Printed circuit board with integrated shielding

A local coil arrangement for magnetic resonance applications, the local coil arrangement comprising:

• 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 in the at least one intermediate layer, wherein a contact of each termination of the second plurality of terminations is connected to a respective conductor track of the plurality of conductor tracks;
• and
• a local coil disposed on the printed circuit board, configured for magnetic resonance applications, and connected to a respective conductor track of the plurality of conductor tracks not connected to the contact of one 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,
• wherein the local coil, at least one termination of the second plurality of terminations, or the 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.

A multilayer printed circuit board comprising:
