Multilayer Capacitor Vibration Evaluation Substrate Design

The patent applies equipotentiality by creating a symmetric mounting structure where the substrate has fixed portions positioned at equal distances from the mounting region in all directions (e.g., four corners of a square substrate). This symmetric configuration ensures that vibration energy is distributed uniformly, eliminating directional biases and enabling consistent, comparable measurements across different capacitors while effectively suppressing vibration sound through balanced energy dissipation.

The patent applies asymmetry in reverse (i.e., enforcing symmetry) by designing the substrate with fixed portions at precisely equal distances from the mounting region. This symmetric arrangement creates consistent boundary conditions for vibration, eliminating the complicated variations that occur with asymmetric or irregular substrate configurations. The result is reduced sound pressure level variations and improved measurement consistency while maintaining ease of operation.

The patent applies segmentation by dividing the substrate into distinct functional regions: a central mounting region for the capacitor and multiple fixed portions positioned symmetrically around it. This segmented structure allows the substrate to maintain flexibility in mounting different capacitor types while ensuring that the fixed portions create consistent vibration modes. The clear separation between mounting and fixation functions achieves both adaptability and vibration mode stability.
