Abstract:
A low Z profile consolidated thermal module suitable for securing and removing excess heat generated by an integrated circuit (208) mounted to a printed circuit board (214) and operating in a compact computing environment is disclosed. The consolidated thermal module comprises a heat removal assembly (202, 204, 206) with a reduced footprint and disposed on a first surface of the printed circuit board and in thermal contact with the integrated circuit. A retaining mechanism (210) is disposed on a second surface of the printed circuit board and a backer plate (218) is disposed between the retaining mechanism and the printed circuit board. At least one fastener (212) secures the heat removal assembly to the backer plate and the retaining mechanism, wherein the retaining mechanism causes a substantially uniform retaining force to be applied across the backer plate, thereby minimizing an amount of torque applied to the integrated circuit.
Abstract:
Zur Herstellung einer Verbindung zwischen einer leitenden Folie und einem Plattenelement mit mindestens einer Bohrung wird vorgeschlagen, die Verbindung in der Weise zu gestalten, dass die nicht gelochte Folie mithilfe von Kontaktstiften in Bohrungen des Plattenelements eingetrieben wird. Die Kontaktstifte legen die umgebogenen Teile der Folie an die Wand der Bohrung an und verklemmen sich in der Bohrung. Die Einpresstiefe der Kontaktstifte wird dadurch begrenzt, dass das Klemmelement, aus dem sie hervortreten, an der Oberseite des Plattenelements zur Anlage kommt. Dadurch werden auch Bereiche der Folie zwischen der Oberseite der Platte und dem Klemmelement direkt verklemmt.

Abstract:
In a screen printing apparatus for contacting a lower surface of a mask plate (12) with a substrate (6) and moving a squeezee (16) in a sliding motion on an upper surface of the mask plate (12) thereby printing a paste onto the substrate, mask bend preventing members (117) are mounted on conveying rails (7) at front and rear parts of clamp members (8) clamping the substrate (6) in a Y-direction, and, at a mask separating operation after printing, the substrate is lowered while the lower surface of the mask plate (12) is supported by the clamp members (8) and the mask bend preventing members (117). Thus the mask separation can be achieved in a state where the mask plate (12) is supported from below on four sides of the substrate (6) and is thus prevented from a downward bending, and a satisfactory mask separating property can be ensured over the entire substrate (6).

A component alignment casing system (10) for connecting circuits, and a method for making or assembling the component alignment casing system is disclosed. The system has at least one surface mountable component (12) which has a plurality of exposed leads (28), a prepared component (14) which has a plurality of exposed traces (16), an alignment base (18) onto which the prepared component (14) and the surface mountable component (12) are laid, and a compressive cover (20) that attaches to said alignment base (18). The alignment base (18) has a plurality of alignment ribs (22) to isolate and align the exposed traces (16) of the prepared component (14). The prepared component (14) and the at least one surface mountable components (12) are electrically connected and attached together, preferably by soldering. The method includes laying the prepared component (14) on the alignment base (18) and ribs (22), and overlaying the surface mountable component (12), with its exposed leads (28), onto the alignment base (18) and the prepared component (14), and electrically connecting the components together, preferably by soldering, to the alignment base (18). The cover (20) is then snapped on, and supplies compressive force to assure good contact between the leads (28) of the surface mountable component (12) and the traces (16) of the prepared component (14).
