    摘要: A power core adapted for use as part of a circuitized substrate, e.g., a PCB or LCC. The core includes a first layer of low expansion dielectric and two added layers of a different low expansion dielectric bonded thereto, with two conductive layers positioned on the two added low expansion dielectric layers. At least one of the conductive layers serves as a power plane for the power core, which in turn is usable within a circuitized substrate, also provided. Methods of making the power core and circuitized substrate are also provided. The use of different low expansion dielectric materials for the power core enables the use of support enhancing fiberglass in one layer while such use is precluded in the other two dielectric layers, thus preventing CAF shorting problems in highly precisely defined thru holes formed within the power core.

    摘要: A method for generating multiple conductor segments within a plated through hole of a printed circuit board. The method utilizes laser light to define the segmented surfaces bounding a hole in a circuit board. Two embodiments of this method are a subtractive process and an additive process. The subtractive process starts with a plated through hole and uses a laser to removes vertical strips of the PTH conductive lining to form the multiple conductive segments. The additive process applies a seeding material to a bare hole in a circuit board, removes vertical strips of the seeding material via laser scanning, and applies an electrically conductive material to the seeded surfaces to form the multiple conductive segments.

    摘要: A method of making a circuitized substrate which involves forming a plurality of individual film resistors having approximate resistance values as part of at least one circuit of the substrate, measuring the resistance of a representative (sample) resistor to define its resistance, utilizing these measurements to determine the corresponding precise width of other, remaining film resistors located in a defined proximity relative to the representative resistor such that these remaining film resistors will include a defined resistance value, and then selectively isolating defined portions of the resistive material of these remaining film resistors while simultaneously defining the precise width of the resistive material in order that these film resistors will possess the defined resistance.

    摘要: An electronic structure including a metallic interlocking structure for bonding a conductive plated layer to metal surface, and a method of forming the electronic structure. The method provides a substrate having a metallic sheet within a dielectric layer. The metallic sheet includes a metal such as copper. An opening in the substrate, such as a blind via, is formed by laser drilling through the dielectric layer and partially through the metallic sheet. If the opening is a blind via, then the laser drilling is within an outer ring of the blind via cross section using a laser beam having a target diameter between about 20% and about 150% of a radius of the blind via cross section. A surface at the bottom of the opening, called a “blind surface,” includes a metallic protrusion formed by the laser drilling, such that the metallic protrusion is integral with a portion of the blind surface. The metallic protrusion includes the metal of the metallic sheet and at least one constituent element from the dielectric layer. The metallic protrusion is then etched to form a metallic interlocking structure that is integral with the portion of the blind surface. The metallic interlocking structure includes discrete metallic fibers, with each metallic fiber having a curved (or curled) geometry. Each metallic fiber has its own unique composition that includes the metal, at least one constituent element of the dielectric layer, or both.

    摘要: Disclosed is a parallel processor packaging structure and a method for manufacturing the structure. The individual logic and memory elements are on printed circuit cards. These printed circuit boards and cards are, in turn, mounted on or connected to circuitized flexible substrates extending outwardly from a laminate of the circuitized, flexible substrates. Intercommunication is provided through a switch structure that is implemented in the laminate. The printed circuit cards are mounted on or connected to a plurality of circuitized flexible substrates, with one printed circuit card at each end of the circuitized flexible circuit. The circuitized flexible substrates connect the separate printed circuit boards and cards through the central laminate portion. This laminate portion provides XY plane and Z-axis interconnection for inter-processor, inter-memory, inter-processor/memory element, and processor to memory bussing interconnection, and communication. The planar circuitization, as data lines, address lines, and control lines of a logic chip or a memory chip are on the individual printed circuit boards and cards, which are connected through the circuitized flex, and communicate with other layers of flex through Z-axis circuitization (vias and through holes) in the laminate. Lamination of the individual subassemblies is accomplished with a low melting adhesive that is chemical compatible with (bondable to) the per fluorocarbon polymer between the subassemblies in the regions intended to be laminated, and, optionally, a high melting mask that is chemically incompatible with (not bondable to) the per fluorocarbon polymer between the subassemblies in the regions not intended to be laminated. The subassembly stack is heated to selectively effect adhesion and lamination in areas thereof intended to be laminated while avoiding lamination in areas not intended to be laminated.
