink, a back plate, a plurality of spacers, and a plurality of nuts are used to removably package one or more semiconductor package into a single module. The semiconductor dies are packaged with tape automated bonding (TAB) packages having land grid array (LGA) outer lead bumps. The substrate comprises a number of land patterns, a number of alignment cavities, and a number of join cavities. The alignment plate is fabricated with a number of alignment pins, a number of housing cavities, and a number of join cavities. The heat sink is fabricated with a number of stems and a number of join cavities. The back plate is fabricated with a number of extrusions having threaded ends. The spacers are fabricated with flanged openings at both ends, and each spacer is loaded with a number of spring washers. The nuts are fabricated with stepped heads. The extrusions, the land patterns and the alignment and join cavities of the substrate, the alignment pins and the housing and join cavities of the alignment plate, the stems and the join cavities of the heat sink, the spring washer loaded spacers, and the stepped head nuts are coordinated in their numbers, sizes and geometric locations, as a result, the semiconductor packages may be easily replaced at a later time with enhanced versions, and the replaced semiconductor packages are salvageable. In some embodiments, a biasing member, such as a leaf spring, is provided in each housing cavity (aperture) of the alignment plate for biasing the semiconductor packages against one or more walls of each aperture.

    摘要: A liquid cooling module for semiconductor chips is disclosed. The module includes a plurality of substrates, each containing at least one chip. The substrates are arranged in the module so that when coolant flows through the module, the coolant is exposed to the top and bottom surfaces of the chips. A gasket is used between each substrate. The gasket is made if a Z-axis elastromeric material that is impervious to liquid and therefore directs the flow of the coolant in the module and makes the module liquid tight. The material also is conductive in the Z direction, but not the X or Y direction, thereby making electrical communication between the chips on different substrate levels possible. The module is intended to be attached to a circuit board, thus simplifying the layout of liquid cooled chips on the board.

    摘要: A film of elastomeric material is used to laminate the tape with LGA outer lead bumps to the stiffner plate of the semiconductor package. The elastomeric material has the necessary physical and electrical characteristics to provide the required firmness to maintain good electrical contact between the outer lead bumps and the corresponding contacting pads on a socket, ceramic substrate or PWB, and at the same time, to provide the required resilience to accommodate differences in heights between the outer lead bumps. The stiffner plate is fabricated with a cavity at its center for accommodating the VLSI die, and slots along the outer edges of its underside for storing the excess elastomeric material squeezed out when laminating the tape to the stiffner plate, thereby preventing the excess squeezed out elastomeric material from building up at the outer edges of the semiconductor package to a height in excess of the outer lead bumps. As a result, the land pattern on the socket, ceramic substrate or PWB is not required to address the differences in heights between the outer lead bumps.
