PULL TEST CALIBRATION DEVICE AND METHOD

摘要

A device and method permits absolute and relative calibration of a pull-test device for testing the mechanical strength of electrical bond deposits. The invention provides repeatable breaking of a test specimen such as a wire (11) indexable through an anvil (17). A test tool (12) is restrained against movement from the pull axis by a low friction support such as a roller (13). A rest (14) defines a start position. The test tool is moved against the test specimen to break the test specimen. A measuring device is provided to measure the force necessary to break the test specimen.
