Abstract:
A connector (12) for connection to terminals (18) of an integrated circuit. The connector consists of a dielectric substrate (40) having a first side and a second side. The connector has wire bond terminals (50) which are attached to the first side of the substrate and configured to receive wire bonds connected to a first set of the terminals of the integrated circuit. The connector also has solder bump terminals (60), attached to the second side of the substrate so as to be insulated from the wire bond terminals, the solder bump terminals being configured to be coupled via solder balls (64) with a second set of the terminals of the integrated circuit.
Abstract:
In accordance with the various embodiments disclosed herein, electrical connector footprints, such as printed circuit boards, is described comprising one or more of signal traces that each include a first section that extends parallel to the linear array direction and a second section extends in a direction that is different than the linear array direction.
Abstract:
A universal serial bus hybrid footprint design is described herein. The design includes an outer row of one or more surface mount technology (SMT) contacts and an inner row of one or more printed through holes (PTH). The hybrid footprint design enables a data through put of at least 10 Gbps.
Abstract:
A circuit board (10) mounted on a marking material receptacle and having a storage device for storing data relating to a marking material for print, said circuit board (10) comprising a plurality of terminals (21-27) arranged on said circuit board (10) in a single direction and connected to the storage device, wherein two of said plurality of terminals (21-27) arranged at two edges of the circuit board (10) are ground terminals (24, 27) used for determining if the marking material receptacle has been installed correctly, wherein one of said ground terminals (24, 27) receives ground potential from a printer when the marking material receptacle is installed on the printer, and another of said ground terminals (24, 27) is connected to the one of said ground terminals (24, 27) on the circuit board (10) and to be connected to a cartridge out detecting pin of the printer when the marking material receptacle is installed on the printer.
Abstract:
An electronic component module (27i) is provided with a ceramic substrate and a plurality of bonding material applying lands (3). The ceramic substrate has a rear face (27a) that is rectangular. The plurality of bonding material applying lands (3) are arranged on the rear face (27a). The plurality of bonding material applying lands (3) include outer peripheral land rows (4), each of which is arranged in a line along each side of the rear face (27a) with the exception of corner portions (7) of the rear face (27a). The plurality of bonding material applying lands (3) include corner portion inner lands (5), each of which is arranged on the rear face (27a) at a position that is shifted inwardly in a substantially diagonal direction from the corner portion (7) and is adjacent to the bonding material applying lands (3) closest to the corner portion (7) at ends of the outer peripheral land rows (4) that are arranged in lines along two sides that are connected by the corner portion (7).
Abstract:
A circuit board (10; 200) for a marking material receptacle (40, 48), comprising a storage device (30) for storing data relating to a marking material for print, a plurality of terminals (21-27; 201-207) arranged on said circuit board (10; 200), said terminals comprising a power supply terminal (22; 202) and being arranged in a plurality of rows, characterized by two ground terminals (24, 27; 204, 207) arranged for allowing a printing device (100) to determine if said marking material receptacle has been installed correctly, where said ground terminals (24, 27; 204, 207) are located at the outermost ends of a row that is different than the row that contains said power supply terminal (22; 202), and where said ground terminals (24, 27; 202, 204) are not the terminals in closest proximity to said power supply terminal (22; 202).
Abstract:
A repairable flex circuit (1), comprising: a generally flexible, electrically insulative substrate (2) having a first edge (3) thereof, and a plurality of electrically conductive circuit traces (5) arranged on the substrate. Each circuit trace has an end thereof terminating at a first connector element (8) proximate the first edge (3), and at least one second connector element (13) spaced apart from the first connector element, with each of said first and second connector elements being a plated through hole, a plated blind via, or a solder pad.
Abstract:
A printed circuit board assembly includes two-dimensional arrays of connectors (14,16) to provide significantly higher data transfer rates than typical one-dimensionally arranged connectors, without sacrificing board space. The assembly includes a plurality of connection pads (14,16) on each printed circuit board (10,12). A layer of anisotropically conducting material (26) is placed between the connection pads and the boards are held together by fastening screws (28).
