Printed circuit board assembly
First Claim
1. A printed circuit board (PCB) assembly comprising:
- a plurality of components in said PCB assembly having two sets of different thermal properties over an operating range of said PCB assembly;
a first component set having heat generating properties;
a second component set having heat dissipating and magnetic properties;
means for thermally linking said first component set to said second component set whereby heat generated by at least one component from said first component set is dissipated by at least one component from said second component set.

Abstract
A PCB assembly (1) in this case a DC-DC converter comprising a single layer board (2), mounts power semi-conductor devices forming high heat generating components (3) and various cores of magnetic material forming heat dissipating components (4). Tracks of heat conductive coupling material (6) lie above or below each heat generating component (3) and project into one of the heat dissipating components (4) and beside the others. In one embodiment, the heat generating components (3) are housed within a heat dissipating component (3). In another PCB assembly, there is an additional plug-in PCB which may itself carry heat generating components (3) or only heat dissipating components (4). In the latter case, the heat generating components (3) are mounted on the PCB assembly below the additional plug-in PCB.
