Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This
includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.
