Abstract:
An instrument, commonly referred to as the "surface oxide tester", is used worldwide to monitor oxide thickness of copper rod for grading and diagnosing the production process. This article provides a deeper understanding of this test and introduces several enhancements, which dramatically increase test accuracy and repeatability with little increase in test time or complexity. A new automated instrument has been developed to incorporate these improvements and a method of comparing instruments is described.
