Push plate, mounting assembly, circuit board, and method of assembling thereof for ball grid array packages
Abstract
A push plate that includes springs in the form of cantilever flexures and an inspection window is disclosed. The push plate provides a known, uniform, down force and minimal torque to a package to be tested. The cantilevers have a known, calculable down force producing stiffness. The window provides for viewing of the package during testing.
