Abstract
A method for detecting an endpoint during removal of material from an electronic device includes while removing material from an electronic device-under-test (DUT) using a tip driven by a spindle, applying an input signal to the DUT via the tip and using an output signal received from one of the DUT and a mounting plate to which the DUT is attached to determine an endpoint for removal of material.
