Abstract

A magnetic stand for a tablet device is disclosed. The magnetic stand is configured to rigidly hold a portion of the tablet device in place and to shield the magnetic field from adversely affecting nearby devices susceptible to strong magnetic fields. The shielding portion of the magnetic stand allows for significant increases in magnetic field strength when compared to similarly configured, unshielded products.

Claims

1. A multilayer printed circuit board (PCB) arranged to distribute alternating current (AC) for a power supply PCB, the multilayer PCB comprising:

ground layers disposed on opposing surfaces of a dielectric medium that is disposed within a volume defined by the ground layers and radio-frequency (RF) shielding; and

the RF shielding configured to provide an RF shield for at least one conductive layer that is located between the ground layers and arranged to carry the alternating current, wherein the at least one conductive layer is;

(i) electrically isolated from the ground layers and RF shielding, and

(ii) within the volume defined by the ground layers and RF shielding.
