The SPX soldering system provides a large soldering range within it’s 24” by 24” frame. This process area does not require any rotation or adjustment in order to reach its capacity. This soldering machine uses precise and reliable servo-driven XYZ axis motion control that articulates the soldering miniwave and flux nozzle beneath the PCB. A thermal performance a soldering miniwave is achieved with the use of a closed loop temperature controlled nitrogen inertion process. RPS offers innovative miniwave nozzle designs for wave stability and defect free performance.

  • Solder Method: Nozzle Motion X-Y-Z Axis
  • Robotics: Closed Loop Servo
  • Performance Cycle: 80 hr/ Pump Clean
  • NozzlesL RPS Gaussian Miniwave


The effectiveness of an RPS soldering system is highlighted by its ability to handle a high mix of changing and often complex assembly requirements, including tall and odd size components, tight keep always, thermal demands and thermal limitation. The RPS Gaussian MiniWave delivers precise and smooth laminar solder for tight keep always and repeatability. RPS N2 DirectHeat for N2 inertion delivers closed loop N2 temperature control from 0-400C. This innovation enables superior thermal capacity at the point of soldering, reducing if not eliminating component risk associated with pre-heat. These and more innovations provide RPS customers with the ability to meet ever changing assembly requirements.



Computer controlled XYZ robotic platform using closed loop servo motion control robotics. Flux and miniwave nozzles articulate below PCB. Programs generated via RPS CamConductor programming package. Program via GUI selection relative to imported JPEG and Gerber data images. Virtually unlimited program storage. PC, keyboard, mouse, monitor and monitor mount, installation, software & nozzles included.
