Impact of bending speed and setup on flex cracks in multilayer ceramic capacitors

Nondestructive Acoustic Testing of Ceramic Capacitors Using One-Class Support Vector Machine With Automated Hyperparameter Selection

“…If a crack occurs within the active area of the capacitor, for example cutting through a portion of the internal electrodes, the damage can be observed as a reduced capacitance. On the other hand, if a crack or delamination resides in the passive region of the MLCC or at the solder joints, the electrical operation of the component is likely to remain unaffected at first [10]. However, the damaged location may grow in size over time, leading to a reduced capacitance, open-or short-circuit [11], or deterioration of the dielectric material as moisture gets inside the capacitor [12], [13].…”
