Popis: Highly integration and complexity of modern system in package (SiP) lead to critical issues of Power Integrity (PI), Signal Integrity (SI) and Electromagnetic Compatibility (EMC). In this paper, the Simultaneous Switching Noise (SSN) inducing cavity resonance is visualized via near field scan in both frequency. Furthermore, decoupling capacitors suppressing the resonance is also measured by near field scan for comparisons.
