Crack and Failure Analysis

 

Fluorescence indicators of various types – including fluorescent penetrants, magnetic particles, and other fluorescent dyes – are commonly used to highlight cracks or defects that would otherwise be difficult or impossible to see. Here we show images made with a stereo microscope and with a Keyence digital microscope.

 

 

 

 

Next we show some electronic components that were embedded in epoxy, cross-sectioned, and polished, after which indications were highlighted with an epoxy-like dye.
