Main parts:

1. Solder pot nozzle

2. With a 130-micron orifice controlled by micro drop jet flux sprayer ( Made in Germany)

3. Preheating zone with flashing quartz IR preheater.


System Benefits & Features
• Precise, accurate, reliable soldering of through-hole components in mixed boards with previously soldered SMT components;
• Reduce board processing time as compared with hand soldering;
• Reduce direct labor costs, decrease rework costs, increase consistency over hand soldering through-hole components;
• One, all inclusive system - Flux, Preheat, and Solder
• PC software interface for easy on instrument setup, programming and parameter control
• Instrument programming flexibility and control over preheat, temperature, soldering dwell times, location, direction, and more...
• Off-line programming with photos can and Gerber import software for convenient machine setup
• Variety of Nozzles available for flexibility - Wettable and Specialty Nozzles

• Lead-free compatible.
