SEMI G64 - Specification for Full-Plated Integrated Circuit Leadframes (Au, Ag, Cu, Ni, Pd/Ni, Pd)
This Standard was technically approved by the 3D Packaging and Integration Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on July 6, 2018. Available at www.semiviews.org and www.semi.org in November 2018; originally published in 1996; previously published August 2011.
This Specification is intended as a guideline for evaluating plating layer characteristics required by users of full-plated leadframes for plastic semiconductor packages.
Background — Full-plated leadframes have received attention in recent years as a possible solution to challenges and restrictions resulting from the effects of Pb on the environment, package reliability improvement due to the P.P.F. process, lead coplanarity on fine-pitched leadframes, and lead bridges with solder plating.
The specification and test procedures detailed in this Document apply to full-plated leadframes.
Units — SI units are used in this Document.
