Also, depending on the paste, an adjusted profile can go a long way to
eliminate, reduce voiding.

Some pastes are more likely to produce voids than other pastes. Talk to your
supplier. They may know something. We use many different brands and types of
paste because of our place in the industry. We saw a sudden increase in
voids, discussed it with the paste supplier, they suggested we change paste
type, we did and the problem went away.
