vacuum reflow | 23 March, 2021

Hi, just wondering are many assemblers using vacuum reflow systems, whether they be forced air based or vapour phase type ? If so, anyone seeing any negatives caused by the vacuum with regards liquid solder being 'sucked' away from the joints in the vacuum section, or any other weird phenomena ?
