Abstract:
Method for providing a conductive pattern (5) on a plastic component (2) having one or more not-flat areas (3a), comprising providing the conductive pattern on a mainly flat carrier (4), the conductive pattern comprising, for each area (3b) which corresponds to such non-flat area of the plastic component, a pattern area having an extendable shape or design. Next, putting the carrier, including its conductive pattern and one or more extendable sub-patterns, into or onto a mold (1) which is arranged for molding the plastic component. Finally, performing a molding operation in which, in any order, the plastic component is formed and the carrier is, at least partly, shaped in accordance with any not-flat area of the component, the relevant sub-pattern being stretched in accordance with that not-flat area. The extendable sub-pattern may have, at least partly, e.g. a meandering form or the form of an extendable grid.
Abstract:
An illumination assembly (10) includes a compliant substrate (30) comprising a first and second electrically conductive foil (32,36) separated by an electrically insulating layer (40). The insulating layer includes a polymer material (43) loaded with particles (42) that enhance thermal conductivity of the insulating layer. A plurality of LED dies (20) are disposed on the first conductive foil (32).

In a circuit board-connecting portion 10, a first connecting portion 15 and a second connecting portion 20 are disposed in facing relation such that first conductors 14 contact second conductors 19, and also a first substrate 12 and a second substrate 17 are fixed to each other by an adhesive 22. The first connecting portion 15 has rigid members 24 provided at a reverse surface 12B of the first substrate 12 which is a soft substrate, and the rigid members 24 are disposed along a direction of a thickness of the first substrate 14, and are provided at positions corresponding to at least parts 14A of the first conductors 14.
Abstract:
Die Erfindung betrifft einen Schaltungsträger (3) für eine elektrische Schaltung, insbesondere in der Art einer wenigstens teilweise flexiblen Leiterplatte. Der Schaltungsträger (3) weist elektrische, elektronische o. dgl. Bauteile (2), wie einen Elektromotor (2a), Schalter (2b), Widerstand, Kondensator, Spule, IC, Steckanschluß o. dgl. auf. Weiter besitzt der Schaltungsträger (3) Leiterbahnen zur elektrischen Verbindung der Bauteile (2) sowie Kontaktflächen (5) zur elektrischen Kontaktierung der Bauteile (2). Die Kontaktfläche (5) ist wenigstens teilweise in der Ebene des Schaltungsträgers (3) freigeschnitten, derart daß die Kontaktfläche (5) eine Flexibilität in eine außerhalb der Ebene (6) des Schaltungsträgers (3) verlaufende Richtung aufweist, insbesondere in der Art einer Kontaktzunge. Ein Kontaktelement (8) zur elektrischen Kontaktierung des Bauteils (2) liegt mit einem Anpreßdruck derart an der Kontaktfläche (5) an, daß die Kontaktfläche (5) aus der Ebene (6) des Schaltungsträgers (3) ausgelenkt ist.
Abstract:
The invention relates to a cooling body for electric and/or electronic components, in particular printed circuit boards. The cooling body consists of a chemically uniform material, whose exterior is cross-linked and which is thus poorly or non-adhesive and whose interior can be plastically deformed and thus adapted to the contours of the components or printed circuit boards. The cooling body can be cured by thermal post-cross-linking.

Abstract:
A method and an apparatus for providing a planar and compliant interface between a semiconductor chip (120) and its supporting substrate to accommodate for the thermal coefficient of expansion mismatch therebetween. The compliant interface is comprised of a plurality of compliant pads (110) defining channels (117) between adjacent pads. The pads are typically compressed between a flexible film chip carrier (100) and the chip. A compliant filler (170) is further disposed within the channels to form a uniform encapsulation layer having a controlled thickness.
Abstract:
The invention relates to a method for producing micro-openings in semi-finished products (300) for printed boards using prefabricated elements (200) consisting of several layers of electrically conductive materials (21, 22) and dielectrics (20). According to said method micro-openings are embossed in dielectrics and/or electrically conductive materials and the embossed micro-openings are cleaned using plasma or by means of wet-chemical methods.
