Abstract:
A method and system for connecting and using a circuit board connected to a conductive element is disclosed. The circuit board includes a backstop and a plurality of conductive traces positioned on an edge. The conductive element includes a plurality of conductive layers and a plurality of insulating layers alternately placed along the length of the conductive element. The conductive element is placed between the edge of the circuit board having the conductive traces and a clasp prior to inserting the circuit board into the clasp. The conductive element is conformed between the circuit board and the clasp. Each conductive trace contacts a conductive layer as a result of the insertion. The backstop conforms an extending portion of the conductive element to be substantially perpendicular to the circuit board. The assembled device can be used to provide charge to a plurality of electrodes on a substrate simultaneously.
Abstract:
The present invention relates generally to permanent interconnections between electronic devices, such as integrated circuit packages, chips, wafers and printed circuit boards or substrates, or similar electronic devices. More particularly it relates to high-density electronic devices.The invention describes means and methods that can be used to counteract the undesirable effects of thermal cycling, shock and vibrations and severe environment conditions in general.For leaded devices, the leads are oriented to face the thermal center of the devices and the system they interact with.For leadless devices, the mounting elements are treated or prepared to control the migration of solder along the length of the elements, to ensure that those elements retain their desired flexibility.
Abstract:
A method of retaining a solder mass to a solder-bearing article is provided and includes the steps of: (a) forming a plurality of openings in the solder-bearing article; (b) disposing a length of solder mass over at least some of the plurality of openings; and forming a plurality of solder rivets along the length of the solder mass. The solder rivets serve to retain the length of solder mass to the solder-bearing article. The solder-bearing article includes any number of different types of components where a solder mass is held thereby, e.g., leads, terminals, connectors, electromagnetic shields, etc.

Abstract:
A switching power-supply module includes circuit boards, power conversion circuit sections provided on the respective circuit boards, conductor land patterns provided with spacing therebetween along edges of the circuit boards, conductor terminals for interconnecting the conductor land patterns. The circuit boards are stacked with spacing therebetween with the corresponding conductor land patterns being aligned, and the aligned conductor land patterns are interconnected by the corresponding conductor terminals. At least one of the conductor terminals includes an interboard-connection portion for interconnecting the conductor land patterns of the circuit boards and a leg portion that extends from the interboard-connection portion in the stacking direction of the circuit boards and that defines an external-connection portion, and the other conductor terminals each function as an interboard-connection dedicated terminal for providing connection between the circuit boards.
Abstract:
A multi-chip module comprising a low-temperature co-fired ceramic substrate having a first side on which are mounted active components and a second side on which are mounted passive components, wherein this segregation of components allows for hermetically sealing the active components with a cover while leaving accessible the passive components, and wherein the passive components are secured using a reflow soldering technique and are removable and replaceable so as to make the multi-chip module substantially programmable with regard to the passive components.
Abstract:

The plasma display device includes a plasma display panel having a display area, on which images are displayed; a chassis base coupled to a back surface of the plasma display panel; at least one circuit board, on which at least one electronic element for driving the plasma display panel is mounted, the circuit board having a conductive portion and at least one coupling hole to be coupled to the chassis base by a bolt member penetrating the coupling hole; and at least a conductive member which contacts the conductive portion and the bolt member in the coupling hole.
Abstract:
A holding element with a holding clip for holding a carrier board is soldered freestanding to a printed circuit board (PCB). The holding element has first and second holding arms that extend from a supporting region and form a receiving region therebetween. The first holding arm is connected to a first leg and the second holding arm is connected to a second leg. The first and second legs each have a base in an end region. At least one of the legs has a curved surface in the region of the base so that the holding element can be soldered to the PCB. The holding element being made of a strip material, and the first and second holding arms each having an outward bend forming a transition into the first and second legs, respectively.

Devices and methods are disclosed for reinforcing substrates having edge-mount connectors. In one embodiment, the device comprises a fragile substrate, a reinforcement plate bonded to the substrate, and an edge-mount connector mated with the substrate and the reinforcement plate.
Abstract:
An electronic component has a casing having a resin injecting section having at least one wall. At least one circuit board is housed in the casing, next to the resin injecting section via the wall. At least one lead terminal is provided in the casing. The lead terminal has a first end and a second end, and a middle section connected between the first and second ends. The first end of the lead terminal is connected to the circuit board in a way that the middle section of the lead terminal is provided as straddling the wall of the resin injecting section. Also provided is at least one lead wire having a third end and a fourth end. The third end of the lead wire is connected to the second end of the lead terminal in the resin injecting section. The fourth end of the lead wire is pulled out from the casing. The third end of the lead wire and the second end of the lead terminal connected to each other are embedded in resin injected in the resin injecting section whereas the middle section of the lead terminal straddling the wall of the resin injecting section is not embedded in the resin. In stead of straddling the wall of the resin injecting section, the middle section of the lead terminal may be inserted into an opening provided on the wall and connected to the circuit board.
