The present invention involves a device for detecting a condition of a flowing fluid within a vehicle having reduced sulfur ingress. The device includes a base plate having a receiving surface and a circumferential edge and a printed circuit board disposed on the receiving surface of the base plate. The device further includes a housing having peripheral side walls attaching to the receiving surface adjacent the circumferential edge to define a peripheral interface enclosing the printed circuit board within the housing. The device further includes an adhesive material disposed at the interface to adhere the housing to the base plate. The adhesive material has a predetermined thermal expansion coefficient and a predetermined elastic modulus to reduce fluid ingress through the interface and to accommodate thermal expansions of the base plate and the housing.

A method for forming connections within a multi-layer electronic circuit board . In one non-limiting embodiment, the method includes selectively forming air bridges over portions of the circuit board and selectively collapsing the air bridges with a metallurgical bonding tool, effective to interconnect layers of the circuit board

Electrical circuit board and a method for making the same

A solderless method for assembling a semiconductor electronic flip-chip device to an electrical interconnecting substrate including the steps of forming a plurality of raised electrical contacts and plurality of contact pads. The pads correspond in number and physical location with the electrical contacts. The pads and contact mate when brought together. A quantity of plastic material is interposed between the electrical device and substrate. The plastic material is heated so that it softens and flows. The electronic device and substrate are urged together. The urging step displaces the molten plastic material from between the contacts and pads. The contacts and pads are jointed directly without any adhesive, solder or conducive filler therebetween to electrically interconnect the electronic device and substrate. The plastic material is allowed to cool whereby the electronic device and substrate are adhesively bonded together and electrically interconnected.

Solderless flip-chip assembly and method and material for same

A method of manufacturing an electronic circuit assembly that includes a number of electrically interconnected flexible films, each flexible film having a flexible electrical wiring circuit. The electrical wiring circuits are interconnected between film layers and the film layers are adhered to a molded backing structure. A first flexible film is formed with a pattern of flexible electrical wiring circuits created on at least one surface thereof. The first flexible film has a passage that provides an electrical connection through the flexible film. A second flexible film is formed with a pattern of flexible electrical wiring circuits created on a least one surface thereof. The second flexible film has an electrical interconnect feature that connects with the electrical passage on the first film and electrically connects the first film with the second film. The first flexible film is overlaid juxtaposed the second flexible film so that the passage is aligned adjacent the electrical interconnect feature. The first and second flexible films are placed within an open mold. The mold is closed and a plastic material is injected within the mold adjacent at least one surface of the first and second flexible films. The molten plastic adheres to the first and second flexible films and forms an integral backing structure. The backing structure and first and second flexible films together form the circuit assembly.

A method of manufacturing an improved multi-layer printed circuit assembly having at least two conductor patterns. The method includes providing a first layer having a first metal surface a second layer having a second metal surface. A thin flexible carrier is placed between the first and second layers. The first and second layers are attached to opposite surfaces of the carrier. The first and second metal surfaces are etched to form first and second conductor patterns. The conductor patterns form the electrical traces interconnecting components on an electronic circuit assembly. The first and second conductor patterns are electrically connected to form an electronic circuit assembly that includes electronic traces on both sides of the circuit board.

Apparatus and method for embedding conductors in a non-planar substrate

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.

Repairable flip-chip undercoating assembly and method and material for

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.

` Method for fabricating an undercoated chip electrically interconnected to a substrate. The method includes the initial step of depositing a predetermined quantity of a liquid undercoat material onto the chip or the substrate. The method continues with the step of interconnecting the chip to the substrate so as to form an electrical interconnection bond therebetween. Finally, the method concludes with the step of heating, reflowing and curing the undercoat material during or after the step of electrically interconnecting the chip to the substrate.
