Abstract:
In a relay module device, a signal converting section transmits driving signals of switching elements when receiving input signals from an external device and sets a relationship between the input signals and the driving signals. The relationship includes a first mode in which the signal converting section transmits the driving signals to separately control one of the switching elements with respect to one of the input signals, and a second mode in which the signal converting section transmits the driving signals to concurrently control two or more of the switching elements with respect to one of the input signals.
Abstract:
A printed circuit board includes a surface and having first and second adjacent apertures. First and second electrical terminals include respective ends disposed in the first and second apertures of the printed circuit board, respective shoulders adjacent to the ends of the first and second electrical terminals and engaged with the surface of the printed circuit board, and respective insertion tabs adjacent to the shoulders of the first and second electrical terminals and located respective first and second distances away from the surface of the printed circuit board. The first and second distances are different such that the first and second insertion tabs do not touch one another.
Abstract:
A method for mounting connection pins in respective through-holes. Each pin having an anchoring part for insertion into said through-hole, a contact part to extend outside said through-hole and having a contact end for contact with the surface of another module of the electronic assembly, and a flange part to abut against said component carrier and located between said anchoring part and said contact part. A die tool has several similar recesses all adapted to receive a contact end of the contact part of a connection pin. The anchoring part of the pin is inserted in a through-hole of the component carrier, and the pin is anchored in the component carrier by exerting a force on a free end of the anchoring part of the pin while an end surface of the contact end abuts the bottom surface of similar recesses in the die tool.

A middle portion may be disposed between first and second portions and/or a middle portion may include a first middle section, a second middle section, a recessed portion disposed between the first middle section and the second middle section, and/or an aperture. The electrical terminal may include a transition portion that may be disposed between a middle portion and a second portion.
Abstract:
A connection pin for mounting in a through-hole provided in a component carrier of an electronic assembly, the connection pin comprising an anchoring part adapted for insertion into said through-hole, a contact part adapted to extend outside said through-hole, and a flange part adapted to abut against said component carrier and located between said anchoring part and said contact part. The connection pin is provided with an internal cavity, which is provided with an outer opening at a free end of the anchoring part. The contact part is provided with a protruding elongated interconnection member at a free end thereof, and the respective shapes of the interconnection member and the internal cavity are such that the interconnection member is adapted for insertion into a corresponding internal cavity of another similar connection pin. A method for producing an electronic assembly with stackable modules is also disclosed.
Abstract:
The invention provides a spacer for soldering comprising an elongate body having one end provided with a tapped hole and an opposite end provided with a transverse bearing surface having a smooth centering peg projecting therefrom, the peg has a longitudinal outer passage extending over at least a fraction of its length as far as the transverse bearing surface to enable molten solder to penetrate by capillarity as far as the transverse bearing surface. The invention also provides a module including such a spacer.

Abstract:
A thermal management system/method allowing efficient electrical/thermal attachment of heat sourcing PCBs to heat sinking PCBs using reflow/wave/hand soldering is disclosed. The disclosed system/method may incorporate a combination of support pins, spacer pads, and/or contact paste that mechanically attaches a heat sourcing PCB (and its associated components) to a heat sinking PCB such that thermal conductivity between the two PCBs can be optimized while simultaneously allowing controlled electrical conductivity between the two PCBs. Controlled electrical isolation between the two PCBs is provided for using spacer pads that may also be thermal conductive. Contact paste incorporated in some embodiments permits enhanced conductivity paths between the heat sourcing PCB, a thermally conductive plate mounted over the heat sourcing PCB, and the heat sinking PCB. The use of self-centering support pins incorporating out-gassing vents in some embodiments allows reflow/wave/hand soldering as desired.
