A bond test apparatus comprises a test tool assemblycomprising a test toolconfigured to contact a bond during a bond test, a flexurecoupled 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 flexurerelative 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.

Bond test apparatus and method

A cartridge suitable for use in a bond testing machine includes a plurality of a different test tools. A rotary mechanism is provided and each of the plurality of different test tools is mounted to the rotary mechanism angularly spaced from one another. A drive unit is coupled to the rotary mechanism and is configured to rotate the rotary mechanism to move each of the plurality of different test tools to and from a use position. An air interface receives compressed air from a corresponding air interface on a positioning assembly of the bond testing machine.
