In situ formation of Cu–Sn–Ni intermetallic nanolayer as a diffusion barrier in preplated lead frames
TL;DR: In this paper, a technique for impeding Cu outdiffusion in preplated lead frames was developed by electroplating a 3-4nm thick epitaxy-like and dense (Cu,Ni)3Sn intermetallic-compound (IMC) layer.

Epitaxy-Like Protective Layers for High-Performance Low-Cost Au/Pd/Ni Preplated Cu Alloy Leadframes
TL;DR: In this article, the performance, the crystal microstructure, and defects of preplated lead frames (PPFs) are reported, and the minimum thickness of the Pd layer with the PPF performance satisfying the industry standards.

DO22–(Cu,Ni)3Sn intermetallic compound nanolayer formed in Cu/Sn-nanolayer/Ni structures
TL;DR: In this paper, the authors conducted crystal characterization by High Resolution Transmission Electron Microscopy (HRTEM) on Cu/Sn-nanolayer/Ni sandwich structures associated with the use of Energy Dispersive X-ray (EDX) analysis.

Cu diffusion kinetics in (Cu, Ni)3Sn intermetallic compound nanolayers investigated by an Energy-Dispersive-X-ray-based permeation test
TL;DR: In this paper, the Energy Dispersive-X-ray-based permeation and oxidation test has been further developed by an improved theoretical analysis, in which chemical potential gradients rather than concentration gradients are employed.
