A Note From The President
"Successful spray fluxing of circuit boards for wave soldering requires, first and foremost, good flux chemistry. But good flux chemistry alone cannot guarantee soldering success. Flux must be applied to the circuit board in the proper amount and only where it is needed.
USI has achieved its position as the industry leader in wave solder spray fluxing technology because we have built a rock-solid foundation on performance and reliability."
Stuart Erickson, President, Ultrasonic Systems, Inc. |

What Our Customers Say
"We had a reciprocating nozzle fluxer and we were switching to a VOC-free fluxing process. We replaced it with a USI spray fluxing system and immediately realized improvements in flux deposition control while reducing flux consumption by 89%. I recommend USI spray fluxing systems to anyone in need of spray fluxing control."
-Bryan Spinney,
Act Electronics, Hudson MA
"Our nozzle fluxing system provided poor control over flux volume, especially with VOC free fluxes. When using No Clean Rosin Based Fluxes we required to "over flux" our circuit boards causing maintenance problems and cutting into valuable production time. We upgraded to USI's Optima Spray Fluxing System and immediately saw improved flux deposition control, a 30% reduction in flux consumption, higher yields and a virtual elimination of maintenance. I would recommend USI Spray Fluxing Systems to improve yield and production throughput."
-Marcus Muscat-Baron,
Dedicated Micros, Malta
"USI's Spray Fluxing Systems provide robust performance for my day-to-day operations. The service that I have received from USI has been exceptional. They stand by their products and are dedicated to improving my wave soldering process through their technology, innovations and continued support."
-Dave Allen,

Revolutionary Optima Fluxing System
There are two goals when spraying flux for wave soldering: to apply flux where it needs to be, and to apply it in the right amount. Every feature of the Optima Fluxing System is designed to achieve these two goals.
The Optima’s revolutionary Ultra-Spray technology achieves better than ± 1% flux deposition variation, and complete flux penetration of all plated-through holes. Smart Motion traversing mechanism, self-tuning ultrasonic generator, and digitally controlled flux flow circuit makes the Optima Fluxing System the best choice for precision spray fluxing applications.
The Optima Fluxing System features:
- Ultimate Precision and Repeatability
- Superior Flux Penetration of Plated-Through Holes Better than ± 1% Flux Deposition Variation
- Maximum Production Uptime
- Self-Cleaning Spray Head
- Selective Spray Fluxing
- Dual Flux Supply (change flux on the fly)

Spray Fluxing for Pb-Free Wave Soldering
Article from Circuits Assembly Magazine
Spray Fluxing applications are not immune from problems during Pb-free solder processing. In fact, good flux chemistry and flux deposition control are critical to successful Pb-free wave soldering.
In the ideal no-clean soldering process, flux applied to the board is consumed in the soldering process, virtually eliminating post-soldering flux residue. If too much flux is applied, excess post-soldering flux residue will result. It is critical to apply the minimum amount of flux required to facilitate soldering. To do so, a spray fluxing system must apply the flux uniformly to the bottom surface of the board and into the through-holes. To maintain this process throughout a production shift, the spray fluxing system must have the capability of repeating the preset flux deposition amount with little variation.

Lead-Free Wave Soldering Case Study
Measuring Through-Hole Penetration with Optima Fluxing System
Lead-free solder alloys do not "spread out" and fill the plated-through holes of circuit boards as well as lead bearing alloys. As the industry moves toward lead-free soldering, applications are more dependent upon good flux chemistry and a robust fluxing system able to deliver flux into all plated-through holes of a circuit board.
Ultrasonic Systems Inc. (USI) and a leading EMS company conducted a recent Case Study to measure the ability of USI’s Optima Fluxing System to achieve complete flux through-hole penetration on extremely wide and thick circuit boards for lead-free assembly.
