Oil-air electrical feedthrough circuit board for high voltage generator

A medical imaging device, comprising:

• a tubular envelope of a high voltage tank;
• a printed circuit board having an oil side and an air side arranged inside the high voltage tank, wherein the oil side and the air side are contiguous regions, and wherein both the oil side and the air side are on both faces of the printed circuit board;
• a pair of mechanical seals arranged on opposing sides of the printed circuit board, wherein the pair of mechanical seals surround the oil side of the printed circuit board;
• and an end plate.

A high voltage tank, comprising:

• a pair of primary insulation bars;
• a printed circuit board arranged inside a high voltage tank having both an oil side and an air side on each of a first face and a second face of the printed circuit board, wherein the oil side and the air side are contiguous regions on each of the first face and the second face of the printed circuit board;
• a pair of O-rings arranged on either side of the printed circuit board, wherein a first O-ring of the pair of O-rings surrounds the oil side of the printed circuit board on the first face, and a second O-ring of the pair of O-rings surrounds the oil side of the printed circuit board on the second face;
• an end plate;
• and
• a tubular envelope;
• wherein the end plate and the tubular envelope comprise an outer surface of the high voltage tank;
• wherein the printed circuit board comprises a plurality of grounding clips coupled to the first face on the oil side and a pair of split grommets arranged around a circumference of the primary insulation bars;
• wherein the printed circuit board comprises a plurality of layers, wherein the plurality of layers comprises two electrically conductive outer signal layers, two electrically conductive inner signal layers, and dielectric layers separating the outer signal layers and the inner signal layers, wherein the inner signal layers of the plurality of layers electrically connects the oil side and the air side of the printed circuit board;
• wherein the printed circuit board has a surface metallization on each side, wherein the surface metallization on each side provides a surface roughness compatible to seal the pair of O-rings to each side of the printed circuit board.
