Circuit board assembly and radio unit comprising the same

Abstract

A circuit board assembly (1), comprising a first circuit board (10) and a second circuit board (20) which are electrically connected with each other, and a monolithic substrate (30) configured for supporting a power component and comprising a first contact surface (31) that is fixedly connected to and forms a thermal contact with the second circuit board (20), the circuit board assembly being characterized in that, the substrate (30) further comprises a second contact surface (32) that is fixedly connected to the first circuit board (10) and forms a thermal contact with the first circuit board (10) so that the substrate functions as an extension of the first circuit board to support the second circuit board. A radio unit comprising a circuit board assembly (1) is also disclosed.
