摘要:
A radio frequency (RF) device (or “tag”) for containing specific information relating to a particular good being shipped from one location (e.g., warehouse) to another (e.g., customer). The device includes a circuitized substrate (e.g., a printed circuit board), a semiconductor chip, an antenna and a power regulator, and is designed in one embodiment to be partly inserted within a good (e.g., a cardboard box) containing one or more of the goods being shipped and tracked. Alternatively, the device may be attached by other means (e.g., adhesive). A shipper can simply track the goods containing such devices using wireless communication devices (e.g., satellites) to quickly and readily ascertain the specific location of the goods at any time as well as the appropriate desired information relating to such goods (e.g., quantity, weight, type, etc.).
摘要:
A circuitized substrate comprising a first layer comprised of a dielectric material including a low moisture absorptive polymer resin in combination with a nodular fluoropolymer web encased within the resin, the resulting dielectric layer formed from this combination not including continuous or semi-continuous fibers as part thereof. The substrate further includes at least one circuitized layer positioned on the dielectric first layer. An electrical assembly and a method of making the substrate are also provided, as is an information handling system (e.g., computer) incorporating the circuitized substrate of the invention as part thereof.
摘要:
An information handling system (e.g., computer, server, etc.) Utilizing at least one circuitized substrate assembly of robust construction and possessing enhanced operational capabilities. The substrate assemblies include a substrate having at least one opening which is substantially filled with a conductive paste prior to bonding. Once bonded, the paste is also partially located within the other opening to provide an effective electrical connection therewith.
摘要:
A circuitized substrate including a plurality of conductive and dielectric layers and also a plurality of conductive thru-holes therein for passing high speed signals, e.g., from one component to another mounted on the substrate. The substrate utilizes a signal routing pattern which uses the maximum length of each of the thru-holes wherever possible to thereby substantially eliminate signal loss (noise) due to thru-hole “stub” resonance. A multilayered circuitized substrate assembly using more than one circuitized substrate, an electrical assembly using a circuitized substrate and one or more electrical components, a method of making the circuitized substrate and an information handling system incorporating one or more circuitized substrate assemblies and attached components are also provided.
摘要:
A method for testing opening patterns in an active area of a PCB wherein two arrays of test patterns of apertured pads are analyzed following drilling therethrough in accordance with a specified manner. Specifically, the outer patterns are first tested and if failure results in one or more of said patterns, an inner array of patterns closer to the active area are then tested and, significantly, only the respective test pattern nearest the associated array of openings is used to determine whether said array of openings meets the designated spacing criteria.
摘要:
A multilayered PCB including two multilayered portions, one of these able to electrically connect electronic components mounted on the PCB to assure high frequency connections therebetween. The PCB further includes a conventional PCB portion to reduce costs while assuring a structure having a satisfactory overall thickness for use in the PCB field. Coupling is also possible to the internal portion from these components. Methods of making these structures have also been provided.
摘要:
An electronic package and information handling system utilizing same wherein the package substrate includes an internally conductive layer coupled to an external pad and of a size sufficiently large enough to substantially prevent cracking, separation, etc. of the pad when the pad is subjected to a tensile pressure of about 1.4 grams per square mil or greater.
摘要:
A circuitized substrate assembly and method for making same wherein the assembly includes individual circuitized substrates bonded together. The substrates each include at least one opening, only one of which is substantially filled with a conductive paste prior to bonding. Once bonded, the paste is also partially located within the other opening to provide an effective electrical connection therewith.
摘要:
A method of making a circuitized substrate in which a commoning layer is used to form multiple, substantially vertically aligned conductive openings in a multilayered component such as a laminate interposer for coupling a chip to a printed circuit board or the like. The structure, including such a chip and circuit board is ideally suited for use within an information handling system.
