Printed circuit board with integrated shielding

摘要

A printed circuit board (PCB) is flat, providing a top side and a bottom side. A plurality of terminations is disposed on the top side in proximity to one end face of the PCB. Each termination has at least one contact that is connected to a respective conductor track of the PCB. The respective conductor track is connected to a respective local coil or to a contact disposed on the top side or the bottom side of a respective further termination. The local coil and/or at least one of the further terminations are disposed in proximity to the other end face. A basic shield impervious to frequencies in a magnetic resonance range is disposed on the top side and/or the bottom side, and an auxiliary shield electrically connected to the basic shield and impervious to frequencies in the magnetic resonance range is disposed on narrow sides of the PCB.

主权项

1. A printed circuit board comprising:
a top side; a bottom side; at least one intermediate layer disposed between the top side and the bottom side; a basic shield disposed on the top side, the bottom side, or the top side and the bottom side, the basic shield being impervious to frequencies in a magnetic resonance range; an auxiliary shield electrically connected to the basic shield and disposed on end faces that extend from the top side to the bottom side, the auxiliary shield being impervious to frequencies in the magnetic resonance range; and a first plurality of terminations configured for first shielded cables, the first plurality of terminations being disposed on the top side in proximity to one of the end faces; a second plurality of terminations configured for second shielded cables; and a plurality of conductor tracks that run the at least one intermediate layer, each conductor track being connected to a respective local coil configured for magnetic resonance applications and disposed on the printed circuit board or to a contact of a termination of the second plurality of terminations, wherein each termination of the first plurality of terminations has at least one contact connected to a respective conductor track of the plurality of conductor tracks, the respective conductor track extending from the at least one contact in the direction of the other of the end faces, and wherein the respective local coil, at least one termination of the second plurality of terminations, or the respective local coil and the at least one termination of the second plurality of terminations are disposed in proximity to the other of the end faces.
