emI-caused eOs sources in
Automated equipment
electrical overstress causes damage to sensitive
components, including latent damage. a signifi-
cant source of eoS is high-frequency noise in au-
tomated manufacturing equipment. This article
analyses sources of such noise, how it affects com-
ponents and how to mitigate this problem.

Localized Contamination
Can Cause big problems
in today's electronics manufacturing environment,
assemblers continue to overlook areas of localized
contamination that are capable of causing product
failures. This article talks about a case study involv-
ing a visible white residue and dendritic growth in
a connector area, and the analysis done to deter-
mine its cause and implications.

Acceptance testing Of
Low-Ag reflow solder Alloys
The electronics industry has seen an expansion of
available low-silver pb-free alloys for wave solder-
ing, miniwave rework, bga and cSp solder balls,
and, more recently, solder pastes for mass reflow.
This article discusses test protocols that can be
used for assessing new Sn-ag-cu, Sn-ag, and Sn-
cu alloys for general use in electronics.
