Abstract:
A method of and system (200) for manufacturing an electronic device (300, 300'), a curable conductive adhesive for use in the same, and an electronic device (300, 300') are disclosed. The method includes printing a conductive adhesive onto pads at ends of traces on a substrate (310, 360), placing one or more components (320, 340, 340', 350, 355) having a non-standard size and/or shape (e.g. circular, oval or rectangular with rounded corners) onto the pads with the conductive adhesive thereon, and after the component(s) (320, 340, 340', 350, 355) have been placed onto the pads, curing the conductive adhesive at a predetermined temperature or with light having a predetermined wavelength (band). The one or more components (320, 340, 340', 350, 355) having a non-standard size and/or shape may be an antenna (320), a sensor (340, 340') and/or a display (350, 355). The electronic device (300, 300') may further comprise one or more additional components (330, 335, 370) having a standard size and/or shape on a second subset of the pads. The additional components (330, 335, 370) may be an integrated circuit (330, 335) and/or a battery (370). The system (200) comprises a printer (220) configured to print a conductive adhesive onto pads at ends of traces on a substrate, a surface mounting (SMT) machine (230) configured to place one or more components (320, 340, 340', 350, 355) having a non-standard size and/or shape onto the pads with the conductive adhesive thereon, and a curing station configured to cure the conductive adhesive after the component(s) (320, 340, 340', 350, 355) have been placed onto the pads. The SMT machine (230) may include a nozzle head having a surface with a shape identical to or configured to match a shape of the component (320, 340, 340', 350, 355) it picks up.
Abstract:
A flexible multilayer construction (100) for mounting a light emitting semiconductor device (200) (LESD), includes a flexible dielectric substrate (110) having an LESD mounting region (120), first and second electrically conductive pads (130, 140) disposed in the LESD mounting region for electrically connecting to corresponding first and second electrically conductive terminals of an LESD (200) received in the LESD mounting region, and a first fiducial alignment mark (150) for an accurate placement of an LESD in the LESD mounting region. The first fiducial alignment mark is disposed within the LESD mounting region.
Abstract:
Die Erfindung schlägt ein Verfahren zum Herstellen einer elektronischen Baugruppe vor. Ausgangspunkt ist eine metallisch leitende Folie, die mindestens einseitig nicht beschichtet ist. Auf dieser Folie werden elektronische Bauteile mit ihrer aktiven Seite der Folie zugewandt befestigt, insbesondere verklebt. Die Verklebung geschieht dadurch, dass nur an den Stellen, wo die elektronischen Bauteile befestigt werden sollen, Klebstoff aufgebracht wird. Der Klebstoff kann entweder auf die Folie oder auf die elektronischen Bauteile aufgebracht werden. Die Bauteile werden dann gegen die Folie angedrückt und verklebt. Anschließend wird die Folie mit den verklebten Bauteilen auf der Seite der Bauteile mit einem Leiterplattenträger laminiert. Erst dann wird auf der gegenüberliegenden Seite eine Leiterbahnenstruktur hergestellt, und die Anschlüsse der elektronischen Bauteile werden durch die leitende Folie hindurch kontaktiert. Auf die strukturierte leitende Folie können weitere Ebenen zur Kontaktierung aufgebracht werden.
Abstract:
The invention relates to a method for the production of an electronic assembly (21), particularly for high-frequency applications, comprising at least one electronic component (9) that is mounted on a printed circuit board (45), and at least one conductor structure (15, 25), by means of which the at least one electronic component (9) is contacted. For this purpose, the at least one electronic component (9) is mounted on an insulating layer (5) of a conductive foil (1). The conductive foil (1) having the at least one electronic component (9) mounted thereon is laminated onto a printed circuit board carrier (13). The structuring of the conductive foil (1) and the contacting of the at least one electronic component (9) forms a conductor structure (15). Soldering points (35) are provided to through-platings (33), which are configured in the electronic assembly (21) and lead to the bottom of the electronic assembly (21), and are connected to the conductor structure (15, 25).
Abstract:
This publication discloses an electronic module and a method for manufacturing an electronic module, in which a component (6) is glued (5) to the surface of a conductive layer, from which conductive layer conductive patterns (14) are later formed. After gluing the component (6), an insulating-material layer (1), which surrounds the component (6) attached to the conductive layer, is formed on, or attached to the surface of the conductive layer. After the gluing of the component (6), feed-throughs are also made, through which electrical contacts can be made between the conductive layer and the contact zones (7) of the component. After this, conductive patterns (14) are made from the conductive layer, to the surface of which the component (6) is glued.
Abstract:
Systems and methods are provided for the embedding of thin chips. A well region is generated in a substrate that includes a conductive material disposed on a flexible polymer. The standoff well region can be generated by pattern the conductive material, where the thin chip is embedded in the standoff well region. A cavity can be generated in the polymer layer to form a polymer well region, where the thin chip is embedded in the polymer well region. In an example, at least two well regions can be generated in a substrate that includes a conductive material disposed on a flexible polymer. At least one of the at least two well regions can be a standoff well region.
