Disclosed is a method for producing a rigid power module, comprising the following steps: a monolithic lead frame is produced; said lead frame is equipped with semiconductor components and optional passive components, and corresponding connections are bonded; the equipped lead frame is introduced into a pressing tool such that the uncovered lead frame is accessible; the lead frame is fastened within the tool by means of a mounting die; and a duroplastic compression molding material is pressed into the tool so as to envelop the equipped lead frame. Cavities are left in predetermined positions in the envelope of the power module during the enveloping process, and webs of the monolithic lead frame are cut out by means of punches that are introduced into the cavities such that electrically insulated islands of materials of the previously monolithic lead frame are created.

Die Erfindung betrifft Verfahren zum Einbauen eines Chipmoduls (3) in einen Chipkartenkörper (1). Gemäß einem ersten Aspekt der Erfindung wird das Chipmodul (3) aus einem Modulband (8) herausgetrennt, insbesondere mittels eines Stanzwerkzeugs ausgestanzt, in die Kavität (2) eines Chipkartenkörpers (1) eingesetzt und dort dauerhaft fixiert. Hierbei erfolgt das dauerhafte Fixieren des Chipmoduls (3) durch einen Zweikomponentenkleber. Eine Komponente (11) des Klebers wird in die Kavität (2) des Chipkartenkörpers (1) aufgetragen und die andere Komponente (10) auf das Modulband (8). Die beiden Komponenten kommen erst beim Einsetzen des herausgetrennten Chipmoduls (3) in die Kavität (2) in Kontakt und beginnen zu reagieren und auszuhärten. Es wird keine zusätzliche Hitze benötigt und somit erfolgt keine thermische Verformung des Chipkartenkörpers (1) und dadurch keine Beeinträchtigung der optischen Qualität der Kartenrückseite (4).

An active solder alloy, an electronic device package including the active solder alloy bonding an electronic device to a substrate, and a method of forming high-strength joints by soldering using the solder alloy. The alloy contains up to about 10% by weight of an element or a mixture of elements selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, or tantalum; between about 0.1 and 5% by weight of an element or a mixture of elements selected from the group of the lanthanides (rare earths); between about 0.01 and 1% by weight of gallium up to about 10% by weight of silver; up to about 2% by weight of magnesium; and a remainder consisting of tin, bismuth, indium, cadmium, or a mixture of two or more of these elements. The alloy enables low-temperature (less than about 180° C.) soldering within relatively narrow melting ranges (less than about 10° C.).

The invention relates to a handling tool (1) for components (2), in particular electronic components (2), having a holding opening (18), to which reduced pressure (PU) can be applied and at which components to be handled can be held by reduced pressure (PU). It is provided that at least one counter-holding device (8) which projects outwards beyond the opening plane (20) in an operating position is arranged in the holding opening (18). The invention furthermore relates to a method for handling components, in particular electronic components, comprising the following steps: - sucking up a component by reduced pressure and holding the component by the reduced pressure; - supporting the component held by reduced pressure in the region of its area to which reduced pressure is applied, in such a way that said area, in particular the component, flexes concavely as seen from the reduced pressure side.

The invention relates to an electronic, in particular microelectronic, functional group and to a method for its production. The method according to the invention includes the following steps: a) coating of a mount (5a) with a non-conductive adhesive (4a); b) application of a conductor structure (3) to a subarea of the adhesive layer (4a); c) arrangement of an electronic component (1) with at least one external electrical connecting contact (2) on the adhesive layer (4a) and on the conductor structure (3), with the at least one connecting contact (2) of the electronic component (1) being brought directly into contact with the conductor structure (3), and with a part of the outer casing of the component (1) being brought directly into contact with the adhesive layer (4a). The method according to the invention allows electronic, in particular microelectronic, functional groups to be produced with care, quickly and in particular at low cost.

The invention relates to a circuit board (1) comprising at least one additional electrically conductive structure that is in the form of a round or rectangular electrically conductive wiring element (3), in particular in the form of an elongate copper element or element containing copper, that is brought into contact with copper film elements by ultrasound on at least one part on the surface on the copper film elements (4) and is integrated into the circuit board by means of a lamination process. The at least one elongate wiring element has a cross-section that is deformed by means of a specifically formed sonotrode in a contact area that is flat in parts, such that the contact surfaces are at least 20%, in particular more than 30% and more particularly more than 50% greater in a non-deformed contact surface. The wiring element is further deformed in the cross-section in an approximately triangular like manner or in a trapezoidal manner thus increasing the contact surface. Also, the elongate wiring element in brought into contact at defined intervals in a flat manner on a conductive film element that is arranged therebelow.
