Historical (view previous versions of standard)
This specification covers aluminum-1 % silicon alloy wire for semiconductor devices lead-bonding and is limited to wire of diameter up to and including 0.0020 in. (0.051 mm). The wire surface shall be clean and free of finger oils, lubricant residues, stains, and particulate matter. The elongation and breaking load shall be tested to meet the requirements prescribed. The methods in determining the wire dimensions are presented in details. Verify that the chemical requirements are satisfied by means of spectrographic analysis.
