PCBA with point field detector and magnetic shielding arrangement located on the same side of a conductor

摘要

An electrical device includes an electrical conductor and a printed circuit board assembly (PCBA). The PCBA includes a planar substrate having first and second primary surfaces. The second primary surface is adjacent to the electrical conductor. A dot field detector is mounted on the first primary surface. A magnetic shielding assembly is constructed of a magnetic material, e.g. B. with a relative magnetic permeability of about 100-1000. The magnetic shield assembly is mounted on or disposed on the first and / or second primary surfaces of the planar substrate and includes first and second flux shield portions surrounding the dot field detector. The dot field detector and the magnetic shielding assembly are located on the same side of the electrical conductor with respect to each other.
