Analysts use two major methods for mechanical cross sectioning: potting the sample and grinding with abrasive compounds, and glass wheel cross sectioning. Potting and grinding with abrasive compounds can be performed on most any sample. Glass wheel cross sectioning requires that the die be removed from its package.

Adopting a safe system approach to road safety recognises that humans, as road users, are fallible and will continue to make mistakes, and that the community should not penalise people with death or serious injury when they do make mistakes.

06/26 · Microsectioning or Cross-sectioning is a failure analysis technique (performed during DPA) for mechanically exposing a plane of interest in a die or package for further analysis or inspection. It usually consists of sawing, grinding, polishing, and staining the specimen until the plane of interest is ready for inspection by optical or electron microscopy.

Oct 28, · Application Note for Leica EM RES102 - The surfaces of polished cross sections often show fine scratches and residues of the removed material or of the abrasive material. The artefacts are strongly material-dependent, and are mostly only detectable at higher resolutions in the scanning electron microscope. A further problem arises from the fact that the ground section mostly only has low

Academics and Regulations/. Grading System and Grade Point Average Computation. All course grades are letter grades unless otherwise specified in the class schedule. Non-Graded — Used for sections that are not graded, usually continuing education

What is Micro-Sectioning of PCB’s? A destructive technique for evaluating the quality of a PCB, micro-sectioning works by exposing a cross-sectional view of microstructure at a selective plane. This plane is normally the center of plated through holes or vias within +/-10% tolerance of accuracy of plated material thickness.

From Wikipedia, the free encyclopedia In electronics, a cross section, cross-section, or microsection, is a prepared electronics sample that allows analysis at a plane that cuts through the sample. It is a destructive technique requiring that a portion of the sample be cut or ground away to expose the internal plane for analysis.
