Any one has experience over solder voids in oscillator capacitor joint could result in high phase noise during the digital performances test? The noise signal was gone after solder touch up. What could be the root cause of the high phase noise?

I haven't experienced this problem, exactly, but I have had issues with noise in digital circuits that appear to have gone away with touch up. The problem was that the customer blamed the noise issue on the solder quality, and he pointed to the fact

This paper explores new advances in the reflow soldering process including vacuum technology and warpage mitigation systems. The first topic for discussion will be the implementation of a vacuum process directly in a conventional inline soldering system. The second topic presented is the mitigation of warpage on substrates or wafers.

Pockets of gas, or voids, trapped in the solder interface between discrete power management devices and circuit assemblies are, unfortunately, excellent insulators, or barriers to thermal conductivity. This resistance to heat flow reduces the electrical efficiency of these devices, reducing battery life and expected functional life time of electronic assemblies. There is also a corresponding increase in current density (as the area for current conduction is reduced) that generates additional heat, further leading to performance degradation.
Covering the industrial chain of power semiconductor materials, chips, modules, equipment and other industries, dozens of enterprises from home and abroad participated in the exhibition. This series of products can control the welding cavity rate of
