Abstract:
Disclosed are electrical connectors and methods of assembling an electrical connector having "standard" (i.e., with electrical contacts having in-line tails), jogged (i.e., with electrical contacts having jogged tails but not connected orthogonally to another connector through a substrate), and/or "orthogonal" (i.e., with electrical contacts having jogged tails that are used in an orthogonal application) leadframe assemblies in the same connector. This provides the flexibility of using some of the available contacts in an orthogonal application and, at the same time, having remaining contacts available for routing on the midplane PCB. Though this could be done using only orthogonal leadframe assemblies, the combination of standard leadframe assemblies with orthogonal leadframe assemblies creates additional spacing between the PCB vias, so that signal traces can be more easily routed on the midplane PCB.
Abstract:
At (1502) is a digital input, at (1504) an external I/O, and at (1506) an analog or digital output, and at (1508) a test point. Also as indicated are positions for resistors: R1, R2A, R2B, R3A, R3B, R4A, R4B, R5, R6, R7; and capacitor: C1. Also shown are transistor. Q1, +5V,+3.3V, and ground. At the locations indicated are where the schematic entries in Figure 15A may be placed. A plus inside a trace denotes the +5V supply, and a minus inside a trace denotes ground. For example, if resistive components can only be placed horizontally, then padsassociated with R2B, R5, and R6 may be repositioned.
Abstract:
An interposer having a substrate composed of a flat flexible thin sheet of plastic dielectric material having a copper film laminated on one side. The substrate defines a component site in the form of a cavity in the substrate. The copper film defines a plurality of separated interconnects, each having a tab extending into the cavity formed in the substrate. An electrical component having contacts is positioned in the cavity and its contacts are bonded to the tabs. At least a plurality of the separate interconnects extend laterally beyond the substrate to define flanges. The substrate is profiled to be easily oriented in a PCB. A monolithic multi-level micropackage having a plurality of layers of copper foils laminated on flexible thin substrates processed to embed in at least one layer an interposer according to the above, the layers being bonded together by a bonding material and compressed to form a monolithic structure. The monolithic structure can have geometry to enable easy registration in a PCB. The geometry can be cylindrical with protrusions. The top layer can define connecting flanges to connect with leads on the PCB. Heat sinks can be incorporated into the structure.
Abstract:
A wiring board is characterized by comprising a first solder pulling land (13a) adjacent to the tail mounting land that is the last land in the direction in which the board is moved when an electronic componed is soldered by wave soldering and a second solder pulling land (13b) behind the first solder pulling land (13a) in the direction in which the board is moved. When a component having leads the pitches of which are narrow, represented by a QFPIC, is soldered by wave soldering, any solder bridge formed of surplus solder staying at the last lead and lands is hardly produced. The wiring board is suitable for use of solder not containing lead, thereby contributing to the environment protection.
Abstract:
A plurality of plate-like circuit component carrier packages (71) are stacked adjacent one to another with the flat faces (72, 74) thereof in contact to form a carrier package assembly (40). Each carrier package houses one or more electrical circuit component (110) coupled to electrical contacts (84, 86) on the flat faces and electrical contacts (98) or upstanding pins (424, 436) on the sides. These cooperate with those of adjacent carrier packages to electrically interconnect with the circuit components therein. A flexible, printed circuit board (50) having an array of contact sites (52) selectively interconnected by printed routing traces (54) is wrapped around the carrier package assembly. The ends of the carrier package assembly are fitted with supporting and electrically interconnecting connector blocks (22, 16). Plural carrier package assemblies are interconnectable directly, by nesting, or through intermediate connecting structures.
Abstract:
A plurality of circuit component carrier packages (71) having the same size and shape are stacked adjacent one to another with the faces (72, 74) thereof in contact to form a carrier package assembly (40) in the form of a prismatic or cylindrical solid. Each carrier package houses one or more electrical circuit components (110) and is provided at portions of the faces thereof with electrical contacts (84, 86) which cooperate with similarly located contacts on the faces of adjacent carrier packages to electrically interconnect the circuit components. The carrier package assembly is usable with a flexible, printed circuit board (50) having on one side thereof an array of contact sites (52) selectively interconnected by printed routing traces (54). Electrical contacts on the peripheral surfaces of the carrier packages are coupled with the circuit components housed therein and engage the contact sites on the circuit board when it is wrapped around the carrier package assembly.
Abstract:
An electrical contact pad (400) for electrically contacting a connector includes a first region (405a) having a first length (D1) in a longitudinal direction, and a second region (405b) having a second length (D3) in the longitudinal direction that is greater than the first length. The first region is arranged to contact a first arm of the connector and the second region is arranged to contact a second arm of the connector. The first length being smaller than the second length results in an increase in the impedance of the electrical contact pad as compared to typical contact pads which tend to correspond to low impedance regions.
