Clear pictures of failed MLCC could help investigation.

I got solution to manufacturer to find out the crack of MLCC if the manufacturer need it.

It could be delamination of the layered material of the MLCC caused by thermal shock or a component fabrication defect. For more on MLCC cracks: https://www.avx.com/docs/techinfo/CeramicCapacitors/cracks.pdf

Thx for the replies. Acutally I am doing a process related study to see whether the process (pcb depanelling)can induce crack to an MLCC. After depanelling, I will do a thermal shock on the MLCC based on IEC 384-1, that is, five cycles of 30min at hi

Has anybody used a MLCC Capacitor called Flexicap from Syfer? They claim they can be flexed twice as much as normal MLCC Capacitors. Do they live up to their claims?

Fine crack in multi-layer ceramic capacitor (MLCC) may not be detectable by capacitance check.Could anyone out there advise which is the most appropriate method to test/detect fine crack ?

The price increase of electronic components such as MLCC has not stopped. In recent years, driven by the development of electric vehicles, industrial control and other industries, the demand for MLCC products has increased rapidly. However, the overa

True dat...it's the first thing I look for on a molded part boss that splits!

I agree that this looks like knit line failure. Here are some examples of what this looks like in microsections of MLCCs ... https://www.semlab.com/mlcc-knit-line-failure/ https://www.semlab.com/knit-line-fracture-and-porosity/ https://www.semlab
