← ScienceWhich issue arises when cooling integrated circuits using phase-change materials?
A)Uniform temperature distribution is difficult✓
B)Electrical conductivity drastically decreases
C)Resonance frequencies become unpredictable
D)Coefficient of thermal expansion plateaus
💡 Explanation
Non-uniform cooling from phase-change materials results when the heat flux isn't evenly distributed because variable thermal profiles drive spatial variations. Therefore, maintaining equal interface dynamics is required, rather than uniform properties or altered electrical activity.
