Tin Whisker Mitigation (TWM) by adding lead (Pb) to chip size components with pure tin (Sn) terminals. Our Sn-Pb conversion process involves both Sn-Pb plating and subsequent fusion processing to ensure that the resultant component terminations are a homogenous mixture of Sn-Pb. The AEM Sn-Pb conversion process is NOT a hot solder dip operation that introduces the risk of thermal shock to the components.
AEM Inc.'s tin / lead components are classified EAR99 under the jurisdiction of the U.S. Department of Commerce. EAR99 items are eligible for export to most end users as NLR (No License Required); however, there are certain countries and end users for which a license will be required as referenced in EAR part 736. Additionally, a license may be required if the item will be used in the design, development, production, or use in nuclear, chemical, or biological weapons, or ballistic missiles.
