  • Patent number: 10522279
    Abstract: Disclosed are apparatus and methods for embedded high voltage transformer components. Industrial applications require transformers that provide high voltage isolation. The laminate materials used for fabricating Printed Circuit Boards (PCB) are very good insulators and PCB transformers can provide higher voltage isolation than traditional wire wound devices. There are a variety of PCB laminate materials with different properties for voltage breakdown. FR-4 laminate is commonly used and has voltage breakdown properties exceeding 10 kV/mm. To produce PCB transformers with breakdown voltages exceeding 5 kV, it is beneficial to use laminate with much higher breakdown voltages. Generally, the materials with high breakdown voltage cost more. High voltage isolation can be achieved at a moderate cost by mixing low cost FR-4 laminate with high voltage dielectric materials.

  • Patent number: 10453605
    Abstract: A first layer on a substrate includes an insulator material portion adjacent an energy-reactive material portion. The energy-reactive material portion evaporates upon application of energy during manufacturing. Processing patterns the first layer to include recesses extending to the substrate in at least the energy-reactive material portion. The recesses are filled with a conductor material, and a porous material layer is formed on the first layer and on the conductor material. Energy is applied to the porous material layer to: cause the energy to pass through the porous material layer and reach the energy-reactive material portion; cause the energy-reactive material portion to evaporate; and fully remove the energy-reactive material portion from an area between the substrate and the porous material layer, and this leaves a void between the substrate and the porous material layer and adjacent to the conductor material.
