  • Patent number: 9924594
    Abstract: A printed circuit board (PCB) has a first, structured metalization arranged on its top side and at least one second metalization arranged below the first metalization in a vertical direction, parallel to the first metalization and insulated therefrom. Also on the PCB top side is a bare semiconductor chip having contact electrodes connected by bonding wires to corresponding contact pads of the first metalization on the PCB top side. A first portion of the contact electrodes and corresponding contact pads carry high voltage during operation. All high-voltage-carrying contact pads are conductively connected to the second metalization via plated-through holes. An insulation layer completely covers the chip and a delimited region of the PCB around the chip, and all high-voltage-carrying contact pads and the plated-through holes are completely covered by the insulation layer. A second portion of the contact electrodes and corresponding contact pads are under low voltages during operation.
