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:
A test board (115;115') is proposed for testing electronic devices (105;105'), each one of them having a plurality of terminals (220;220') for electrically contacting the electronic device. The test board includes a support substrate (205;205'). A set of banks of electrically conductive receptacles (210;210') are arranged on the substrate each one for resting a corresponding electronic device; each receptacle (250,255;250',255') is adapted to receive a terminal of the corresponding electronic device. Locking means (225) are further arranged on the substrate for mechanically locking the electronic devices on the test board. The test board further includes assembly means (230-245) for mounting the locking means on the substrate independently of the receptacles.

Elektrogerät und Antrieb, umfassend eine elektronische Schaltung mit Leistungshalbleitern (21), wobei die Leistungshalbleiter mittels mindestens eines Federelements (22) an einen Kühlkörper (20) angedrückt sind zur Wärmeabfuhr der von den Leistungshalbleitern erzeugten Wärme an den Kühlkörper, wobei die Leistungshalbleiter auf einem Leiterplattenstück (5) angeordnet, insbesondere lötverbunden sind, wobei das Leiterplattenstück mittels eines flexiblen Bereiches (6) mit einer ersten Leiterplatte (1) der elektronischen Schaltung verbunden ist, wobei der flexible Bereich elektrische Leiterbahnen umfasst.
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).
Abstract:
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).
Abstract:
To hold an aligned state of a terminal main body (A) to a circuit board (B), stably hold a holder (27) or the circuit board installed in the holder and prevent a deformation of the terminal main body including the contact. A part (14b, 16b) of a terminal attaching part (T) enters a through hole (23) passing through a circuit board in the thickness direction thereof to restrain indents (18) and (20) from moving in a planar direction of the circuit board. A part (17a) of an engaging piece (17) is accommodated in an engaging piece accommodating groove (41) of the holder to restrain a contact (11) from moving in longitudinal and transverse directions. A part of the contact abuts on an upper surface of the holder and a part of the terminal attaching part abuts on a lower surface of the circuit board.
