Copper Wire Coating Failure Using Tribology
The surface quality of copper wire is critical in its service performance and lifetime. The micro defects in the wire surface may lead to excessive wear, crack initiation and propagation, and inadequate solderability. Proper surface treatment can remove surface defects that are generated during wire drawing, and improve the corrosion, wear and scratch resistance of the copper wire. Many applications such as aerospace and commercial airliner require copper wires to behave in a controlled manner to prevent unexpected equipment failure. Quantifiable and reliable measurements are in need in order to quantitatively evaluate the wear and scratch resistance of the copper wire surface.
Mechanical Property Broadview Mapping Tool
Seen above is an example of Nanovea’s patent pending Broadview Map Selection Tool. This new tool allows users easy selection of any location on a broad stitched surface view of the sample. Additionally, the user can select all testing parameters at each location, either for a one test or a multi-tests mapping. All locations and test parameters can be saved in easily retrievable recipes. This significant advancement provides fast & friendly Nano through Macro mechanical property studies.
