Tomas Bergsten has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11477878
    Abstract: A PCB structure and a method and apparatus for forming the PCB structure are disclosed. The PCB structure further includes a metal plate configured between a first PCB and a second PCB by soldering. Therefore, the PCB structure is easy to be produced and the feasibility can be improved with a cheap solution.

  • Patent number: 10201098
    Abstract: The embodiments herein relate to an apparatus and medium for selective partitioning of a via in a printed circuit board as to produce an electrically isolating portion between two electrically conducting portions in said via. The apparatus and medium implement a step of prior to drilling the hole for the via, laminating plating resist layers to the printed circuit board at a distance from each other corresponding to a desired length of the electrically isolated portion of the via. After drilling, copper is added to selected portions of the interior of the via in two different processing steps followed by a step of removing undesired copper as to produce the electrically isolating portion.

  • Patent number: 10193206
    Abstract: The present invention relates to a microwave signal transition component (1) having a first signal conductor side (2) and a second signal conductor side (3). The signal transition component (1) is arranged for transfer of microwave signals from the first signal conductor side (2) to the second signal conductor side (3). The transfer component (1) comprises at least one, at least partly circumferentially running, electrically conducting frame (4), a dielectric filling (5) positioned at least partly within said conducting frame (4), at least one filling aperture (6; 6a, 6b) miming through the dielectric filling, and, for each filling aperture (6; 6a, 6b), an electrically conducting connection (7; 7a, 7b) that at least partly is positioned within said filling aperture (6; 6a, 6b). The present invention also relates to a method for manufacturing a microwave signal transition component according to the above.

  • Patent number: 8553428
    Abstract: A component for mounting on a PCB, intended to support an electronics component, with an extension in the longitudinal, lateral and vertical directions. The component has a first and a second main surface, the second main surface being intended for mounting on the PCB. The component is made in a non conducting material, with a first layer of conducting material arranged on its first main surface, the conducting layer being connected to a conducting layer on the second main surface of the component by electrically conducting means. The component's extension in the vertical direction is smaller than its extension in either the longitudinal or lateral direction.
