Package removal for FBGA devices

摘要

Aspects for removing device packaging from an FBGA (fine pitch ball grid array) package are described. In an exemplary method aspect, the method includes recessing a predetermined area of the FBGA package, and exposing an integrated circuit die covered by the FBGA package. Device analysis is then performed on the exposed die. The step of recessing further includes milling the predetermined area, while the step of exposing includes chemically etching the FBGA package.
