Abstract: A supply roll stand for loading first and second supply rolls each including a core and dispensing material therefrom. The supply roll stand broadly comprises a frame, a lift support, an unwind assembly, and a transfer support. The lift support receives the first supply roll and raises the first supply roll. The unwind assembly unwinds the first supply roll as the lift support raises the first supply roll. The transfer support receives the first supply roll so that the first supply roll is transferred from the lift support. The lift support receives the second supply roll after the first supply roll is transferred to the transfer support. The transfer support dispatches the core of the first supply roll when the first supply roll is depleted of material. The unwind assembly unwinds the second supply roll when the first supply roll is depleted of material.

Abstract: Double-sided high-power modules with air cavities are disclosed. In one aspect, a module may have a metallization layer having a high-power die on a first side and other components encased in mold material on a second side opposite the first side. Conductors are provided that couple metal conductors in the metallization layer through the mold to an external surface of the mold material such that the module may be electrically coupled to a substrate such as a printed circuit board or the like. By placing components on both sides of the metallization layer, the overall x-y dimensions of the module may be reduced.
