Abstract
An assembly carrying a radioisotope power source for attaching to a printed circuit board. The assembly comprises an integrated circuit package carrying an integrated circuit, the integrated circuit package having first contacts on a lower surface thereof, the integrated circuit requiring connection to a power source, a power source package defining a cavity therein for carrying the radioisotope power source, the power source package having second contacts on an upper surface thereof contacting the first contacts and having third contacts on a lower surface thereof for contacting fourth contacts on the printed circuit board, the power source package having conductive vias extending from the second contacts on the upper surface of the power source package to the third contacts on the lower surface of the power source package, one or more of the vias having a fan-in segment, a fan-out segment and a substantially vertical segment therebetween, and electrical signals passing between the integrated circuit and the printed circuit board through the conductive vias and power passing from the radioisotope power source into the integrated circuit through one or more of the substantially vertical segments and the fan out segments.
