Bond test apparatus and method

Abstract:

A bond test apparatus comprises a test tool assembly 200 comprising a test tool 40 configured to contact a bond during a bond test, a flexure 80 coupled to the test tool assembly, and a sensor. The sensor is configured to provide a measurement of a displacement of a first end of the flexure 80 relative to a second end of the flexure on application of a force to the flexure, and a processor is configured to receive a displacement signal from the sensor and, based on the displacement signal and optionally a known stiffness of the flexure, to determine the force on the flexure. A cartridge for a bond test apparatus, a method of measuring a force in a bond test apparatus, and a method of measuring the closing force on the jaws of a bond test tool are also provided.
