International Classification:

H01R 909

US Classification:

174261, 174255, 361772, 361809

Abstract:

Method of manufacturing a multi-layer printed circuit board adapted for reduce interfacial sheer stresses includes a laminate substrate having a top layer forming a first major surface, a middle layer having a predetermined thickness and a bottom layer forming a second major surface opposed to the first major surface. Etch resists are disposed on the first and second surfaces corresponding to reverse images of desired conductor patterns. The first and second surfaces are thereafter etched and the photoresist removed. The laminate substrate is secured via a low modules adhesive layer to a major surface of a base. The middle layer of the laminate substrate is thereafter selectively etched so as to isolate selected portions of the first and second surfaces and to define inner connect regions therebetween having a height equal to the predetermined thickness.

US Classification:

257783

Abstract:

In a method for reversible assembly of a semiconductor electronic flip-chip device to an electrical interconnecting substrate, a filled thermoplastic adhesive is interposed between an active face of the flip-chip device and a bond site on the substrate. Electrical connection is established between the flip-chip device and the substrate and, generally simultaneously, adhesive bonding between them is established via viscous flow of the filled thermoplastic adhesive above its glass transition temperature, followed by cooling of the adhesive. The adhesive can be reheated to free the flip-chip device of its adhesive bond to the substrate. The filled thermoplastic adhesive includes a low expansion filler in a binder matrix. In accordance with one aspect of the invention, the binder matrix is poly(aryl ether ketone) having the chemical formula ##STR1## where n is from 5 to 150 and R is selected from suitable divalent moieties. The filled thermoplastic adhesive can be interposed between the flip-chip device and the substrate as a preform or by other suitable method, such as syringe extrusion in a molten or viscous state.

International Classification:

B32B 900

US Classification:

428209

Abstract:

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.

International Classification:

H01L 2144

US Classification:

438678

Abstract:

A fully additive method of applying a circuit pattern to a three-dimensional, nonconductive part comprises: pretreating the surface of the part; pad-printing a surface catalyst in a solvent carrier onto the surface in the shape of a desired circuit pattern; and applying an electroless copper deposit onto the surface catalyst, thereby providing a copper layer on the surface in the desired circuit pattern shape.

Abstract:

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.
