Abstract:
Electronic arrangement (100) comprising a component carrier (110) with a first (111) and a second (112) main surface, in which component carrier a first aperture (120, 130) is arranged, the main direction of which extends from the first main surface towards the second main surface, and an electronic component (150, 160) which is arranged and retained in the aperture. The material of the component carrier (110) has essentially at least the same thermal expansion coefficient as the electronic component (150, 160), and the component carrier (110) can be used to retain the component in the aperture (120, 130). The extent of the aperture (120, 130) is the same as the extent of the component (150, 160) in a direction running between the main surfaces (111, 112) of the component carrier at right angles to the main surfaces. The component is positioned in the carrier (110) in such a manner that the extents of the component and the aperture in said direction coincide. The invention also relates to the component carrier and a method of producing the arrangement.
Abstract:
A method for arranging one or more electronic components (100) on a carrier (200). The electronic components have a number of contact points (110) arranged on a first surface (120). The carrier has a second main surface (210) and a third main surface (220). In the carrier there are also arranged one or more first apertures (230) with a depth extending from the second main surface towards the third main surface. The method comprises the stages: arranging of connecting means (130) on the contact points, where the connecting means have a first end (140) connected to one of the contact points and a second end (150) at a distance from the contact point, arranging of the electronic components in the apertures in the carrier so that the connecting means are pointed away from the third main surface of the carrier, application of a dielectric layer (300) on the second main surface of the carrier, where the dielectric layer also covers the electronic component, exposure of the second end of the connecting means in the dielectric layer, and connection of the second end of the connecting means to circuit paths (310) arranged on the free surface of the dielectric layer.
Abstract:
Conductors extend parallel to one another in a device in the microwave range. Each conductor includes a conductive layer, a layer of a dielectric material and a ground plane. The ground planes of the two conductors are separated in the device by a core made of a dielectric material. The various layers are arranged on one another in the desired order, and a cavity is arranged in the device, extending from that layer in the first conductor which is to be connected to the second conductor, at right angles to the main direction of this layer, up to and including the layer on which the conductive layer of the second conductor is to lie. A component including a stripline conductor is arranged in the cavity, the component being arranged so that electrical contact is brought about between the conductor of the component and that layer in the first conductor which is to be connected to the second conductor. Subsequently, the conductive layer of the second conductor and its remaining ground plane and dielectric layer are arranged on the device so that the electrical contact is brought about between the conductor of the component and the conductive layer of the second conductor.
