Title: BOND TEST APPARATUS AND METHOD
Abstract:
In one aspect, a bond test apparatus 200 comprises a test tool 40, a stage 80 for mounting a bond for testing, and a drive mechanism 60 comprising a voice coil. The voice coil is coupled to either the stage or to the test tool and is configured to provide relative movement between the stage and the test tool such that the bond applies a test force to the test tool. In another aspect, a bond test apparatus 200 comprises a test tool 40, a stage 80 for mounting a bond for testing, a drive mechanism 60, a velocity sensor 90 configured to sense an instantaneous relative velocity between the stage 80 and the test tool 40, and a controller 1 10 configured to control the drive mechanism 60 in response to a signal from the velocity sensor 90. In a further aspect, a bond test apparatus 300 comprises a test tool, a stage 800 for mounting a bond for testing, a drive mechanism 600 configured to apply a driving force to the stage or the test tool, and a retarding mechanism 160 coupled to the stage or the test tool and configured to apply, in response to relative movement between the stage and the test tool, a retarding force opposing the driving force. Methods of performing a bond test are also provided.
