Abstract: A method for forming a frame attachment interconnect between a substrate and a frame is disclosed. The method can include applying a composite material (e.g., epoxy-glass prepreg) to a surface of a substrate. The composite material can have one or more holes disposed to substantially align with a corresponding pad on the surface of the substrate. A metal disc is placed in each hole of the composite material on top of the corresponding pad. A frame member can be placed on top of the composite material and the metal discs. The frame member can have one or more pads disposed to substantially align with the metal discs. The substrate, composite material, metal discs and frame combination can be cured in a controlled atmosphere that can include a vacuum and a predetermined temperature to create discrete electrical connections between adjacent pads but with each encapsulated and electrically isolated.

Abstract: A semiconductor device is provided that includes a semiconductor chip, a plurality of solder bumps that electrically couple the semiconductor chip to the outside, and a metal bump being provided on the surface of each first solder bump which is at least a part of the plurality of solder bumps and being made of a metal having a melting point higher than that of the first solder bump. The wettability of the first solder bump is improved as each metal bump serves as a core when the corresponding first solder bump melts. Thus, the connection reliability of the first solder bump can be improved.

Then, semiconductor chip is positioned to hold the solder bumps in contact with the posts of the first group, and the solder bumps are melted to join the solder bumps to the posts of the first group. Thereafter, the second layer is cut between the posts of the first and second groups, producing separate multilayer posts.

Abstract: A method and system of utilizing inexpensively manufactured, electrically conductive and mechanically compliant disks to interconnect an area grid array (“AGA”) chip to a printed wiring board. The conductive disk shaped leads are stamped from a thin sheet of conductive material. To increase solderability and protect the disk surface, the disks can be plated with tin or an equivalent material. Each disk is positioned tangent to the surface of an AGA chip in a specific orientation. One edge of each disk is electrically connected and mechanically secured to a corresponding conductive pad located on the surface of the AGA chip. The opposite edge of each conductive disk is positioned to align with a corresponding conductive surface pad on a printed wiring board (“PWB”). Each opposite edge is electrically connected and mechanically secured to the surface of the PWB, thereby establishing a compliant electrical connection between the AGA chip and the PWB.

Abstract: A solder preform is provided for forming interconnections between multilayer ceramic substrates comprising an upper layer and lower layer of solder separated by an intermediate layer of a material which is wettable by solder and which does not melt at the temperatures used to reflow the solder and form the connections. The solder preform is used to join the substrates and is particularly useful to simultaneously electrically interconnect the substrates and to form a hermetic seal between the substrates being joined.

Abstract: Pads which are attached to a high density printed circuit board (PCB) having a plurality of through-holes opening on the top surface. A plurality of pads are formed on a carrier sheet so that each of the pads have a copper layer proximate to the carrier sheet and a joining metal layer formed on top of said copper layer. The plurality of pads are positioned on the carrier sheet so that they are aligned with the through-hole pattern on the top surface of the PCB, the pads bing laminated to the through-holes on the top surface using the joining metal, and the carrier sheet being separated from the plurality of pads that are joined to the through-holes so that the copper layer is exposed. The pads may possess a variety of shapes such as disk-shaped, elongated, or rectangular, and can cover one or multiple through-holes. An electrical component may be soldered to the pad. The pad and through-hole may be compressed so that the top surface of the pad is even (flush) with the top surface of an external dielectric surface.
