Abstract

Apparatus for electrically interconnecting a focal plane array component of infrared detectors to a second focal plane array component of electronics, such as multiplexers. First and second interconnecting members are comprised of indium bumps wherein the bumps are of generally rectangular shape and of nonparallel orientation, typically crossing at 90.degree. angles. An alternative embodiment uses bumps of generally round shape wherein one of the bumps is of a smaller surface area than the other.
