Abstract:
Connecting a capacitive measuring probe at elevated temperatures is achieved by direct attachment of metallic connecting components on a temperature substrate. A method and apparatus for a high temperature cable to circuit board connection involves a set or plurality of connecting elements that are soldered directly on the circuit board and a set or plurality of mating connecting elements that are soldered to a secondary circuit board having soldering pads for a cable.
Abstract:
A surface mountable power supply and a method of manufacturing the power supply. In one embodiment, the power supply includes: (1) a substrate having opposing upper and lower conductive layers (2) a lower electrical component having a first lead mounted on a first pad on the lower conductive layer and subject to forces capable of detaching the lower electrical component from the substrate when the power supply passes through a reflow soldering process, (3) an upper electrical component having a second lead mounted on a second pad on the upper conductive layer, (4) a solder located proximate the first lead, the lower electrical component of a sufficiently low weight such that a surface tension of a liquid state of the solder is sufficient to maintain the lower electrical component in contact with the lower conductive layer as the power supply passes through the reflow soldering process, (5) a planar magnetic device mounted on the substrate, the planar magnetic device having windings formed from a portion of conductive traces on the upper and lower conductive layers and a core disposed through apertures of the substrate and proximate the windings and (6) an inter-substrate conductive mount, coupled to the lower conductive layer, composed of a material having a melting point above a solder reflow temperature and adapted to mount the power supply to an adjacent substrate and provide a conductive path therebetween, the conductive mount including first and second compliant solder joints at interfaces of the substrate and the adjacent substrate, respectively.
Abstract:
A connector (10) for microelectronic elements includes a sheetlike body (24) having a plurality of active contacts (22) arranged in a regular grid pattern. The active contacts (22) may include several metallic projections (28) extending inwardly around a hole (27) in the sheetlike element (24), on a first major surface (32). A support structure such as a grid array of noncollapsing structural posts (23) is on a second major surface (33), and each of the posts (23) is electrically connected to one of the active contacts (22). The grid array of the posts (23) and the grid array of active contacts (22) are offset from one another so that an active contact (22) is surrounded by several posts (23). The posts (23) support the sheetlike element (24) spaced away from a substrate (41) to which the posts (23) are attached. A microelectronic element (45) having bump leads (46) thereon may be engaged by contacting the bump leads (46) with the active contacts (22), and deflecting the sheetlike element (24) between the bump leads (46) on one side and the posts (23) on the other side.
Abstract:
A thermal management system for an electrical component includes a printed circuit board (PCB) capable of receiving the electrical component on a first side of the PCB. An elongate member has one end attached to a second side of the PCB, and another end disposed away from the PCB. The elongate member also has an open interior that facilitates fluid communication between the two ends. One of the ends defines an at least partially closed boundary on the PCB. The PCB includes an aperture disposed therethrough proximate the boundary such that fluid communication is facilitated between the first side of the PCB and the second side of the PCB, and along at least a portion of the elongate member.
Abstract:
Die Erfindung bezieht sich auf eine drahtbeschriebene Leiterplatte oder Platine (1) mit geätzten Leiterbahnen (2) sich in der Leiterplatte oder Platine zwischen Anschlussstellen (4) erstreckenden Leitungsdrähten (6). Um derartige Leiterplatten zu verbessern, ist erfindungsgemäß vorgesehen, dass zumindest einer der Leitungsdrähte (6) einen rechteckförmigen oder quadratischen Querschnitt aufweist.
Abstract:
Multiple small conductive and flexible hollow rings (10), each of which is made from a pliable material, provide a flexible connection medium for use between a substrate (8) and a microelectronic device package (4). Each ring is soldered to both the substrate and the device. A portion (20, 22) of the sidewall of each ring is not soldered thus insuring that at least part of the ring stays flexible. The rings accommodate elevation differences on a substrate and electronic device package. They also provide a vibration resistant and flexible joint.
