Abstract
A dispensing apparatus for applying a pulsed thin stream of flux to a surface such as a printed circuit board. The stream of flux is pulsed at a high rate to apply a thin layer of flux on the surface. The dispensing head consists of multiple orifices for applying the flux to the board. The streams of flux are angularly disposed and a pan is positioned for capturing flux which passes by the board. The board is conveyed by the dispensing head. Controls are incorporated for board sensing and identification, application width selection, precise pressure control, fluid flow monitoring and system safety conditions.
