摘要:
A circuitized substrate which includes a plurality of contiguous open segments which define facing edge portions within an electrically conductive layer to isolate separate portions of the conductive layer such that the layer can be used for different functions, e.g., as both power and ground elements, within a product (e.g., electrical assembly) which includes the substrate as part thereof. A method of making the substrate, an electrical assembly utilizing the substrate, a multilayered circuitized assembly also utilizing the substrate and an information handling system, e.g., a mainframe computer, are also provided.
摘要:
A method of making a printed circuit board in which conductive thru-holes are formed within two dielectric layers of the board's structure so as to connect designated conductive layers. One hole connects two adjacent layers and the other connects two adjacent layers, including one of the conductive layers connected by the other hole. It is also possible to connect all three conductive layers using one or more holes. The resulting holes may be filled, e.g., with metal plating, or conductive or non-conductive paste. In the case of the latter, it is also possible to provide a top covering conductive layer over the paste, e.g., to serve as a pad or the like on the board's external surface.
摘要:
A method of making a circuitized substrate which includes a plurality of contiguous open segments along a side edge portion of the at least one electrically conductive layer thereof, these open segments isolated by a barrier of dielectric material which substantially fills the open segments, e.g., during a lamination process which bonds two dielectric layers of the substrate to the conductive layer.

摘要:
A circuitized substrate in which two conductive layers (e.g., electroplated copper foil) are bonded (e.g., laminated) to an interim dielectric layer. Each of the two foil surfaces which physically bond to the dielectric are smooth (e.g., preferably by chemical processing) and include a thin, organic layer thereon, while the outer surfaces of both foils are also smooth (e.g., preferably also using a chemical processing step). One of these resulting conductive layers may function as a ground or voltage plane while the other may function as a signal plane with a plurality of individual signal lines as part thereof. An electrical assembly and an information handling system utilizing such a circuitized substrate are also provided.
摘要:
Apparatus and method for making circuitized substrates using a continuous roll format in which a layer of conductor is fed into the apparatus, layers of photo-imageable dielectric are applied to opposite sides of the conductor layer, thru-holes are formed through the composite, and then metal layers are added over the dielectric and then patterns (e.g., circuit) are formed therein. Several operations are performed in addition to these to form the final end product, a circuitized substrate (e.g., printed circuit board), all while the conductor layer of the product is retained in a solid format, up to the final separation from the continuous layer.
摘要:
A capacitive substrate and method of making same in which first and second glass layers are used. A first conductor is formed on a first of the glass layers and a capacitive dielectric material is positioned over the conductor. The second conductor is then positioned on the capacitive dielectric and the second glass layer positioned over the second conductor. Conductive thru-holes are formed to couple to the first and second conductors, respectively, such that the conductors and capacitive dielectric material form a capacitor when the capacitive substrate is in operation.
