    Abstract: A printed circuit has a creep suppressor and a stack of metallization layers separated by electrically insulating layers. A metallization layer arranged above the insulating layer at least partially covers a cavity formed in the latter's top face. Prepreg arranged directly on the insulating layer below the metallization layer bonds the layers together. A magnetic core is housed in the cavity leaves at least a five micrometer gap between the cavity's vertical walls and roof and the core's facing vertical and top faces. During stack assembly, the creep suppressor prevents prepreg from flowing, by creep, into the cavity until it contacts more than 20% of the core's top face.
