Feb 12, 2001 Opti-Flux II spray fluxing system from Ultrasonic Systems, Inc. (USI) is now capable of automated, in-line selective fluxing. The operator can now apply flux to selected areas of the board or pallet fixture. The system automatically identifies the type of board by bar code, which is associated with a recipe previously entered into the menu by the operator. Setup can be programmed easily through PC-based software.
The Opti-Flux Series of spray fluxers is ideal for the precision application of flux to printed circuit boards. The spray is produced with Ultra-Spray technology, which uses a solid vibrating titanium surface rather than a nozzle to atomize the flux. The ultrasonic energy produces very small droplets of flux, which are then shaped and propelled by an Air Director. This results in a uniquely uniform rectilinear spray pattern with enough force to ensure complete through-hole flux penetration.
The system significantly improves the no-clean process by depositing the optimal amount of flux to facilitate soldering, and no more. This results in a reduction of flux residue on the board, fewer soldering defects, and less overall flux usage.
