ASTM F72-24

Annotation of standard text ASTM F72-24 :

This specification covers round drawn/extruded gold wires for internal semiconductor device electrical connections. The wires are available in four classifications, namely: copper-modified wire, beryllium-modified wire, high-strength wire, and special purpose wire. Aptly sampled wires shall be examined by test methods suggested herein, and each class shall conform correspondingly to specified requirements for chemical composition, mechanical properties (breaking load and elongation), dimension (diameter and weight), and workmanship and finish. The wires shall also undergo wire curl, wire axial twist, and wire roundness tests.
