Combined use of the spray gun which provides ultralow-pressure infinitesimal coating and the servo-motor which controls the guns high-speed swinging movement have achieved uniform and even spray coating.

Flux spraying at point-blank range has greatly improved coating efficiency and reduced outward mist dispersal or particle rebound from PCB, which requires a lot less maintenance work and flux usage.
Flux sub-tank supply control structure enables flux replacement without stopping the machine.
Spray area of X-Y dimensions can be precisely set on the LCD monitor and error messages (e.g. air pressure, flux empty, filter replacement, spray amount anomaly) are also displayed there, which help operators to easily control conditions on production line.
Preheating PCBs (at 60°) right before VOC-free flux coating is very effective in improving soldering quality.
  • Water vapor adhesion to PCBs is decreased by 30%, the interfacial tension becomes low, and solder wettability and uniformity are improved.

  • Water evaporation in the pre-heater unit becomes fast and plastic fluidity in flux is improved.

  • The heat resistance pre-flux on PCBs becomes soft and the compatibility with post-flux is improved.
