A circuit board assembly (100) includes a circuit board (10) and at least one electrical element (20). The circuit board includes a dielectric substrate (12) including a supporting surface (13), and at least one connecting part (14) formed on the supporting surface. The at least one electrical element is electrically connected to the at least one connecting part via a connecting media (28). At least one air-exhaust hole (16) extends through the connecting part and the dielectric substrate. The at least one air-exhaust hole is configured for exhausting air from the connecting media.
