Abstract
A compact tension testing apparatus for determining the peel strength of a circuit line or film bonded to a substrate. A force gauge is mounted on an apparatus using low friction air bearings to allow the force gauge to self-align with the peeling location of the circuit line or film, thereby providing essentially orthogonal positioning relative to the substrate.
Claims11
An apparatus for measuring the peel strength of a material bonded to a substrate, comprising:
- a gripper clamp for grasping a material bonded to a surface of a substrate positioned in an x-y plane;
- a force gauge attached to a z-axis displacement system and coupled to the gripper clamp, wherein a displacement of the z-axis displacement system causes the material to peel away from the substrate, wherein the z-axis displacement system comprises a movable member for supporting the force gauge, and a system for displacing the movable member along the z-axis;
- and
- x and y-axis displacement systems attached to the z-axis displacement system for providing self-aligning orthogonal positioning of the force gauge relative to a release point of the material as the material is peeled away from the substrate;
- wherein the x-axis displacement system comprises a plurality of air bearing slides, a bridge, and a plurality of air bearings for supporting the bridge on the plurality of air bearing slides.

An apparatus for measuring the peel strength of a material bonded to a substrate, comprising:
- a gripper clamp for grasping a material bonded to a surface of a substrate;
- a force gauge attached to a first displacement system and coupled to the gripper clamp, wherein a displacement of the first displacement system relative to the substrate causes the material to peel away from the substrate;
- and
- second and third displacement systems attached to the first displacement system for providing self-aligning orthogonal positioning of the force gauge relative to a release point of the material as the material is peeled away from the substrate.
