This Standard was technically approved by the Assembly & Packaging Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on August 18, 2017. Available at www.semiviews.org and www.semi.org in March 2018; originally published in 1994; previously published August 2011.
This Test Method describes a procedure to determine the ionic contamination on leadframe interleafing and the contamination transferred from the interleafing to the leadframes using a water extraction method.
This Test Method is sensitive to the following ionic species:
•Na+, NH4+, K+, Cl-, NO3-, Br-, SO42-, PO43-.
