Ink immersion test for implemented parts (dye and pry)
Introducing a test that allows for the observation of fracture and delamination layers by permeating coloring liquids and fluorescent liquids!
We would like to introduce our "Dye and Pry Test for Embedded Components." For confirming the breakage and delamination of packages and embedded components, there are non-destructive testing methods (such as transmission X-ray and CT) and cross-sectional observation. However, these methods make it difficult to capture the spread of delamination in the "plane" of the broken layers. In the Dye and Pry Test, by permeating a colored or fluorescent liquid, we can observe the broken and delaminated layers. Please feel free to contact us if you have any inquiries. 【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.
basic information
【Case Study】 ■BGA: Solder balls on the substrate side - As a result of observation, many solder balls fractured on the component side, progressing from the outer circumference of the ball. ■QFP: Solder joint on the substrate side - As a result of observation, the fracture progressed from the fillet heel of the lead joint. *For more details, please refer to the PDF document or feel free to contact us.
