摘要： In a method of producing an integrated circuit assembly, an IC device is metallurgically bonded to a supporting substrate. The mounting of the IC device to the substrate also includes a polymeric underfill body adhesively bonding the IC device to the substrate. The polymeric underfill body is formed of a curable underfill composition comprising epoxy resin, anhydride curing agent for the epoxy resin, amine catalyst and a minor amount of an additional component selected from alkyl-substituted imidazole and phenyl-substituted imidazole. Such additional component may act as a catalyst, as used with an amine catalyst known catalyst for the polymerization reaction of the epoxy resin with the anhydride curing agent, may act as a co-catalyst. The polymeric underfill body has improved glass transition temperature values and improved coefficient of thermal expansion values to provide good thermal stress cycling life for the integrated circuit assembly. The additional component, such as N-methyl-imidazole, is used in minor amount, such as from 0.05 to 5.0 weight percent.

摘要： Electrically conductive adhesive compositions and methods for the preparation and use thereof, in which a solder powder, a chemically protected cross-linking agent with fluxing properties and a reactive monomer or polymer are the principal components. Depending upon the intended end use, the compositions comprise three or more of the following: a relatively high melting metal powder; solder powder; the active cross-linking agent which also serves as a fluxing agent; a resin; and a reactive monomer or polymer. The compositions are useful as improved conductive adhesives, such as for attaching electrical components to electrical circuits: the compositions comprising metal powder are ideally suited for creating the conductive paths on printed circuits. The compositions for forming conductive paths may first be applied to a substrate in the desired pattern of an electrical circuit, and then heated to cure it. During heating, the action of the cross-linking agent and optional reactive monomer or polymer within the mixture fluxes the metals, enabling sintering to occur between the metal powder and the solder powder.

摘要： A three dimensional multi-layer circuit structure is formed by partially etching a foil having a coating. A pre-circuit is formed by providing a metal foil, applying a photodefinable photoresist to each side of the metal foil, selectively exposing and developing the photoresist leaving exposed areas and unexposed areas and, plating the unexposed areas with a second metal. The pre-circuit is placed in an etching solution and removed after the etching solution partially etches the metal foil to undercut the second metal. The partially etched pre-circuit is then bent into a predetermined shape. The partially etched pre-circuit is then inserted into a mold cavity so that at least one surface of the circuit structure is adjacent to the mold. The mold is filled with a polymer resin so that the polymer resin encapsulates at least a portion of the partially etched pre-circuit and substantially fills the undercut. The molded circuit structure is then removed from the mold and the metallic foil is further etched to complete the forming of the circuit.

摘要： An integrated lighting assembly (10) includes an injection molded housing that has a base (12) with first fastening elements (22) molded thereon, a cover (18) with second fastening elements (24) molded thereon, and a substrate (16) intermediate the base and cover. An electrical circuit (30) is formed on the substrate and a lighting element (32) is attached to the electrical circuit. A reflective cone (34, 36) surrounds the lighting element to intensify its light and direct light through a diffuser lens (28) formed on the base. A reflective wall (26) on the base reflects light emanating from the diffuser lens in a predetermined pattern. Metal for the reflective surface and electrical circuit is deposited in a single operation. The base and cover are connected to the substrate by living hinges. When the cover is folded onto the base, the first and second fastening elements snap together to form a three dimensional lighting assembly.
