Introduction to a test that allows for the observation of fracture and delamination layers by permeating with coloring or fluorescent liquids!
We would like to introduce our "Dye and Pry Test for Implementation Components." As methods for confirming the breakage and delamination of packages and implementation components, there are non-destructive tests (such as transmission X-ray and CT) and cross-sectional observations. However, these methods make it difficult to capture the spread of delamination in the "plane" of the broken layer. In the dye and pry test, by infiltrating a coloring solution or fluorescent liquid, we can observe the breakage and delamination layers. Please feel free to contact us if you would like to make a request. 【Flow of the Dye and Pry Test】 ■ Dye immersion ■ Pry ■ Observation using optical microscopy or SEM *For more details, please refer to the PDF document or feel free to contact us.
