Abstract
A method and apparatus is presented for gaining socket testability through the use of a capacitive interposer engineered to create capacitive coupling between signal nodes of a circuit assembly that the tester has access to and nodes of the socket that would not otherwise have any coupling to a testable signal node of the socket. Generally, coupling capacitance is engineered into the interposer by trace and via routing between the signal node of the socket and a location in close proximity to the inaccessible socket node such that their proximity to each other couples them together.
