CHAPTER 10 PROACTIV
OVERVIEW
Introduction ProActiv™ is an active squeegee module. The ProActiv mount assembly (which
is similar to the standard squeegee mount and shares common functionality and
construction), houses the active squeegees. The difference is apparent when
using ProActiv during a print stroke, the squeegee blade is activated, this
provides additional forces in the print direction; it modifies the rheology of the
solder paste increasing its fluidity.
