Classification: CPC B  G | IPC B  G

Claim 5:
6. A method for determining a strength of a bond and/or a material present on a base using a bond tester apparatus comprising:
a force measurement module comprising a shear tool configured to apply a shear force to the bond and/or the material;
a displacement module, comprising:
a movable rigid body;
a movable member configured to movably connect the force measurement module to the displacement module to provide a displacement distance between the rigid body and the force measurement module; and
a displacement sensor configured to measure the displacement distance; and

a controller configured to:
monitor the measured displacement distance;
move the rigid body, and thereby also the force measurement module, towards the base until the shear tool comes in contact with the base to obtain a contact displacement distance;
control the displacement module to clamp the force measurement module to the displacement module such that a distance between the base and the shear tool is the contact displacement distance; and
move the rigid body, and thereby also the force measurement module, to set a shear height of the shear tool, based on the contact displacement distance;

wherein the method comprises the steps of:
monitoring, by the controller, the measured displacement distance;
moving, by the controller, the rigid body, and thereby also the force measurement module, downwards until the shear tool comes in contact with the base thereby obtaining a contact displacement distance;
controlling, by the controller, the displacement member to clamp the force measurement module to the displacement module such that a distance between the base and the shear tool is the contact displacement distance; and
moving, by the controller, the rigid body, and thereby also the force measurement module, to set a shear height of the shear tool, based on the contact displacement distance.
