A printed circuit board (PCB) module comprising a unitarily formed multilayer PCB, where the multilayer PCB comprises a plurality of layers, the plurality of layers comprising interleaved conductive and non-conductive layers, a first outer surface and an opposing second outer surface, the first outer surface comprising one or more components, the second outer surface comprising one or more electrical contacts such as solder bumps, and a first embedded semiconductor die having an active side facing the first outer surface, wherein the first embedded semiconductor die comprises a wireless radio-frequency transceiver such as a Bluetooth-compliant transceiver.

Printed circuit board (PCB) module comprising an embedded radio-frequency semiconductor die

A method comprises: providing a circuit board comprising a first surface, an opposing second surface, and a ground connection; defining a shielding zone and a non-shielding zone on the first surface, one or more shielding-zone electronic components being comprised within the shielding zone; providing a groove in the circuit board, the groove extending along at least part of the shielding zone and being in-between the shielding zone and the non-shielding zone; applying an insulating encapsulation layer to cover the shielding zone, whereby the one or more shielding-zone electronic components are encapsulated; applying an electrically conductive shielding layer on top of at least part of the encapsulation layer and to the ground connection so as to electrically couple the shielding layer to the ground connection, whereby the one or more shielding-zone electronic components are electromagnetically shielded. Further, disclosed is a circuit board, and a hearing device comprising a circuit board.
