Abstract
An electronic device includes an electronic component with a mating surface. A thermal interface sheet is attached to the mating surface. A substrate carries the electronic device and includes a face. The electronic component is secured to the substrate with the thermal interface sheet positioned between the mating surface and the face. The mating surface is relatively less flat than the face and the mating surface is relatively smoother than the face.
