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 ?

Hello Graham, There are no simple answers to your questions but I will be giving a virtual talk covering the reasons for vacuum reflow with void data and unintended consequences in a few weeks at the SMTA joint Space Coast - Atlanta Chapter conference.
