Abstract:
A method for forming electrically conductive patterns to provide an electrically conductive path on a polymer tube is provided. The method includes the steps of establishing a polymer tube and mounting such in a displaceable and rotatable mounting that is adapted to provide both axial and rotational motion. This is followed by forming at least one channel having a predetermined pattern in the polymer tube with a focused energy beam, the channel then being filled with an electrically conductive paste or electrically conductive slurry material. The polymer tube is then heated to temperatures less than 250° C. to cure the electrically conductive paste or electrically conductive slurry material. The electrically conductive paste or electrically conductive slurry material is then covered with a polymer layer.

The invention concerns a method for producing electrically conductive patterns on a non-developable surface of an insulating substrate, and the resulting device. The invention is characterized in that it consists in: coating the non-developable surface (6) uniformly with a layer of electrically conductive material (9), which is in turn coated with a layer of protective material (10), and then, using a mobile laser head, eliminating by laser ablation the portions of said protective substance layer (10) which do not cover said electrically conductive patterns, then eliminating the portions of said electrically conductive material (9) exposed by the elimination of said portions of said protective material layer (10).

Abstract:
An electric circuit is applied to an object having a curved surface. The curved surface of the object is divided into sections, and the circuit is applied one section at a time. The circuit is formed between layers of dielectric material. The dielectric is applied by a computer-controlled device, which controls the position of a spray head and the rotation of the object, such that the spray head is held substantially perpendicular to the surface of the object at all times, and such that a controlled thickness of dielectric material can be deposited. The fine-featured circuits formed by the invention are rugged, and can be used on objects intended to be exposed to harsh environments.
Abstract:
A wiring substrate includes a base insulating film, a first interconnection formed on a top surface side of the base insulating film, a via conductor provided in a via hole formed in the base insulating film, and a second interconnection provided on a bottom surface side of the base insulating film, the second interconnection being connected to the first interconnection via the via conductor. The wiring substrate includes divided-substrate-unit regions, in each of which the first interconnection, the via conductor, and the second interconnection are formed. The wiring substrate includes a warpage-controlling pattern on the base insulating film, and has a warped shape such that when the wiring substrate is left at rest on a horizontal plate, at least a central part of each side of a plane surface of the substrate contacts the horizontal plate, with both ends of the side raised, where each of the sides extends along a second direction perpendicular to a first direction in the plane surface of the substrate.
Abstract:
A MCM system board uses a stiffener arrangement to enhance mechanical, thermo and electrical properties by incorporating an LGA compression connector in a computer system. The present designs of large scale computing systems (LSCS) in IBM use a MCM that is attached to a system board and held together by a stiffening frame. Due to the nature of the manufacturing of the system board, there can be significant gaps formed in the mounting area of the MCM between the board and the stiffener. A method is described that not only fills the void, it also, in addition promotes thermo conduction of excess heat away from the MCM and at the same time promotes enhanced electrical properties of the LGA connections of the MCM to the system board.

The present invention consists of an electrical communications device including a three-dimensional substrate and a plurality of electrical devices attached thereto. The substrate is preferably a dielectric. The electrical device is preferably of the sort needed to conduct high frequency communications, such as a microwave antenna and photonic receivers and transmitters. The electrical devices are attached to the substrate at the connection points described by the intersection of a series vias and one of the substrate surfaces. The electrical devices are attached to the substrate in numerous ways, including solder, flipped chip ball bonds, wire bonds, or a gold stud assembly. In particular, the gold stud assembly is utilized to attach the antenna to the substrate, thereby providing a predetermined air gap therebetween.
